Product positioning
Overview
A widely used method for segmenting the areas in which switches are installed calls for three different
classifications: access, distribution, and core. Access switches provide aggregation of end nodes for
connection to a distribution or core switch and are usually found in wiring closets. Distribution
switches aggregate the links from access switches and possibly server farms. Distribution switches
anchor the network in a building, or, for small networks, across a campus. Core switches provide the
focal point of the local network, aggregating the distribution switches, providing connectivity for
central site data centers, and providing connectivity in many cases to the external network.
Regardless of your network’s architecture—whether you have adopted HP ProCurve’s Adaptive
EDGE Architecture with its intelligence at the edge, or perhaps you use a traditional architecture that
concentrates intelligence at the center of the network—you have a choice of wiring topologies to
implement that architecture.
The intelligence and throughput of the HP ProCurve Switch 3500yl, 5400zl, and 6200yl Series make
them suitable for applications at or near the edge of networks of all sizes, or in the center of networks
that are small-to-moderate in size. The Switch 8200zl offers the same ProVision ASIC intelligence and
throughput with a redundant management module design and flexible switch fabric modules for
demanding, high-availability applications, whether at the core, distribution, or edge of your network.
The modular structure of both the HP ProCurve Switch 8200zl and 5400zl Series gives you the
flexibility to tailor the switch to match your topology’s requirements. The HP ProCurve Switch
6200yl, an advanced Layer 3 stackable, is designed to be deployed as an aggregator of traffic from the
edge to the core of the network. The HP ProCurve Switch 6600, an advanced Layer 3 stackable with
front-to-back cooling and integrated redundant power, is specifically designed to be deployed as a data
center top-of-rack switch for high performance server access layer connectivity.
The foundation for all of these switches is a purpose-built, programmable ProVision ASIC that allows
the most demanding networking features, such as QoS and security, to be implemented in a scalable
yet granular fashion. A high-capacity switch fabric, based on the most recent ProVision ASIC
architecture, is integrated with the switch backplane. The HP ProCurve Switch 3500yl, 5400zl, 6200yl,
6600, and 8212zl Series have been designed as a product family, using the ProVision ASICs and
software, providing consistency and scalability across the family.
The ProVision ASICs are aimed at accomplishing several objectives:
• Provide a great engineering balance between feature capabilities, performance, and price
• Bring sophisticated control features to the edge of the network
• Have programmable features that allow future requirements to be accommodated in the ASICs
Key features of the HP ProCurve Switch 3500yl, 5400zl, 6200yl, 6600, and 8200 series include:
• Performance—high-capacity switch fabric (from 115 Gbps to 692 Gbps backplane speed),
bandwidth shaping and control, quality of service, L2 and L3 jumbo frames
• Security—ACLs (per-port or identity-driven); virus throttle; switch CPU protection; detection of
malicious attacks; DHCP protection; BPDU port protection; Dynamic ARP protection; Dynamic IP
lockdown; STP root guard; IP and MAC lockdown/lockout; 802.1X, Web, and MAC user
authentication; USB secure autorun; and management access control (SSH, SSL, TACACS+,
secure FTP)
• Operational flexibility—high-port density in 4U and 7U form factors, Versatile Intelligent Ports
(10/100/1000, PoE-enabled), power supply choices for optimum PoE
• Resiliency—redundant power supplies, hot-swappable/hot-insertable modules, MSTP, switch
meshing, VRRP, OSPF-ECMP
• Layer 2-GVRP, VLAN, Q-in-Q
• IP Routing—RIPv1, RIPv2, OSPF, PIM-SM, PIM-DM, static route
• Solution integration: 8200zl-hosted application/services deployment via HP ProCurve ONE
Services zl Module
• IPv6-host, IPv4/IPv6 dual stack, ACL, QoS, and MLD snooping
• Convergence-IP multicast snooping (data-driven IGMP), LLDP-MED, RADIUS VLAN, PoE
5
• Diagnostic—remote intelligent mirroring, loopback interface, UDLD, sFlow support
• Investment protection—upgradable management engine and CPU (for 5400zl and 8200zl Series),
upgradable to Premium License feature group, add-in modules and power supplies (for 5400zl and
8200zl Series), Versatile Intelligent Ports, programmable ASICs
HP ProCurve Switch 5400zl and 3500yl Series
The HP ProCurve Switch 5400zl and 3500yl series consist of the most advanced intelligent edge
switches in the HP ProCurve product line. The 5400zl series includes 6-slot and 12-slot chassis and
associated zl modules and bundles, and the 3500yl series includes 24-port and 48-port stackables.
With a variety of Gigabit interfaces, integrated Power over Ethernet (PoE) on all 10/100/1000Base-T
ports, 10-GbE capability, and a choice of form factors, the 5400zl and 3500yl switches offer excellent
investment protection, flexibility, and scalability, as well as ease of deployment, operation, and
maintenance.
The 5400zl and 3500yl switches are targeted as enterprise-class wiring closet switches—designed for
low cost with a choice of medium to high port density. Voice, video, and data ready, the HP ProCurve
Switch 5400zl and 3500yl series offer extensive prioritization features that bring full convergence
down to the desktop. Integrated PoE minimizes wiring requirements for VoIP phones and wireless
access points. The HP ProCurve Switch 5400zl and 3500yl series provide fine-grained security at the
edge of the network to lock out external threats, yet provide appropriate access to employees and
guests. Collectively, these features make the 5400zl and 3500yl switches well-suited for the access tier.
For some customers, the Layer 3 features and redundant power supply features of the HP ProCurve
Switch 5400zl series also make it well-suited as a distribution switch. New to the 5400zl and 3500yl
series is the optional deployment of a Premium License feature group as opposed to the standard
offerings of the Intelligent Edge feature group. The Premium License contains all of the Intelligent
Edge features plus additional features oriented towards routing that are useful when deploying the
switch at the distribution level of the network. The Premium License feature group includes protocols
such as PIM-SM, PIM-DM, OSPF-ECMP, and VRRP.
HP ProCurve Switch 6200yl-24G-mGBIC
The HP ProCurve Switch 6200yl-24G-mGBIC is an advanced Layer 3 stackable in 1U height. It has
24 mini-GBIC slots and an expansion slot for an optional 4-port 10-GbE module. Designed to be
deployed as an aggregator of traffic from the edge to the core of the network, this switch supports a
variety of Gigabit mini-GBICs, such as SX, LX, LH, and 1000Base-T. The Premium License feature
group is standard on the HP ProCurve Switch 6200yl-24G-mGBIC.
Like the 5400zl and 3500yl series switches, the foundation for this switch is a purpose-built ProVision
ASIC that allows the most demanding networking features, such as QoS and security, to be
implemented in a scalable yet granular fashion. With its high-performance architecture, 10-GbE
capability, and programmable ASIC, this switch offers excellent investment protection, flexibility, and
scalability.
ProVision ASIC architecture
The ProVision application-specific integrated circuit (ASIC) architecture is the latest generation HP
ProCurve ASIC technology and is used in the HP ProCurve Switch 5400zl, 3500yl, and 6200yl series.
The ProVision ASIC architecture consists of multiple network chips interconnected by an active
crossbar consisting of the fabric chip. A network chip is implemented on each of the various line
interface modules (also known as line cards). The fabric chip is integrated on the switch backplane,
which helps reduce the overall size of the switch.
Each network chip represents a node in the system with “links” connecting to the interconnect fabric.
Each link provides approximately 28.8 Gbps of data bandwidth. In addition, a management module
with a dedicated CPU provides communications control between the network chips and fabric chips.

Figure 1. ProVision ASIC Architecture for HP ProCurve Switch 5406zl
The diagram above illustrates an example of the logical interconnection of the ProVision ASICs on the
6-slot 5406zl series switch. All of the key elements are connected to the active backplane. The active
backplane contains the switch fabric and distributes power to all modules. The HP ProCurve Switch
5412zl, 3548yl, 3524yl, and 6224yl have similar architectural components. The primary difference in
the illustration would be the number of ports supported.
Inside the ProVision ASIC Architecture
Each line interface module contains a full ASIC-based Layer 3 routing switch engine as well as Layer
4 filtering and metering. These new ProVision ASICs are HP ProCurve’s 4th-generation switching
ASICs. This network switch engine, in the ProVision ASICs, provides all the packet processing: Layer
2 and Layer 3 lookups; filtering and forwarding decisions; VLAN, trunking, and priority queuing
determinations. The ProVision ASIC on each line card contains its own CPU. These features of the
ProVision ASIC are common for all products in the HP ProCurve Switch 5400zl, 3500yl, and 6200yl
series.
Classification and lookup
When a packet first comes in, the classifier section determines the packet characteristics, its addresses,
VLAN affiliation, any priority specification, etc. The packet is stored in input memory; lookups into
the table memory are done to determine routing information; and a ProVision ASIC-specific packet
header is created for the packet with this information. This header is then forwarded to the Policy
Enforcement Engine.
7
Policy Enforcement Engine
The ProVision ASICs on each line interface module contain the Policy Enforcement Engine. This
engine provides fast packet classification to be applied to ACLs, QoS, Rate Limiting, and some other
features through an onboard TCAM. Some of the variables that can be used include source and
destination IP addresses (can follow specific users), TCP/UDP port numbers, and ranges (apply ACLs
to an application that uses fixed port numbers or ranges). Over 14 different variables can be used to
specify the packets to which ACL and QoS rules, rate limiting counters, and others are to be applied.
Partially implemented in the initial software release, the Policy Enforcement Engine will provide a
common front end for the user interface to ACLs, QoS, rate limiting, and some other services. In
subsequent software releases for the switches, more features can take advantage of the Policy
Enforcement Engine to provide a powerful, flexible method for controlling the network environment.
For example, traffic from a specific application can be raised in priority for some users, blocked for
some other users, and limited in bandwidth for yet other users. After the Policy Enforcement Engine,
the header is then forwarded to the programmable section of the network switch engine.
Network switch engine programmability
Each ProVision ASIC switch engine contains multiple programmable units, making them truly
Network Processor Units (NPUs). One of the functions of the NPU is to analyze the header of each
packet as it comes into the switch. The packet’s addresses can be read with the switch making
forwarding decisions based on this analysis. For example, if a packet’s 802.1Q tag needs to be changed
to re-map the packet priority, the ProVision ASIC needs to look at each packet to see if any particular
one needs to be changed. This packet-by-packet processing has to occur very quickly to maintain
overall wire-speed performance – a capability of the ProVision ASICs.
To broaden the flexibility of the ProVision ASICs, a programmable function is included for its packet
processing. This NPU function allows the HP ProCurve designers the opportunity to make some future
changes or additions in the packet processing features of the ASIC by downloading new software to it.
Thus, new features needing high-performance ASIC processing can be accommodated, extending the
useful life of the switch without the need to upgrade or replace the hardware. In the first release of the
HP ProCurve Switch 5400zl, 3500yl, and 6200yl series, the NPU function within the ProVision ASICs
is totally unused, awaiting future upgrades.
The concept of adding the programmable functionality of the NPU within a switching ASIC was
originally designed and implemented in the popular HP ProCurve Switch 4000M family introduced in
1998. The programmable capability of the HP ProCurve Switch 5300xl was a second-generation
design based on the original HP ProCurve Switch 4000M implementation. The programmable
capability was used to give both the HP ProCurve Switch 4000M and Switch 5300xl new ASIC-related
features well after initial release of those products. The customers’ investments in the HP ProCurve
Switch 4000M and 5300xl are preserved by new functionality not otherwise possible without the ASIC
NPU programmability.
Being based on the HP ProCurve Switch 4000M and 5300xl implementations, the NPU capabilities of
the ProVision ASICs used in the HP ProCurve Switch 5400zl, 3500yl, and 6200yl series are a thirdgeneration design.
Fabric Interface
After the packet header leaves the programmable section, the header is forwarded to the Fabric
Interface. The Fabric Interface makes final adjustments to the header, based on priority information,
multicast grouping, etc., and then uses this header to modify the actual packet header as necessary.
The Fabric Interface then negotiates with the destination ProVision ASICs for outbound packet buffer
space. If congestion is present on the outbound port, WRED (weighted random early detection) can be
applied at this point as a congestion-avoidance mechanism. Finally, the ProVision ASICs Fabric
Interface forwards the entire packet through the Fabric-ASIC to an awaiting output buffer on the
ProVision ASICs that controls the outbound port for the packet. Packet transfer from the ProVision
ASICs to the Fabric-ASIC is accomplished using the 28.8 Gbps full-duplex backplane connection, also
managed by the Fabric Interface.
8
ProVision ASIC CPU
Each ProVision ASIC contain its own CPU for learning of Layer 2 nodes, packet sampling for the
XRMON function, handling local MIB counters, and running other module-related operations. Overall,
the local CPU offloads the master CPU by providing a distributed approach to general housekeeping
tasks associated with every packet. MIB variables, which need to be updated with each packet, can be
done locally. The Layer 2 forwarding table is kept fresh through the use of this CPU. Other per-port
protocols, such as Spanning Tree and LACP, are also run on this CPU. The local CPU, being a fullfunction microprocessor, allows functionality updates through future software releases.
Fabric ASIC
The Fabric ASIC, which is located on the backplane of the switch, provides the crossbar fabric for
interconnecting the modules together. The use of a crossbar allows wire-speed connections
simultaneously from any module to any other module. As mentioned in the ProVision ASICs section,
the connection between the Fabric-ASIC and each line interface module’s ProVision ASIC is through a
28.8 Gbps full-duplex link.
Management subsystem
The management subsystem is responsible for overall switch management. The management
subsystem consists of a CPU, flash memory to hold program code, processor memory for code
execution, status LEDs and pushbuttons, a console interface, and other system support circuitry to
interface and control each line interface module. In the case of the 5400zl series switch, the
management subsystem is on a module that is removable/upgradable. Each 5400zl series chassis
requires one management module to function. For the HP ProCurve Switch 3500yl and 6200yl series,
the management subsystem is an integrated component.
Advanced capabilities of the product family
The HP ProCurve Switch 5400zl, 3500yl, and 6200yl series product family includes a number of
advanced capabilities that offer a highly reliable, robust chassis data environment that leads to
increased network uptime, keeping overall network costs down.
Versatile Intelligent Port (VIP)
All Gigabit copper ports are PoE enabled and tie into the overall capabilities of the switch, such as the
Policy Enforcement Engine. Having the VIP, any port can be connected to any place in the network. If
a PC needs Gigabit connectivity, it is available. If an AP needs PoE, it is there. And if for some reason,
these ports need to be swapped on the switch, that can be done by just moving the cables at the switch
or patch panel.
The Versatile Intelligent Port provides a high degree of flexibility, makes troubleshooting easier, and
provides a high degree of future-proofing.
ProVision hardware resiliency
Many functions required in a switch have been implemented in the single ASIC on the module. What
requires a number of chips in other vendor products is achieved in a single ProVision ASIC, which
keeps the part count low and increases overall reliability of the module by a significant degree.
Another engineering aspect in the ASIC is hardware error detection with correction in software for the
memory used by the switch. This capability includes the memory used for forwarding the network
traffic such as the routing and forwarding tables, the Policy Enforcement Engine information, multicast
tables, and other data structures. Traffic sent across the backplane uses a protocol to check that there is
space available at the destination module so that fabric data is not lost.

HP ProCurve Switch 5400zl Series
The HP ProCurve Switch 5400zl series is a high-end edge switch. This switch series has been designed
to be a feature-oriented high-performance wiring closet switch. It can also be used as a low-to-medium
distribution switch when used with Premium License, described later in this document.
The 5400zl series is the latest generation of managed chassis products from HP ProCurve. The 5400zl
series follows in the evolution of HP ProCurve managed chassis switches, featuring Power over
Ethernet (PoE) on every copper port, chassis flexibility in the stackable price range, and a scalable
architecture.
The 5406zl and 5412zl switches each require a single management module that initializes, controls,
and monitors the various line and service modules and the switch fabric. The 5406zl switch has six
slots available for population with interface modules, whereas the 5412zl switch has twelve slots
available. The 5406zl and 5412zl switches support the same line interface and service modules. The
line interface modules are the 24-port 10/100/1000, 20-port 10/100/1000 + 4-port mini-GBIC, 24-port
mini-GBIC, 4-port 10-GbE X2, and 4-port 10-GbE CX4. The service modules include the Wireless
Edge Services (WESM) zl Module and the HP ProCurve ONE Services zl Module. The 5406zl switch
supports up to two internal power supplies, and the 5412zl switch supports up to four internal power
supplies. The power supplies can be used for purposes of power redundancy or for additional PoE
requirements.
The base configuration for the 5406zl (J8697A) includes a management module, Intelligent Edge
software, and 6 open slots. Line interface modules can be added as needed for connectivity. The base
configuration for the 5412zl (J8698A) includes a management module, Intelligent Edge software, and
12 open slots. Line interface modules can be added to the 5412zl as needed for connectivity. Note that
NO power supplies ship with base chassis products—they must be ordered separately.
The management module monitors the ambient temperature of the system. In the event the temperature
exceeds a product-specified threshold, an SNMP trap and event log entry are generated.

However, when the management module is removed, all ports lose communication and the system will
be powered down.
Figure 3. HP ProCurve Switch 5406zl chassis layout
Figure 4. HP ProCurve Switch 5412zl chassis layout
12
The internal power supplies are inserted in the back slots. These slots are labeled PS1 and PS2 on the
5406zl and PS1 through PS4 on the 5412zl. A power supply is hot-swappable provided at least one
other power supply is operational. If the 5412zl has only two power supplies and one of them fails,
then only the upper six slots (slots A through F) will receive power.
Power supplies
There are two different power supplies available for the HP ProCurve Switch 5400zl series. Both
power supplies provide system power (the power needed to run the switch itself) and PoE power (the
power sent down the Ethernet cable to power the device at the other end). The only difference between
the two supplies is the amount of PoE power available from the supply.
All HP ProCurve Switch 5400zl series chassis use the same power supplies. There are two internal
power supplies available:
• 875W (110V/220V)
• 1500W (220V)
As indicated in the following figure, the internal power supply provides both system power as well as
PoE. The HP ProCurve Switch 5400zl series, as well as the 3500yl series, can power any device that
adheres to the IEEE 802.1af standard. In addition, devices using pre-standard Cisco PoE power can
also be powered. The switches will automatically detect what type of power and how much is needed
when a compatible device is plugged into the port.
It is recommended that you use the same power supply model for all power supplies installed in a
given 5400zl series chassis.

The internal power supplies provide system power for all internal components (+12V output within +/5% tolerance, regulated) and power for PoE ports (-48V output within +/- 5% tolerance, regulated),
which meets isolation and noise requirements of the IEEE 802.3af specification.
13
Both internal supplies have over-current, over-temperature, and over-voltage protection, as well as
integrated fans. Hot swapping is allowed, taking into account that disconnecting the power supplies
may interrupt PoE operation.
An external power shelf, the HP ProCurve Switch zl Power Supply Shelf, is available to house up to
two switch zl power supplies. The power shelf supplies can be connected to one or two switch zl’s to
provide additional PoE power, either to power additional PoE-powered devices, or to provide more
power for PoE power redundancy. The supplies in the power shelf are connected to the switch(es) via
one or two 2m EPS cables. The PoE power provided is added to the internal power supply PoE power
to figure the total amount of PoE power to the ports in the switch.
While the connectors on the EPS connector cable will fit the connectors on the 3500 switches, no
power will flow from the power shelf. Extra PoE power for the 3500 switch can be obtained with the
HP ProCurve 620 Redundant/External Power Supply.
Fan tray
The fan tray assembly contains the cooling fans for the interior of the 5400zl series chassis, but
excludes the chassis power supplies, which have their own internal cooling fans. The 5406zl fan tray
consists of 2 variable-speed fans, and the 5412zl fan tray consists of 4 variable-speed fans. The fan
speed is based on the sensed ambient temperature of the chassis.
The fan tray is mounted on the left side of the chassis (from a front-view perspective), and the fans
draw air through ventilation holes to the left and blow the air out through ventilation holes to the right
(side-to-side airflow).
The fan tray is hot-swappable in the 5406zl and 5412zl. It can be removed and replaced without
removing power from the switch. However, the new fan tray should be installed immediately after
removing the old fan tray to avoid overheating and automatic switch shutdown within three minutes.
14
In the event of an individual fan failure, an SNMP trap and event log entry are generated.

Power supply configurations
The Switch 5406zl provides slots for two internal supplies and requires at least one internal power
supply. An additional internal power supply may be added for 1+1 redundancy system power or to
provide additional PoE power.
The Switch 5412zl provides slots for four internal supplies and requires at least two internal power
supplies. Two additional internal power supplies may be added for 1+1 system power redundancy or
to provide additional PoE power.
1+1 power supply redundancy implies providing twice the minimum number of supplies required to
power the system.
The table below shows the HP ProCurve Switch 5400zl series minimum and maximum internal power
supply configurations, as well as internal combined power with external power shelf configurations.

Table 1. Minimum and maximum power supply support
When deciding on which and how many power supplies to configure for a 5400zl series switch, the
following criteria can be used to guide the decision:
• How much power will be required for each PoE port, full (15.4 watts) or phone (8 watts) power?
• How many network devices will require power (how many PoE ports are needed)?
• Is redundant power required (for internal power and/or PoE power)?
Note that the power supplies provide a “pool” of power for all line interface modules to draw from;
that is, PoE power is not limited on a per line interface module basis.

located on the front panel of the HP ProCurve Switch 6200yl-24G-mGBIC. To connect to the console,
a standard null modem cable is used that is equivalent to the cable used for other HP ProCurve
switches like the HP ProCurve 5300xl series.
LED status indicators
The front panel of the HP ProCurve Switch 6200yl-24G-mGBIC has the same LED status indicators as
the HP ProCurve Switch 3500yl series. Refer to the appendix for information about the LED status
indicators.
Additional line interface module
The HP ProCurve Switch 6200yl-24G-mGBIC supports one additional line interface module, the HP
ProCurve Switch yl 10-GbE 2p CX4 + 2p X2 Module. This module is installed on the back panel of
the switch. This is the same module that is supported by the HP ProCurve Switch 3500yl series. Refer
to the section covering the HP ProCurve Switch 3500yl series for details about this line interface
module.

Overview of features and benefits
The HP ProCurve Switch 5400zl, 3500yl, and 6200yl series use the same software image base. For the
HP ProCurve Switch 6200yl, the Premium License feature group is standard. For the HP ProCurve
Switch 5400zl and 3500yl series, you have the choice of using the Intelligent Edge feature group or the
Premium License feature group for an additional fee. The Premium License feature group supports
additional aggregation layer features: Q-in-Q, PIM-SM, PIM-DM, OSPF-ECMP, and VRRP. The
primary differences among these switch families are hardware related and include such aspects as port
density and the number of power supplies and fans.
The following summary of features and benefits applies to the HP ProCurve Switch 5400zl, 3500yl,
and 6200yl series. Any differences that exist among the switches are noted.
Performance

associated memory buffer that best meet the requirements of network applications.
Security features
• Virus Throttle: connection Rate Filtering thwarts virus spreading by blocking routing from certain
hosts exhibiting abnormal traffic behavior
• ICMP throttling: defeats ICMP denial-of-service attacks by enabling any switch port to
automatically throttle ICMP traffic
• Filtering capabilities: include fast, flexible Access Control Lists (ACLs), up to 3,000 per module (in
later release, more precise detailed control via the fast Policy Enforcement Engine), source port,
multicast MAC address, and other protocol-based filtering capabilities
• Switch CPU protection: provides automatic protection against malicious network traffic trying to
shut down the switch
• Detection of malicious attacks: monitors ten types of network traffic and sends a warning if an
anomaly occurs, signaling the detection of a potential malicious attacks
• USB secure autorun: uses USB flash drive to deploy, troubleshoot, or update switches; works with
secure credential to prevent tampering
• STP root guard: protects STP root bridge from malicious attack or configuration mistakes
• DHCP protection: blocks DHCP packets from unauthorized DHCP servers, preventing denial-ofservice attack
• BPDU port protection: blocks Bridge Protocol Data Unit (BPDU) on ports that do not require
BPDU, preventing forged BPDU attack

accept up to 32 sessions of IEEE 802.1X, Web, and MAC authentications
• Access control lists (ACLs): provide filtering based on the IP field, source/destination IP
address/subnet, and source/destination TCP/UDP port number on a per-VLAN or per-port basis
29
• Identity-driven ACL: enables implementation of a highly granular and flexible access security
policy specific to each authenticated network user
• Port security: prevents unauthorized access using MAC address lockdown
• MAC address lockout: prevents configured particular MAC addresses from connecting to the
network
• Source-port filtering: allows only specified ports to communicate with each other
• Security banner: displays customized security policy when users log in to the switch
• Management Interface Wizard: CLI-based step-by-step configuration tool to ensure that
management interfaces such as SNMP, telnet, SSH, SSL, Web, and USB are secured to desired
level
• Management access:
– All access methods—CLI, GUI, or MIB—are securely encrypted through SSHv2, SSL, and/or
SNMPv3
– RADIUS and TACACS+: can require either RADIUS or TACACS+ authentication for secure
switch CLI logon
– Secure FTP: allows secure file transfer to/from the switch and protects against unwanted file
downloads or unauthorized copying of switch configuration file
QoS functions
Layer 4 prioritization: enables prioritization based on TCP/UDP ports
Traffic prioritization: allows real-time traffic classification into 8 priority levels mapped to 8 queues
Bandwidth shaping using:
• Rate limiting: per-port ingress-based enforced bandwidth maximums
• Guaranteed minimums: per-port, per-queue egress-based guaranteed bandwidth minimums
Class of Service (CoS): sets 802.1p priority tag based on IP address, IP Type of Service (ToS), L3
protocol, TCP/UDP port number, source port, and DiffServ
Policy Enforcement Engine: Policy Enforcement Engine is user configured to select packets that are
then forwarded or dropped (based on ACLs, QoS, and Rate Limiting). The engine is fast, and can look
for multiple variables, such as an IP address and port number, in a single pass through a packet. It
provides a common user experience regardless of which switch the user is connected to.
Advanced classifier-based QoS:
• Provides finer granularity with multiple match criteria to select and prioritize network traffic
• Integrates QoS functions: select traffic for prioritization and remote mirroring, setting priority, QoS
policy, and rate limit

High availability and redundancy
• VRRP: Virtual Router Redundancy Protocol (requires Premium License) allows groups of two
routers to dynamically back each other up to create highly available routed environments
• 802.3ad LACP: Link Aggregation Control Protocol and HP ProCurve trunking support up to 36
trunks, each with up to 8 links (ports) per trunk
• Port trunks, or link aggregation groups, can operate across multiple modules to increase
redundancy.
• Supports various redundant power supply configurations:
– The 5406zl switch provides slots for two internal supplies. This can provide 1+1 redundancy for
both PoE and system power needs.
– The 5412zl switch provides slots for four internal supplies. This can provide 1+1 redundancy
similar to the 5406zl switch. You can use the internal supplies for 1+1 backup; two backing up
two for both PoE and system power needs.
• Hot-swappable/Hot-insertable line interface modules, so as not to interrupt network operation
• Management module is removable/upgradable: The switch does not have to be powered off to
remove a management module from a 5400zl series. However, when the management module is
removed, all ports will lose communication and the system will be powered down.
31
• Server-to-Switch Distributed Trunking: enables load-balancing and increases resiliency between a
server and multiple switches. This feature allows a server to connect to multiple switches with one
logical trunk that consists of multiple physical connections.
• Other Layer 2 and Layer 3 redundant protocols include MSTP, HP ProCurve switch meshing, and
OSPF-ECMP.
Management
• Remote intelligent mirroring: mirrors selected ingress/egress traffic based on ACL, port, MAC
address, or VLAN to a local or remote 8200/6200/5400/3500 switch anywhere on the network
• RMON, XRMON, and sFlow: provide advanced monitoring and reporting capabilities for statistics,
history, alarms, and events.
• Command authorization: leverages RADIUS to link a custom list of CLI commands to individual
network administrator’s login; also provides audit trail
• LLDP: Link Layer Discovery Protocol allows automated device discovery for easy mapping by
network management applications.
• Friendly port names: allow assignment of descriptive names to ports.
• Dual flash images: provide independent primary and secondary OS files for backup while
upgrading
• Multiple configuration files: allows multiple configuration files to be stored to flash image
• Uni-Directional Link Detection (UDLD): monitors cable between two switches and shuts down the
ports on both ends if the cable is broken, turning the bi-directional link into uni-directional; this
prevents network problems such as loops.
• Configuration, monitoring, and management tasks can be performed using the CLI (through direct
console or Telnet) connection, Web browser, Menu interface, and HP ProCurve Manager.
• MSTP pre-configuration: reduces MSTP configuration complexity and enhances management
productivity
• Transceiver pre-configuration: streamlines deployment of switches in remote locations
Diagnostics
• Core memory dump: preserves system information if the switch failed so that the information can
be analyzed for diagnostic purposes
Future-proofing
• Versatile Intelligent Port implies all gigabit copper ports on the 5400zl and 3500yl series are PoE
enabled.
• The 5400zl series chassis management module is upgradable in order to meet future needs for
processing power.
• Programmable ASICs allow some future requirements to be implemented without replacing the
switch.
• Intelligent Edge features can be upgraded to Premium License features on the 5400zl and 3500yl
series, allowing an edge switch to be redeployed as a distribution switch.

Per-port buffer sizes
The HP ProCurve Switch 5400zl, 3500yl, and 6200yl series have eight hardware queues to which
prioritized traffic can be assigned. Software can designate a certain amount of output memory buffer
for each queue to minimize the impact from events that exceed line rate such as bursty network traffic.
Users can choose to configure the number of queues—2, 4, or 8—so that they can optimize the amount
of memory buffer per queue for their applications. For example, if a user has only 2 priorities on the
network, that user should configure for 2 queues so that all the buffer memory is assigned to only 2
queues. The table below identifies the buffer sizes allocated on a per-port basis to the normal and other
priority queues in each configuration.

Routing and forwarding tables
The HP ProCurve Switch 5400zl, 3500yl, and 6200yl series have several routing and forwarding table
features that enhance routing and switching performance.
Every line interface module has its own “best match prefix” routing table that contains IP routes and is
used for determining how to route the vast majority of incoming packets. Using the best match prefix
routing table is extremely fast and enables wire-speed routing to be achieved.
If the best match prefix routing table does not contain an entry that can be used to determine the route
of a received packet, then the main routing table is used. The main routing table can contain up to
10,000 routing table entries.
For Layer 2 forwarding, each switch has a forwarding or MAC table that can contain up to 65,536
entries.
36
Optimizing the 10-GbE port configuration
The 10-GbE modules (J8707A, J8708A, and J8694A) used in the HP ProCurve Switch 3500yl, 5400zl,
and 6200yl series are designed to deliver full 10 Gbps wire-speed to each port, where either one or two
ports are in a linked state with another device. When three or four 10-GbE ports are in a linked state,
the module supports an aggregate bandwidth of 28.8 Gbps across the linked ports.
As illustrated in the figure below, internally, there are two 14.4-Gbps channels between each 4-port 10GbE module and the switch fabric.
Figure 12. 10-GbE module architecture showing ports grouped by 14.4 Gbps channel
• When any two 10-GbE ports on a given module are in a linked state, each port automatically
operates on its own channel, which guarantees 10 Gbps of bandwidth for each port.
• When more than two ports of a 10-GbE module are in a linked state, ports 1 and 4 are statically
mapped to share one 14.4 Gbps channel, while ports 2 and 3 are statically mapped to share the other
14.4 Gbps channel.
– If only one port in a given channel is in a linked state, then that port operates at wire-speed and the
other port uses no bandwidth.
– If both ports in a given channel are in a linked state, then the 14.4 Gbps of bandwidth is balanced
fairly between the two ports
For example, in an application where three ports on the module are needed and it is important to ensure
that port 1 always has a full 10 Gbps available, the connection choices shown in the next figure would
be used.
37
Figure 13. Approach for guaranteeing 10 Gbps on a specific port
Connection choices are also important where equally balanced bandwidth is needed, such as in a
Virtual Router Redundancy Protocol (VRRP) application. This scenario is illustrated in the next figure.
Figure 14. Guaranteeing equally balanced bandwidth in a VRRP environment
38
Throughput and latency performance data
The following three tables describe the performance capabilities of the 10 Gbps, 1 Gbps, and 100
Mbps line interface module ports of the HP ProCurve Switch 5400zl, 3500yl, and 6200yl series.
Over a range of packet sizes from 64 bytes to 1518 bytes, the performance levels achieved are
described in terms of the following metrics:
• Throughput level percentage achieved when performing Layer 2 switching and Layer 3 routing;
100% in all cases
• Throughput in the form of the number of packets per second when performing Layer 2 switching
and Layer 3 routing
• Average per-packet latency in microseconds when performing Layer 2 switching and Layer 3
routing. These values shown are listed for both First In First Out (FIFO) and Last In First Out
(LIFO) processing. The LIFO values represent the packet transmit time, whereas the FIFO values
include the switch decision time and the packet transmit time.
• Percentage of packets dropped in a full mesh configuration; 0% in all cases
The following measurements were performed by HP ProCurve using test equipment manufactured by
Ixia Communications (www.ixiacom.com). In these tests, the maximum number of supported ports on
the HP ProCurve Switch 5412zl was used. Proportional performance results at 100% of throughput are
achieved on the HP ProCurve Switch 5406zl, 3500yl-24G-PWR, 3500yl-48G-PWR, and 6200yl-24GmGBIC for the maximum number of ports supported by each of those models. The 100 Mbps table is
not applicable to the HP ProCurve Switch 6200yl-24G-mGBIC, since only 1 Gigabit and 10 Gigabit
ports are supported.

10 Gigabit performance traffic patterns
In the prior table, the performance levels for 10 Gigabit ports assume the underlying traffic patterns
reflect either one of the following minimum conditions to achieve wire-speed throughput.
• A single source traffic stream with an average packet size of 88 bytes or larger
• Two or more source traffic streams of any packet size down to the minimum value of 64 bytes
In the unlikely case where the average packet size is consistently smaller, the throughput will be less
than wire-speed. For example, consider a worst case scenario where the average packet size is 64
bytes. This would result in a throughput of approximately 70% to 80% of the rated wire-speed
capacity. HP ProCurve considers such minimum-sized, packet traffic scenarios being realized over an
extended period of time to be extremely atypical and unlikely to be experienced by customers in the
field.
Note that the limits described above do not apply to Gigabit ports.
Throughput test
A fully meshed performance test sends packets from each port to every other port during the test. This
type of test exercises both the modules and the backplane. These tests show the HP ProCurve Switch
5400zl, 3500yl, and 6200yl series to be wire-speed on all ports simultaneously.
Latency measurements
Latency is commonly measured as the amount of time it takes for a byte inside a packet to enter and
then leave the switch. Latency statistics are typically documented as including both the processing time
of the switch as it makes its forwarding decision and the time for the packet itself to enter and leave the
switch. In the prior tables, this definition of latency corresponds to the FIFO latency statistics. The
LIFO latency statistics that are also listed in the tables represent only the packet transmission time.
Almost all switches currently on the market are store and forward, so the entire packet is received into
the switch before the switch begins to transmit the packet out the egress port. Including the packet
receive time in the FIFO latency statistics is appropriate since this extra time is a contributing
component of the overall transit time of the packet as it moves through the network.
The latency figures for the HP ProCurve Switch 5400zl series are consistently low. Latencies this low
will not be a factor in general network operation, even with streaming video or VoIP applications. The
LIFO latency values are fairly consistent across all packet sizes because ingress and egress packet
processors operate on the header of the frame (not the whole frame), while the full frame is buffered in
and out of packet buffer memory. Memory transfers are scheduled to fit a full 1518-byte frame, so
frames are transferred in and out of memory in approximately the same amount of time regardless of
packet size. While the frame headers are being looked up and actions required for the frame on egress
are being coordinated among interface modules, the frame is transferred through the switching fabric
module.
The architecture used for ACL storage and processing is different among the HP ProCurve switches
listed in table 9. The HP ProCurve Switch 5400zl and 3500yl series have the additional performance
advantage gained through the use of the TCAM (see the appendix for more details). The HP ProCurve
Switch 5400zl and 3500yl series also have an additional performance advantage in the processing of
the routing table through the use of a “best match prefix” table (described previously in this section).
The HP ProCurve Switch 5400zl and 3500yl series support the use of PIM-SM and PIM-DM, but not
concurrently.

Appendix A: Premium License
This section of the Technical Overview provides additional background information about the HP
ProCurve Switch 5400zl, 3500yl, and 6200yl series products.
Intelligent Edge and Premium License
Introduced with the HP ProCurve Switch 5400zl and 3500yl series is the option of implementing
Intelligent Edge or Premium License. For the HP ProCurve Switch 6200yl, Premium License is
standard due to its recommended deployment at the distribution level as an aggregator of traffic from
the edge to the core.
In the case of the 5400zl and 3500yl switches, Premium License implies the switch can run
aggregation layer features that include Q-in-Q, OSPF-ECMP, PIM-SM, PIM-DM, and VRRP. All the
product features are included in the firmware image installed on the switch, but Premium License
features require a license for those features to be enabled.
For HP ProCurve, moving to Premium License creates a distinction between the terms “Upgrade” and
“Update.” Upgrade means licensing Premium License features which add significant new functionality
to the switch for an additional fee. Update means installing the latest version of firmware such as bug
fixes.
HP ProCurve has taken a flexible approach with Premium License. For example, in the 5400zl and
3500yl series, all switches can run the Intelligent Edge feature group initially. A switch can later be
upgraded to run the Premium License feature group, if its advanced features are needed. Also, if
network configurations change, a Premium License can be transferred to another switch, as long as the
license stays in the same hardware family.
There are two ways you can manage Premium Licenses:
• Manually—You use the My ProCurve portal and the switch CLI. This is a good method to use if
you are managing a small number of licenses and do not already use the HP ProCurve Manager
network management software.
• PCM—You use HP ProCurve Manager to perform the most common licensing functions. If you
are already using PCM, this is more convenient than the manual method. There is a free copy of HP
ProCurve Manager on the CD-ROM that accompanies your premium license.
For the manual method, you will require manager privilege level access on the switches to perform
several CLI commands related to licensing. For the PCM method, PCM requires configured access to
the devices.
43
Two methods for managing Premium Edge licensing on ProCurve Switch
5400zl and 3500yl series
• Manually using ProCurve web portal and CLI commands
– Good for small number of licenses, requires manager level access
• ProCurve Manager (PCM)
– Convenient for may licenses, handles most aspects
– Requires PCM configured for access to each device and My ProCurve account
information
Either method requires that you be registered on the My ProCurve web portal

To use HP ProCurve Manager to install a Premium License, you first select the 5400zl or 3500yl
switch in the PCM navigation tree and right-click it. Then, you select Config Manager > License
Software on the pop-up menus. The easy-to-use License Configuration Wizard window will then be
displayed so that you can start the license installation process.
Note that before attempting to install a Premium License using HP ProCurve Manager, HP ProCurve
Manager must be configured for device access to the 5400zl or 3500yl switch and your “My
ProCurve” account (member ID and password) information.
44
On a subsequent window, you select premium-edge for the Feature Group and type the registration ID
you received with the purchase of the Premium License. The registration ID is found on a plastic
laminated card that is shipped with the HP ProCurve switch.
After you agree to the terms of the License Agreement, the wizard will display the status of the license
installation process. As part of this process the following events occur:
• First, the Hardware ID is retrieved from the switch.
• Secondly, the license key is retrieved from the My ProCurve Web portal.
• Lastly, the Premium License feature group is activated and the license is installed.
Appendix B: Policy Enforcement Engine
The ProVision ASIC architecture used in the HP ProCurve Switch 5400zl, 3500yl, and 6200yl series
brings a number of advanced capabilities to the network that offer a highly reliable, robust
environment that leads to increased network uptime, keeping overall network costs down. One major
feature is the ProVision Policy Enforcement Engine which is implemented in the ProVision ASIC of
each line interface module.
45
Policy Enforcement Engine benefits
The Policy Enforcement Engine has several benefits:
• Granular policy enforcement
The initial software release on these products takes advantage of a subset of the full Policy
Enforcement Engine capabilities, which will provide a common front end for the user interface to
ACLs, QoS, Rate-Limiting, and Guaranteed Minimum Bandwidth controls. Fully implemented in
later software releases, the Policy Enforcement Engine provides a powerful, flexible method for
controlling the network environment. For example, traffic from a specific application (TCP/UDP
port) can be raised in priority (QoS) for some users (IP address), blocked (ACL) for some other
users, and limited in bandwidth (Rate-Limiting) for yet other users.
The Policy Enforcement Engine provides fast packet classification to be applied to ACLs and QoS
rules, and Rate Limiting and Guaranteed Minimum Bandwidth counters. Parameters that can be
used include source and destination IP addresses, which can follow specific users, and TCP/UDP
port numbers and ranges, which are useful for applications that use fixed port numbers. Over 14
different variables can be used to specify the packets to which ACL, QoS, Rate Limiting, and
Guaranteed Minimum Bandwidth controls are to be applied.
• Hardware-based performance
As mentioned above, the Policy Enforcement Engine is a part of the ProVision ASIC. The packet
selection is done by hardware at wire-speed except in some very involved rules situations.
Therefore, very sophisticated control can be implemented without adversely affecting performance
of the network.
• Works with Identity Driven Manager
HP ProCurve Identity Driven Manager (IDM) provides the centralized command from the center to
define the user policies to be used with each user. The IDM policy requests sent down to the switch
are used to set up the user profile in the Policy Enforcement Engine so that the per-user ACL, QoS,
and Rate-Limiting parameters can be used from the actual policy defined in IDM.
Wire-speed performance for ACLs
At the heart of the Policy Enforcement Engine is a memory area called the Ternary Content
Addressable Memory (TCAM) that is contained within the ProVision ASIC along with the
surrounding code for the Policy Enforcement Engine.
It is this specialized memory area that helps the ProVision ASIC achieve wire-speed performance
when processing ACLs for packets. In fact, multiple passes through the TCAM can be performed for
packet sizes that are typically found in customers’ production networks. For the typical network, the
average packet size will tend to be about 500 bytes. When maximum lookups are enabled, the
ProVision ASIC performance is optimal for an average packet length of 200 bytes or more, which
includes the range of packet sizes in typical networks.
The TCAM can support approximately 3,000 data entries that may be used to represent various traffic
controls, including ACLs. For most customers, this quantity of entries will be more than adequate to
ensure wire-speed performance for ACL processing. Keep in mind that each ACL entry may consist of
multiple criteria such as a specific IP address and TCP or UDP port number.
In the initial release, the contents of the TCAM are common among the multiple line interface modules
that a switch may have installed. For example, a HP ProCurve Switch 5406zl may have up to 6 line
interface modules, and a HP ProCurve Switch 5412zl may have up to 12 line interface modules.
46
Appendix C: Power over Ethernet
The IEEE 802.3af standard for Power over Ethernet (PoE) enables Ethernet switches to provide power,
as well as network signals, for compliant devices over existing CAT-5 cable. Implementing devices
that support integrated PoE, such as the HP ProCurve Switch 5400zl and 3500yl series, has several
benefits:
• Lower-cost installations because a single cable provides power along with data connectivity
• No need to modify existing network cabling
• Provides a truly international standard for power distribution
• Enables remote reset and power-off capability
PoE device types
There are two types of devices that are defined for PoE implementations. The first type, called the
powered device (PD), receives power from the second type, called the power sourcing equipment or
PSE. Powered devices include any Ethernet device capable of receiving power through a data port such
as IP telephones, IP cameras, PDAs, and tablet PCs.
Power sourcing equipment, such as HP ProCurve switches with PoE support, must meet IEEE 802.3af
specifications for voltage (47 to 57 volts DC) and wattage (up to 15.4 watts), with further limitations
on the devices that receive power.
HP ProCurve switches that are PoE-enabled support both IEEE 802.3af-compliant devices as well as
some pre-802.3af standard devices.
47
Power delivery options
The 802.3af standard provides two options for providing power over CAT 5 Ethernet cable. They are:
• Unused pairs—This option takes advantage of the fact that 10Base-T and 100Base-TX signals use
only two of the four twisted pairs in the cable. In this option, the pins on pairs 1/2 and 3/6 are used
for data, and the pins on pairs 4/5 and 7/8 are used for power. The 4/5 pair is twisted together to
form the positive supply, and the 7/8 pair is twisted together to form the negative supply.
• Data pairs—This option provides power over pairs that also provide data and is necessary because
1000Base-T signals use all four pairs. In this option, either the 1/2 pair or the 3/6 pair can form the
positive supply.
The 802.3af standard requires power sourcing equipment (PSE) to choose between the options. It is not
possible to mix and match or to use all pairs for power transmission. HP ProCurve switches provide
power over the data pairs. However, the standard requires PDs to be able to accept power over either
data pairs or unused pairs.
PoE negotiation
In most networks, PSE will be connected to some devices that support PoE and some that do not.
Consequently, in order to prevent damage to non-PoE devices, the 802.3af specification includes a
negotiation mechanism between PSEs and the stations connected to them. Under the specification,
PSEs apply a slight voltage on the power-delivery pairs. If there is a valid PD on the cable, it will
present a resistance and a capacitance.
Typically, this discovery process requires approximately 500 milliseconds. The PSE will apply the full
wattage if it discovers a PD, but the flow is current-limited to prevent damage to cable and equipment
under fault conditions.
After discovery, a PD must draw a minimum current for the power flow to remain active. If, for
example, the PD is unplugged, the PSE will discontinue power supply over the cable. The discovery
process will be repeated when the PD is returned to service.
The HP ProCurve switches described in this document that are PoE enabled are:
• HP ProCurve Switch 5406zl—supports up to 144 PoE ports
• HP ProCurve Switch 5412zl—supports up to 288 PoE ports
• HP ProCurve Switch 3500yl-24G-PWR—supports up to 24 PoE ports
• HP ProCurve Switch 3500yl-48G-PWR—supports up to 48 PoE ports
Additional PoE power—external supplies
The HP ProCurve 620 Redundant/External Power Supply can be used with up to two 3500yl Switches
as an external supply providing an extra 398 W of PoE power for each switch. This extra power can be
used to provide full PoE power redundancy at 15.4 W for all ports for the 3500yl-24G-PWR. It can
also be used to provide full 15.4 W to all 48 ports on the 3500yl-48G-PWR, or full PoE power
redundancy at 15.4 W for 24 ports on the 48-port switch.
The HP ProCurve Switch zl Power Supply Shelf provides a 3U-high enclosure to hold up to two extra
zl switch power supplies to provide additional PoE power to zl switches beyond the PoE power
available through the switch’s internal power supplies alone. These extra supplies can also be used to
provide PoE power redundancy beyond what is possible with switch internal supplies. Large Switch zl
VoIP installations are ideal environments for the HP ProCurve Switch zl Power Supply Shelf.
48
Support for pre-802.3af standard powered devices
The HP ProCurve Switch 5400zl and 3500yl series also support a number of pre-802.3af standard
powered devices. These include:
• Cisco 7902G, 7905G, 7912G, 7940G, 7960G IP Phones
• Cisco Aironet 350, 1100, 1200, 1230AG Access Points
The Cisco pre-802.3af standard IP phones require the use of a straight-through cable for connectivity
to the PSE. These IP phones are dependent on the polarity of the DC voltage (a violation of the IEEE
802.3af standard) and will not work properly if the Data Pairs (wires 1 and 2, and 3 and 6) are crossed
over anywhere in the cable plant between the IP phone and power sourcing equipment.
Appendix D: PIM Sparse Mode
In Protocol Independent Multicast-Sparse Mode (PIM-SM), the assumption is that there are no hosts
that want the multicast traffic unless they specifically ask for it. In contrast, PIM Dense Mode (PIMDM) assumes downstream router membership unless it receives an explicit prune message. PIM-SM is
appropriate for wide-scale deployment for both densely and sparsely populated groups and is the
optimal choice for all production networks regardless of size and membership density.
The operation of PIM-SM centers on the use of a shared tree, with a router functioning as a rendezvous
point (RP), the root of the tree. A shared tree prevents each router from maintaining source and group
state information for every multicast source. Regardless of the number or location of multicast
receivers, multicast senders register with the RP and send a single copy of multicast data through it to
the registered receivers. Also, regardless of the location or number of sources, group members register
to receive data and always receive it through the RP.
49
In order to receive a multicast stream, routers explicitly join the stream by sending join messages to the
RP. This join message is analogous to a unicast router following a default route to a destination.
Effectively, the function of the RP is a place for multicast sources and receivers to meet.
PIM-SM is extremely memory and CPU efficient. Since the only thing that most routers need to know
is how to reach the RP, memory requirements are greatly reduced. There are several methods that can
be used by routers in a PIM-SM domain to learn where to find the RP. Probably the simplest
mechanism is statically configuring all routers to reach the RP. However, if the routers are statically
configured to an RP and the RP fails, then the multicast network is no longer functional.
Alternatively, the RP can be learned dynamically through the PIM-SM bootstrap mechanism. Since
this bootstrap mechanism is dynamic, it allows for network changes and redundancy. The PIM-SM
bootstrap mechanism is generally the recommended approach for simplicity and redundancy.
Appendix E: LLDP-MED
IEEE 802.1AB Link Layer Discovery Protocol (LLDP) provides a standards-based method that
enables devices such as HP ProCurve switches to advertise themselves to adjacent devices and to learn
about adjacent LLDP devices. An LLDP packet transmitted by a HP ProCurve switch contains data
about the switch and port. The switch advertises itself to adjacent (neighbor) devices by transmitting
LLDP data packets out all ports on which outbound LLDP is enabled, and reading LLDP
advertisements from neighbor devices on ports that are inbound LLDP-enabled. An LLDP-enabled
port receiving LLDP packets inbound from neighbor devices stores the packet data in a neighbor
database (MIB).
LLDP provides the base capabilities for network devices, but was not considered sufficient for IP
telephony devices. As a result, in 2004, an initiative by Mitel, HP ProCurve, Avaya, and Enterasys was
undertaken to enhance LLDP so that it could better support IP telephony devices. The development of
LLDP-Medium Endpoint Discovery (LLDP-MED) (ANSI/TIA-1057/D6) extended the LLDP standard
to support advanced features on the network edge for VoIP endpoint devices with specialized
capabilities and LLDP-MED standards-based functionality. The extensions to LLDP include the
specification of additional TLV (type, length, and value) entries specifically for VoIP management.
LLDP-MED benefits include:
• Plug-and-play provisioning for MED-capable, VoIP endpoint devices
• Simplified, vendor-independent management enabling different IP telephony systems to
interoperate on one network
• Automatic deployment of convergence network policies that include voice VLANs, Layer 2/CoS
priority, and Layer 3/QoS priority
• Configurable endpoint location data to support the Emergency Call Service (ECS) such as
Enhanced 911, 999, and 112
• Detailed VoIP endpoint data inventory readable via SNMP from the switch
• Power over Ethernet (PoE) status and troubleshooting support via SNMP
• Support for IP telephony network troubleshooting of call quality issues via SNMP
50
LLDP-MED endpoint devices are located at the network edge and communicate using the LLDP-MED
framework. Any LLDP-MED endpoint device belongs to one of the following three classes:
• Class 1 (Generic Endpoint Devices): These devices offer the basic LLDP discovery services,
network policy advertisement (VLAN ID, Layer 2/802.1p priority, and Layer 3/DSCP priority), and
PoE management. This class includes such devices as IP call controllers and communication-related
servers.
• Class 2 (Media Endpoint Devices): These devices offer all Class 1 features plus media streaming
capability, and include such devices as voice/media gateways, conference bridges, and media
servers.
• Class 3 (Communication Devices): These devices are typically IP phones or end-user devices that
otherwise support IP media and offer all Class 1 and Class 2 features, plus location identification
and emergency 911 capability, Layer 2 switch support, and device information management.
Appendix F: Virus Throttle security
Virus Throttle is based on the detection of anomalous behavior of network traffic that differs from a
normal activity. Under normal activity, a computer will make fairly few outgoing connections to new
computers, but instead is more likely to regularly connect to the same set of computers. This is in
contrast to the fundamental behavior of a rapidly spreading worm, which will attempt many outgoing
connections to new computers. For example, while computers normally make approximately one
connection per second, the SQL Slammer virus tries to infect more than 800 computers per second.
51
Virus Throttle works by intercepting IP connection requests, that is, connections in which the source
subnet and destination address are different. The Virus Throttle tracks the number of recently made
connections. If a new, intercepted request is to a destination to which a connection was recently made,
the request is processed as normal. If the request is to a destination that has not had a recent
connection, the request is processed only if the number of recent connections is below a pre-set
threshold. The threshold specifies how many connections are to be allowed over a set amount of time,
thereby enforcing a connection rate limit. If the threshold is exceeded, because requests are coming in
at an unusually high rate, it is taken as evidence of a virus. This causes the throttle to stop processing
requests and, instead, to notify the system administrator.
This capability can be applied to most common Layer 4 through 7 session and application protocols,
including TCP connections, UDP packets, SMTP, IMAP, Web Proxy, HTTP, SSL, and DNS—
virtually any protocol where the normal traffic does not look like a virus spreading. For Virus Throttle
to work, IP routing and multiple VLANs with member ports must first be configured.
Note that some protocols, such as NetBIOS and WINS, and some applications such as network
management scanners, notification services, and p2p file sharing are not appropriate for Virus Throttle.
These protocols and applications initiate a broad burst of network traffic that could be misinterpreted
by the Virus Throttle technology as a threat.
On the HP ProCurve Switch 5400zl, 3500yl, and 6200yl series, Virus Throttle is implemented through
connection-rate filtering. When connection-rate filtering is enabled on a port, the inbound routed traffic
is monitored for a high rate of connection requests from any given host on the port. If a host appears to
exhibit the worm-like behavior of attempting to establish a large number of outbound IP connections in
a short period of time, the switch responds one the basis of how connection-rate filtering is configured.
52
Response options
The response behavior of connection-rate filtering can be adjusted by using filtering options. When a
worm-like behavior is detected, the connection-rate filter can respond to the threats on the port in the
following ways:
• Notify only of potential attack: While the apparent attack continues, the switch generates an Event
Log notice identifying the offending host source address (SA) and (if a trap receiver is configured
on the switch) a similar SNMP trap notice.
• Notify and reduce spreading: In this case, the switch temporarily blocks inbound routed traffic
from the offending host source address for a “penalty” period and generates an Event Log notice of
this action and a similar SNMP trap notice if a trap receiver is configured on the switch. When the
penalty period expires, the switch re-evaluates the routed traffic from the host and continues to
block this traffic if the apparent attack continues. During the re-evaluation period, routed traffic
from the host is allowed.
• Block spreading: This option blocks routing of the host’s traffic on the switch. When a block
occurs, the switch generates an Event Log notice and a similar SNMP trap notice if a trap receiver
is configured on the switch. Note that system personnel must explicitly re-enable a host that has
been previously blocked.
Sensitivity
The ability of connection-rate filtering to detect relatively high instances of connection-rate attempts
from a given source can be adjusted by changing the global sensitivity settings. The sensitivity can be
set to low, medium, high, or aggressive as described below:
• Low: sets the connection-rate sensitivity to the lowest possible sensitivity, which allows a mean of
54 routed destinations in less than 0.1 seconds, and a corresponding penalty time for Throttle mode
(if configured) of less than 30 seconds
• Medium: sets the connection-rate sensitivity to allow a mean of 37 routed destinations in less than
1 second, and a corresponding penalty time for Throttle mode (if configured) between 30 and 60
seconds
• High: sets the connection-rate sensitivity to allow a mean of 22 routed destinations in less than 1
second, and a corresponding penalty time for Throttle mode (if configured) between 60 and 90
seconds
• Aggressive: sets the connection-rate sensitivity to the highest possible level, which allows a mean
of 15 routed destinations in less than 1 second, and a corresponding penalty time for Throttle mode
(if configured) between 90 and 120 seconds
Connection-rate ACL
Connection-rate ACLs are used to exclude legitimate high-rate inbound traffic from the connectionrate filtering policy. A connection-rate ACL, consisting of a series of access control entries, creates
exceptions to these per-port policies by creating special rules for individual hosts, groups of hosts, or
entire subnets. Thus, the system administrator can adjust a connection-rate filtering policy to create and
apply an exception to configured filters on the ports in a VLAN.
Appendix G: VRRP
Virtual Router Redundancy Protocol (VRRP) is designed to eliminate the single point of failure
inherent in the static default routed environment. In a VRRP environment, two or more “virtual”
routers cooperate to provide a high-availability capability on a LAN. VRRP specifies an election
protocol that dynamically assigns routing responsibility to one of the virtual routers on a LAN.
A virtual router consists of a set of router interfaces on the same network that share a virtual router
identifier (VRID) and a virtual IP address. One router in the group becomes the VRRP Master and the
other routers are designated as VRRP Backups. The VRRP Master controls the IP addresses associated
with a virtual router.
53
The VRRP Master router periodically sends advertisements to a reserved multicast group address. The
VRRP Backup routers listen for advertisements and one of the backups will assume the Master role, if
necessary. A VRRP router can support many virtual router instances, each with a unique VRID/IP
address combination. The election process provides dynamic failover to one of the remaining VRRP
Backups should the Master become unavailable.
The virtual IP address shared by a group of VRRP routers on a given network segment functions as the
next-hop IP address used by neighboring hosts. The VRRP Master router simply forwards packets that
have been received from hosts using the VRRP Master as the next-hop gateway. The existence of a
VRRP Master and one or more VRRP Backups is transparent to the neighboring hosts.
The advantage gained from using VRRP is a default path with higher availability, but without
requiring configuration of dynamic routing or router discovery protocols on every end host.
VRRP on HP ProCurve switches is interoperable with other routers that support RFC 3768.
VRRP operational aspects include:
• Preempt delay timer to allow other protocols to complete their convergences
• Preemptive mode can be disabled to prevent VRRP router flapping
• Default Advertisement interval of 1 second
• Default Detection time of 3.6 seconds
XRRP support on 5300xl switch
Similar in concept to VRRP, the HP ProCurve XL Router Redundancy Protocol (XRRP) provides the
equivalent mechanism in the HP ProCurve Switch 5300xl series for backup functionality. Like VRRP,
XRRP presents a virtual router to the end node connections whose IP and MAC address can transition
from the master HP ProCurve Switch 5300xl to the backup HP ProCurve Switch 5300xl in the event
the master HP ProCurve Switch 5300xl interface fails.
XRRP does not interoperate with VRRP, but can coexist in a VRRP environment without interference.
54
Appendix H: OSPF Equal Cost Multipath
In Open Shortest Path First (OSPF), if different subnet destinations in a network are reachable through
multiple equal-cost paths, the router chooses a single path for each destination subnet. (A trunk is
considered a path even though a trunk consists of multiple links).
With OSPF Equal Cost Multipath (OSPF-ECMP), routers support optional load-sharing across
redundant paths to the same subnet. All traffic for different hosts in the same subnet may go through a
different next-hop router. Multiple paths are balanced, based on destination IP address.
HP ProCurve’s OSPF-ECMP feature is interoperable with OSPF-ECMP implementations from various
vendors including Cisco, 3Com, and Extreme. The HP ProCurve implementation supports up to four
ECMP paths.
The example shows that there are three equal-cost, next-hop paths from Router A to the destination
subnets with load-sharing across redundant paths. Router A can route packets based on destination IP
address as follows:
Destination IP
Next hop
10.1.1.1
Router C
10.1.1.2
Router B
10.1.2.3
Router B
10.32.1.1

Appendix I: Advanced Classifier-Based QoS
Released with software version K.14, the Advanced Classifier-Based QoS provides:
• A finer granularity than globally configured features for classifying network traffic (IPv4 or IPv6)
into classes that can be used in cross-feature software configurations
• Traffic selection based on multiple match criteria:
– IP source address (IPv4 and IPv6)
– IP destination address (IPv4 and IPv6)
– Layer 2 802.1Q VLAN ID
– Layer 3 IP protocol
– Layer 3 IP precedence bits
– Layer 3 DSCP bits
– Layer 4 UDP/TCP application port (including TCP flags)
– VLAN ID
• Additional policy actions to manage selected traffic, such as rate-limiting and IP precedence
marking
• Configuring service policies for features such as quality of service (QoS) and traffic mirroring
• The application of service policies to specific inbound traffic flows on individual port and VLAN
interfaces (rather than only on switch-wide or port-wide traffic)

Appendix J: Server-to-Switch Distributed Trunking
Distributed Trunking is a link aggregation technique where two or more links across two switches are
aggregated together to form a trunk. This feature overcomes the limitation in IEEE 802.3ad that
specifies all links of a trunk have to be from a single switch. Distributed Trunking improves resiliency
and load balancing in a layer 2 network.
Distributed Trunking (DT) is included in switch software starting with version K.14. In this initial
release, only Server-to-Switch Distributed Trunking is supported. For each downstream server, it sees
the aggregated links as coming from a single switch, which makes any servers that support standard
802.3ad interoperate with Distributed Trunking.
Distributed trunks can be grouped together by configuring two individual DT-LACP trunks with the
common trunk group name. DT ports will be aggregated dynamically after the configuration. The
server/switch should support standard 802.3ad LACP on the links connecting DT switches. It is
assumed LACP on the servers are configured manually on the server with a list of links to be part of
the LACP trunk.
DT offers load balancing of traffic over multiple physical links. From the server to the switch, the
traffic is balanced according to the load-balancing scheme configured on the server NIC. From the
switch to the server, traffic is balanced according to the MAC DA and SA pair.
Two DT switches can be connected via only one Inter-Switch Connection (ISC) and DT ports can be
connected only to servers. Following is the topology supported.
Limitations/Restrictions
•
•
•
•
•
Meshing and Distributed Trunking features are mutually exclusive.
Routing and Distributed Trunking features are mutually exclusive.
IGMP and DHCP snooping, ARP-protect, and STP are not supported on DT trunks.
Q-in-Q in mixed VLAN mode and DT are mutually exclusive.
ISC ports will be part of all VLANs—i.e., they will become members of a VLAN once that VLAN
is configured.
57
• ISC port can be an individual port or a manual LACP trunk, but a dynamic LACP trunk can’t be
configured as an ISC port.
• Maximum of 8 links in a DT trunk across two switches is supported with a maximum of 4 links per
DT switch
• The current limitation of 60 manual trunks in a switch will now include DT manual trunks too.
• One ISC is supported per switch for a maximum of 60 DT trunks supported in the switch.
• Spanning Tree Protocol is disabled (i.e., PDUs are filtered) on DT ports.
An example of upstream traffic forwarding is as follows
Assuming the uplink connected to Switch B is blocked by STP and only an uplink in Switch A is
active. Server 1 sent traffic with load-balance across its 802.3ad LACP links. If the receiving switch is
Switch A, which learns the destination MAC from any of the upstream links, it will forward the unicast
frames to destination directly via its upstream link. If Switch B receives the unicast frame from the
server and it learns DA (destination address) MAC from Switch A, Switch B will forward the frames
to Switch A, and in turn Switch A forwards the frames to the destination via its upstream link. Thus,
unicast frames are always forwarded by only one of the DT switches.
