Primary Features and Benefits
Performance and Scalability
Today’s enterprise organizations require
cost-effective, flexible, and secure solutions
for delivering communication services
on a network architecture that can scale
and evolve to meet their ever-changing
needs. The FastIron LS Series meets these
requirements with wire-speed architecture
that delivers high-throughput for a range of
Ethernet endpoints while assuring QoS for
business critical applications.
For cost-effective and rapid scaling at
the network edge, the FastIron LS can be
upgraded to support the Brocade IronStack
technology, which allows stacking up to
eight units that act as a logical chassis. The
FastIron LS IronStack system supports 40Gbps switching capacity between stacked
units providing a high-capacity interconnect
across the stack. FastIron LS IronStack
supports stacking over copper and fiber
cables. This provides for flexible stack
configurations in which stacked units can
be separated by more than several hundred
meters of fiber. The FastIron LS Series
makes it easy to deploy a cost-effective,
high-performance solution today that can be
upgraded to support 10-GbE and stacking as
needed to scale the intelligent edge.
The FastIron LS switches support two types
of single port 10-Gigabit Ethernet pluggable
modules, the FLS-1XGC and the FLS-1XG.
The FLS-1XGC supports a CX4 connector
providing a cost-effective, high performance
10-Gigabit Ethernet solution for inter-switch
or server-to-switch connectivity. The FLS-1XG
supports a small form factor pluggable XFP
transceiver. Supported XFP transceivers
include SR, LR, ER, ZR, and ZRD optics
supporting fiber lengths up to 80 Km.
The Brocade IronStack Solution
Ease of Use: Plug and Play
The FastIron LS series may be ordered
pre-configured with the Brocade IronStack
stacking technology or upgraded in the
field. IronStack is an advanced stacking
technology that supports stacked
configurations in which as many as eight
FastIron GS and/or FastIron LS switches
can be interconnected and maintain the
operational simplicity of a single switch.
An IronStack can be a mix-and-match of
different FastIron GS and FastIron LS switch
models providing for very flexible stack
configurations. Each IronStack enabled
FastIron GS or LS model can support up
to 40Gbps of stacking bandwidth per
unit. IronStack configurations can be
built using 10-GbE CX4 copper or XFPbased fiber connections. When XFP-based
fiber connections are used, an IronStack
configuration can be extended between
racks, floors, and buildings with fiber
lengths up to several hundred meters.
The FastIron LS Series supports the IEEE
802.1AB LLDP and ANSI TIA 1057 LLDPMED standards that enable organizations
to deploy interoperable multi-vendor
solutions. Configuring IP endpoints, such
as VoIP stations can be a complex task
requiring manual and time-consuming
configuration. LLDP and LLDP-MED address
these challenges, providing organizations
with a standard and open method for
configuring, discovering, and managing their
network infrastructure, thereby simplifying
and reducing the cost of operations. For
example, LLDP-MED provides an open
protocol for configuring QoS, security
policies, VLAN assignments, and service
priorities. Additionally, LLDP-MED provides
for the discovery of device location and
asset identity, information that is used for
inventory management and by emergency
response services, such as Enhanced 911
(E911). These sophisticated features make
network services easier to deploy and operate
while enabling new and critical services.
The FastIron LS STK models are preconfigured with two one-port 10-GbE
CX4 modules, expanded CPU memory,
an IronStack license (IronStack PROM)
and software. The CX4 module in the STK
models can be replaced in the field with any
of the optional 10-GbE modules available
for the FastIron LS.
An IronStack system operates as a
single logical chassis (with a single IP
management address) and supports crossmember trunking, mirroring, switching,
static routing, sFlow, multicast snooping and
other switch functions across the stack. An
IronStack has a single configuration file and
supports remote console access from any
stack member. Support for active-standby
controller failover, stack link failover, and
hot insertion and removal of stack members
delivers the resilience that is typical of
higher end modular switches.
The FastIron LS Series supports DHCP
client-based auto-configuration, simplifying
customer deployment and configuration
providing true Plug-and-Play. Enterprises
can use this feature to automate the
IP address and feature configuration of
FastIron LS switches without the presence
of a highly-trained network engineer on-site.
Technicians can simply power up a new
FastIron LS and the unit will automatically
receive an IP address and configuration
from DHCP and TFTP servers. Autoconfiguration provides an intelligent solution
to reduce operating expenses and simplify
network management.
Enterprise-Class Security
Traffic Monitoring and
Lawful Intercept
FastIron LS switches are powered by the
Brocade IronWare operating software,
which offers a rich set of Layer 2 switching
services and Layer 3 routing functionality,
an advanced security suite for network
access control (NAC) and denial of service
protection, and QoS. IronWare embedded
security features include protection against
Denial of Service (DOS) attacks via TCP
SYN, ICMP smurf attack prevention, and
broadcast and multicast packet rate limiting.
The FastIron LS also supports key security
features such as Spanning Tree Root
Guard and BPDU Guard to protect network
spanning tree operation. In non-stacking
configurations, the FastIron LS series offers
additional security features, including
dynamic ARP inspection and DHCP snooping
to protect against address spoofing and manin-the middle attacks.
In response to today’s heightened security
environment, organizations may be
required to set up traffic intercept (lawful
intercept). For example, in the United
States, the Communications Assistance
for Law Enforcement Act (CALEA) requires
that businesses be able to intercept and
replicate data traffic directed to a particular
user, subnet, port, etc. This capability
is particularly essential in networks
implementing IP telephony. The FastIron
LS provides the capability necessary to
support this requirement through ACL-based
Mirroring, MAC Filter-based Mirroring, and
VLAN-based Mirroring. Network managers
can apply a “mirror ACL” on a port to mirror a
traffic stream based on IP source/destination
address, TCP/UDP source/destination ports,
and IP protocols such as ICMP, IGMP, TCP,
and UDP. A MAC filter can be applied on a
port to mirror a traffic stream based on a
source/destination MAC address. VLANBased mirroring is another option for CALEA
compliance. Many enterprises have servicespecific VLANs, such as voice VLANs. With
VLAN mirroring, all traffic on an entire VLAN
within a switch can be mirrored, or specific
VLANs can be transferred to a remote server.
Network Access Control
Network managers can rely on features
such as multi-device and 802.1X
authentication with dynamic policy
assignment to control network access and
perform targeted authorization on a peruser level. FastIron LS switches also support
enhanced MAC policies with the ability to
deny traffic to and from a MAC address on
a per-VLAN basis. This powerful tool allows
network administrators to control access
policies for each endpoint device.
Standards-based NAC enables network
operators to deploy best-of-breed NAC
solutions for authenticating network users
and validating the security posture of a
connecting device. Support for policycontrolled MAC-based VLANs provides
additional control of network access,
allowing for policy-controlled assignments of
devices to Layer 2 VLANs.
Threat Detection and Mitigation
Support for embedded, hardware-based
sFlow traffic sampling extends the Brocade
IronShield 360 security shield to the
network edge. This unique and powerful
closed loop threat mitigation solution
uses best-of-breed intrusion detection
systems to inspect sFlow traffic samples
for possible network attacks. In response
to a detected attack, IronView® Network
Manager (INM) can apply a security policy
to the compromised port. This automated
threat detection and mitigation stops
network attacks in real time, without
human intervention. This advanced security
capability provides a network-wide security
umbrella without the added complexity and
cost of ancillary sensors.
Advanced Multicast Features
FastIron LS switches support a rich set
of Layer 2 multicast snooping features
that enable advanced multicast services
delivery. Internet Group Management
Protocol (IGMP) snooping for IGMP version
1, 2, and 3 is supported. IGMPv3 sourcebased multicast snooping improves
bandwidth utilization and security for
multicast services.
such as IPv4 static routes, virtual interfaces
(VE), routing between directly connected
subnets, RIPv1/v2 announce, VRRP, DHCP
Relay, and routed interfaces.
To enable multicast service delivery in
IPv6 networks, the FastIron LS supports
Multicast Listener Discovery (MLD) v1 and
v2 snooping - the multicast protocols used
in IPv6 environments.
In non-stacking configurations, the FastIron
LS models support an optional Edge Layer
3 feature set (EPREM)*. These edge Layer
3 features enable dynamic routing via
OSFPv1/v2 and RIPv1/v2 in addition to
the Base Layer 3 features. With FastIron
LS Base Layer 3 and the optional EPREM
upgrade, network managers can deploy
end-to-end Layer 3 networks and deploy the
same routing policies from edge to core,
simplifying network design and operations.
Building Resilient Networks with
Advanced Layer 2 and Layer 3 Protocols
Unified and Secure Element
Software features such as Virtual Switch
Redundancy Protocol (VSRP), the Brocade
Metro Ring Protocol (MRP I and II), Rapid
Spanning Tree Protocol (RSTP), protected
link groups, 802.3ad Link Aggregation, and
trunk groups provide alternate paths for
traffic in the event of a link failure. Subsecond fault detection utilizing Link Fault
Signaling and Remote Fault Notification
ensures rapid fault detection and recovery.
Enhanced Spanning Tree features such as
Root Guard and BPDU Guard prevent rogue
hijacking of spanning tree root and maintain
a contention and loop-free environment,
especially during dynamic network
deployments. Additionally, the FastIron LS
supports Port Loop Detection on edge ports
that do not have spanning tree enabled.
This capability protects the network from
broadcast storms and other anomalies that
can result from Layer 1 or Layer 2 loopbacks
on Ethernet cables or endpoints.
Base Layer 3 functionality enhances the
capability of the FastIron LS IronStack and
standalone models. Base Layer 3 allows
enterprises to use simple Layer 3 features
The Brocade INM provides unified network
management for the FastIron LS Series.
INM greatly simplifies network operations,
provisioning, troubleshooting, and alarm
reporting. INM offers multilevel access
security on the console and a secure
Web management interface that prevents
unauthorized users from accessing or
changing the switch configuration.
INM employs a Java-based network
configuration and management tool that
displays, in graphical detail, network and
application level traffic information. Network
managers can accurately monitor overall
networking operation, zero in on hot spots,
and quickly diagnose and troubleshoot
difficulties before they develop into
widespread network problems.
The FastIron LS Series includes Secure
Shell (SSHv2), Secure Copy, and SNMPv3
to restrict and encrypt management
communications to the system. Additionally,
support for Terminal Access Controller
Access Control System (TACACS/TACACS+)
and RADIUS authentication ensure secure
operator access.
*Available only on the standalone FastIron LS. This feature is not available on the IronStack enabled FastIron LS.
Fault Detection
FastIron LS switches support logical fault
detection through software features such
as Link Fault Signaling (LFS), Remote Fault
Notification (RFN), Protected Link Groups, and
Unidirectional Link Detection (UDLD).
• Link Fault Signaling (LFS) is a physical
layer protocol that ensures bi-directional
communication on a link between two
10-GbE switches, thereby allowing switches
on both sides to disable the link.
• Remote Fault Notification (RFN) enabled
on 1 GB transmit ports notifies the
remote port whenever the fiber cable
is either physically disconnected or has
failed. When this occurs the devices on
both sides of the link disable the link and
turn OFF the associated LEDs.
• Protected Link Groups minimize disruption
to the network by protecting critical
links from loss of data and power. In a
protected link group, one port in the group
acts as the primary or active link, and the
other ports act as secondary or standby
links. The active link carries the traffic.
If the active link goes down, one of the
standby links takes over.
• UDLD monitors a link between two
FastIron LS switches and brings the ports
on both ends of the link down if the link
fails at any point between the two devices.
FastIron LS switches support enhanced
Digital Optical Monitoring of Brocade
XFP optics providing real time detection
resulting in reduced down time. Network
managers can use the enhanced Digital
Optical Monitoring capability to monitor the
health and strength of the transceivers. Key
optic parameters that can be monitored
include TX/RX power, temperature, and bias
current. The switch will generate alarms
when any of these parameters go beyond
the normal range.
In addition, the FastIron LS switches
support stability features such as Port
Flap Dampening, single link LACP, and
Port Loop Detection. Port Flap Dampening
increases the resilience and availability
of the network by limiting the number of
port state transitions on an interface. This
reduces the protocol overhead and network
inefficiencies caused by frequent state
transitions occurring on misbehaving ports.
Single link LACP provides a fast detection
scheme for unidirectional or bi-directional
faults. This standards-based solution
works with other switch vendors. The Port
Loop Detection feature enables network
managers to detect and prevent Layer 1 and
Layer 2 loops without using STP. Enterprises
that do not enable a Layer 2 Protocol, such
as STP to detect physical loops at the edge
can use Port Loop Detection.
