Introduction

The IntraCore Product Family

The Asanté IntraCore architecture is the basis for a family of switching system products in fixed, stackable and chassis form factors that allow customers to integrate telephony, video and data applications. Initially two systems will be offered that provide high performance, high port count Layer 2 switching.

Additional configurations will be introduced to offer advanced Layer 3 and above routing, traffic classification, advanced QoS, higher bandwidth and port capacity. All systems will be consistent in their operation and management allowing customers to seamlessly deploy any model in their network.

Edge Switches

Providing the first point of connectivity to the network are the Edge Switches.

These connect to an Enterprise switch in the network core and provide aggregation of traffic from desktop computers over high capacity trunks. The initial product introduced in the Edge Switch category is the IntraStack 8000.

The IntraStack 8000 is a stackable, high performance solution for enterprise edge applications. Each stack supports up to 192 10/100Mbps switched

Ethernet connections for cost-effective high-density connectivity in wiring closets. The system can operate as a stand-alone network or be used in combination with IntraChassis 9000 in the backbone.

Enterprise Switches

In the network core, Enterprise Switches are deployed to aggregate traffic from wiring closets and provide high-speed connectivity to network servers. Typically these switches are modular in form factor, and can be easily upgraded or reconfigured. This flexibility provides for customized configurations to meet a wide variety of requirements. The initial product introduced in this category is the IntraChassis 9000.

The IntraChassis 9000

The IntraChassis 9000 is a chassis based modular Gigabit Ethernet enterprise switch designed for either high density wiring closets or as the core of the network backbone. The system can support up to 192 10/100Mbps switched

Ethernet or 16 switched Gigabit Ethernet connections. System modules offer choice in media and connector types to best suit existing wiring infrastructure systems.

(NFPA 70); United States National Electrical Code

❑

❑

Canada—Canadian Electrical Code, Part I, CSA C22.1

Other countries—International Electrotechnical Commission (IEC) 364, Part 1 through Part 7

Important: Take the following precautions when installing the IntraChassis 9000:

Only trained and qualified personnel should be allowed to install or replace this equipment.

This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3

Service Personnel.

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Unplug the power cord before you work on a system that does not have an on/off switch.

Before installing the IntraChassis 9000, unplug the power cord.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Do not touch the power supply when the power cord is connected. Line voltages are present within the power supply when the power cord is connected.

Read the installation instructions before you connect the system to its power source.

This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit.

Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage.

Page 2-2


Installation Guidelines

Lifting the Chassis Safely

The IntraChassis 9000 is not intended to be moved frequently. Before you install the switch, ensure that your site is properly prepared so that you can avoid moving the chassis later to accommodate power sources and network connections.

Two people are required to lift the IntraChassis 9000. Whenever you lift the chassis or any heavy object, follow these guidelines:

❑

Never attempt to lift a chassis by yourself. The size and weight of a chassis requires two people to safely lift and move it without causing injury or damaging the equipment.

❑

Ensure that your footing is solid, and balance the weight of the chassis between your feet.

❑ Lift the IntraChassis 9000 slowly; never move suddenly or twist your body as you lift.

❑ Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

❑ Leave all switch and power modules in place once they are properly installed.

❑ Always disconnect all external cables before lifting or moving the chassis.

Safety With Electricity

The secondary power supply is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. Before removing a redundant power supply, ensure that the other power supply is turned on.

Follow these basic guidelines when working with any electrical equipment:

❑

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

❑

Disconnect all power and external cables before installing or removing a chassis.

❑ Do not work alone when potentially hazardous conditions exist.

❑

Never assume that power has been disconnected from a circuit;

Page 2-3


Installation and Set-up always check.

❑ Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

❑ Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

❑ Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

❑ Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

❑

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

To use the IntraChassis 9000 as a managed switch, it must be configured with an IP address. This can be accomplished in one of two ways:

❑ automatically using BootP (default)

❑ manually via the unit’s Console port

Page 2-13



BootP Configuration

The IntraChassis 9000 is shipped with BootP support. BootP allows the

IntraChassis 9000 to be automatically configured with an IP address when it is connected to the network and is powered on, if your network contains a BootP server configured with available, valid IP addresses. Use the following procedure to set up BootP.

▲ Important: BootP configuration only works if the

IntraChassis 9000 does not have an IP address assigned to it.

1

Make sure your network has a BootP server configured with a valid IP address entry for the IntraChassis 9000.

2

When the IntraChassis 9000 is connected to the network and is powered on, it automatically transmits a BootP request across the network (up to 10 times) until it receives a valid IP address from the BootP server.

3

After an IP address is received, the IntraChassis 9000 can be

managed via in-band access. See Chapter 3, “Basic Configuration” for more information.

To verify that a valid IP address was received, try to ‘ping’ the IntraChassis

9000; if you can access the IntraChassis 9000, it is properly configured with an

IP address.

See “Bootstrap Configuration” in Chapter 3 for more information on using

BootP.

Page 2-14



Connecting To a Console

Use the following procedure to make the cable connection from a terminal to the console port on the Management Engine of the IntraChassis 9000.

1

Using a straight-through RS-232 cable with a 9-pin male

D-subminiature plug at one end, connect a terminal or workstation (PC or Macintosh) running a terminal emulator to the Console port on the front of the IntraChassis

9000.

2

Make sure both units are powered on.

If using a PC with a terminal emulator, make sure it is configured with the following terminal settings:

❑ Baud: 9600

❑ Data Bits: 8

❑ Parity: None

❑ Stop Bits: 1

❑ Flow Control: None

3

Once connected, the Local Management Main Menu appears on the terminal screen.

For further information on setting an IP address for configuration of a terminal, or a PC running a VT100 terminal or emulator (such as HyperTerminal,

ProComm, or ZTerm), see “System IP Configuration” in Chapter 3.

Enabling or Disabling 802.3x Flow Control

Use the following procedure to control traffic and avoid congestion, such as when there is a shortage of buffer resources for the port. Flow control is accomplished by means of standard PAUSE control frames for each port, independent of all others. The port must be configured to operate in Full

Duplex mode. If you enable flow control on a port which is overwhelmed (runlow in the buffer resources), that port will transmit PAUSE frames; the link partner will obey the PAUSE frame. When the low-resource situation is relieved, the port sends out PAUSE frames with zero time value to un-pause the end-station. To enable flow control, first access the Port Configuration menu by typing p in the Configuration menu, then take the following steps.

9000’s MAC Forwarding Table. It also provides options for displaying MAC addresses and IP/MAC binding by individual port or by VLAN.

The MAC Forwarding Table is a table of node addresses that the IntraChassis

9000 automatically builds by “learning,” It performs this task by monitoring the packets that pass through the IntraChassis 9000, checking the source and destination addresses, and then recording the source address information in the table.

The IntraChassis 9000 uses the information in this table to decide whether a frame should be forwarded to a particular destination port or “flooded” to all the ports other than the received port. Each entry consists of the MAC address of the device and an identifier for the port on which it was received.

◆ Note: The MAC address table can hold a maximum of

8,192 entries.

When you type d in the Configuration menu, the Unicast Forwarding Database

Configuration menu appears, as shown in Figure 3-14.

You can display the Forwarding Database MAC address table with or without

IP addresses. Use the following procedure to view the table.

1

Open the Unicast Forwarding Database Configuration

Menu by typing d in the Configuration Menu.

2

Type either a, p, or v , depending on the range of MAC addresses you want to view.

Type a to display the MAC address table with the MAC addresses of all ports on the IntraChassis 9000.

Type p to specify a port, then see the MAC addresses for that port only.

Type v to specify a VLAN, then see the MAC addresses for the member ports of that VLAN only.

3

At the prompt which appears, type y to see IP addresses in the display or type n to see the display without IP addresses, then press Return. The selected display appears, as shown

in Figure 3-15.

Page 3-30



◆ Notes: The Age field in the MAC address tables indicates the amount of time remaining before an entry ages out.

The Type field refers to the type of entry for the MAC address of a device; the setting may be static, S (set by management, and will not age out), or dynamic, D (learned by the switch, and will be aged out) or multiple, M (associated with multiple IP addresses, as in the case of a router), or I

(management module’s MAC address).

The Self entry represents the IntraChassis 9000 MAC address and IP address.

The Pri field refers to the priority setting for the port.

Advanced Management

This chapter describes advanced topics for SNMP and RMON management of the IntraChassis 9000, Multicast Traffic Management, and configuration of

Spanning Tree Protocol parameters.

Spanning Tree Protocol

The Spanning Tree Protocol (STP) is a part of the IEEE 802.1D standard that provides for redundancy in a bridged LAN by allowing multiple links between points in the LAN.

Without the use of STP, multiple links in a bridged network will result in bridging loops, which allow excess broadcast traffic which can bring down an entire network.

Overview

The spanning tree protocol reduces a network with multiple, redundant connections to one in which all points are connected (the protocol spans the network), but in which there is only one path between any two points (the paths are branched, as in a tree).

For example, in a large network with multiple paths, the same message will get broadcast over the network through multiple paths, resulting in a great amount of extra network traffic, and possibly, network downtime. This “closed path” or

“bridged loop” among the networks can also start an unending packet-passing process.

▲ Important: To explain STP more effectively, the IntraChassis 9000 is described as a bridge for this section of the manual.

Page 5-1



How It Works

All bridges on the network communicate with each other using special packets called Bridge Protocol Data Units (BPDUs). The information exchanged in the

BPDUs enables bridges on the network to:

❑ Elect a single bridge to be the Root Bridge.

❑ Calculate the shortest path from each bridge to the root.

❑ Select a Designated Bridge on each segment which lies closest to the root, and will forward traffic to the root.

❑ Select a port on each bridge to forward traffic to the root.

❑

Select the ports on each bridge which will forward traffic, and place the redundant ports in blocking state.

Enabling and Disabling STP

The IntraChassis 9000 is shipped with Spanning Tree enabled on all ports. It can be manually enabled or disabled following the instructions below

To enable or disable STP on your IntraChassis 9000, use the following procedure.

1

Type c to open the Configuration Menu.

2

Open the Spanning Tree Configuration Menu by typing s

in the Configuration Menu. See Figure 5-1.

3

Type t to toggle STP to enabled or disabled.

4

If you select disabled, you are prompted to confirm the change.

The STP status is changed. The status is displayed near the top of the Spanning Tree Configuration menu.

Spanning Tree Parameters

The operation of the Spanning Tree Algorithm is governed by several parameters. You should only attempt to set these parameters if you have experience with the 802.1D specification.

Bridge Priority

Setting the Bridge Priority to a low value will make it more likely that the current bridge will become the root bridge. If the current bridge is located physically near the center of your network, you may wish to decrease the Bridge

Priority from its default value of 0x8000. If the current bridge is near the edge of your network, it is best to leave the value of the Bridge Priority at its default.

Hello Time

This is the time period between BPDUs transmitted by each bridge.

Maximum Age

Each bridge should receive regular configuration BPDUs from the direction of the root bridge. If the Maximum Age timer expires before the bridge receives

Page 5-3


Advanced Management another BPDU, it assumes that a change in the topology has occurred and begins recalculating the spanning tree.

Forward Delay

The Forward Delay parameter regulates the delay before each port begins transmitting traffic after a recalculation of the spanning tree. If a port begins forwarding traffic too soon, the network can be adversely affected. The permitted range of the Forward Delay is 4 to 30 seconds.

◆ Note: The Hello Time, Maximum Age, and Forward Delay are constrained by the following formula:

(Hello Time + 1) <= Maximum Age <= 2 x (Forward Delay -1)

In general, reducing the values of these timers will make the spanning tree react faster in the case of changes in the topology, but may cause temporary loops as the tree stabilizes in a new configuration. Lengthening the timers will make the tree react more slowly to changes in configuration but will make an unintended reconfiguration less likely. All of the bridges in the tree must agree on the values of these timers, so each bridge uses the ones advertised by the root.

Port Priority

If two ports are connected to the same segment, the manager can affect the probability that either one will be chosen for inclusion in the tree by changing this value.

Setting Port Priority and Path Cost

Use the following procedure to set the STP Port Priority and Path Cost values.

The port priority is a Bridge Spanning Tree parameter that ranks each port.

When 2 or more ports have the same path cost, the STP selects the path with the highest priority (lowest numerical value). By changing the priority of a port, you can make it more or less likely to become the root port. The default value is

128, and the range is 0-255.

Port path cost is the Bridge Spanning Tree parameter that assigns a cost factor to the port. The lower the assigned port path cost, the more likely the port is to be accessed. The default value is a result of the equation path cost = 1000/LAN speed (in Mbps)

Thus, for 10Mbps ports, the assigned default port path cost is 100, for

100Mbps ports the default port path cost is 10, and for 1000Mbps ports, the assigned default port path cost is 1. The range is 1-65,535.

SNMP and RMON Management

The SNMP (Simple Network Management Protocol) may be used to manage the IntraChassis 9000. The SNMP agent supports database objects that are defined in the following management information bases (MIBs):

❑ MIB II (RFC 1213)

❑ Bridge MIB (RFC 1493)

❑ RMON (RFC 1757) 4 groups - Ethernet Statistics, Ethernet History,

Alarm, and Events (See next section for details)

❑

Private IntraChassis 9000 MIB

Any SNMP-based network management application can be used to manage the

IntraChassis 9000. Refer to your SNMP software manual for information on management of switches.

For details on console-based SNMP settings, see “SNMP Configuration” in

Chapter 3.

RMON Management

Remote Network Monitoring allows the network manager to gather data on the network’s traffic for future retrieval. RMON is an Internet Standard defined in

RFC1757.

Using RMON, a network monitor (also called a probe) listens to traffic on the network and gathers statistics which may be retrieved later by a network management station using the Simple Network Management Protocol (SNMP) as described in the previous section. The four groups of RMON that are supported by the IntraChassis 9000 are described in the following sub-sections.

Page 5-7



Ethernet Statistics Group

This group contains statistics measured on each port of the IntraChassis 9000.

These are cumulative counters which start at zero each time the IntraChassis

9000 is reset. The Statistics Group is automatically implemented by the

IntraChassis 9000.

Ethernet History Group

This group records periodic statistical samples from ports on the IntraChassis

9000 and stores them for later retrieval. A network manager can use the data to analyze how network traffic has varied over a period of time.

Alarm Group

This group takes periodic statistical samples from variables in the IntraChassis

9000 and compares them to previously configured thresholds. If the monitored variable crosses a threshold, an event is generated.

Event Group

This group controls the generation and notification of events from the

IntraChassis 9000. The Alarm and Event groups together allow the network manager to configure RMON so that if a particular statistic such as the number of bad frames goes higher than a certain level, the IntraChassis 9000 will send a trap to its configured trap receivers, notifying the manager of the event. For

information on configuring trap receivers, see “SNMP Configuration” in

Chapter 3.

The IntraChassis 9000 switches provide control of the RMON groups only through SNMP. Please see the documentation for your SNMP management application for information.

For more information about RMON, please see RFC1757, “Remote Network

Monitoring Management Information Base”, available from the FTP site listed in Appendix A.

Security

There are three security options you can use on ports of the IntraChassis 9000.

These are duplicated IP detection/trapping, station movement trapping, and new node trapping.

Page 5-8


Security

You can designate a device as a trap receiver as explained in "Adding or

Updating a Trap Receiver" in the "SNMP Configuration" section of Chapter 3.

This receiver device will get the following information from the specified traps.

Trap

Information shown:

Duplicated IP

MAC addresses of both stations using

IP address; number of port(s) on switch

Station Movement

Station’s MAC address and

IP address (if available); number of port

New Node

Intruder’s MAC address and IP address (if available); number of port

Table 5-1 Security Traps

The following subsections describe each of the three security options in detail.

Duplicated IP Detection/Trap

These two security measures allow you to set up detection and the sending of a trap (alert) for the use of a single IP address by two stations. If you enable

Duplicated IP detection, the switch starts monitoring the broadcast ARP

(Address Resolution Protocol) traffic from all of its ports, to detect duplicated

IP address conditions. If you enable detection and the sending of a trap, then the designated trap receiver will get an alert each time a duplicated IP address is used on the system.

◆ Note: In order to send Duplicated IP traps, Duplicated IP detection must be enabled.

Page 5-9



Station Movement Trap

This security measure ensures that when any end station is moved from one switch port to another, an alert (Station Movement Trap) will be sent to the designated trap receiver. The information displayed in the alert is listed in

Table 5-1. The station movement is detected when the station’s MAC address

(already learned by the switch) appears on a different switchboard.

New Node Detection Trap

This security measure ensures that when any new device is connected to the secured port, an alert (New Node Detection Trap) will be sent to the designated

trap receiver. The information shown in the alert is listed in Table 5-1. The new

device is detected when it is connected and its MAC address is recognized as one not present in the current table.

Once a device has been connected and has generated traffic on the network, the trap will not be re-sent. If the switch ages out the MAC address of a connected device from its forwarding database, new traffic from that device will result in a

New Node trap being sent. The default age-out time is 300 seconds. You may reduce the number of traps sent by lengthening the age-out time, as explained

in "Setting the MAC Address Age-Out Time" in Chapter 3.

Enabling and Disabling Duplicated-IP Detection

To enable or disable detection of duplicated IP addresses, access the Security

Management menu by typing t in the Configuration menu. Then type d to toggle Duplicated-IP detection from enabled to disabled, or disabled to enabled. By default, Duplicated-IP detection is enabled.

Enabling and Disabling Duplicated-IP Trap

To enable or disable the sending of a trap when a Duplicated-IP is detected, first enable Duplicated-IP detection as explained in the previous section. Then type i in the Security Management menu to toggle Duplicated-IP Trap from enabled to disabled, or disabled to enabled. By default, Duplicated-IP Trap is enabled.

VLAN Management

A virtual LAN, or VLAN, is a logical segmentation/grouping that allows stations/users to communicate as if they were physically connected to a single

LAN, independent of physical configuration of the network. Though a VLAN

Page 5-11


Advanced Management group presents to the user a picture of connection to a single LAN, it is different from a LAN in the sense that it localizes the broadcast, multicast, and flooded traffic to parts of LAN segments, rather than to the whole LAN. In essence, a

VLAN segment/group can be considered the Layer-2 broadcast segment equivalent of a Layer-3 network.

The real need for VLANs in traditional Layer-2 bridges and switches arises from their use of a basic flooding mechanism which results in unnecessary flooding traffic (broadcast, multicast, and unknown destination traffic) that causes clogging and band-width wastage in a LAN. As today’s networks expand rapidly, the Layer-2 flooding problem can become a bottleneck.

The present-day technology provides various means of controlling these flooding traffic problems, which mainly include deployment of Layer-3 devices that provide broadcast firewalls. Other methods include IP multicast control, customized packet filtering, etc. It is evident that these solutions press the requirement for Layer-3 routers. As all of us know, more and more deployment of legacy routers increases the latency of traffic forwarding and eventually degrades network performance. Also, the cost of maintenance increases and configuration becomes more complex with more Layer-3 devices.

In contrast, VLAN technology offers a simple and efficient solution that enhances the network performance, bandwidth utilization, and more importantly, network security, by localizing the broadcast, multicast, and unicast flooding traffic.

Port based VLANs provide one of the many VLAN approaches that solve the problem of unnecessary flooding. They allow ports to be grouped in VLAN segments, so as to limit the transmission of incoming broadcast, multicast, and unknown destination address frames in a VLAN segment to only those ports that are grouped in that segment. This grouping produces selective flooding, rather than flooding to all ports in the system. This, in turn, greatly reduces the unnecessary flooding traffic in a network.

Other VLAN approaches include MAC-based VLANs and policy-based

VLANs. The present version of the IntraChassis 9000 supports port-based

VLANs in compliance with IEEE P802.1Q/Draft 8 standards. The following sections of the chapter describe the concepts and details needed to configure and manage VLANs on Intrachassis switches.

Untagged Frame: Frame either without 802.1Q VLAN Tag header, or with this header and with VID = 0.

VID: VLAN ID in the range of 1…4095.

◆

Note: The terms “groups” and “segments” are both used to represent VLAN segments in the system. They are numbered from 1 to 64. VLAN Groups

The IntraChassis 9000 supports 64 manually configurable VLAN Groups. A

VLAN group is uniquely identified by a 12-bit (1-4095) VLAN ID (VID). No two VLAN Groups can have the same VID if they reside on the same switch.

Each VLAN group has a portmap that specifies the port members of the VLAN and a set of untagged ports, which specifies the port members of the VLAN group that transmit only VLAN untagged frames. The untagged set can be a subset of the portmap, or it can be the same as the portmap, but it cannot have ports that are not part of the portmap. If a port is in the VLAN portmap and not in the VLAN untagged set, then the port transmits tagged frames only. A

VLAN group can be shared with other VLAN groups for MAC address learning purposes.

Port VLAN ID

Port VLAN ID or PVID is used for VLAN classification of incoming untagged frames and has meaning only when a port is configured to receive both untagged and tagged frames. The untagged frames get classified to the VLAN represented by the PVID of the ingress port and the tagged frames get classified to the VLAN represented by the VID carried in the tag header of the received

Page 5-15


Advanced Management frame. Ports should have a non-zero VID associated with them. By default, the

PVID of all ports is 1, in compliance with IEE P802.1Q specifications. The allowed PVID range is 1-4094. The PVID of 4095 is assigned to ports that are

configured to receive only 802.1Q tagged frames. See the “Port Admit Frame

Type” section for details.

Port Admit Frame Type

All ports are set by default to receive both 802.1Q VLAN tagged frames and untagged frames. According to IEEE P802.1Q, a port should be configurable to admit only 802.1Q VLAN tagged frames. Untagged frames are filtered unconditionally on the ports that are set to admit only 802.1Q tagged frames; the source MAC addresses of the incoming untagged frames are not learned either. When a port is set to receive only 802.1Q tagged frames, it’s PVID has no meaning, and is therefore assigned the value of 4095. Incoming tagged frames are classified to the VLAN represented by the VID in the tag header of

the frame. See the “Port Ingress Filtering” section for more information about

forwarding and filtering of received tagged frames.

This feature is helpful in setting up Intra Switch Link (ISL) configuration.

{need more information}

Port Ingress Filtering

This feature controls the learning and filtering behavior of the ports for which there are incoming untagged and tagged frames. If a port’s ingress filtering is disabled, the learning of incoming source addresses and the forwarding of untagged and tagged frames happens in the switch regardless of whether the ingress port is a member of the incoming frame’s VLAN classification or not.

But when ingress filtering is enabled, incoming untagged and tagged frames are filtered unconditionally, as long as the ingress port is not a member of the frame’s VLAN classification. There is also no learning of the source address.

This feature is helpful in setting up Intra Switch Link (ISL) configuration.

VLAN Port Membership and Untagging

Port members can be added to and deleted from a VLAN Group. This operation is mainly useful in defining the configuration discussed in the {cf

IVL/SVL} section. When you add a port member to a VLAN, it is added to the untagged set by default; this means the frames sent out on this port will be untagged. To change the egress frame type, the port has to be deleted from the

Page 5-16


VLAN Management

VLAN untagged set. Deleting a port from the untagged set means that the port is still a member of this VLAN, but it can transmit tagged frames only. Ports can be added to the untagged set of a VLAN group. When added to the untagged set, the port is added to the VLAN’s port member set also. So in essence, a port in a VLAN can transmit either tagged or untagged frames, depending on its association with the VLAN’s untagged set. No port can transmit both tagged and untagged frames on the same VLAN.

MIB Statistics

MIB Object Definitions for Counters

The following MIB objects are those for which counters are displayed in the

Statistics Counters screens shown in both the console and Web interface. The definitions and references are quoted from RFC 1516.

Readable Frames

"This object is the number of frames of valid frame length that have been received on this port. This counter is incremented by one for each frame received on this port whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: IEEE 802.3 Std,

4.4.2.1) and for which the FCSError and CollisionEvent signals are not asserted.

This statistic provides one of the parameters necessary for obtaining the packet error rate. The approximate minimum time for rollover of this counter is 80 hours."

Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aReadableFrames

Readable Octets

"This object is the number of octets contained in valid frames that have been received on this port. This counter is incremented by OctetCount for each frame received on this port which has been determined to be a readable frame

(i.e., including FCS octets but excluding framing bits and dribble bits).

This statistic provides an indicator of the total data transferred. The approximate minimum time for rollover of this counter is 58 minutes."

Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aReadableOctets

FCS Errors

"This counter is incremented by one for each frame received on this port with the FCSError signal asserted and the FramingError and CollisionEvent signals deasserted and whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: 4.4.2.1, IEEE 802.3 Std).

The approximate minimum time for rollover of this counter is 80 hours."

Page B-1


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aFrameCheckSequenceErrors

Alignment Errors

"This counter is incremented by one for each frame received on this port with the FCSError and FramingError signals asserted and CollisionEvent signal deasserted and whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: IEEE 802.3 Std, 4.4.2.1). If rptrMonitorPortAlignmentErrors is incremented then the rptrMonitorPortFCSErrors Counter shall not be incremented for the same frame.


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aAlignmentErrors

Frame Too Longs

"This counter is incremented by one for each frame received on this port whose OctetCount is greater than maxFrameSize (Ref: 4.4.2.1, IEEE 802.3

Std). If rptrMonitorPortFrameTooLongs is incremented then neither the rptrMonitorPortAlignmentErrors nor the rptrMonitorPortFCSErrors counter shall be incremented for the frame.

The approximate minimum time for rollover of this counter is 61 days."

Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aFramesTooLong

Short Events

"This counter is incremented by one for each CarrierEvent on this port with

ActivityDuration less than ShortEventMaxTime. ShortEventMaxTime is greater than 74 bit times and less than 82 bit times. ShortEventMaxTime has tolerances included to provide for circuit losses between a conformance test point at the AUI and the measurement point within the state machine.

Note: shortEvents may indicate externally generated noise hits which will cause the repeater to transmit Runts to its other ports, or propagate a collision

(which may be late) back to the transmitting DTE and damaged frames to the rest of the network.

Implementors may wish to consider selecting the ShortEventMaxTime towards the lower end of the allowed tolerance range to accommodate bit

GLXY9.book Page 3 Thursday, February 17, 2000 3:04 PM losses suffered through physical channel devices not budgeted for within this standard.


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aShortEvents

Runts

"This counter is incremented by one for each CarrierEvent on this port that meets one of the following two conditions. Only one test need be made. a) The ActivityDuration is greater than ShortEventMaxTime and less than

ValidPacketMinTime and the CollisionEvent signal is deasserted. b) The OctetCount is less than 64, the ActivityDuration is greater than

ShortEventMaxTime and the CollisionEvent signal is deasserted.

ValidPacketMinTime is greater than or equal to 552 bit times and less than 565 bit times.

An event whose length is greater than 74 bit times but less than 82 bit times shall increment either the shortEvents counter or the runts counter but not both. A CarrierEvent greater than or equal to 552 bit times but less than 565 bit times may or may not be counted as a runt.

ValidPacketMinTime has tolerances included to provide for circuit losses between a conformance test point at the AUI and the measurement point within the state machine.

Runts usually indicate collision fragments, a normal network event. In certain situations associated with large diameter networks a percentage of collision fragments may exceed ValidPacketMinTime.


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aRunts

Collisions

"This counter is incremented by one for any CarrierEvent signal on any port for which the CollisionEvent signal on this port is also asserted.


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aCollisions

Late Events

"This counter is incremented by one for each CarrierEvent on this port in which the CollIn(X) variable transitions to the value SQE (Ref: 9.6.6.2, IEEE

Page B-3


802.3 Std) while the ActivityDuration is greater than the LateEventThreshold.

Such a CarrierEvent is counted twice, as both a collision and as a lateEvent.

The LateEventThreshold is greater than 480 bit times and less than 565 bit times. LateEventThreshold has tolerances included to permit an implementation to build a single threshold to serve as both the

LateEventThreshold and ValidPacketMinTime threshold.


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aLateEvents

Very Long Events

"This counter is incremented by one for each CarrierEvent on this port whose

ActivityDuration is greater than the MAU Jabber Lockup Protection timer

TW3 (Ref: 9.6.1 & 9.6.5, IEEE 802.3 Std).

Other counters may be incremented as appropriate." Reference: IEEE 802.3

Rptr Mgt, 19.2.6.2, aVeryLongEvents

D.R. Mismatches

"This counter is incremented by one for each frame received on this port that meets all of the following conditions: a) The CollisionEvent signal is not asserted. b) The ActivityDuration is greater than ValidPacketMinTime. c) The frequency (data rate) is detectably mismatched from the local transmit frequency.

The exact degree of mismatch is vendor specific and is to be defined by the vendor for conformance testing.

When this event occurs, other counters whose increment conditions were satisfied may or may not also be incremented, at the implementor's discretion.

Whether or not the repeater was able to maintain data integrity is beyond the scope of this standard."

Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aDataRateMismatches

Auto Partitions

"This counter is incremented by one for each time the repeater has automatically partitioned this port. The conditions that cause port partitioning are specified in the partition state machine in Section 9 [IEEE 802.3 Std]. They are not differentiated here."

Page B-4


Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aAutoPartitions

Total Errors

"The total number of errors which have occurred on this port. This counter is the summation of the values of other error counters (for the same port), namely: rptrMonitorPortFCSErrors, rptrMonitorPortAlignmentErrors, rptrMonitorPortFrameTooLongs, rptrMonitorPortShortEvents, rptrMonitorPortLateEvents, rptrMonitorPortVeryLongEvents, and rptrMonitorPortDataRateMismatches.

This counter is redundant in the sense that it is the summation of information already available through other objects. However, it is included specifically because the regular retrieval of this object as a means of tracking the health of a port provides a considerable optimization of network management traffic over the otherwise necessary retrieval of the summed counters."
