Chapter 1

Introduction

What is in This Chapter

This chapter describes the SPECTRUM Management Module for the

NBR-620. It also provides the model type name assigned to the NBR-620 in

SPECTRUM. The model type name refers to the template used to specify attributes, actions, and associations for device models in SPECTRUM.

NBR-620 Management Module

The SPECTRUM NBR-620 Management Module manages NBR-620 devices using the SNMP network management agent. SPECTRUM bases its management of these devices on the Management Information Bases (MIBs), which come as part of the management module. There are three SPECTRUM model type names for NBR-620 Devices, described as follows:

BRtrCSINBR620 : A Cabletron Systems Six-Port Intelligent Bridging

Routing Module supporting two Bridging Routing Interface Module (BRIM) interfaces and four Ethernet Port Interface Modules (EPIMs).

The other two models, NBR-420 and the NBR-220, use the same model type as the NBR-620, BRtrCSINBR620. The NBR-420 has one BRIM interface and two EPIMs. The NBR-220 has two EPIMs and does not support UPS or

Modems. Once the model type has been added, the device is queried and the appropriate number of ports are displayed.

SPECTRUM and the NBR-620

SPECTRUM and the NBR-620

TheNBR-620 is a multi-port intelligent bridging module.The NBR-620 has two Bridging/Routing Interface Module (BRIM) slots. A BRIM performs the same bridging functions as an EPIM: it transfers packets between different channels. However, unlike EPIMs, BRIMs bridge these packets from one transmission type to another (e.g., Ethernet to FDDI network backbones, etc.).

Possible BRIMs are as follows:

¥ BRIM-F6: FDDI Dual Attached Station (DAS) connection (currently supported)

¥ BRIM-E6: Ethernet module with selectable media connections

¥ BRIM-W6: Wide Area Network connection

¥ BRIM-T6: Token Ring connection

¥ BRIM-A6: Asynchronous Transfer Mode connection

To model this device, create LAN_802_3 models representing each network that the NBR-620 is bridging and connect them to the NBR-620 icon. The software ÒconnectsÓ an ethernet icon to each of the ethernet ports (Channels

A, B, C, and D) and places them in the NBR-620 Device Topology (DevTop)

View. You can then copy these icons into the LAN_802_3 icons to allow

performance statistics to be gathered on each LAN_802_3 subnet. Figure 1-1

shows a possible NBR-620 conÞguration in SPECTRUM.

NOTE

If you are running a previous version of SPECTRUM, the following user interface aspects may differ from those in SPECTRUM version 4.0:

¥Order and names of menu selections

¥ Navigational features (mouse button functionality)

For information about menu selections and navigating within previous versions of SPECTRUM, refer to the S PECTRUM System UserÕs Guide . For more information about menu selections and navigating within SPECTRUM version 4.0, refer to the SPECTRUM Views reference .

Router Redundancy

Router Redundancy

Router Redundancy enables SPECTRUM to contact the device through an alternate port in the event of a primary port failure.

If SPECTRUM is unable to contact the router through the IP address initially assigned to it (Primary Address), the routerÕs icon turns yellow, and

SPECTRUM attempts to reach the router via the ports on the deviceÕs

Preferred Address list, until contact is made. SPECTRUM then uses that IP address to obtain network management information from the router until the

Primary Address becomes available again. When contact is re-established through the Primary Address, the icon turns green.

If SPECTRUM is unable to make contact via any of the Preferred Addresses, the routerÕs icon turns red, denoting that contact has been lost with the actual physical device.

Turning Router Redundancy Off and On

The default status for Router Redundancy is ÒTrueÓ (on). Turn it off and on as follows:

1.

Select Model Information from the Icon Subviews menu.

2.

Click Router Redundancy Information. Select False from the Router

Redundancy button to turn off router redundancy and select True to turn it on.

What is in this Chapter

This chapter describes the types of events and alarms generated by the

NBR-620 and any probable cause messages corresponding to these alarms.

NBR-620 Events and Alarms

Events and alarms originate as generic SNMP traps sent from the physical device. These traps, or unsolicited messages, are translated as SPECTRUM events and displayed in the Event Log. For more information on traps generated by a speciÞc device, refer to RFC 1213, available through the

Internet system. Also refer to the MIB documentation for the speciÞc device.

For each event/alarm listed in this chapter, the following information is provided:

¥ The event code

¥ The event/alarm message

¥ Any probable cause message for the mapped alarm

¥ Any recommended actions

Variable data inserted in a message is indicated by the following brackets: {}

The following table describes the event messages appearing in the Event Log, and any corresponding probable cause messages that may be displayed in the

Enterprise Alarm Manager View for the NBR-620.

Event Message





Port {I 3} in slot {I 1} has failed redundancy polling and has switched to a backup port.

The polled device(s) in the redundant circuit polling list have failed to respond.

The device(s) have failed, been powered down, or a cable fault from the active port to the polled device has occurred. Check the retry count as it may need to be adjusted on a busy network segment.

Normal collision occurrences may occur causing the poll packet to not reach its destination.

CsEvFormat/Event000d010a CsPCause/Prob000d010a


Port {I 3} in slot {I 1} has now become active as the result of a redundancy polling failure.

The polled device has been communicated with via a backup port and the port is now active. The other ports in this redundant circuit are now designated as backup and are turned off to prevent data loops on the network.

CsEvFormat/Event000d010b CsPCause/Prob000d010b

{d Ò%w- %d %m-, %Y - %TÓ} - Redundancy diagnostics of {m} ({t}), indicate that the redundant link for module {I 1}, port {I 3} has failed.

The cable segment connected to the port has a cable fault and should be checked for continuity as soon as possible in the event the other ports in this redundant circuit fail and this port is needed.

CsEvFormat/Event000d010f CsPCause/Prob000d010f

{d Ò%w- %d %m-, %Y - %TÓ} - User deÞned trafÞc threshold - {I 1} packets within {I 3} seconds, exceeded on module {I 5} of {m}

({t}).

The packet rate on this module has exceeded user deÞned limits. The device(s) attached to this module may have an application which requires a large amount of network bandwidth. If the application required a large amount of network bandwidth, then a bridge or router could be used to logically separate various network segments. Use port level thresholds to further troubleshoot to a device level.


{d Ò%w- %d %m-, %Y - %TÓ} -

Error threshold exceeded. An error threshold of {I 1}% good packets in {I 5} seconds, exceeded on module in slot {I 7}.

This threshold will indicate that a malfunctioning device is present on this module or that a cable fault exists. A port level threshold should be set to further troubleshoot to the offending node.

Table 4-1.


Event Message




{d Ò%w- %d %m-, %Y - %TÓ} -

Collision threshold exceeded. Collisions exceeded {I 1}% of good packets in {I 3} seconds on the module in slot {I 5} of {m}

({t}).


Collisions are caused by many nodes contending for the network of cabling faults. Use port level thresholds to further troubleshoot to a device level.


{d Ò%w- %d %m-, %Y - %TÓ} -

TrafÞc threshold, packets per {I 3} seconds, exceeded on port {I 7} on module in slot {I 5} of {m} ({t}).

The device(s) attached to this port may have an application which requires a large amount of network bandwidth. If the application requires a large amount of network bandwidth, then a bridge or router could be used to logically separate various network segments.


{d Ò%w- %d %m-, %Y - %TÓ} -

Error threshold exceeded. An error threshold of {I 1}% good packets in {I 5} seconds, exceeded on port {I 9} on module in slot {I 7} of {m} ({t}).

The device(s) attached to this port could have a hardware failure where it transmits invalid packets or the cable segment attached to this port may have a problem. Check cable for loose connection or continuity problems.


{d Ò%w- %d %m-, %Y - %TÓ} -

Collision threshold exceeded. Collisions exceeded {I 1}% of good packets in {I 3} seconds on port {I 7} on module in slot {I 5} of {m} ({t}).

The device(s) attached to this port may have an adapter card problem which causes them to transmit without regarding network availability or a cable problem may exist. Check adapter card and cable for loose connections, termination problems, or improper pinouts.

Event Message




{d Ò%w- %d %m-, %Y - %TÓ} -

Port type changed. Port {I 3} of module in slot {I 1} has changed types of {m} ({t}).

The number of addresses in the source address table has changed. If more than one address is learned on a port for one aging time period, the port is designated as a trunk port. A port connecting two hubs or a coax segment with multiple taps are examples of trunk ports. If a port has one address in the source address table for two aging time, the port is designated as a station port. An example of a station port would be a twisted pair Òhome runÓ to a PC.


{d Ò%w- %d %m-, %Y - %TÓ} -

Port security violation has occurred on port {I 3} of module in slot {I 1} has changed types of {m} ({t}).


This event is only generated when the hub has port locking enabled. When a hub is locked, the source MAC addresses are learned on each port. When a port detects an attached device has changed its address, the device will note that the new address is not in the source address table.

This will disable and lock the port which then transmits this trap. This trap would be generated if an adapter were replaced or if an intruder attempts to access the network.


{d Ò%w- %d %m-, %Y - %TÓ} -

Port violation reset, port {I 3} of module in slot {I 1} of {m} ({t}).

The network administrator has located the offending device that caused the port violation and has re-enabled the port for use by the original network address for that port.


{d Ò%w- %d %m-, %Y - %TÓ} -

Environment Temperature Warm condition for module in slot {I 1} reported by {m} ({t}).

The module may be defective or a fan has failed in the chassis. Check the alarm log for this device for any fan alarms.

{d Ò%w- %d %m-, %Y - %TÓ} -

TrafÞc threshold, {I 1} packets per {I 3} seconds exceeded on the repeater network

{I 5} of {m} ({t}).

The device(s) attached to this channel may have an application level problem.

The attached devices may be operating properly but the application requires a large amount of network bandwidth. If the application requires a large amount of network bandwidth, then a bridge or router may be used to logically separate various network segments. This trap indicates that module or port level thresholds on this repeater channel are needed to pinpoint high bandwidth users.


{d Ò%w- %d %m-, %Y - %TÓ} -

Error threshold exceeded. An error threshold of, {I 1}% good packets in {I 5} seconds, exceeded on repeater network {I

7} of {m} ({t}).

A user deÞned threshold has been exceeded on this channel. This threshold could indicate that a malfunctioning device is present on this channel or that a cable fault exists. A module or port level threshold should be set to further troubleshoot to the offending node.

Event Message




{d Ò%w- %d %m-, %Y - %TÓ} -

Collision threshold exceeded. Collisions exceeded {I 1}% good packets in {I 3} seconds on repeater network {I 5} of {m}

({t}).


A user deÞned threshold has been exceeded on this channel. This threshold could indicate that a malfunctioning device is present on this channel or that a cable fault exists. Collisions are usually caused by many nodes contending for the network. As trafÞc rates increase, the collision rate usually follows. Thus, if this channel has a high bandwidth utilization, a high collision rate is not unlikely. Use module and port level thresholds to further troubleshoot to a device level.


{d Ò%w- %d %m-, %Y - %TÓ} -

Network port security lock has been {I 1} on repeater network {I 3} on {m} ({t})

The network administrator has changed the status of port locking for this repeater channel. The security feature locks all ports on this repeater channel so that only a valid user already in the source address table can access the network.
