There are three versions of SNMP:

•Version 1 (SNMPv1)—This is the initial implementation of SNMP. Refer to Request for Comments (RFC) 1157 for a full description of functionality.

•Version 2 (SNMPv2c)—The second release of SNMP, described in RFC 1902, has additions and enhancements to data types, counter size, and protocol operations.

•Version 3 (SNMPv3)—This is the most recent version of SNMP and is fully described in RFC 2571, RFC 2572, RFC 2573, RFC 2574, and RFC 2575. SNMPv3 has significant enhancements to administration and security.

The SNMP functionality on the Catalyst enterprise LAN switches for SNMP v1 and SNMP v2c remains intact; however, the functionality has greatly expanded for SNMPv3. Refer to the "Configuring SNMP" chapter of the Catalyst 5000 Family Software Configuration Guide for more information on SNMPv3.

The read-only keyword is supported for security model v3 only.

There are three versions of SNMP:

•Version 1 (SNMPv1)—This is the initial implementation of SNMP. Refer to Request for Comments (RFC) 1157 for a full description of functionality.

•Version 2 (SNMPv2c)—The second release of SNMP, described in RFC 1902, has additions and enhancements to data types, counter size, and protocol operations.

•Version 3 (SNMPv3)—This is the most recent version of SNMP and is fully described in RFC 2571, RFC 2572, RFC 2573, RFC 2574, and RFC 2575. SNMPv3 has significant enhancements to administration and security.

The SNMP functionality on the Catalyst enterprise LAN switches for SNMP v1 and SNMP v2c remains intact; however, the functionality has greatly expanded for SNMPv3. Refer to the "Configuring SNMP" chapter of the Catalyst 5000 Family Software Configuration Guide for more information on SNMPv3.

You can use this command to troubleshoot slow network convergence due to skewing. Skewing occurs when spanning tree timers lapse, expected BPDUs are not received, and spanning tree detects topology changes. The difference between the expected result and the BPDUs actually received is a skew. The skew causes BPDUs to reflood the network to keep the spanning tree topology database up to date.

he command works on a per-port basis. When you enable the feature on a port, a logical port is blocked on a per-VLAN basis. This means that you can specify a port (or a list of ports) and specify a VLAN, but you cannot specify both.

If a port in the list is in the root-inconsistent state, then the port automatically goes into the listening state again.

Examples

This example shows how to display spanning tree guard information for a specific VLAN:

Console> show spantree guard 1004

Port Vlan Port-State           Guard type

---- ---- -------------------  ------------

1/1  1004  root-inconsistent    root

1/2  1004  not-connected        none

2/1  1004  loop-inconsistent    loop

2/2  1004  forwarding           loop

.

Usage Guidelines

The show tech-support command output is continuous; it does not display one screen at a time. To interrupt the output, press Ctrl-C.

The show tech-support command may time out if the configuration file output takes longer to display than the configured session timeout time. If this happens, enter a set logout timeout value of 0 to disable automatic disconnection of idle sessions or enter a longer timeout value.

If you specify the config keyword, the show tech-support command displays the output of these commands:

•show config

•show flash

•show log

•show microcode

•show module

•show port

•show spantree active

•show system

Table 2-83 describes the fields in the show tokenring command output.

Table 2-83 show tokenring Command Output Fields 

Field	Description
Ports	Module and port number.
Crf/Brf	TrCRF to which a port is assigned and the parent BRF associated with the CRF.
Ring	Logical ring number (in hexadecimal format) assigned to the TrCRF. Possible values are auto and 01 through FFF.
Port-Mode	Operation mode of the port. Possible values are auto, fdxcport, fdxstation, hdxcport, hdxstation, passive, or riro. Only FDX and HDX modes are detected automatically. The operation mode of riro applies to fiber ports only.
Early-Token	Status of whether the port is enabled for early token release. Possible values are yes and no; the default is yes. Early token release is valid for 16-Mbps media only. If the early token release is enabled and the media speed is 4 Mbps, the switch forces early token release to be disabled.
AC-bits	Status of whether the AC-bits should be set unconditionally on repeated source-routed LLC frames. These include source-routed frames with RIF length greater than 2 and all Spanning Tree Explorer and All-Routes Explorer frames; the default is no. If you set this parameter to no, the setting of these bits is based on whether the frame was actually forwarded.
Prior-Thresh	Highest Token Ring frame priority in the Frame Control field of the frame that the switch should place in the low-priority transmit queue. Possible values are 0 through 7; the default is 3.
Min-Xmit	Minimum reservation priority used when requesting a token on a busy ring. Possible values are 0 through 6; the default is 4.
MAC-Address	MAC address of the port.
Cfg-Loss-Thresh	Value used to control the number of configuration losses that can occur within the configuration loss sampling interval. Configuration loss occurs when a port completes a connection, allows data traffic to flow, and subsequently closes. When the threshold is exceeded, the port is disabled and you must enable it through with this panel or an SNMP manager. Possible values are 1 through 100; the default is 8.
Cft-Loss-Intvl	Sampling period (in minutes) for measuring the number of configuration losses. Possible values are 1 through 60; the default is 1.
Cfg-Loss-Count	Number of Token Ring configuration loss events after the port has completed the join process and then lost communication.
Cfg-Loss-Reason	Error code of the latest configuration loss event. Possible values are None, Wire Fault, Lobe Test Fail, TKP Frame Error, Heart Beat Fail, TXI New Station, TXI Prot Error, Speed Error, or Remove Received.

show top

Use the show top command to start the TopN process.

show top [N] [metric] [interval interval] [port_type] [background]

Syntax Description

N	(Optional) Number of ports displayed. Valid values are from 1 to a maximum number of physical ports.
metric	(Optional) Port statistic to sort on. Valid values are as follows: util—utilization bytes—in/out bytes pkts—in/out packets bcst—in/out broadcast packets mcst—in/out multicast packets errors—in errors overflow—buffer overflow
interval	(Optional) Keyword to display duration of sample (in seconds).
interval	(Optional) Number of seconds for sample. Valid values include 0 and from 10 to 999 seconds. If the value is 0, the N topmost ports by absolute counter values are displayed.
port_type	(Optional) Type of switch ports to use for report. Valid values are as follows: all—All port types are used eth—All Ethernet port types are used 10e—10Mbps Ethernet ports types are used fe—Fast Ethernet port types are used ge—Gigabit Ethernet port types are used tr—Token Ring port types are used fddi—FDDI port types are used
background	(Optional) Keyword to specify the TopN report not to print to the screen when the task is done. Instead, send a notification out when the reports are ready.

Defaults

The defaults are as follows:

•Number of ports displayed is 20.

•Port statistics to report on is util.

•Sample duration is 30 seconds.

•Switch port types is all.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

You can terminate TopN processes with the background option specified only by using the clear top [report_num] command. You cannot terminate TopN processes by pressing Ctrl-C.

TopN reports with the background option specified are not displayed on the screen unless you enter a show top report [report_num] command.

If you do not specify the background option, the output TopN results are dumped to the screen when the task is done, and the results are printed one time only and are not saved.

You can terminate TopN processes (without the background option) by pressing Ctrl-C in the same Telnet or console session, or by entering a clear top [report_num] command from a separate Telnet or console session. The prompt is not printed before the TopN report is displayed completely. Other commands are blocked until the report has displayed.

Examples

This example shows how to start the TopN process with the background option:

Console> show top 10 util interval 10 background
