describes the fields in the show tokenring command output.

Table 2-69 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 via 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 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 specify duration of sample (in seconds).
interval	(Optional) Number of seconds for sample. Valid values include 0, 10...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—Ethernet port 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.

Default

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 Type

Switch command.

Command Mode

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/console session, or by entering a clear top [report_num] command from a separate Telnet/console session. The prompt is not printed before the TopN report is displayed completely. Other commands are blocked until the report has displayed.

The tr and fddi port_type options are not supported by the Catalyst 4000 and 2948G series switches.

Examples

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

Console> show top 10 util interval 600 background

09/11/1998,14:05:38:MGMT-5: TopN report 2 started by telnet/172.20.22.7/.

Console> 

09/11/1998,14:15:38:MGMT-5: TopN report 2 available.

This example shows how to start the TopN process without the background option:

Console> show top 10 util interval 600

show top report

Use the show top report command to list all TopN processes and specific TopN report.

show top report [report_num]

Syntax Description

report_num

(Optional) TopN report number for each process.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

If you do not specify report_num, this command lists all the active TopN processes and all the available TopN reports for the switch. Each process is associated with a unique report number. All TopN processes (both with and without background option) are shown in the list.

An asterisk displayed after the pending status field indicates that it is not a background TopN and the results are not saved.
