show top
Use the show top command to start the TopN process.

•
•
•
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.
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 completely displays. 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 600 background03/09/2000,14:05:38:MGMT-5: TopN report 2 started by telnet/172.20.22.7/.Console>03/09/2000,14:15:38:MGMT-5: TopN report 2 available.This example shows how to start the TopN process without the background option:

Use the show trunk command to display trunking information for the switch.
show trunk [mod[/port]] [detail]
Syntax Description
mod
(Optional) Number of the module.
port
(Optional) Number of the port.
detail
(Optional) Keyword to show detailed information about the specified trunk port.
Defaults
This command has no default setting.
Command Types
Switch command.
Command Modes
Normal.
Usage Guidelines
Entering the show trunk command without specifying a module or port number displays only the actively trunking ports. To display the trunking configuration for a port that is not actively trunking, specify the module and port number of the port you want to display.Entering the show trunk command displays untagged traffic received over the dot1q trunk. For ISL trunks, packets are tagged on all VLANs (including native VLANs).
In the show trunk detail command output, the Peer-Port field displays either the module and port number of the peer connection, or multiple or unknown. Multiple is displayed if connected to shared media, and unknown is displayed if DTP is not running on the other side.
If you enter the show trunk command on a trunk where a VTP domain mismatch exists, an asterisk is displayed after the trunk status and the following:
* - indicates vtp domain mismatch.
In the show trunk command output, the ports and VLANs listed in the spanning tree forward state and not pruned fields are the same regardless of whether or not VTP or GVRP is running.
