show top
To start the TopN process, use the show top command.
show top [N] [metric] [interval interval] [port_type] [background]
Syntax Description

The defaults are as follows:
•
Number of ports displayed is 20.
•
•
•
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 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 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:

show top report
To list all TopN processes and specific TopN reports, use the show top report command.
show top report [report_num]
Syntax Description
Defaults
This command has no default settings.
Command Types
Switch command.
Command Modes
Normal.
Usage Guidelines
If you do not specify the report_num value, 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 a 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.
Examples
This example shows how to display all the active TopN processes and all the available TopN reports for the switch:

show trunk
To display trunking information for the switch, use the show trunk command.
show trunk [mod[/port]] [detail] [extended-range]
Syntax Description
Defaults
This command has no default settings.
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. The MSM port displays as a port that is always trunking, with allowed and active VLANs for each VLAN configured on the MSM.
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 this message appears:
* - 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.

This example shows how to display trunking information for the switch:
