show traffic

Use the show traffic command to display Traffic and Peak information for each switching bus.

show traffic
Syntax Description

This command has no arguments or keywords.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Example

This example shows how to display Traffic and Peak information for each switching bus on Catalyst 5500 and Catalyst 5505 switches:

Console> show traffic

show trunk

Use the show trunk command to display trunking information for the switch.

show trunk [mod_num[/port_num]] [detail]
Syntax Description

mod_num

(Optional) Number of the module.

/port_num

(Optional) Number of the port.

detail

(Optional) Keyword to show detailed information about the specified trunk port.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

Entering the show trunk command without specifying a module or port number displays 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 RSM port displays as a port that is always trunking, with allowed and active VLANs for each VLAN configured on the RSM.

The Catalyst 2948G is a fixed configuration switch. All ports are located on module 2; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.

Examples

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