Use the show traffic command to display Traffic and Peak information for each switching bus.
show trafficThis command has no arguments or keywords.
This command has no default setting.
Switch command.
Normal.
This example shows how to display Traffic and Peak information for each switching bus on Catalyst 5500 and Catalyst 5505 switches:
Console> show traffic Switching-Bus Traffic Peak Peak-Time ------------- ------- ---- ------------------------- A 5% 10% Thu Mar 18 1999, 22:45:20 B 4% 15% Fri Mar 19 1999, 09:59:31 C 6% 8% Fri Mar 19 1999, 11:30:13 Console>
Use the show trunk command to display trunking information for the switch.
show trunk [mod_num[/port_num]] [detail]

/port_num | (Optional) Number of the port. |
detail | (Optional) Keyword to show detailed information about the specified trunk port. |
This command has no default setting.
Switch command.

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.
