Optimizing Traffic Flow with Port Controls, Port Trunking, and Filters

Port Trunking

During the Save process, traffic on the ports configured for trunking will be delayed for several seconds. If the Spanning Tree Protocol is enabled, the delay may be up to 30 seconds.

8.Connect the trunked ports on the switch to the corresponding ports on the opposite device. If you previously disabled any of the trunked ports on the switch, enable them now. (See “Viewing Port Status and Configur­ ing Port Parameters” on page 9-2.)

Check the Event Log (“Using the Event Log To Identify Problem Sources” on page C-22)to verify that the trunked ports are operating properly.

Using the CLI To View Port Trunks

You can list the trunk type and group for all ports on the switch or for selected ports. You can also list LACP-only status information for LACP-configured ports.

Listing Static Trunk Type and Group for All Ports or Selected Ports.

Syntax: show trunks [<port-list>]

Omitting the < port-list> parameter results in a static trunk data listing for all LAN ports in the switch. For example, in a switch where ports A4 and A5 belong to Trunk 1 and ports A7 and A8 belong to Trunk 2, you have the options shown in figures 9-9-8and 9-9-9for displaying port data for ports belonging to static trunks.
