Optimizing Port Usage Through Traffic Control and Port Trunking

Port Trunking

The show trunk command in this example does not include a port list. As a result, the listing shows static trunk group information for all switch ports.

Listing Static LACP and Dynamic LACP Trunk Data. This command lists data for only the LACP-configured ports.

Syntax: show lacp

In the following example, ports 1, 2, and 3 have been previously configured for a static LACP trunk. (For more on “Active”, see table 6-7 on page 6-25.)

Dynamic LACP Standby Links. Dynamic LACP trunking enables you to configure standby links for a trunk by including more than four ports in a dynamic LACP trunk configuration. When four ports (trunk links) are up, the remaining link(s) will be held in standby status. If a trunked link that is “Up” fails, it will be replaced by a standby link, which maintains your intended
