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

Port Trunking

Using a port list specifies, for switch ports in a static trunk group, only the ports you want to view. In this case, the command specifies ports A5 through A7. However, because port A6 is not in a static trunk group, it does not appear in the resulting listing:

Port A5 appears with an example of a name that you can optionally assign using the Friendly Port Names feature. (See “Using Friendly (Optional) Port Names” on page 6-15.)

Port A6 does not appear in this listing because it is not assigned to a static trunk.

Figure 9-8. Example Listing Specific Ports Belonging to Static Trunks

The show trunks [e] < port-list> command in the above example includes a port list, and thus shows trunk group information only for specific ports that have membership in a static trunk. In figure 9-9-9,the command does not include a port list, so the switch lists all ports having static trunk membership.
