During the Save process, traffic on the ports configured for trunking will

the opposite device. If you previously disabled any of the trunked ports
on the switch, enable them now. (See

ports. You can also list LACP-only status information for LACP-configured

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
9-9-8 and 9-9-9 for displaying port data for ports belonging to
static trunks.
