Monitoring And Maintaining Tunneling Status - Cisco WS-CBS3032-DEL Software Configuration Manual

Monitoring and Maintaining Tunneling Status

This example shows how to configure the customer switch at Site 1. Fast Ethernet interfaces 1, 2, 3, and 4
are set for IEEE 802.1Q trunking, UDLD is enabled, EtherChannel group 1 is enabled, and the port
channel is shut down and then enabled to activate the EtherChannel configuration.
