This example shows how to configure the customer switch at Site 1. Gigabit Ethernet interfaces 1/1, 1/2,
1/3, and 1/4 are set for 802.1Q trunking, UDLD is enabled, EtherChannel group 1 is enabled, and the
port channel is shut down and then enabled to activate EtherChannel configuration. See also Figure 30-8.
