PORT TRUNKING COMMANDS

trunk will be activated.

•If more than four ports attached to the same target switch have LACP enabled, the additional ports will be placed in standby mode, and will only be enabled if one of the active links fails.

•STP, VLAN, and IGMP settings can only be made for the entire trunk via the specified port-channel.

•A trunk formed with another switch using LACP will automatically be assigned the next available port-channel id.

Example

The following shows LACP enabled on ports 1 and 2. Because LACP has also been enabled on the ports at the other end of the links, the show interfaces status port-channel 2 command shows that Trunk 2 has been established.

Console(config)#interface ethernet 1/1

Console(config-if)#lacp

Console(config-if)#exit

Console(config)#interface ethernet 1/2

Console(config-if)#lacp

Console(config-if)#exit

Console(config)#exit

Console#show interfaces status port-channel 1
