COMMAND USAGE
◆ The ports on both ends of an LACP trunk must be configured for full
duplex, either by forced mode or auto-negotiation.
◆ A trunk formed with another switch using LACP will automatically be
assigned the next available port-channel ID.
◆ If the target switch has also enabled LACP on the connected ports, the
trunk will be activated automatically.
◆ If more than eight 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.
EXAMPLE
The following shows LACP enabled on ports 1-3. Because LACP has also
been enabled on the ports at the other end of the links, the show interfaces
status port-channel 1 command shows that Trunk1 has been established.
Console(config)#interface ethernet 1/1
Console(config-if)#lacp
Console(config-if)#interface ethernet 1/2
Console(config-if)#lacp
Console(config-if)#interface ethernet 1/3
Console(config-if)#lacp
Console(config-if)#end
Console#show interfaces status port-channel 1
