• If the target switch has also enabled LACP on the connected
ports, the trunk will be activated automatically.
• 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.
Example
The following shows LACP enabled on ports 10-11. 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
Trunk 1 has been established.
Console(config)#interface ethernet 1/10
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#interface ethernet 1/11
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#interface ethernet 1/9
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#exit
Console#show interfaces status port-channel 1
