Interface Configuration (Ethernet)
Command Usage
The ports on both ends of an LACP trunk must be configured for full duplex, and 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 11-13. 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 1/11
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#interface ethernet 1/12
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#interface ethernet 1/13
Console(config-if)#lacp
Console(config-if)#exit
Console(config)#exit
Console#show interfaces status port-channel 1
