Command Function
Dynamic Configuration Commands
lacp
This command enables 802.3ad
Link Aggregation Control Protocol
(LACP) for the current interface.
Use the no form to disable it.
Syntax:
[no] lacp
Default Setting: Disabled
Command Mode: Interface Configuration (Ethernet)
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 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
