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 10-12. 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 1/10
Console(config-if)#lacp
Console(config-if)#interface ethernet 1/11
Console(config-if)#lacp
Console(config-if)#interface ethernet 1/12
Console(config-if)#lacp
Console(config-if)#end
Console#show interfaces status port-channel 1
