◆ Once the remote side of a link has been established, LACP operational settings
are already in use on that side. Configuring LACP settings for the partner only
applies to its administrative state, not its operational state.
Note: Configuring the partner admin-key does not affect remote or local switch
operation. The local switch just records the partner admin-key for user reference.
◆ By default, the actor’s operational key is determined by port's link speed
(1000f - 4, 100f - 3, 10f - 2), and copied to the admin key.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#lacp actor admin-key 120
Console(config-if)#
lacp mode This command configures LACP port mode. Use the no form to restore the default
setting.
Syntax
lacp {actor | partner} mode {active | passive}
no lacp {actor | partner} mode
actor - The local side an aggregate link.
partner - The remote side of an aggregate link.
active - The port will be set the LACP Active mode

Default Setting
active
Command Mode
Interface Configuration (Ethernet)
Command Usage
When a port is controlled by LACP it can be in either Active or Passive mode. In
Active mode the port transmits LACPPDUs periodically to find a partner. In Passive
mode the port will only transmit LACPDUs when responding to a received LACPDU.
For LACP negotiation, one switch should be configured as Active and the other as
Passive.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#lacp actor mode passive
