Configuring Link Aggregation Control Protocol 1:1 Redundancy Note • LACP 1:1 redundancy must be enabled at both ends of the LACP EtherChannel. • For the LACP 1:1 Redundancy feature to work, the lacp max-bundle 1 command must be configured along with the lacp fast-switchover command. • For the LACP 1:1 Hot Standby Dampening feature to work, the lacp max-bundle 1 and lacp fast-switchover commands must be configured before the lacp fast-switchover dampening command is configured. To configure LACP 1:1 redundancy, perform this procedure: Procedure Configuring EtherChannels Configuring Link Aggregation Control Protocol 1:1 Redundancy Command or Action Purpose Step 5 end Example:
Device(config-if)# end Returns to privileged EXEC mode. Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password, if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Step 3 interface port-channel group number _ Example: Device(config)# interface port-channel 40 Selects an LACP port channel interface and enters interface configuration mode. Step 4 lacp fast-switchover Example: Device(config-if)# lacp fast-switchover Enables the LACP 1:1 Redundancy feature on the EtherChannel. Step 5 lacp max-bundle 1 Example:
Device(config-if)# lacp max-bundle 1 Sets the maximum number of active member ports to be one. The only value that is supported with LACP 1:1 redundancy is 1. Configuring EtherChannels 26
