Chapter 28 Configuring EtherChannels
Configuring EtherChannels
Beginning in privileged EXEC mode, follow these steps to configure the LACP port priority. This
procedure is optional.
To return the LACP port priority to the default value, use the no lacp port-priority interface
configuration command.
EtherChannels and Ethernet Flow Points (EFPs)
For an LACP or PAgP port to peer with a neighbor on a port that has an Ethernet Virtual Connection
(EVC) EFP service instance configured, you need to enter the l2 protocol peer lacp or l2 protocol peer
lacp service-instance configuration command on the service instance. See the “Configuring Ethernet
Virtual Connections (EVCs)” chapter for more information on EFPs.
This example shows how to configure Layer 2 protocol LACP peer on a service instance:
Switch (config)# interface gigabitethernet0/1
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport trunk allowed vlan none
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation untagged
Switch (config-if-srv)# l2protocol peer lacp
Switch (config-if-srv)# bridge-domain 10
Switch (config-if-srv)# end
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the port to be configured, and enter interface configuration
mode.
Step 3
lacp port-priority priority Configure the LACP port priority.
For priority, the range is 1 to 65535. The default is 32768. The lower the
value, the more likely that the port will be used for LACP transmission.
Step 4
end Return to privileged EXEC mode.
Step 5
show running-config
or
show lacp [channel-group-number]
internal
Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
