Static LAG Configuration
SW1
 
SW1#configure terminal
Enter configure mode.
SW1(config)# bridge 1 protocol mstp
Configure bridge 1 as MSTP bridge
SW1(config)#lacp system-priority 20000
Set the system priority of this switch. This priority is used for determining the system that is responsible for resolving conflicts in the choice of aggregation groups. A lower numerical value has a higher priority.
SW1(config)#interface sa10
Enter into port channel interface sa10.
SW1(config-if)#switchport
Configure po10 as a layer 2 port.
SW1(config-if)#bridge-group 1
Associate bridge to an interface.
SW1(config-if)#switchport mode trunk
Configure port as a trunk.
SW1(config-if)#switchport trunk allowed vlan all
Allow all the VLANs on the po10 interface.
SW1(config-if)#exit
Exit interface mode.
SW1(config)#interface eth1
Enter interface mode.
SW1(config-if)#static-channel-group 10
Add this interface to channel group 10 and enable link aggregation so that it can be selected for aggregation by the local system.
SW1(config-if)#exit
Exit interface mode.
SW1(config)#interface eth2
Enter interface mode.
SW1(config-if)#static-channel-group 10
Add this interface to channel group 10 and enable link aggregation so that it can be selected for aggregation by the local system.
SW1(config-if)#exit
Exit interface mode.
SW1(config)#interface eth3
Enter interface mode.
