The following is an example of how to create an LACP port-channel made up of two ports that will work with an EMC VNX 5300 SAN.
interface GigabitEthernet1/0/14
description san-lacp-1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 2 mode active
end
interface GigabitEthernet1/0/15
description san-lacp-2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 2 mode active
end
interface Port-channel1
description san-lacp
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
end
The channel group mode must be “active”.
After creating the port-channel in the switch and configuring LACP on the SAN, you must “shutdown” and then “no shutdown” the port-channel. This forces the SAN data mover ports to reconnect with the proper LACP values.
