Prior to Cisco Release IOS XE 3.5.0E and IOS 15.2(1)SG, when you tried to add a port to an
EtherChannel from different chassis of the VSS system, an error message displayed:
Switch(config)# int gi2/3/26
Switch(config-if)# no switchport
Switch(config-if)# channel-group 50 mode on
Switch(config-if)#
Switch(config)# int gi1/1/48
Switch(config-if)# no switchport
Switch(config-if)# channel-group 50 mode on
Layer 3 MEC is not supported: GigabitEthernet1/1/48 on switch 1 cannot be part of
port-channel 50 with members on switch 2.
Command rejected: conflicts with Unsupported Layer 3 MEC
