Configuring Other Features on EFPs
Switch (config-if-srv)# exit
Switch (config-if)# service instance 2 Ethernet
Switch (config-if-srv)# encapsulation dot1q 15 second-dot1q 30
Switch (config-if-srv)# bridge-domain 2
Example 4
The switchport pops the outermost VLAN implicitly, and service instance 2 needs to parse the second
and third VLANs. In this case, the service instance 2 configuration is rejected because it needs to match
on the third VLAN of the packet bridged from the switchport to the second-dot1q encapsulation of
service instance 2.
Switch (config)# interface gigabitethernet 0/1
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport allowed vlan 2
Switch (config)# interface gigabitethernet 0/2
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport allowed vlan none
Switch (config-if)# service instance 2 Ethernet
Switch (config-if-srv)# encapsulation dot1q 20 second-dot1q 30
Switch (config-if-srv)# bridge-domain 2
Note
In all of these examples, if service instance 2 was configured before service instance 1, the configuration
for service instance 1 would be rejected.

EFPs and EtherChannels
You can configure EFP service instances on EtherChannel port channels, but EtherChannels are not
supported on ports configured with service instances. Load-balancing on port channels is based on the
MAC address or IP address of the traffic flow on the EtherChannel interface.
This example configures a service instance on an EtherChannel port channel. Configuration on the ports
in the port channel are independent from the service instance configuration.
Switch (config)# interface port-channel 4
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport allowed vlan none
Switch (config-if)# service instance 2 ethernet
Switch (config-if-srv)# encapsulation dot1q 20
Switch (config-if-srv)# bridge-domain 2
