Configuring VE route-only mode on a LAG port

  1. Enter global configuration mode. 
    device# configure terminal
  2. Create a VLAN. 
    device(config)# vlan 100
  3. Specify a port-channel interface. 
    device# configure terminal
device(config)# interface port-channel 1
  4. Enter the switchport command to configure Layer 2 characteristics. 
    device(config-Port-channel-1)# switchport
  5. Specify trunk mode. 
    device(config-Port-channel-1)# switchport mode trunk
  6. Tag the port to a VLAN. 
    device(config-Port-channel-1)# switchport trunk allowed vlan add 100
  7. Enable tagging on native VLAN traffic. 
    device(config-Port-channel-1)# switchport trunk tag native-vlan
  8. Enter the route-only command top enable Layer 3 routing exclusively on the port. 
    device(config-Port-channel-1)# route-only
    Use the no route-only command to revert to default Layer 2 and Layer 3 behavior.
  9. Enable the interface and exit to global configuration mode. 
    device(config-Port-channel-1)# no shutdown
device(config-Port-channel-1)# exit
  10. Verify the port-channel configuration. 
    device(config-Port-channel-1)# do show running-cocnfig interface port-channel 1
 interface Port-channel 1
 switchport
 switchport mode trunk
 switchport trunk allowed vlan add 100,200
 switchport trunk tag native-vlan
 route-only
 no shutdown
  11. Enter virtual Ethernet (VE) configuration mode and specify the VLAN. 
    device(config)# interface ve 100
  12. Assign an IP address and mask and enable the interface. 
    device(config-Ve-100)# ip address 10.2.2.2/24
device(config-Ve-100)# no shutdown
  13. Verify the VE configuration. 
    device(config-Ve-100)# )# do show running interface ve 100
interface Ve 100
 ip proxy-arp
 ip address 10.2.2.2/24
 no shutdown
