Enabling IP Source Guard for a LAG Port for a VLAN

You can enable IP Source Guard for a LAG port for a VLAN.
  1. Enter global configuration mode.
    device# configure terminal
  2. Configure the port-based VLAN.
    device(config)# vlan 12
  3. Add port LAG 9 as a tagged port.
    device(config-vlan-12)# tagged lag 9
    
  4. Enable Source Guard on the tagged LAG port.
    device(config-vlan-12)# source-guard enable lag 9

The following example configures IP Source Guard for a tagged LAG port for a VLAN.

device# configure terminal
device(config)# vlan 12
device(config-vlan-12)# tagged lag 9
device(config-vlan-12)# source-guard enable lag 9
