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 port.
