Usage Information
NOTE: If you configure the BGP unnumbered feature on a VLAN, do not apply the RA guard policy for that VLAN.
  • This command is applicable for physical and port-channel interfaces.
  • You must associate the interface as a member port with the VLAN or VLANs that you specify in this command.
  • If you specify a VLAN ID that is not yet created in the system, the policy is applied when the VLAN is configured, becomes active, and is associated with this interface.
  • If you choose the all option:
    • The system applies the RA guard policy to all the VLANs that are associated with this interface.
    • The system applies the RA guard policy to any new VLANs that you associate with this interface in the future.
  • When you apply the RA guard policy to a primary VLAN, the primary VLAN works as a regular VLAN. The RA packets received on the promiscuous ports flood to all the member ports of the primary and secondary VLANs.
  • When you apply the policy to a secondary VLAN, the RA packets received on secondary ports are flooded to the member ports of the primary VLAN.
    NOTE: If the secondary ports are connected to host devices, ensure that you configure the device role as host using the device-role command.
