About this task
Attaches or detaches a RA Guard policy on the specific interface.
Procedure
- 
        Enter GigabitEthernet Interface
          Configuration mode:
        
          enable configure
              terminal 
            interface GigabitEthernet
              {slot/port[/sub-port][-slot/port[/sub-port]][,...]}  Note    If the platform supports channelization and the port is channelized, you must also
              specify the sub-port in the format slot/port/sub-port. 
 
- 
                Apply a RA Guard policy.
                
                    ipv6 fhs ra-guard
                            attach-policy WORD<1–64> Note    RA Guard device-role on the port has to be configured as 'router' before
                                attaching any RA Guard policy to the port. If device-role on the port is not 'router',
                                this command will fail with an appropriate error message. 
 
 
- 
                Detach a RA Guard policy from an interface.
                
                    no ipv6 fhs
                            ra-guard attach-policy OR default ipv6 fhs
                            ra-guard attach-policy 
 
- Enable device role
verification attached to the port.
ipv6 fhs ra-guard device-role
                            {router|host} attach-policy WORD<1-64> Note    A DHCPv6 Guard policy can be attached to a port only if the device-role
                                configured on that port is 'server'.
