Disable IP Source Guard for IPv6 Addresses

1. 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.

2. Disable IPSG for IPv6 addresses on a port:

   no ipv6 source-guard enable

3. Verify IPSG configuration on the port:

   show ipv6 source-guard interface gigabitEthernet [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Example

Disable IPSG on port 4/1.

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface gigabitEthernet 4/1
Switch:1(config-if)no ipv6 source-guard enable

Verify the configuration.

Switch:1(config-if)#show ipv6 source-guard interface gigabitEthernet 4/1
Slot/Port  Source Guard  Number of  IPv6  Address
             Mode        address allowed  overflow count
