Disable IP Source Guard for IPv4 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 IPv4 addresses:

   no ip source verify

3. Verify IPSG configuration:

   show ip source verify 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 ip source verify

Verify the configuration.

Switch:1(config-if)#show ip source verify interface gigabitEthernet 4/1
