Enable IPsec on an Interface

1. Enter Interface Configuration mode:

   enable

   configure terminal

   followed by one of the following:

   • interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

   • interface loopback <1–256>

   • interface vlan <1–4059>

   

   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. Enable IPsec on an IPv6 interface:

   ipv6 ipsec enable

3. Enable IPsec on an IPv4 interface:

   ip ipsec enable

Example

Enable IPsec for IPv6 on VLAN 100:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#interface vlan 100
Switch:1(config-if)#ipv6 ipsec enable
