Configures a L2TPv3 tunnel policy, used to create one or more L2TPV3 tunnels.

The L2TPv3 policy defines the control and encapsulation protocols needed for tunneling layer 2 frames between two IP nodes. This policy enables creation of L2TPv3 tunnels for transporting Ethernet frames between bridge VLANs and physical GE ports. L2TPv3 tunnels can be created between any vendor devices supporting L2TPv3 protocol.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000


l2tpv3 policy <L2TPV3-POLICY-NAME>


l2tpv3 policy <L2TPV3-POLICY-NAME>

l2tpv3 policy <L2TPV3-POLICY-NAME>

Configures an L2TPV3 tunnel policy

  • <L2TPV3-POLICY-NAME> – Specify a policy name. If a policy with the specified does not already exist, it is created. To modify an existing L2TPV3, specify its name.
