none

Remote IP

IP address of the peer endpoint of the tunnel.

All levels

Sessions

Number of L2TP sessions established through the tunnel.

All levels

Switched-sessions

Number of L2TP sessions established by tunnel switching.

All levels

State

State of the L2TP tunnel:

  • cc_responder_accept_new—The tunnel has received and accepted the start control connection request (SCCRQ).

  • cc_responder_reject_new—The tunnel has received and rejected the SCCRQ.

  • cc_responder_idle—The tunnel has just been created.

  • cc_responder_wait_ctl_conn—The tunnel has sent the start control connection response (SCCRP) and is waiting for the start control connection connected (SCCCN) message.

  • clean-up—The tunnel is being cleaned up.

  • closed—The tunnel is being closed.

  • destroyed—The tunnel is being destroyed.

  • Established—The tunnel is operating. This is the only state supported for the LAC.

  • Terminate—The tunnel is terminating.

  • Unknown—The tunnel is not connected to the router.

All levels

Tunnel local ID

On the LNS, number assigned by the LNS that identifies the local endpoint of the tunnel relative to the LNS: the LNS.

On the LAC, number assigned by the LAC that identifies the local endpoint of the tunnel relative to the LAC: the LAC.

detailextensive

Tunnel remote ID

On the LNS, number assigned by the LAC that identifies the remote endpoint of the tunnel relative to the LNS: the LAC.

On the LAC, number assigned by the LNS that identifies the remote endpoint of the tunnel relative to the LAC: the LNS.

detailextensive

Tunnel Name

(LAC only) Name of the created tunnel. This value includes the destination name followed by the value of the RADIUS Tunnel-Assignment-ID VSA [82].

detailextensive

Local IP

IP address of the local endpoint of the tunnel.

detailextensive

Local name

Name used for local tunnel endpoint during tunnel negotiation.

detailextensive

Remote name

Name used for remote tunnel endpoint during tunnel negotiation.

detailextensive

(LAC only) Peer resynchronization mechanism (PRM) in effect for the tunnel:

  • Failover protocol

  • Silent failover—Recovery takes place in the failed endpoint only using the proprietary silent failover protocol.

extensive

Window size

Number of control messages that can be sent without receipt of an acknowledgment.

extensive

Hello interval

Interval between the transmission of hello messages, in seconds.

extensive

Create time
