Output Fields

Table 1 lists the output fields for the show services l2tp tunnel command. Output fields are listed in the approximate order in which they appear.

Table 1: show services l2tp tunnel Output Fields

Field Name	Field Description
Interface	Name of an adaptive services interface.
Tunnel group	Name of a tunnel group.
Local ID	Numeric identifier of the local endpoint of the tunnel, as assigned by the L2TP network server (LNS).
Remote ID	Numeric identifier of the remote endpoint of the tunnel, as assigned by the L2TP access concentrator (LAC).
Remote IP	IP address of the peer endpoint of the tunnel.
Sessions	Number of L2TP sessions established through the tunnel.
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. Terminate—The tunnel is terminating. Unknown—The tunnel is not connected to the router.
Local IP	IP address of the local endpoint of the tunnel.
Local name	Name used for local tunnel endpoint during tunnel negotiation.
Remote name	Name used for remote tunnel endpoint during tunnel negotiation.
Max sessions	Maximum number of sessions that can be established on this tunnel.
Window size	Number of control messages that can be sent without receipt of an acknowledgment.
Hello interval	Interval between the transmission of hello messages, in seconds.
Create time	Date and time when the tunnel was created. While the LNS and LAC are connected, this value should correspond to the router's uptime. If connection to the LAC is severed, the State changes to Unknown and the Create time value resets.
Up time	Amount of time elapsed since the tunnel became active, in hours, minutes, and seconds.
Idle time	Amount of time elapsed since the tunnel became idle, in hours, minutes, and seconds.
Statistics since	Date and time when collection of the following statistics began: Control Tx—Amount of control information transmitted, in packets and bytes. Control Rx—Amount of control information received, in packets and bytes. Data Tx—Amount of data transmitted, in packets and bytes. Data Rx—Amount of data received, in packets and bytes. Errors Tx—Number of errors transmitted, in packets. Errors Rx—Number of errors received, in packets.
