show services l2tp session

Interface

(LNS only) Name of an adaptive services interface.

Tunnel group

(LNS only) Name of a tunnel group.

Tunnel local ID

Identifier of the local endpoint of the tunnel, as assigned by the L2TP network server (LNS).

Session local ID

Identifier of the local endpoint of the L2TP session, as assigned by the LNS.

Session remote ID

Identifier of the remote endpoint of the L2TP session, as assigned by the L2TP access concentrator (LAC).

State

State of the L2TP session:

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

• closed—Session is being closed.

• destroyed—Session is being destroyed.

• clean-up—Session is being cleaned up.

• lns-ic-accept-new—New session is being accepted.

• lns-ic-idle—Session has been created and is idle.

• lns-ic-reject-new—New session is being rejected.

• lns-ic-wait-connect—Session is waiting for the peer's incoming call connected (ICCN) message.

Bundle ID

(LNS only) Bundle identifier. Indicates the session is part of a multilink bundle. Sessions that have a blank Bundle field are not participating in the Multilink Protocol. Sessions in a multilink bundle might belong to different L2TP tunnels. For L2TP output organized by bundle ID, issue the show services l2tp multilink extensive command.

Mode

(LNS) Mode of the interface representing the session: shared or exclusive.

(LAC) Mode of the interface representing the session: shared or dedicated. Only dedicated is currently supported for the LAC.

Local IP

IP address of local endpoint of the Point-to-Point Protocol (PPP) session.

Remote IP

IP address of remote endpoint of the PPP session.

Username

(LNS only) Name of the user logged in to the session.

Assigned IP address

(LNS only) IP address assigned to remote client.

Local name

For LNS, name of the LNS instance in which the session was created. For LAC, name of the LAC.

Remote name

For LNS, name of the LAC from which the session was created. For LAC, name of the LAC instance.

Local MRU

(LNS only) Maximum receive unit (MRU) setting of the local device, in bytes.

Remote MRU

(LNS only) MRU setting of the remote device, in bytes.

Tx speed

Transmit speed of the session conveyed from the LAC to the LNS, in bits per second (bps) and the source method from which the speed is derived.

Starting in Junos OS Release 14.1, either the initial (initial) line speed or both the initial and current (update) line speeds can be displayed on MX Series routers:

• When connection speed updates are not enabled, then only the initial line speed is displayed.

• When connection speed updates are enabled, then both the initial and the current speeds are displayed.

For Junos OS Release 17.2 and Release 17.3, only the current (update) line speed can be displayed on MX Series routers.

Starting in Junos OS Release 17.4R1, once again either the initial (initial) line speed or both the initial and current (update) line speeds can be displayed on MX Series routers.

Starting in Junos OS Release 15.1, when the Tx connect speed method is set to none, the value of zero (0) is displayed.

Rx speed

Receive speed of the session conveyed from the LAC to the LNS, in bits per second (bps) and the source method from which the speed is derived.

Starting in Junos OS Release 14.1, either the initial (initial) line speed or both the initial and current (update) line speeds can be displayed on MX Series routers:

• When connection speed updates are not enabled, then only the initial line speed is displayed.

• When connection speed updates are enabled, then both the initial and the current speeds are displayed.

For Junos OS Release 17.2 and Release 17.3, only the current (update) line speed can be displayed on MX Series routers.

Starting in Junos OS Release 17.4R1, once again either the initial (initial) line speed or both the initial and current (update) line speeds can be displayed on MX Series routers.

Starting in Junos OS Release 15.1, when the Tx connect speed method is set to none, the value of zero (0) is displayed.

Bearer type

Type of bearer enabled:

• 0—Might indicate that the call was not received over a physical link (for example, when the LAC and PPP are located in the same subsystem).

• 1—Digital access requested.

• 2—Analog access requested.

• 4—Asynchronous Transfer Mode (ATM) bearer support.

Framing type

Type of framing enabled:

• 1—Synchronous framing

• 2—Asynchronous framing

LCP renegotiation

(LNS only) Whether Link Control Protocol (LCP) renegotiation is configured: On or Off.

Authentication

Type of authentication algorithm used: Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP).

Interface ID

(LNS only) Identifier used to look up the logical interface for this session.

Interface unit

Logical interface for this session.

Call serial number

Unique serial number assigned to the call.

Policer bandwidth

Maximum policer bandwidth configured for this session.

Policer burst size

Maximum policer burst size configured for this session.

Firewall filter

Configured firewall filter name.

Session encapsulation overhead

Overhead allowance configured for this session, in bytes.

Session cell overhead

Cell overhead activation (On or Off).

Create time

Date and time when the call was created.

Up time

Length of time elapsed since the call became active, in hours, minutes, and seconds.

Idle time

Length of time elapsed since the call became idle, in hours, minutes, and seconds.
