Release Information

Command introduced before Junos OS Release 7.4.

Support for LAC on MX Series routers introduced in Junos OS Release 10.4.

Support for LNS on MX Series routers introduced in Junos OS Release 11.4.

Description

(M10i and M7i routers only) Display information about active L2TP sessions for LNS.

(MX Series routers only) Display information about active L2TP sessions for LAC and LNS.

Options

none

—

Display standard information about all active L2TP sessions.

brief | detail | extensive

—

(Optional) Display the specified level of output.

interface interface-name

—

(Optional) Display L2TP session information for only the specified adaptive services or inline services interface. The interface type depends on the line card as follows:

si-fpc/pic/port— MPCs on MX Series routers only. This option is not available for L2TP on M Series routers.
sp-fpc/pic/port—AS or Multiservices PICs on M7i, M10i, and M120 routers only. This option is not available for L2TP on MX Series routers.

local-gateway gateway-address

—

(Optional) Display L2TP session information for only the specified local gateway address.

local-gateway-name gateway-name

—

(Optional) Display L2TP session information for only the specified local gateway name.

local-session-id session-id

—

(Optional) Display L2TP session information for only the specified local session identifier.

local-tunnel-id tunnel-id

—

(Optional) Display L2TP session information for only the specified local tunnel identifier.

peer-gateway gateway-address

—

(Optional) Display L2TP session information for only the specified peer gateway address.

peer-gateway-name gateway-name

—

(Optional) Display L2TP session information for only the specified peer gateway name.

statistics

—

(Optional) Display the number of control packets and bytes transmitted and received for the session. You cannot include this option with any of the level options, brief, detail, or extensive.

tunnel-group group-name

—

(Optional) Display L2TP session information for only the specified tunnel group. To display information about L2TP CPU and memory usage, you can include the tunnel group name in the show services service-sets memory-usage group-name and show services service-sets cpu-usage group-name commands. This option is not available for L2TP LAC on MX Series routers.

user username

—

(M Series routers only) (Optional) Display L2TP session information for only the specified username.

Output Fields

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

Table 1: show services l2tp session Output Fields

Field Name	Field Description	Level of Output
Interface	(LNS only) Name of an adaptive services interface.	All levels
Tunnel group	(LNS only) Name of a tunnel group.	All levels
Tunnel local ID	Identifier of the local endpoint of the tunnel, as assigned by the L2TP network server (LNS).	All levels
Session local ID	Identifier of the local endpoint of the L2TP session, as assigned by the LNS.	All levels
Session remote ID	Identifier of the remote endpoint of the L2TP session, as assigned by the L2TP access concentrator (LAC).	All levels
State	State of the L2TP session: Established—The session is operating. This is the only state supported for the LAC. closed—The session is being closed. destroyed—The session is being destroyed. clean-up—The session is being cleaned up. lns-ic-accept-new—A new session is being accepted. lns-ic-idle—The session has been created and is idle. lns-ic-reject-new—The new session is being rejected. lns-ic-wait-connect—The session is waiting for the peer's incoming call connected (ICCN) message.	All levels
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.	All levels
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.	extensive
Local IP	IP address of local endpoint of the Point-to-Point Protocol (PPP) session.	extensive
Remote IP	IP address of remote endpoint of the PPP session.	extensive
Username	(LNS only) Name of the user logged in to the session.	All levels
Assigned IP address	(LNS only) IP address assigned to remote client.	extensive
Local name	For LNS, name of the LNS instance in which the session was created. For LAC, name of the LAC.	extensive
Remote name	For LNS, name of the LAC from which the session was created. For LAC, name of the LAC instance.	extensive
Local MRU	(LNS only) Maximum receive unit (MRU) setting of the local device, in bytes.	extensive
Remote MRU	(LNS only) MRU setting of the remote device, in bytes.	extensive
Tx speed	Transmit speed of the session conveyed from the LAC to the LNS, in bits per second (bps).	extensive
Rx speed	Receive speed of the session conveyed from the LAC to the LNS, in bits per second (bps).	extensive
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.	extensive
Framing type	Type of framing enabled: 1—Synchronous framing 2—Asynchronous framing	extensive
LCP renegotiation	(LNS only) Whether Link Control Protocol (LCP) renegotiation is configured: On or Off.	extensive
Authentication	Type of authentication algorithm used: Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP).	extensive
Interface ID	(LNS only) Identifier used to look up the logical interface for this session.	extensive
Interface unit	Logical interface for this session.	All levels
Call serial number	Unique serial number assigned to the call.	extensive
Policer bandwidth	Maximum policer bandwidth configured for this session.	extensive
Policer burst size	Maximum policer burst size configured for this session.	extensive
Firewall filter	Configured firewall filter name.	extensive

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. LCP echo req Tx—Number of LCP echo requests transmitted, in packets. LCP echo req Rx—Number of LCP echo requests received, in packets. LCP echo rep Tx—Number of LCP echo responses transmitted, in packets. LCP echo rep Rx—Number of LCP echo responses received, in packets. LCP echo Req timout—Number of LCP echo requests that timed out. LCP echo Req error—Number of errors received for LCP echo packets. LCP echo Rep error —Number of errors transmitted for LCP echo packets.	extensive
