Release Information

Command introduced before JUNOS Release 7.4.

Description

(M10i and M7i routers only) Display a list of active L2TP sessions.

Options

none — Display standard information about all active L2TP sessions.

brief | detail | extensive | statistics — (Optional) Display the specified level of output. Use the statistics option to display packet and byte counts for each session.

interface sp-fpc/pic/port — (Optional) Display L2TP session information for only the specified adaptive services interface.

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.

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.

Field Name

Field Description

Level of Output

Interface

Name of an adaptive services interface.

All levels

Tunnel group

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.
  • 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

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.
