    show services l2tp session

    Syntax

    show services l2tp session <brief | detail | extensive | statistics><interface sp-fpc/pic/port> <local-gateway gateway-address><local-gateway-name gateway-name><local-session-id session-id><local-tunnel-id tunnel-id><peer-gateway gateway-address><peer-gateway-name gateway-name><tunnel-group group-name><user username>

    Release Information

    Command introduced before Junos OS Release 7.4.

    Description

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

    (MX Series routers only) Display a list of active L2TP sessions for LAC.

    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.

    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 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.

    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.

    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.
