    Display the PIC Interface Status Information

    Purpose

    To display the status information of each configured PIC interfaces.

    Action

    To display the status of each configured interface, use the following operational mode command:

    user@host>show interfaces terse

    Sample Output

    user@host> show interfaces terse
    Interface       Adman Link Port Local             Remote
    so-0/0/0        up    up  
    so-0/0/0.0      up    up   inet  192.168.36.201      --> 192.168.36.200
    so-0/1/0        up    down
    so-0/1/1        up    down
    e1-0/2/0        up    down
    e1-0/2/1        up    down
    t1-1/0/0:1      up    down
    t1-1/0/0:2      up    down
    gr-2/0/0        up    up  
    ip-2/0/0        up    up  
    [...Output truncated...]
    

    Meaning

    The command output shows the names of all interfaces configured on the router. The interface name indicates the media type-fpc/pic/port (for example, so-0/0/0.0). It shows whether the interface is on (up) or off (down) and whether the link state is up or down. Additionally, the output shows the protocol configured on that interface and the local address of the interface, as well as the address of the remote side of a connection for point-to-point interfaces. Refer to the PIC for port numbering.

    A line in the sample output shows the status of a SONET interface on FPC 0, PIC 0, port 0, and logical unit number 0. The status of the interface is up. The link status is up. The protocol configured on the interface is inet. The local interface IP address is 192.168.36.201 and the remote IP address is 192.168.36.200.

    The interface is configured with a /32 subnet. If you configure the interface with a different subnet, the output will be different.

    For more detailed information about monitoring interfaces, see the Junos OS System Basics and Services Command Reference.

    To view more detailed information about a particular interface, use the show interfaces interface-name brief command. The command output shows the interface status, link-level type, loopback, device flags, interface flags, keepalive settings, keepalive input, active alarms, and defects.

    To view interface status information, use the show interface descriptions command. This command displays the interface status and the description given when configured on the router.

    show interfaces terse <interface-name> show interfaces <interface-name> brief
