    Table 1: show interfaces queue Output Fields

    Field Name

    Field Description

    Physical Interface and Forwarding Class Information

    Physical interface

    Name of the physical interface.

    Enabled

    State of the interface. Possible values are:

    • Administratively down, Physical link is Down—The interface is turned off, and the physical link is inoperable.
    • Administratively down, Physical link is Up—The interface is turned off, but the physical link is operational and can pass packets when it is enabled.
    • Enabled, Physical link is Down—The interface is turned on, but the physical link is inoperable and cannot pass packets.
    • Enabled, Physical link is Up—The interface is turned on, and the physical link is operational and can pass packets.

    Interface index

    Index number of the physical interface, which reflects its initialization sequence.

    SNMP ifIndex

    SNMP index number for the physical interface.

    Description

    User-configured interface description.

    Forwarding classes

    Number of forwarding classes supported and in use for the interface.

    Ingress Queues Information (not shown for all interfaces)

    Ingress queues

    Number of input queues supported and in use on the specified interface. For an interface on a line card with oversubscribed ports, the ingress queue handles low priority traffic on the interface.

    Transmitted

    Transmission statistics for the queue:

    • Packets—Number of packets transmitted by this queue.
    • Bytes—Number of bytes transmitted by this queue.
    • Tail-dropped packets—Number of packets dropped because the queue buffers were full.

    PFE chassis queues

    For an interface on a line card with oversubscribed ports, the number of Packet Forwarding Engine chassis queues supported and in use for the port group to which the interface belongs. The Packet Forwarding Engine chassis queue for a port group handles high priority traffic from all the interfaces in the port group.

    Egress Queues Information

    Egress queues

    Number of output queues supported and in use on the specified interface.

    Queue

    CoS queue number.

    Queued

    This counter is not supported on EX Series switches.

    Transmitted

    Number of packets and bytes transmitted by this queue. Information on transmitted packets and bytes can include:

    • Packets—Number of packets transmitted.
    • Bytes—Number of bytes transmitted.
    • Tail-dropped packets—Number of arriving packets dropped because output queue buffers were full.
    • RED-dropped packets—Number of packets dropped because of random early detection (RED).
      • Low—Number of low loss priority packets dropped because of RED.
      • High—Number of high loss priority packets dropped because of RED.
    • RED-dropped bytes—Number of bytes dropped because of random early detection (RED).
      • Low—Number of low loss priority bytes dropped because of RED.
      • High—Number of high loss priority bytes dropped because of RED.

    Packet Forwarding Engine Chassis Queues

    For an interface on a line card with oversubscribed ports, the number of Packet Forwarding Engine chassis queues supported and in use for the port group to which the interface belongs. The queue statistics reflect the traffic flowing on all the interfaces in the port group.
