Field DescriptionField Name
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.

User-configured interface description.Description
Number of forwarding classes supported and in use for the interface.Forwarding classes
Ingress Queues Information (not shown for all interfaces)
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.
Ingress queues
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.
Transmitted
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.
