Table 137: show class-of-service interface Output Fields (continued)
Field DescriptionField Name
Queue number.Queue
Forwarding class name.Forwarding classes
Number of packets queued to this queue.Queued Packets
Number of bytes queued to this queue. The byte counts vary by PIC type.Queued Bytes
Number of packets transmitted by this queue. When fragmentation occurs on the egress interface,
the first set of packet counters shows the postfragmentation values. The second set of packet counters
(displayed under the Packet Forwarding Engine Chassis Queues field) shows the prefragmentation
values.
Transmitted Packets
Number of bytes transmitted by this queue. The byte counts vary by PIC type.Transmitted Bytes
Number of packets dropped because of tail drop.Tail-dropped packets
Number of packets dropped because of random early detection (RED).
• (M Series and T Series routers only) On M320 and M120 routers and the T Series routers, the total
number of dropped packets is displayed. On all other M Series routers, the output classifies dropped
packets into the following categories:
• Low, non-TCP—Number of low-loss priority non-TCP packets dropped because of RED.
• Low, TCP—Number of low-loss priority TCP packets dropped because of RED.
• High, non-TCP—Number of high-loss priority non-TCP packets dropped because of RED.
• High, TCP—Number of high-loss priority TCP packets dropped because of RED.
• (MX Series routers with enhanced DPCs, and T Series routers with enhanced FPCs only) The output
classifies dropped packets into the following categories:
• Low—Number of low-loss priority packets dropped because of RED.
• Medium-low—Number of medium-low loss priority packets dropped because of RED.
• Medium-high—Number of medium-high loss priority packets dropped because of RED.
• High—Number of high-loss priority packets dropped because of RED.
NOTE: Due to accounting space limitations on certain Type 3 FPCs (which are supported in M320
and T640 routers), this field does not always display the correct value for queue 6 or queue 7 for
interfaces on 10-port 1-Gigabit Ethernet PICs.
