Field Description
On Gigabit Ethernet IQ2 PICs only, total number of ingress queues supported on the specified interface.
On Gigabit Ethernet IQ2 PICs only, total number of ingress queues in use on the specified interface.
Total number of output queues supported on the specified interface.
Total number of output queues in use on the specified interface.
Total number of egress queues supported on the specified interface.
Total number of egress queues in use on the specified interface.
Queue number.
CoS queue number and its associated user-configured forwarding class name. Displayed on IQ2
interfaces.
• Queued packets—Number of queued packets.
• Transmitted packets—Number of transmitted packets.
• Dropped packets—Number of packets dropped by the ASIC's RED mechanism.
(Logical interfaces on IQ PICs only) Maximum number of bytes up to which the logical interface can
burst. The burst size is based on the shaping rate applied to the interface.
Forwarding class name.
Number of packets queued to this queue.
NOTE: For Gigabit Ethernet IQ2 interfaces, the Queued Packets count is calculated by the Junos OS
interpreting one frame buffer as one packet. If the queued packets are very large or very small, the
calculation might not be completely accurate for transit traffic. The count is completely accurate for
traffic terminated on the router.
Number of bytes queued to this queue. The byte counts vary by PIC type. For more information, see
Table 19 on page 66.
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.
NOTE: For layer 2 statistics, see “Overhead for Layer 2 Statistics” on page 60
