Juniper ACX2000 Configuration Guide

NOTE: For rate-limited interfaces hosted on other types of hardware,
rate-limit packet-drop operations occur after packets are queued for
transmission scheduling. For these other interface types, the statistics for
queued traffic include the packets that are later dropped due to rate limiting,
and consequently the displayed statistics for queued traffic equals the sum
of the statistics for transmitted and rate-limited traffic.
On M Series routers (except for the M320 and M120 routers), this command is valid only
for a PIC installed on an enhanced Flexible PIC Concentrator (FPC).
Queue statistics for aggregated interfaces are supported on the M Series and T Series
routers only. Statistics for an aggregated interface are the summation of the queue
statistics of the child links of that aggregated interface. You can view the statistics for a
child interface by using the show interfaces statistics command for that child interface.
When you configure tricolor marking on a 10-port 1-Gigabit Ethernet PIC, for queues 6
and 7 only, the output does not display the number of queued bytes and packets, or the
number of bytes and packets dropped because of RED. If you do not configure tricolor
marking on the interface, these statistics are available for all queues.
For the 4-port Channelized OC12 IQE PIC and 1-port Channelized OC48 IQE PIC, the
Packet Forwarding Engine Chassis Queues field represents traffic bound for a particular
physical interface on the PIC. For all other PICs, the Packet Forwarding Engine Chassis
Queues field represents the total traffic bound for the PIC.
For Gigabit Ethernet IQ2 PICs, the show interfaces queue command output does not
display the number of tail-dropped packets. This limitation does not apply to Packet
Forwarding Engine chassis queues.
When fragmentation occurs on the egress interface, the first set of packet counters shows
the postfragmentation values. The second set of packet counters (under the Packet
Forwarding Engine Chassis Queues field) shows the prefragmentation values.
The behavior of the egress queues for the Routing Engine-Generated Traffic is not same
as the configured queue for MLPPP and MFR configurations.
For information about how to configure CoS, see the Junos OS Network Interfaces Library
for Routing Devices. For related CoS operational mode commands, see the CLI Explorer.
