Chapter 11 Managing Packet Queue Congestion
Verifying and Monitoring Layer 3 Packet Dropping
For diagnostic purposes, use any of the following commands in privileged EXEC mode:
Note The show pxf commands are entered as show hardware pxf on the PRE1.
Command Purpose
Router# show pxf cpu queue interface
Displays the output queue statistics for a particular interface. If
you do not specify an interface, the route processor queue
statistics display.
Use this command to determine if traffic is being properly
distributed.
Note Each interface has two queues: low and high priorities.
When you enter this command, the output that displays
includes the following fields:
wq_len indicates the current depth of the output queue
for the interface.
wq_limit_drop indicates the number of packets dropped
because the output queue was full.
packet xmit indicates the number of packets that have
been output.
byte xmit indicates the number of bytes that have been
output.
Router# show pxf cpu queue interface summary
Displays queue scaling information such as:
• Number of queues and recycled queues
• Number of available queue IDs (QIDs)
• Number of packet buffers, recycled packet buffers, and free
packet buffers
Note In Cisco IOS Release 12.2(33)SB, this command was
modified to display only the physical interface and the
number of logical links, and was implemented on the
PRE3 and PRE4. The command output no longer displays
the number of priority queues, class queues, and so on.
Router# show pxf cpu schedule
Displays the rates at which each interface gets packets from the
forwarding engine.
