Using the outbound queue monitor

NOTE: Outbound queue monitoring is not supported on HP 3800 switches.

When QoS is used to prioritize traffic, different kinds of traffic can be assigned to different egress

queues. If there is a great deal of traffic, it is desirable to be able determine if some traffic to the

lower priority queues was dropped. This feature allows the egress queues for one port to be

monitored for dropped packets.

Syntax:

[no] qos watch-queue port out

Configures the switch to start monitoring the specified port for the dropped packets

for each queue. Disabling and then re-enabling monitoring on a port clears the

per-queue dropped packet counters. For example:

HP Switch(config)#: qos watch-queue 5 out

The no form of the command stops the collection of dropped traffic information.

(Default: disabled)

Viewing per-queue counts

The show interface queues command displays the number of dropped packets for each

queue for the configured port. The port must have been configured with the qos watch-queue

command. Ports that have not been configured display zero values for the queue counts.
