Queue Depth Monitoring - Alcatel-Lucent 7450 Quality Of Service Manual

Remarking the DSCP/prec based on the profile result of egress policing must be enabled as
the follows under the related policer configuration:

Queue Depth Monitoring

Queue depth monitoring gives more visibility to the operator of the queue depths being
experienced on a set of queues when the traffic is bursty. The instantaneous depth of a queue
can be seen using the show pools command, whereas queue depth monitoring shows the
variation in queue depth over a period of time. It is applicable to SAP ingress unicast and
multipoint queues and SAP egress queues, and for ingress and egress access and network
queue group queues used by any service or network interfaces. The monitoring uses a polling
mechanism by the line card CPU. Consequently, the results provided are statistical in nature.
This is supported on FP2- and higher-based line cards.
An override (monitor-depth) is used to enable queue depth monitoring, which is configured
under the SAP or queue group queue-overrides. There are show and clear commands, using
the queue-depth parameter, for both service SAPs and port queue groups with associated
MIB variables.
The configuration below gives an example of enabling the monitoring of the depth of queue
1 on an Epipe SAP.
