Queue depth monitoring

General information

Queue depth monitoring provides insight into traffic flows on queues, which can help to fine-tune port service allocations and QoS policies, for capacity planning and SLA compliance.

The NFM-P supports the configuration of queue depth monitoring using overrides for access ingress, access egress, and network egress queue groups, and for L2 and L3 access egress interfaces.

• For egress queue group overrides on Ethernet ports, see To add a queue group to an Ethernet port.

• For QoS policy overrides for L2 and L3 access egress interfaces, see To configure QoS policy overrides on an L2 or L3 access interface.

Configuration includes options for fast polling, which can provide more accurate results, and for violation thresholds, which generate notifications when exceeded. Depth monitoring results and notifications are not available in the NFM-P, but can be obtained from NEs using CLI or telemetry, depending on NE version and release support. See the NE documentation for more information.
