Top N Packet Drop—Access Ports report

Top N Packet Drop—Access Ports report overview

The Top N Packet Drop—Access Ports report show the top N FECs or queues that are dropping packets. Separate reports are available for access ports and for network ports. The default display is a table showing queue, forwarding class, egress and octet dropped information.

The report can be run for 7210 SAS NEs that do not support forwarding classes. For these NEs, the report displays N/A in the Forwarding Class and Queue columns. For 7210 SAS NEs that do not support egress policies, the statistics displays as -1 and the forwarding class and queue displays as N/A.

For 7750 SR NEs that do not have packet details available, the statistics will display as -1.

It is not mandatory to configure QoS for this report since the default QoS settings apply.

Use cases

SLA monitoring—Use the report to examine traffic drop patterns, to ensure SLAs are met.

Prerequisites

The following table describes the aggregation rules that must be enabled and the accounting policies that must be configured for the NEs on which statistics are to be collected; see the NSP NFM-P Statistics Management Guide for information about configuring an accounting policy. To view the report for granularities other than raw data, the aggregation rules must be enabled; see How do I configure analytics aggregation?.
