Top N Packet Drop—Network Ports report

Top N Packet Drop—Network Ports report overview

The Top N Packet Drop—Network 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, and ingress, egress, and total packet and octet dropped information.

Note: The report can be run for 7210 SAS NEs that do not support forwarding classes. For these NEs, the report will display N/A in the Forwarding Class and Queue columns.

For 7210 SAS network ports, only one of the following statistics can be collected at one time:

network ingress octets
network ingress packets
network egress octets
network egress packets

The columns for the statistics not being collected will display -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.

Limitations

Minimum and maximum throughput aggregation cannot be compared with the minimum and maximum throughput values generated from raw granularity.

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?.
