The CPAM highlighted path audit verifies each interface that is highlighted in a path. The CPAM compares each audit calculation to a threshold that you configure. The audit threshold verification includes:

• Ethernet and POS interface utilization and error rates

• IP interface utilization and error rates

• SROS queue utilization and errors

The audit uses a count that is based on the difference between the capture of two real-time statistics that are separated by a configurable time delay.

When you start an audit, the following status icons appear next to the audited links on the topology map:

• In Progress

• Failed

• Succeeded

• Indeterminate

• Not applicable (no icon)

  Note:

  Links with a not applicable status (no icon) are typically a graphical representation of a more complex connection, and audit results may be represented in an adjacent link.

On the Browse Statistics form, the following MIBs are used in highlighted path audit:

• Ethernet Stats (Ethernet Equipment)

• Interface Stats (Physical Equipment)

• Port Net Egress Accounting Stats (Physical Equipment)

• Port Net Ingress Accounting Stats (Physical Equipment)

• SONET Line Current Stats (SONET Equipment)

• SONET Section Current Stats (SONET Equipment)

Note: tmnxMcPathOperChlTable, used for FC fabric resource audit, is not visible in the NFM-P client.
