Telnet Commands; Using Al_Pa Error Performance Monitoring; Displaying The Crc Error Count - HP StorageWorks MSA 2/8 - SAN Switch User Manual

Telnet Commands

The telnet commands for Advanced Performance Monitoring become available
through the shell "admin" account when the Advanced Performance Monitoring
license key is installed. To use a telnet command, log into the relevant switch with
administrative privileges, enter the command along with any required arguments,
and press Enter.
Using telnet commands, you can track the following:
For a description of all the telnet commands provided for performance
monitoring, refer to the HP StorageWorks Fabric OS Version 3.1.x/4.1.x
Reference Guide.

Using AL_PA Error Performance Monitoring

AL_PA error performance monitoring tracks and displays the number of CRC
errors that have occurred on frames sent to each AL_PA on a specific port.
AL_PA-based error performance monitoring does not require an explicit
configuration. The switch hardware and firmware automatically monitor CRC
errors for all valid AL_PAs.

Displaying the CRC Error Count

Use the perfShowAlpaCrc command to display the CRC error count for all
AL_PA devices for a single AL_PA on a specific port. The port must be an active
L_Port.
Example 1. This command displays the CRC error count for all AL_PA devices
on port 3:
