Using Advanced Performance Monitoring

AL_PA Performance Monitoring

AL_PA performance monitoring allows you to track and display the number of CRC errors that

have occurred on frames sent to each AL_PA on a specific port. No monitor configuration is

necessary for AL_PA performance monitoring.

Use the perfShowAlpaCrc command to display the CRC error count for all AL_PA devices or 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:

sw1:admin> perfShowAlpaCrc 3

AL_PA

--------------------

0x01

0x02

0x04

Example 2. The following command displays the CRC error count for AL_PA 0x01 on port 3:

sw1:admin> perfShowAlpaCrc 3, 0x01

The CRC count at ALPA 0x1 on port 3 is 0x000000002.

Use the perfClrAlpaCrc command to clear the CRC error count for AL_PA devices on a specific

port. You can clear the error counts for all the AL_PA devices on a port or for a specific AL_PA.

Example 1. The following command clears the CRC error count for all AL_PA devices on port 3:

sw1:admin> perfClrAlpaCrc 3

This will clear all ALPA CRC counts on port 3.

Please wait ...

All alpa CRC counts are cleared on port 3.

Example 2. The following command clears the CRC error count for AL_PA 1 on port 3:

admin> perfClrAlpaCrc 3, 0x01

CRC error count at ALPA 0x1 on port 3 is cleared.
