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

Clearing the CRC Error Count

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

Using End-to-end Performance Monitoring

End-to-end performance monitoring counts the number of words and CRC errors
in Fibre Channel frames for a specified Source ID (SID) and Destination ID (DID)
pair. An end-to-end performance monitor counts the number of:
To enable end-to-end performance monitoring, you must configure an end-to-end
monitor on a port, specifying the SID-DID pair. The monitor counts only those
frames with matching SID and DID.
Each SID or DID has three fields, listed in the following order:
38
sw1:admin> perfShowAlpaCrc 3, 0x01
The CRC count at ALPA 0x1 on port 3 is 0x000000002.
sw1:admin> perfClrAlpaCrc 3
No ALPA value is specified. This will clear all ALPA CRC
counts on port 3. Do you want to continue? (yes, y, no, n):
[no]
Please wait ...
All alpa CRC counts are cleared on port 3.
admin> perfClrAlpaCrc 3, 0x01
CRC error count at ALPA 0x1 on port 3 is cleared.
