Using Advanced Performance Monitoring 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. 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: 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. 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. 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: ■ Words in frames received at the port (RX_COUNT) ■ Words in frames transmitted from the port (TX_COUNT) ■ CRC errors in frames received at the port (CRC_COUNT) 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: ■ Domain ID (DD) 38 Advanced Performance Monitoring Version 3.1.x/4.1.x User Guide
