Monitoring Al_Pas; Adding End-To-End Monitors - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Monitoring AL_PAs

You can use the perfShowAlpaCrc command to display the CRC error count for all AL_PA devices or
for a single AL_PA on a specific active L_Port.
The following example displays the CRC error count for all AL_PA devices on a port:
switch:admin> perfshowalpacrc 1/1
AL_PA
--------------------
0xd9
The following example displays the CRC error count for a single AL_PA device on a port:
switch:admin> perfshowalpacrc 1/1, 0xd9
The CRC count at ALPA 0xd9 on port 1 is 0x000000000.
The following example clears the CRC error count:
switch:admin> perfclearalpacrc 1/1, 0xd9
CRC error count at AL_PA 0xd9 on port 1 is cleared.
switch:admin> perfclearalpacrc 1/1
No AL_PA value is specified. This will clear all AL_PA CRC
counts on port 1. Do you want to continue? (yes, y, no, n): [no] y
Please wait ...
All alpa CRC counts are cleared on port 1.
In 3.1.0, 4.1.0, and later versions, you can use the portStatsClear command to clear AL_PA- based
CRC error counters for all the ports in the same group.
NOTE: For end-to-end monitors, CRC counters are not displayed on the 4/8 SAN Switch, 4/16 SAN
Switch, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 400 Multi-protocol Router, 4/256 SAN
Director, and DC Director switches.

Adding end-to-end monitors

An end-to-end monitor counts the following items for a port: number of words received, number of words
transmitted, and number of CRC errors detected in frames.
NOTE: Only one mask per port can be set. When you set a mask, all existing end-to-end monitors are
deleted.
