Clears the CRC error count associated with a port and arbitrated loop physical address (AL_PA).
SYNOPSIS
perfclearalpacrc [slot/]port [ALPA]
DESCRIPTION
Use this command to clear a specific cyclic redundancy check (CRC) error counter associated with a
specific port and AL_PA, or all such counters on a port.
NOTES
This command requires an Advanced Performance Monitoring license.
This command is not supported on virtual FC ports (VE/VEX_Port), EX_Port, M (Mirror) ports and GbE
ports.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

OPERANDS
This command has the following operands:
slot
For bladed systems only, specifies the slot number of the port on which the
monitor is to be added, followed by a slash (/).
port
Specifies the number of the port on which the monitor is to be added, relative to its
slot for bladed systems. Use switchShow for a list of valid ports.
ALPA
Specifies the AL_PA address to clear the CRC error counter for a particular
device. This operand is optional; if ALPA is not specified, this command clears the
counters for all devices attached to the specified port.
EXAMPLES
To clear the CRC count on a particular AL_PA on a port and then clear the CRC count for all AL_PAs on
a port:
switch:admin> perfclearalpacrc 2/15 0x59
CRC error count at ALPA 0x59 on port 31 is cleared.
switch:admin> perfclearalpacrc 2/15
This will clear all ALPA CRC Counts on port 31
Do you want to continue? (yes, y, no, n) y
Please wait ...
All alpa CRC counts are cleared on port 31.
