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 details.
This command is not supported on all platforms. Refer to the Fabric OS Administrator's Guide for
specific hardware support.
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.
