perfClearAlpaCrc

Clears the CRC error count associated with a port and arbitrated loop physical address (AL_PA).

Synopsis perfclearalpacrc [slotnumber/]portnumber [ALPA]

Description Use this command to clear a specific CRC error counter associated with a specific port and AL_PA,

or all such counters on a port.

This command requires a Brocade 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 Admin Domain restrictions that may be in place.

Operands This command has the following operands:

slotnumber For bladed systems only, this operand specifies the slot number of the port

on which the monitor is to be added, followed by a slash (/).

portnumber 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 Specify the AL_PA address if you want to clear the CRC error counter for a

particular device. This operand is optional; if omitted, 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.
