perfShowAlpaCrc

Displays the CRC error count by port or by arbitrated loop physical address (AL_PA).

Synopsis perfshowalpacrc [slotnumber/]portnumber [ALPA]

Description Use this command to display the CRC error count of one or all devices attached to a port. If the

AL_PA operand is specified, only the CRC count for that AL_PA device is displayed. If the AL_PA

operand is not specified, the CRC count for all the AL_PA devices on a specified port are displayed.

CRC count is a 64-bit counter. The CRC count value is displayed in hexadecimal.

Notes This command requires a Brocade Advanced Performance Monitoring license.

This command is not supported on the Brocade 200E, 4100, and 48000 platforms.

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 displayed,

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 get the CRC errors for a particular

device. This operand is optional; if omitted, this command displays CRC error

counts for all devices attached to the specified port.

Examples To display the CRC error count for all AL_PA devices on a port:

switch:admin> perfshowalpacrc 2/4
