perfShowAlpaCrc 2 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.
