perfShowAlpaCrc Displays the CRC error count by port or by arbitrated loop physical address (AL_PA). Synopsis perfshowalpacrc [slotnumber/]portnumber [ALPA] Availability all users NOTE: This command requires a Performance Monitor license. 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. When the count is over 32 bits, the CRC count value is displayed in hexadecimal; otherwise, CRC count is displayed in decimal format. Operands This command has the following operands: slotnumber portnumber ALPA 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 (/). 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. 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. Optionally, a comma can separate the operands. A space is required to separate the operands even when using commas.
