# Identifying boards in oamcfg operations

To indicate the board on which oamcfg is to perform a specified operation, use any of the following options:

Option | Use this option to identify a board by...
--- | ---
-b boardno | Its board number.
-g shelf:slot | Its shelf and slot location. Only valid for boards in CompactPCI chassis with PICMG 2.1-compliant buses.
-l PCIbus:slot | Its PCI bus and slot location.
-m MACaddr | The MAC address of one of its Ethernet chips. Only valid for boards with Ethernet capability.
-n name | Its board name.

For example, the following command queries for information about the board in PCI bus 1, slot 14:

oamcfg -l 1:14 -q

If you omit a board identification option from the command line, oamcfg performs the specified operation for all boards. For example, the following command queries for information about all boards:

oamcfg -q

To perform an oamcfg operation for a board on a resource host, use the -@ command line option to specify the target host. For example, the following command queries for information about the board in PCI bus 1, slot 14, on resource host IP_3:

oamcfg -@ IP_3 -l 1:14 -q
