Checking DRAM To check how much DRAM you have installed on the switch or bridge/router, on the NMS use:

bcmuname -M <device>

Where <device> is the IP address or hostname of the switch or bridge/router.

Checking Flash Memory To check how much flash memory you have installed on the switch or bridge/router, on the NMS use:

bcmdf <device>[:<drive:>]

Where <device> is the hostname or the IP address of the switch or bridge/router.

Specify drive A for NETBuilder II bridge/routers or PathBuilder switches.

Do not specify a drive for SuperStack II or OfficeConnect bridge/routers.
