Kind of a simple one here that you could totally figure out on your own, but I had forgotten to write down the serial numbers on some gear that I put in a remote office.
“show version” will get you:
“show version detail” will get you the above and a bunch of other release and build numbers for software.
“show chassis hardware” is what I was looking for. For each piece of hardware in there:
Part Number (helpful for putting in orders for replacement parts)
Serial Number (hooray!!!)
Simple, I know. But some people may not look under chassis commands for serial numbers. I know it wasn’t my first instinct.
Oh, and on Foundry FCX-24GS (at least) it’s “show version” to get the serial number. Hope that helps a bit too.
