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:

Hostname

Model

Junos release

“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:

Item

Version

Part Number (helpful for putting in orders for replacement parts)

Serial Number (hooray!!!)

Description

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.
