Is there a command with which we can get the serial no.s of FXO cards installed in a router (lets say 3640 or 26xx). I have tried using "sh diag" which gives serial no.s as well. But those are not correct ones, because Cisco does not accept these serial nos when we provide them for some contract or RMA. Is there a way to find this information with the help of some command ? Will appreciate the help.
