I have a question about which IOS and CatOS allow for the device/chassis serial numbers to be displayed when specific "show" commands are executed. I think I read or heard that some of the newer IOS versions will be programmed to include info such as the chassis serial number. I think older versions of IOS had to have the "snmp-server chassis-id <serial #>" configured in order to display the chassis serial #.
Does anybody have any info for this?
Thanks in advance.
