Handy hint for 6500 switches

If you're looking to find out the serial numbers of SFP's installed in your chassis, but can't be bothered to find out by unplugging everything, you can use the following command in IOS. This doesn't include CatOS (it's a different command). Don't forget to no shut your interfaces before checking:

show idprom interface gigabitEthernet 1/1 include Vendor SN

The include part is optional. :)
