All, I am trying to use the snmp OID's in CISCO-ENTITY* to track which ports are in which slots on our routers, so I can use that data at a later stage for provsioning. On a 7200 this works reasonably well, at least I get some faint idea as to what type of card is where. For the 7500 routers however I only get to see that it is a PA in a VIP slot, which is not terribly useful. Has anyone tried this before (and came up with results?) OID used: 1.3.6.1.2.1.47.1.1.1.1 Cheers!
