Has anyone run across a MIB or a combination of MIBs that provides the MAC address that is stuck in a port on a 4500 series switch when port security has been enabled. I'm using non cisco monitoring software that enables the collection and display of the information on a web page, just need to find the right MIB. I've tried several of the most likely MIBs but they're either deprecated or don't return a value. I have run a test with standalone software from the same manufacturer that doesn't use the webpage feature and received accurate results. This makes me believe that the data collection is enabled on the switch. Thanks for any help!
