I have a UDP set up to poll a Cisco 4507 switch and display a table that shows the serial number of each module in the switch. It worked fine when I first set it up. Then we had to have one of the modules replaced, and now the table still shows the serial number of the old module. How do I get it to update? I have double-checked to make sure the poller is still assigned. I even removed the poller and added it back with no change.
