I noticed something interesting today regarding the Bandwidth Gauges in the Toolset. Whenever I try to monitor bandwidth on a switch with an '@' symbol in the community string, it fails to poll the device. Switching the string allows it to work again like normal. Problem is, we have hundreds of switches with the '@' symbol in their current community strings, therefore limiting the amount of switches I can monitor bandwidth on.
Is this a bug or am I just using the wrong characters in my strings?
WifiGod - On Cisco and some other devices, the @ symbol designates a VLAN context to retrieve information from (think bridge MIBs).
Search for '@'
