no switch health or port utilization info displayed c2960-24tt device manager
Hi there, I have a WS-C2960-24TT-L. running 12.2(58)SE2
When I connect to this switch's Cisco Device Manager web interface, the "bandwidth used" and "Packet error" both show 0%, and no information appears in the port utilization graph.
The temperature and fan indicators appear to work. The page auto-refreshes. Switchports change color as expected (i.e. go dark when disconnected). I have left the browser open for a reasonable period of time (i.e. over the lunch hour). Other items such as the table of port statistics show up as expected. I am using a secure session. I have tried both Firefox 27.0.1 and Internet Explorer 9.0.25 and see the same result in both browsers.
I am thinking I need to configure something in the switch to enable this information to appear.
