HP switch with Cacti?

[omergencay]

Dear all,
I have a fresh install of cacti on Windows machine. when I added an HP switch for traffic I got a graph with all the values are "-1.#J". What dows it mean and how can I get the traffic of the ports? I'm using the Cisco router host template.

Thanks.

Is the Cisco template assigning "SNMP - Interface Statistics" data query to the device? Can you post the Verbose info from that data query?
