High utilization incorrectly reported on Tunnel interface

[brianhill88]

Hello,

I'm getting high utilization alerts on a tunnel interface. It appears that Ciscoworks thinks the line is only capable of 1 Mb/s. That only thing that seems to make sense is that Ciscoworks is getting that line speed from the bandwidth parameter on the interface, although I've only ever used the bandwidth parameter for altering routing. Before I start altering that parameter I wanted to confirm that is indeed the case.

Thanks

That is correct. SNMP gets the interface speed from the bandwidth statement. DFM uses ifSpeed in its utilization calculations. See this thread for more details:

Thank you.

Sorry, the one time I don't search the forums before I post a message is the time when someone just asked the same question 5 days ago. = )
