Re: [Devmon] 10 Gigabit Ethernet Interfaces?

We actually monitor our Po, Port Channels, and then use Network Weathermap
for a view of the bandwidth with our network. A Port Channel is muxing a
number of ports together and if you poll the ifHCSpeed for the Port Channel
it will show you the combined bandwidth of the ports that have been muxed.
So if you have a Port Channel with 4 gig ports in it. Then when you walk
the device and poll the ifHCSpeed for that Port Channel. You will get 4gig
back as the speed of that interface. Port Channeling will also load share
between the interfaces and balance out the traffic on it's own. And if you
loose one or more of the ports out of the Port Channel, depending on how
many ports are in it, you will still have traffic moving through it.
Glad I was able to help you out.

Hello
Works fine, thanks!
I would propose to substitute if_load by if_hcload for
templates/cisco-6506/
templates/cisco-6509/
templates/cisco-7206/
templates/cisco-7300/
At least for those I did it on my server and they seem
to support those OIDs for all interfaces.
BTW, Interfacenames matching /Po[0-9]+/ should be excluded as they are
some kind of channel bundling but do not show the accumulated ifSpeeds
as their own ifSpeed and thus can result in a load of >100%.
bye,
