Cisco 64 bit interface counters for 10Gbps interfaces

[ian_couch]

Hello,
We are currently running a demo of Nagios XI and I recently added a few Cisco Routers that have 10Gbps interfaces. The bandwidth statistics are wrong, and I'm aware of the fact that the SNMP reads that are done on those interfaces need to be 64 bit counters in order to reflect accurate statistics. My question is "how is this done in Nagios XI ?" I found a plugin called check_iftraffic42.pl that seems to do this according to it's documentation, but after installing the plugin I'm a little unclear whether this will solve the problem or not and how to actually use the plugin. I'm sure some of this is in the manual or in a 'how to' somewhere, but I just want to make sure I'm going in the right direction before I spend a lot of time on it because I was also wondering if there is a built-in way to deal with this issue, and whether any additional plugins are even necessary.

I found a possible fix here: http://support.nagios.com/forum/viewtop ... counter+64 . I'm going to try this, and will confirm if it works.

Well, I tried this solution, and it appears that snmp version is selectable in the wizard to add the devices, so that is getting done correctly. We are still getting erroneous readings for interface bandwidth though. Is there anything else that we can look at? This still seems to be a 32bit vs. 64bit interface counter problem, but the previously mentioned fix looks to be already implemented.

Thanks in advance for any help.

Ian.

Has anybody come across this?
