This is a interesting but a trivial post. Everybody know about the interface command “load-interval” that changes the time period over which the interface packet-rate and throughput statistics are averaged.
I discovered an addition to this command on the Nexus the other day while poking around. NX-OS allows multiple counter intervals to be configured on the same interface. This allows different sampled intervals to be listed at the same time.
The configuration is easy:
#interface Ethernet1/19 load-interval counter 1 40 load-interval counter 2 60 load-interval counter 3 180
The above commands sets the first interval, also the default interval to 40 seconds, the 2nd to 60 seconds and the 3rd to 180 seconds. Now have a look at the highlighted output below :

Thank you veru much for this information. The Nexus has so many commands and unless you use them on a daily basis it is possible to overlook some of the imporatnt ones.
Very interesting. I’m now wondering which of these multiple values that Solarwinds is picking up via SNMP!
