Does "rate severity" add context to the value from interface counter?

When one is looking at interface counters, does "rate severity" provide context for the "value"?

Since in some cases 1000 drops is not a big deal while others it may be.

Those are actually two different fields.

Rate is the number of packets per second for the duration you've run.

So if you run the counter command after 5 seconds and the total number of counters is 1000, then your rate would be 200 (1000/5 seconds).

Severity is the type of counter: flow, drop, error, info, etc.

In your example, the first counter has 27215 as the value, 0 as the rate (none incremented since the last time the counters were displayed) and drop is the severity. Same explanation for the 2nd counter.

Hope this helps,

Greg

Thanks, that makes sense. I knew you could see the difference in counters from each time it was checked with

> show counter global filter severity drop

> show counter global filter delta yes severity drop

But I didn't know the "rate" was tied to that as well.

Thanks.
