IOS CLI historical interface graphs

I was researching something for a project recently and came across a feature I hadn’t seen before:  historical interface graphs.

With this feature, you can enable up to 72 hours of traffic statistics on your interfaces, and you can view this data via the CLI, similar to how ‘show proc cpu history’ works.

Check it out:

Interface-history-cli

I’d never seen this before, so I was quite excited. If you’re like me, and haven’t tried this out yet, here is how you configure it:

interface Gig0/0
    history {bps | pps} [filter]

The filter can include a lot of different items, including:

  • input-drops
  • input-error
  • output-drops
  • output-errors
  • overruns
  • pause-input
  • pause-output
  • crcs

and the list goes on. You can see a full table of supported filters in the IOS Command reference.  I found this worked on my 7200s, ASR1Ks, ISRs.
