Well, on the RSP720, the "show interface" byte counters are definitely not every second, though I can't say it's been as long as 9 seconds. I typically look at them while making changes and they definitely stand still for a few seconds.

The 'show interface' counters update at least once a second. Perhaps you are thinking about the rate counters that are often _configured_ to use the last 30 seconds of data to compute the average but also update much more often than every 30 seconds (and default to a 5 minute average). -- Brandon Ross AIM: BrandonNRoss ICQ: 2269442 Skype: brandonross Yahoo: BrandonNRoss
