Compare that with my 7200 : Input queue: 0/75/19755/291735 (size/max/drops/flushes); Total output drops: 715217 ... Received 23535684 broadcasts, 0 runts, 233 giants, 4480 throttles 568580 input errors, 0 CRC, 0 frame, 396581 overrun, 171629 ignored That's after around 5 weeks of uptime. We had a DoS attack a couple of weeks ago, that might explain the crazy numbers. BTW, it's not memory, neither of my two routers that have the problem are memory constrained nor do they have a lot of routes. > Further, just giving it a clear int when it is running normally doesn't > increment that counter.

Will the EEM applet leave something in your log when it resets the interface? Otherwise, if the auto-heal happens fast enough, you might not know that it kicked in. > BTW, there's also a chance of the switch being involved. I've checked this a couple of times and never found anything. Also, the two routers affected are in wildly disparate environments. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
