The CPU may be freaking out as interfaces and routing protocols think as errors stack up quickly the link is flapping, causing a lot of SPF calculations or BGP table re-syncs. Once the errors die off the interfaces appear stable.
With both interfaces receiving the same garbled packets, it's unlikely a set of optics have gone bad and impacted both the transmitter and receivers. So it sounds like you have dirty patch interfaces or a mangled patch cable. Clean each with >95% isopropyl alcohol and lint-free wipes and/or replace the patch cable(s). If that doesn't clear it up, swap GBICs. Are you using newer 1300nm GBICs with older 62.5/125um patch cables? -D ++++++++++++++++++++++++++++++++++++ We have a 7206 that is getting lots of input errors and overrun errors on the LAN side without CRC errors. On the WAN side we are getting all 3 but on a much smaller scale. Every couple of weeks the CPU goes through the roof but the box has never rebooted. Can anyone give me a detailed breakdown of what I should be looking for here? _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
