are you operating any links like this in production today with real traffic? i'd love to see what (if any) CRC/Framing errors you may be recording, some people think that running equipment in this manner significantly compromizes the bit-error-rate of the link. i don't have evidence either way, but "show int x/y" counters would be a great proof point of it not being an issue. cheers, lincoln. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
