You can adjust some of the SRR queueing parameters. Look in the list archive for details on the 3560, which has similar problems that have been discussed extensively. Or get another switch. :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
