I don't have a 12000 here to test with, but I've seen issues like this even between 6509s on occasion, so you're not alone :) A few questions: 1. What is the distance between the devices? 2. What type(s) of GBICs or SFPs are you using? 3. Are you using singlemode or multimode cables? > The throughput between the two pairs is also terribly slow. Most likely due to data being retransmitted when a packet doesn't come across the wire correctly. > We have tried different cards in the GSRs, we have tried different > fiber cables. Have you replaced the GBICs/SFPs on the 6500? Also, look at a show interface XXX from both sides of the link - do they both show the same speed and duplex? I've seen funky issues in the past where gig ports would try to run at speeds other than 1000/full. jms _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
