This is my main uplink to our provider. and the only one showing any errors at all. It seems my L2 path is clean as tests inside our network run full speed, consistently Its only when we leave the gateway, that we see the errors, L3 The same end points are consistent.... HOST X to HOST Y provides consistent results, with the exception of when we rebooted the router, for some hosts this Inverted the pattern -----Original Message----- From: Jeff Kell [mailto:[email protected]] Sent: Sunday, October 17, 2010 2:39 PM To: Stephan M.

If that's not the case, and no TCAM issues, I'm out of easy answers. I do note you have a lot of hard-coded speed and duplex. In such cases, if the other end is not hardcoded as well, it may have dropped back to half-duplex (typical Cisco default if auto-neg fails). Check "show int count error" and see if anything jumps out at you indicating a duplex mismatch (collisions, FCS errors, etc). Your "speed issues" sound like they are related to the L2 path through the 6500, but not sure why the variance. Is it "always" slow or fast between any two fixed endpoints? between two endpoints at the same sites? Or more generally speaking, are they "slow/fast" on the same interfaces? If not etherchannel-based, are you doing any multiple path selection? (I see no maximum-paths or anything else that would indicate multiple equal-cost routes are a factor).
