An etherchannel link between 2 Catalyst 6509 with IOS 12.2(18)SXE5 the interfaces have overrun frames. The connection is done with 4 ports 1G of WS-6548-GE-TX modules installed in every of any 6509. Â¿Do you know how can solve these overrun frames?
I`ve attached a file with the config of all interfaces and the sh interface output messages.
Thanks a lot.
I would monitor the interfaces for a few days before adjusting the input queues on the switch. Based on the output from your original post the statistics show that the amount of drops are not that high with the amount of traffic over a two week period. It would be advisable to clear the counters and monitor the amount of drops every few hours and during peak traffic patterns.
I have had to adjust queues a couple of times in the past (and no expert by any means on the subject). After determining that there is a problem with drops I would incrementally increase the queue size on the interfaces while still monitoring the statistics. You should find a number that will significantly reduce the amount of input drops.
Right now your input queues are set at 2000. I would start increasing them by 100 until you are satisfied with the results without jacking them too high. I also don't think it matters whether the ports configured as layer 2 or 3. Here's how to increase the the input queues.
