Interface errors

[zeeshanparkar]

I have a Cisco 6509 interface connected to an Avaya CLAN. Both are set to 10/ half duplex. But there are errors incrementing on its interface. Why is it happening. Someone at work told me its because both are half duplex but I don't buy that arguement. Can someone please explain this in a better way to me.

249 runts, 0 giants, 0 throttles

249 input errors, 249 CRC, 0 frame, 0 overrun, 0 ignored

but due to the half duplex I have to live with it?

That's right.  And maybe you'll need to "live with it" in regards to the 6500 logs could and may annoying spit out "duplex mismatch errors" all the time.
