Re: rxTotalDrops

Provide more information. I.e. show interface Fa1/0/1

Rx Drops can be either the result of a congested receive buffer or physical media problems on the far end.

What type of cabling is in place? The distance and if applicalble transceiver type.

Re: rxTotalDrops

Thanks for your respond Leon. I am using the fiber cable from one closet to another about 50Meter apart. These are gbic ports. As you can see I have no error on both ends. Check the following details:-

Re: rxTotalDrops

I found the following explanation for rxTotalDrops in the documentation for Cisco 6500.

"The rxTotalDrops field includes these counters:

* Number of bad packets because of a CRC error, a coding violation, or a sequence error.

* Number of CBL blocking drops.

* Number of instances of invalid encapsulation.

* Number of broadcast suppression drops.

* Number of drops because the packet length is less than 64 or greater than 1518."

Re: rxTotalDrops

Thanks again. I found the similar information on the output interpreter, followed what they recommended with no luck. My ports are running clean with no errors except for this rxTotalDrops.

Phil.
