High "Rx Over" Error on a Port

[Bnoba_CEO]

Hi,

I have a port on a switch that is not congesting and the utilization is lower than 20 percent. Yet, Rx over error is so much - can run into millions in minutes:

Port Link Rx Rx Rx Rx Rx Rx Rx
State Crc Over Under Frag Jabber Align Lost
================================================================================
Port> A 0 9757092 0 0 0 0 0
================================================================================

Any advise please.

Jumbo: Enabled, MTU= 9000

Jumbo is enabled.

Bnoba, I'd dig a bit deeper in the jumbo frame configs. The only way I'm aware of you getting this error is for a "receive overrun". Issue a "show port xx info detail" command on the ports in question and make sure they both enabled (you'll see "jumbo:" toward the middle of the list.

Hi Ash,

Thanks for your response. But jumbo frame is enabled on both devices.
