too many errors in some interfaces/cat0s 65000

Hi,

I would like to ask your help for a cat0s 6500 switch which faces some errors on some interfaces..

Some of the logs indicating this situations show:

Have you any idea why i see some many error for those interfaces? Do you know how could i avoid/improve this situation? It seems to be overloaded interfaces..

I would appreciate your feedback.. Any ideas/help are welcome..

best regards,

Re: too many errors in some interfaces/cat0s 65000

Looks like you have a number of speed duplex mismatches between the switchport settings and the nic settings on the pc's or servers . Match both ends for speed/duplex settings , if switchport is set as auto then the nic on the far end has to be auto also , if hardcoded to a specific speed/duplex then the nic has to also be hardcoded to the same setting.

Hi,

Thanks for the feedback. The duplex settings are ok. The mentioned interfaces belong to port channels and i see the messages affect only one of the ports.

Do you have any idea?

Thanks,

I am curious to see your port channels configuration for both devices. In the mid time, here is an interesting link:

Re: too many errors in some interfaces/cat0s 65000

Hi,

Thanks for your time:

From the cisco side (catos). I am just copying some commands for one pair. The messages concern 3/25 as you see.The ports are trunk:

(config is missing)..

set port channel 3/25, 4/34 2

set port speed 3/25, 4/34 100

set port duplex 3/25, 4/34 full

set trunk 3/25, 4 on dot1q

set spantree portcost 3/25 200000 mst

The other side is some juniper which i do not have access...

Any ideas?

Thanks,

Spyros

Re: too many errors in some interfaces/cat0s 65000

If I understand this correctly, you are doing etherchannel between your switch and a juniper device. Right? If so, you should make sure that both sides do agree on the configuration parameters.

It seems also that you also have errors on other interfaces such 3/27 and 3/29. In any case, I am not quite familiar with catos but I do think that the portcost should be between 0 and 65535 but you have it at 200000.

Re: too many errors in some interfaces/cat0s 65000

Hi,

This is an old post from my side but the problem still persists. I still receive those messages with errors as i have described to you..

No etherchannel configuration, no cdp. The sh top (catos) shows for fa3/39 (buffer overflow errors) but the links are not fully utilized. Guys i do not know what else to think...

I put the jumbo frame option in one of the interfaces but the errors are still there.

Please help if you are familiar how to eliminate those errors..

Thanks,

Spyros
