Link Timeout on internal port

Hi,
we have IBM 2499-192,(Brocade DCX-4S Backbone)Switch. we are getting these errors very ferquently in errdump.

Re: Link Timeout on internal port

Hi,

the Message Reference guide tells us:

Indicates that above normal errors are observed in the hardware that may or may not impact the data traffic.

Whenever this error is observed persistently, power cycle the faulted blade. If the problem persists, replace the blade.

I had the same messages on FOS 6.4.2b and opened a support case and got and advice back to run a specific command which enables port resets on creit recovery lost detection. I am sorry I can't post the command here because I have currently no access to my KB.

I would suggest that you open a case to get this information.

Regards,

Andreas

Re: Link Timeout on internal port

Hi,

It seems that there is an internal connetivity issue in the backend ports that connects port blade in slot 1 with Core Blade in slot 6

2012/02/29-20:01:13, , 335, SLOT 5 | CHASSIS, WARNING, IBM_2499_192,  S1,P-1(1): Link Timeout on internal port  ftx=-844227415 tov=2000 (>1000) vc_no=5 crd(s)lost=3 complete_loss:1

since the switch's running FOS v6.4.2a, before starting reseating/replacing blades you should try to enable bottleneck monitor for the backend ports by executing:

bottleneckmon --enable -alert

bottleneckmon --cfgcredittools -intport -recover onLrOnly

(take a look at the command ref manual for further info about these commands)

If these events doesn't end by enabling bottleneck monitor on the Backend ports, you will have to reseat the Core blade in slot 6, and if these events reappear, do the same with Core Blade in slot 6. If there's no luck, I suppose that you'll have to start thinking in replacing these bladed.

Since this is not a trivial operative, I recommend you to open a ticket with your service provider.

We had similar problem due to temperature (the FAN cooler were in error) in IT center
