link of ports going up and down on 1 single blade

Hello everyone, we have been experiencing some weird problem over the past few days and wanted to get some input from the community,

Monday morning, we started have been experiencing some rolling black outs on blade 4 of our 6506. Users are calling in and reporting that they were momentarily discommended form the network. Sure enough, if we go to the computer, can see in the system event logs event ID generated by the NIC (Broadcom NetXtreme 57xx Gigabit Controller: The network link is down. Check to make sure the network cable is properly connected.) Moments later, the following message will be written to the event logs (Broadcom NetXtreme 57xx Gigabit Controller: Network controller configured for 100Mb full-duplex link.)

A few hours after the first reports, our supervisor engine crashed and rebooted.

Since we have moved every user attached to blade 4 and moved them to access switches and free ports on other blades.

After receiving a replacement SUP on Tuesday, we have slowly started to move users back onto blade 4 and we are still experiencing some port disconnecting.

At this point, I should we replace the blade?

Here is a show modules outputs

Re: link of ports going up and down on 1 single blade


1) do you get any console messages when this happens?

2) If you have configured syslog, can you check those syslog messages?

Personally, if i were you, I would again talk to the cisco accounts representative and/or open a TAC Case to find the root cause.

Re: link of ports going up and down on 1 single blade

Thanks for your post. I have a crash details but no syslog.

I will configure syslog now and gather more details.
