disabling link down/status syslog messages

Ben Dehner — Mon, 15 Dec 2003 14:11:35 GMT

I have a NIC (10/100) interface in my HPUX 11.0 server which I have disconnected from the network. I am now getting a lot of syslog messages of the form

MII Link Status not OK -- Switch connection at AUI 0/0/0/0
Reset Looper Timeout: DMA timeout ocurrint at 0/0/0/0
...

I know what the problem is -- I disconnected the interface. I don't need it connected any more. How do I disable whatever monitoring daemon is spawing these error messages?

Thanks

Comment out the references to this lan card in /etc/rc.config.d/netconf

Make sure there is no network configuration that references that network. Unplug the network cable and the messages should stop.

if you don't need the network interface any longer, then just diable it. the simplest way is to use SAM. just disable the appropriate interface in the networking section.

I have already used ifconfig to set the interface to 'down' and IP address 0.0.0.0. I have also made these changes to /etc/rc.config.d/netconf. I've even tried "unplumb"ing the interface.

Since the unplugged cable and link loss is a hardware fault, I think STM is generating these messages, because it believes that this device needs to be monitored.

From what I've seen you really have to remove any referance to that nic out of the /etc/rc.config.d/netconf file.

I've even used same to remove an interface, rebooted. And it still trys to do stuff with it. It wasn't until I removed all the info to that card did it ingore it.

I don't think you can just fill it with 0's.

I think I found what's generating error. It is coming from the btlan3 driver bound to this interface in the kernel. (This is the core 10/100 interface.) I'm guessing that I may need to reboot the system and/or apply the latest patch to shut it up. I've tried removing the device with rmsf -H, but it doesn't work, and since the driver is static, I can't remove it from the kernel without a reboot. But since the error is coming from a hardware driver, changing an init file isn't going to stop the error message.

Hi Ben,

Was this I/F ever used by MC/SG?
Would need to gen a new binary w/o this I/F in the ascii file if so.

And check to see if there are any routes set up through that I/F.
Do netstat -in & netstat -rn come back completely clean of this I/F?

I've never come across a situation where a down, an unplumb & removal from netconf didn't do the job. I don't think you should have to remove a driver to stop this.

Rgds,
Jeff

No routes, no MC/SG.

For the time being I shut it up by plugging it back in.
