Changing network card speed

[Amit Manna_6]

Hi,

Do we need to do

#/sbin/init.d/net stop|start

after we change the speed of network card using lanadmin.

It is not required to restart the network services.

When you change the speed & duplex settings there will be a minor disconnection from the network , the system will be again up and running on the network

Hi,
I don't think you need to do that but if the nfs timeout time is on higher side and you don't have any 100% network dependent application you can do the stop and start.
But it's not mandatory.

No its is not required to stop and start the net services for the effect to take place.
As soon as you change the speed using lanadmin it is straight away reflected.
have a look using
lanadmin -x PPA

Cheers

Changing the speed to 1000 full duplex

# lanadmin -X 1000FD 0

There will be a short delay of about 10 seconds, but the sessions are not lost.

NOT REQUIRED.

No need to restart.

I have been confronted with situations when a channge in speed will sometimes dop the interface for a short period (a few secs max). This is sometimes critical. depending on the system you're working on.

If its a cluster, i strongly recommend you switch the package to another node before you that. But this also depends on your config.

If you change the speed to a forced value, and the port config. from the switch's side is not configured the same, lan interface will drop till they are both matched.

Hi,

it is not needed to stop/start network services.
Just launch

# lanadmin -X 100FD 0

or change 100FD with a supported speed for your network card.

Anyway could you please conclude threads that you launch in a way that future searches on the same problem can have a solution?
I see that you launch several threads but few ones have a solution.

Thanks for you precious collaboration to do ITRC forum more reliable!

Best regards,
