Hi,

You can change the MTU size online without any impact by using SAM as well as the command #lanadmin -M ppa#

But the changes will last till you reboot the server. To make it permenant you should be added to nddconf file.

Hi Ganesan,

I'm getting below errors.

# lanadmin -M 15000 0
Old MTU Size = 1500
Unable to change MTU size: errno = 22
#

in nddconf file which parameters i need to change.

Hi Again,

I don't think you can set the MTU size other than range between 1501 - 9000.
