mtu for Default route

[suresh_6]

Hi,

When We change MTU from 1500 to 1400 on Server NIC do we also have to change MTU for the Default Gateway.


Thanks in Advance.

Hi

I don't think U need to change MTU of default gateway. Because MTU is the Maximum Transmission unit of ur lan interface. Better U run this command

#lanadmin -R "NMID"

This will set the mtu size to the default for that link type.

Best of luck

Hi
The MTU of your gateway nothing to do with MTU of the system. the system will contact thru the gateway. gateway's MTU will be more or equal to the MTU of the other system .
You can change the MTU of the gateway using SAM (if it is HP m/c) SAM-->Networking and Communication--> NIC-->Action-->Advanced options-->MTU.

Thanks to Shahul and Ravi

It was set to 1400 on the out side of the firewall(our default gateway) and Also My local Lan says it should be 1500 .In this case Shall I have to change 1500 on the Server NIC and 1400 on the Default Gateway or change 1400 on both of them.



Thanks again

Suresh
