The .com file look like below (only 2 lines);
@sys$manager:tcpip$define_commands.com
ifconfig we0 ipmtu 1498
Did I do something wrong?
Thanks

Re: Changing MTU on TCPIP network
Was this done before or after starting TCPIP? I think to make it work, you would need to execute the command BEFORE starting the interface (or stopping and starting the interface after setting the value)
However, the question arises - why? With current versions of TCPIP, you're much better off letting Path MTU Discovery work it out for you.

Re: Changing MTU on TCPIP network
This file is the right one for modifications of Tcpip before starting, for example
$ @sys$startup:tcpip$define_commmands
$ sysconfig -r inet tcp_msl=32
(this is only an example !)

Re: Changing MTU on TCPIP network
Because of the router/juniper that I have to connect, right now support only MTU size 1498 or smaller. This for temp solution until upgrade the new version of that equipment.
Once I see the mtu didn't change, I can sign on SYSTEM account and call manually. It means I can change it after TCPIP started.
Dear Gerard,
I should use command
sysconfig -r inet tcp_msl=32
instead of
ifconfig we0 ipmtu 1498
Please advise
Thanks

Solutionfirst I seond the suggestion to create
sys$startup:tcpip$systartup.com and place your
commands in there. This is the supported way of changing IP settings and ensures the commands are executed at the appropriate time.
Second, your command "ifconfig we0 ipmtu 1498"
is correct, Gerard was just giving an example of what he has in his startup file.
Greetings, Martin
