Hi,
How do I setup the interfaces to use MTU of 1400?
I have been able to add "mtu 1400" to /etc/hostname.XXX and got those NICs
to set mtu to 1400.
However when I bring up the zones, the virtual NICs that get created in the
process, sets the MTU to 1500.
Similarly in Veritas Cluster environment, when I bring up the service group,
the virtual NIC that gets plumbed, also sets MTU to 1500.
Other than running a script to scan each NIC and executing - ifconfig <NIC>
mtu 1400 - is there a way I can set the MTU to 1400 system-wide?
I need this setting for both Solaris 10 and Solaris 9 boxes.
If anybody has any input/suggestion on how to do this, please reply. I
have heard comments on why you are doing it, etc. It is the architect who
has made this decision consulting the network engineers and firewall
experts. Hence I have to do this to meet their specifications :)
Thanks.
