Netmask problem

Hi All,

Back on the list after a short absence. How's everyone doing?

Started a new job yesterday with some nice new toys so here we go.
I've got a couple of V880s; Solaris 8, soon to be running VCS, Oracle plus
a couple of other bits.
In these V880s there are 2 QFEs. QFE0 and QFE1 are to be used for public
network traffic. 3 and 7 will be used for VCS heartbeat traffic. We're
trying to configure QFE0 and QFE1 onto different subnets.
Lets say QFE0 should have address 10.145.10.192 netmask 255.255.255.0.
Lets say QFE1 should have address 10.213.94.248 netmask 255.255.255.192.

We thought /etc/netmasks should read thus:

10.145.10.0 255.255.255.0
10.213.94.0 255.255.255.192

However this produces an incorrect mask after restart.

Can anyone tell me exactly what I should have in /etc/netmasks to achieve
the appropriate values after reboot.
Currently we end up with QFE1 having an netmask of 255.0.0.0 (ff000000). Our
workaround has been to add a script into the rc3 startup which manually
resets the mask.

I've trolled the archives and not found anything which fits exactly. The
closest scenario didn't have a summary solution posted.
Some interesting arguments too....

Any hints gratefully accepted.

TIA

Joe
