We're in the midst of some network upgrades and are having some difficulties
transitioning to using ethernet Jumbo frames. Several of our older
machines (PowerMac G5's) do not have hardware support for Jumbo frames.
The switch they are connected to allows me to configure frame mtu size
on a per-port basis, but this is not preventing packet drops enough
to allow Rush to work properly. Jobs are taking inordinately long
(which may be due to NFS packet loss caused by jumbo frames) and
I cannot push updated hosts list files to these machines.
If anyone can suggest a solution I'm open to it, though we overall are
having enough issues that we may need to abandon Jumbo frames altogether
until such time as the older equipment is decommissioned.
Thanks,
-Dan
