| It sounds very much like you have not completely shut down the all
the protocols using that MAC address, and you have duplicate MAC
addresses on both interfaces. Look at the interfaces and check the MAC
address. If it's the same, then shut down the network on the ethernet
interface and see which protocols are still active on that interface.

| P.S. Did you shut down LAT, for example?
|
1459.3 | LAT & Decnet were stopped... | NWD002::GOODELL_MA | Marianne Goodell 801-565-3174 | Thu Sep 29 1994 16:22 | 10 |
| Yes. I got more of the story... Another Digital consultant came
on-site last week, rebooted the systems and had commented out LAT
and DECNET in the system startup file. He then turned on the FDDI
controller and started them both up manually.
Any more ideas? Also, excuse my ignorance, but how do we check the
MAC address to see if it's duplicate on the interfaces?
Thanks,
Marianne

| ...assuming VMS from your previous comments:
1) run SDA ($ Ana/sys
2) Show lan/dev=(device)
...you will eventually get to a screen something like:

1459.5 | May have to purge and clear Ethernet line and circuit | SSDEVO::PARRIS | RAID-5 vs. RAID-1: n+1 << 2n, in $$$ | Thu Sep 29 1994 20:23 | 11 |
| > -- define circ and line states off for the ethernet controller
> -- define circ and line states ON for the FDDI controller
Should probably be:
-- purge and clear circ and line info for the ethernet controller
-- define and set circ and line info for the FDDI controller
I've seen reports that DECnet will change the address of a LAN controller from
the 08-00-2B-* form to the AA-00-04-* form when it starts up, even if the line
and circuit state are off, and that you need to purge and clear the info in
DECnet before it will leave it alone.

1459.6 | Bad controller :( | NWD002::GOODELL_MA | Marianne Goodell 801-565-3174 | Wed Nov 09 1994 12:23 | 7 |
| It finally ended up being *another* bad FDDI controller in the VAX. We
were doing most of the things recommended in this note at one time or
another with no success. Finally, we tried a new controller and we're
running on our FDDI now.
Thanks for all of your help.
