I brought the adjacent ports in IP gear down and up. We could verify
from management interface to the lucent that autonegotiation wasn't
performed after down/up, while we could observe before down/up that
autonegotiation was marked being done even though we had configure
cisoc interfaces as 'force-up'. So clearly it needed to see link
down/up.
We didn't powercycle lucent, as it would mean bringing down tens
of 10G waves. But taking the GBE module out/in would have been
option (three countries are involved, so bit inconvenient, but
possible). Country A - Country B is one lucent leg.
Country B - Country C is another lucent leg.
Anyhow thanks for the thoughts, any help I can get is much
appreciated :). Of course we have full support agreement
to both vendors, which we probably have to try sooner
or later, but it'll be long battle on who's problem it
really is.
