We are having problems switching an Ethernet on a DELNI onto a real Ethernet cable. The situation is like this: We have two 4.2BSD VAXes with Interlan controllers (and now the 11/73 with a DEQNA) on a DELNI. They all seem to be fine. However, as soon as I switch the DELNI onto a real Ethernet cable, everything stops working. As far as I know, that DELNI has never worked on a real cable. Any tricks ? A possibly clue: it doesn't matter whether I attach a transceiver cable to the DELNI or not - as soon as I flick that switch on the DELNI, transceiver or no, the net stops working. Any help would be appreciated. Thanks. Cheers, Dan Ts'o Dept. Neurobiology Rockefeller Univ. 1230 York Ave. NY, NY 10021 212-570-7671 ...cmcl2!rna!dan rna!dan@cmcl2.arpa

It seems not acceptable to mix Interlan and DEC (DEUNA or DEQNA) on the same DELNI, unless the DELNI is stand-alone. For the moment we have fixed it by putting DEC on one DEUNA and Interlan on a different one: seems better. The problem is quite likely that the Interlan controllers are Ethernet 1.0 specs (at least, ours are). We shall do more tests in a week or so, to find the exact cause.

We've a DEUNA, Interlan's and 3Com's on two DELNIs (in cascade with one of them on Ethernet, which according to the specs is not allowed...) It's all working just fine. The Interlans are Eth.2 spec, the 3Coms are Eth.1. However, another 3Com, when connected to the DELNI, screws up the whole net. Put it on an Eth.1 transceiver and it's ok. Matter of luck... In general don't connect Eth.1 stuff to DELNIs. -- Piet Beertema, CWI, Amsterdam (piet@mcvax.UUCP)
