I am hoping to use a microVAX with two DEQNA ethernet interfaces to connect two ethernets together; the microVAX will have full function routing DECNET and will pass decnet messages between the two LANs. I cannot use a bridge in this case, because of incompatibilities between other protocols in use on the two seperate LANs. DEC at Colorado claims this configuration should work; so far I've been unsuccessful. The second DEQNA does not autoconfigure; when I manually connect it with SYSGEN, at the address and vector suggested by DEC at Colo, the system bugchecks with an "unexpected system service exception" in NETACP when I try to set the line state on in NCP. All I've gotten from DEC is "Hm...should work..." Am I missing something obvious???? Howie McCausland Center for Astrophysics 60 Garden St. Cambridge MA. 02138 617-495-7392 HOWIEGP@CFA.BITNET

1. make sure you changed the hardware address on the second deqna by moving jumper W1 over to the second position. The vector is downloaded by the driver, the csr is not. Moving W1 will move the csr from 17774440 to 17774460 which is correct (and fixed.) 2. Make sure W2 is out, and W3 is in... (bus request holdoff enabled, sanity timer disabled) 3. make sure both deqna's are up to rev level e1 (stamped on the magenta handle) 4. watch both deqna's at power up and verify all led's go off. 5. use the configure command in sysgen to find the correct floating vector assignment for xqb.....I wouldn't trust Colorado Springs.... -ed cetron center for engineering design univ of utah cetron@utah-cs.arpa cetron@utahcca.bitnet
