Hi folks! I have troubles with a DECbridge 620. The bridge resets itself and the "unsolicited reset" counter increases. This is a fatal problem for the customer, because the Cluster sattelites are crashing. (selftest + preforw. state takes approx. 1.20 min) We have changed all modules except backplane, but still the same. My question now, which errors (bridge- or network problems) can cause these "unsolicited resets"? thanks in advance for any help Alf

| 668.1 | Make sure you are running v1.2 firmware | QUIVER::CINNAMON | Fri Aug 14 1992 18:10 | 33 | |
| Alf,
This sounds very serious. First check to make sure you are running V1.2
firmware. There were a number of things in prior releases that could cause the 
bridge to crash which would be reflected in the 'unsolicited reset' counter.
Here is a list: 
Version 1.2 Corrections
-----------------------
DECbridge 600 Series Only
-------------------------
Symptom:        Bridge crashes periodically.
Problem:        Firmware executes bug check if it sees the silo overflow
                bit set in the LANCE receive ring descriptor.
Correction:     Bridge does not crash but counts the error and remains
                operational.
Symptom:        Bridge crashes periodically.
Problem:        Firmware executes bug check if the LANCE CSR has the
                babble bit set.
Correction:     Bridge does not crash but counts the error and remains
                operational.
Symptom:        Bridge crashes when accessed through the IP protocol (example
                SNMP requests and pings).
Problem:        ARP messages received causes a crash if the bridge
                obtained IP address via BootP protocol.
Correction:     Bug fixed.  Bridge will not crash on receipt of ARP messages.
