668.0. "DECbridge 620 ERRORS" by VNABRW::PARGFRIEDER () Fri Aug 07 1992 04:47


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 19:10`	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. -Mike Cinnamon
