877.0. "DigiUNIX's BUG in cut VC ?" by HGOM19::MARKWU () Fri Mar 21 1997 22:05
Hi, colleagues:
I meet a problem in ATM with DigiUNIX 4.0B.
--------| |--------------|
|Server |-------|GigaATM switch|
| 4.0B | |--------------|
--------| | |
| |
Master| |Slave
| |
===================
| DECSwitch 400 |
===================
STEP 1: When i disconnect the master ATM link,
the Slave link will backup the Master link. in the LE-ARP level.
It is say, the ATM-address will change, but the MAC address is
the same. and VC will rebuild.
STEP 2: But if I reconnect the Master link, I can see the Master will
rebuild VC, the slave will disconnect the VC, and LE-ARP have a
replace, the MAC address is not change but the ATM-address will
be replaced by master ATM link.
The strange is in STEP 2, once the slave VC disconnect,
Alpha Server(DigiUNIX 4.0B) will dead, no dump, no any prompt,
the Server's network becames unreachable, the screen looks like locked,
I cann't move mouse, key the keyboard is no use......
So, when I reconnect the master link, I must down the IP in ATM
netcard, wait 1 min. UP the IP in ATM-netcard. NOW it is OK !
I believe it is a software BUG in UNIX. Is it true?
Or I mistake some config ?

| A bug that could cause this behavior was discovered recently. There
should be a patch available by the end of this week.
