_ DEC-O-LOG for DEBET

_ DOL, DEBET-I001, ETHERNET NOV 87

PROBLEM: This FCO corrects problems seen on nodes running
RBMS as well as rectifying several other minor microcode
problems (see problems description for more details). It
also enables a down line loading required to support LAN
traffic monitoring. 

FIELD EFFECTIVITY: Rework all DEBET-AA, AB, RC, RD, at
Revision Level D7 or below for customers experiencing
problems running RBMS.  This FCO implements ECO
number 54-17521-MK007 and DEBET-MK011. 

QUICK CHECK: 1.The unit tag location on the rear of the 
unit will have Revision Level at "E7".  2. Opening up
the unit will reveal that: E131 has a ROM marked
23-293E5, and E132 has a ROM marked 23-294E5.

_ DOL, DEBET-F002, Ethernet LAN Bridge, FEB 90

PROBLEM: This FCO corrects the following problems: 1.)Broadcast 
address not being passed through bridge when Apple's/Mac's are 
installed on the network.  2.)Line cost parameter is not saved
through a reset.  3.)Bridge fails upon receipt of bad RBMS messages.
4.)Bridge fails to respond after continuous receipt of RBMS read
bridge message.  5.)Bridge considers miss_error from the lance to
be fatal.  6.)Bridge returns an error message when trying to add or
set a learned address.  7.) Bridge fails to re-pick random SYS ID 
interval.  8.)Raising the link cost of the InLink to go into backup
mode.  9.) Setting of address on the bridge by RBMS command line
"ADD FOR PHY ADD XX.......ZZ LINE fails.

FIELD EFFECTIVITY: Rework "as needed" DEBET-AA, AB, RH and RJ below
Revision "J7" and DEBET-RC and RD below Revision "F8" for customers
experiencing problems as noted in the Problem/Symptom Section of
this FCO Document. This FCO accomplishes an upgrade from DEBET LAN
Bridge 100 to DEBET LAN Bridge 150 for DAS Customers.

QUICK CHECK: 1.) The unit tage located on the rear of the DEBET-AA,
AB, RH and RJ will have Rev. level at or above "J7".  The unit tag
located on the rear of the DEBET-RC and DEBET-RD will have Rev. level
at or above "F8".  2.) Execute the RBMS (Remote Bridge Management
Software) command "ADD FOR PHY ADD XX.......ZZ 2", successfully.

_ DOL, DEBET-F003 Microcode Upgrade Aug 92

PROBLEM:  This FCO corrects the following problems: 

1. HELLO messages with a SNAP header were treated as a regular HELLO message 
   and processed incorrectly.  
2. The LB150 was responding incorrectly to the all-bridge-multicast address 
   (the response packets would have the wrong source address). 
3. Address filtering on addresses of the form FF-FF-FF-FF-xx-xx (where the first
   4 bytes are FF) are not handled correctly once the bridge is rebooted).  
4. The "second operating" counter would drift 24 minutes and 48 seconds ahead 
   every day the bridge is operating.  
5. No-frame-interval is implemented in the LB150.  If no packets are received 
   for 5 minutes, on either port, then a loopback packet test is run on the 
   LANCE for that port.  If  the test fails, the LB150 into self-test.  If the 
   test passes, the LANCE is initialized again and the bridge operation 
   continues.  Furthermore..  If COLLISION LIMIT EXCEEDED gets incremented 5 
   consecutive times in a row, run the Quick Test on the LANCE.  
6. If the bridge is running in IEEE mode and it's in backup mode (in parallel 
   with another bridge), it would sometimes receive a packet on Port B and 
   transmit it out on Port A.  
7. The RBMS/ELMS command INIT WITH DEFAULTS will cause the power-up counter to 
   be equal to -1 (65535) when the LB150 comes back up.  
8. TCN messages go out every 9 minutes 50 seconds from backup bridge when in 
   IEEE mode.  
9. LB150 no longer forwards oversized packets (greater than 1518 bytes).  
10. Invalid_message counter was being incremented incorrectly by firmware.  
11. Receiver Overrun/System Buffer Unavailable/Unsolicited  Reset (RO/SBU/UR).

FIELD EFFECTIVITY:  Rework "as needed" DEBET LAN BRIDGE 150 models, DEBET-AC, 
DEBET-AD, DEBET-RP, DEBET-RQ, DEBET-AU, DEBET-AG, DEBET-RU, DEBET-RG, DEBET-AK 
and DEBET-RK at and below Revision Level "D01" for Customer experiencing 
problems as noted in the Problem/Symptom Section of the FCO document.  This 
FCO implements ECO numbers 5417521-TWO015 and DEBET-TWO021.

SOLUTION: Replacement of ROM's located at locations E131 and E132 with those 
supplied in this FCO EQ Kit, number EQ-01646-01.

QUICK CHECK:  This unit tag located at the rear of the DEBET-AC, DEBET-AD, 
DEBET-RP, DEBET-RQ, DEBET-AU, DEBET-AG, DEET-RU, DEBET-RG, DEBET-AK.  

1. Invoke ELMS (Extended LAN Management Software) by typing ELMS at the DCL 
   ($) prompt.  
2. Issue the command, USE BRIDGE "BRIDGE NAME or PHYSICAL ADDRESS" at the 
   ELMS prompt.  
3. Issue the command SHOW "BRIDGE NAME or PHYSICAL ADDRESS" CHARACTERISTICS at 
   the ELMS prompt.  
4. Examine the software version field.  The value should be V1.4 or higher.

The DEC onsite labor charge will be the time required to install and test the 
FCO at the then current hourly rate.
