We need a little help on tracking down a ? LAN ? problem that a DECNIS 600
is reporting. This past weekend a DEChub 900 was install and three 600's were
connected to it and configured to be behind a bridge port (seperate LAN
for the 600's). Today bridging response between the site with the routers
and a remote site with systems was either jerky or disconnects were occuring
at a fairly rapid pace. We found that the DECnis was reporting Unavailable
Station Buffers at a fairly rapid pase. Re-arranging some of the configuration
on the 900 helped alleviate the jerky response and the disconnects but the
Unavailable Station Buffers are still occuring at about 12 per second. This is
after prime time and the CSMA-CD station is reporting less than 200 PDU's
per second.
I have looked in the log files and do not see any events concerning CSMA-CD
devices but the system could have rolled over and quit logging with that
level of errors being reported.
Any ideas on what to look at, the router is on the network and can be quired.
Note: it;s currently running 2.3.14 and as soon as we can get a CLD worked
we will be upgrading to 3.1.9 or 4.0.2.

Hi Rod, We believe that you are suffering from a multicast forwarding problem that we have already fixed. This fix was contained in the V3.1-8 fix kit release. There is no V2.3 fix available for this problem. For us to confirm this we would need a dump from SCHNS1. Cheers Tony. | |||||
| 3531.2 | Upgrade Planned - need help on pushing for it now | SCASS1::ROCHELEAU | Rod Rocheleau - 972-527-2272 | Tue Feb 04 1997 08:44 | 13 |

Tony,
Could the problem that was fixed come up suddendly after a LAN
re-configuration? I can execute a dump this evening but time
would be better spent upgrading to 3.1.9 if we can document
the unavailable station buffer problem.
Rod

Upgrading to x3.1.9 corrected the problem. Unavailable Station Buffers has stopped increamenting. Thanks Rod | |||||
