- Hi All,
-
- We had a MicroVAX II. We upgraded it to VMS 5.4-2. Then we purchased
- an upgrade kit to convert it to a VAX 4000/200. The upgrade kit
- included a new CPU board, memory board, an DSSI disk, and various
- cables and patch panels.
-
- Anyhow, the VAX 4000/200 CPU board has an onboard ethernet port, EZA0.
- I've been trying to get this port working, but haven't been getting
- anywhere. The old DEQNA board still works, but is rumored to be much
- slower than the EZA0 channel.
-
- After I took the ethernet cable off the DEQNA (AUI cable) and attached
- it to the EZA0 port, I would get lots of decnet errors on the console
- like "Circuit up", "Circuit Down", "Adjacency up" There were numbers
- that came with these errors, and I could look them up in the DECNET
- manual if necessary. When I would "set host" out of this machine to
- other machines, the link would be VERY VERY slow, and often freeze up
- for several seconds, as the "circuit up", "circuit down", and "adjacency
- up" errors flasshed by.
-
- I got a new CPU board from DEC, and also replaced all the cables and the
- patch panel. After that, then I couldn't "set host" at all, because
- the destination would always be unavailable. I don't know how the second
- board differed from the first, except that the problem got worse. I also
- no longer get any "circuit up", "circuit down", and "adjacency up" errors.
-
- When I executed a "mcr ncp sho known circuits" it would give me
- circuit state
- isa-0 on - synchronizing
-
-
- When I execute a "mcr ncp sho active lines counters" I would get:
- 433 seconds since last zeroed
- 42 data blocks received
- 42 multicast blocks received
- 0 receive failure
- 3685 bytes received
- 3685 multicast bytes received
- 0 data overrun
- 3 data blocks sent
- 3 multicast blocks sent
- 0 blocks sent, multiple collisions
- 2 blocks sent, single collision
- 0 blocks sent, initially deferred
- 108 bytes sent
- 108 multicast bytes sent
- 83 send failures, including:
- excessive collisions
- carrier check failed
- remote failure to defer
- 1 collision detect check failure
- 0 unrecognized frame destination
- 0 system buffer unavailable
- 0 user boffer unavailable
-
- Anyhow I called Colorado Springs. Colorado Springs sent software patch
- CSCPAT_0252019 which is a new ezdriver.exe. I've installed the patch,
- but the problem is still occuring. After the patch, here is a sample
- of "mcr ncp sho active lines counters"
-
- 1208 seconds since last zeroed
- 1 data blocks received
- 0 multicast blocks received
- 0 receive failure
- 46 bytes received
- 0 multicast bytes received
- 0 data overrun
- 91 data blocks sent
- 70 multicast blocks sent
- 2 blocks sent, multiple collisions
- 2 blocks sent, single collision
- 6 blocks sent, initially deferred
- 3554 bytes sent
- 2523 multicast bytes sent
- 91 send failures, including:
- carrier check failed
- 0 collision detect check failure
- 0 unrecognized frame destination
- 0 system buffer unavailable
- 0 user buffer unavailable
-
- Also, "mcr ncp sho known circuits" now states that isa-0's state is on, and
- not "on -synchronizing".
-
- This is where I am right now. Has anyone ever heard of this problem? I
- actually swapped out the 4000/200 CPU once more since then, but that
- didn't fix the problem either. Each time I install a new board, I
- run sys$manager:netconfig to setup the parameters. I've also swapped
- out the AUI cable and the tranceiver to the backbone.
-
- Any ideas?
-
