I have set up a bunch of terminal server alarms to monitor tx and
rx failures for my customers 74 terminal servers (2 alarms per server).
Each alarm polls once an hour. For the most part, these alarms work
OK. However, of the 148 rules per hour I get anywhere from 1 or 2 to
a dozen or so exceptions of "Can't communicate with target". Yet,
these server are up and running ok. I think the problem has to do with
the speed with which the TS_AM expects the server to respond. Is there
some sort of timer I can adjust to make the AM wait a few milliseconds
longer before it declares an exception.
Using TSM to talk to these server has no problem, but using the
iconic map PM of MCC and querying a given server serveral times in a
row will give an occassional "can't communicate with target".
Though I haven't completely correlated it, most of the servers that
experience this problem are at "remote" sites connect via Vitalink
bridges.
The network is running normally in all other respects. The servers
are DS200, DS300, DS700, and DS90L+.
Thanks,
Richard

I have seen similar "remote" problems with Vitalink bridge console
protocol. Invariably (in my case), there is something happening to the
wire when this happens, ie. an sudden increase in CRC errors, etc. If
the lines are 56kbps or greater, it should be okay as far as timing.

I have looked at the Vitalinks and there doesn't seem to be any
difficulties with line errors.
