Dear All,
Since installing NetView (7.1.4 FP 3 on AIX 5.2) I have notice that
trapd.log has been getting fairly well sprinkled with Node/Interface Up/Down
messages. I finally got around to trying to get to the bottom of it.
If I pick on a particular node (in this case a Windows server), I was seeing
Interface & Node Down messages followed five minutes later by Interface &
Node Up messages. I changed the default polling interval to ten minutes and,
as you might have guessed, the same entries cycle through trapd.log, but
only half as often.
Having located the node on the GUI, I did repeated Demand Polls on it. They
just alternate each time between up and down. A large number of nodes are
similarly affected but by no means all.
Has anyone got any idea what's happening?
Thanks in advance.
Rob Brinkworth.
