Thanks
1. I can't catch the meaning of the last sentence. Is it mean that the
netview for unix can change the status of the map immediately after
receiving device's trap ( no based on its own polling ). If it can, how can
I set this.
or
speaking in other words
The status will be changed immediately by interpreting device 's trap ,
not by regular polling
2. Sorry, I should explain more clearly. The netview for nt now act as an
attended mlm. When a device's trap arrived, the trap event can only be
displayed in the event browser of the netview for nt. I haven't set any
filter in the mlm. All events received by netview for nt supposed will be
forward to the mlm. And then forward to the central netview. By my
observation, only the trap generated by netview will be forwarded to mlm (
no any trap by other device ).

1. Correct. NetView does nothing with traps from other devices generally.
It
relies on pings and SNMP get. That is why setting your SNMP Configuration
is so
important. Things that NetView monitors (interfaces, nodes, etc) change
status
on the map because netmon tells ovtopmd to change it. In general, base
NetView
would work just fine even if no other agents in the network sent any traps.
This is particularly true in NT. You can use agent traps to change the
status
of items you have added to the map (things that NetView does not monitor)
on
UNIX but not on NT.
2. I believe you have this backwards. MLMs send their traps to NetView.
NetView does not send any back that I am aware of. If you want traps to go
to
the MLM, you can do that, and it can in turn send them on to NetView , and
even
filter which traps get forwarded. Many folks make use of the trap filtering
capability of MLM to keep unwanted traps out of the NetView box.
