I thought that netmon does a status poll when it receives a linkup trap.

I do not think netmon does any status checking on link down/up traps from
the SNMP agent on the device, but it DOES do additional status checking when
it generates its own Interface Down/Up trap. If the device has multiple
interfaces (like a router), netmon will check the other interfaces rather
than waiting for their turn in the polling cycle. This also works with
distributed polling using MLMs.

Subject: Linkdown traps
Hi,
This question has been bugging me for a while. Does Netview
(specifically
netmon) do anything when it receives a linkdown trap from a device
(router,switch..) reporting an interface down? Does Netview/netmon
update
the interface status immediately or it just waits for the next
status
cycle? For example, if my polling interval is 30 minutes and a
router
reports a linkdown trap for an interface five minutes after the last
successful poll. When will Netview present the correct status for
that
interface (right away or 25 minutes later)?
My observation is Netview waits for the next polling cycle and does
not do
any status checking for the linkdown/linkup traps. But I am not
sure about
this. I just want to know for sure what is Netview suppose to do
when it
receives a linkdown/up trap as far as status information goes.
Thanks
Simon Huang
