How does netmon indentify a "link down" and "link up" trap???  We have Cisco
"Link down" and "Link up" traps that are enterprise(generic ID=6) specific,
can netmon distinguish these as valid "link down" and "link up" traps???  I
don't think so, as we don't see the extra netmon polling getting done as is
suggested in the netmon man page.  I'm wondering if netmon for these "link
down" and "link up" traps just considers traps where the generic ID=2 (link
down) and generic ID=3 (link up)?  If netmon in fact does look at these link
down/up traps and does do the polling that is indicated in the man page, it
would be nice if we(all Netview users) could configure enterprise specific
link down/up traps that could be added into this auto. polling process that
netmon already does have coded, but only for some specific generic ID link
down/up traps.

In the manpage to netmon you can find the following explanation to your
observation:
If netmon receives a link down or link up trap from the trapd daemon,
netmon will immediately ping the interface card identified with that link.
Then it will ping every interface card in that device. You will notice
extra network traffic, therefore, when links are going up and down.
Hope this helps

Thema: Interface down events


How much is the intervals set for Netview polls (pings) for Interface
status on Network Devices. It has to be different from the Status
Polling parameter on SNMP Config. because its 5m on my network but on
the other hand, OV Interface down events seem to be generated in real
time.
