Karl,
There are flags in netmon.seed to turn off snmp polling for specific nodes.
It will be better than disabling snmp polling for all nodes as the
Option->Polling does. However you will have to maintain the list of device
in the seed file.
There is also a flag in oid_to_type to disable snmp for devices that have
specific oid. This would allow you to disable snmp only for theses Nortel
devices...

Hi,
Hope someone can help - I've done a bunch of searching but seem to have
got nowhere...
I'm trying to manage some Nortel routers - these are the ones that don't
write the ifOperStatus/ifAdminStatus to the standard MIB (at
all/reliably).
Each router has 3 IP addresses (two frame, one lan). They also have a
backup ISDN interface which kicks in if both frames go down, but this
shares one of the frame IP addresses & since SNMP wont work (above) I
can't use the ISDN dormant bit of the seed file - we can workaround just
checking the IP addresses.
So my plan (which of course could be a bad plan!) is to discover them as
SNMP nodes by putting a $IPaddr entry in the seed file, but then
configure netmon to disable SNMP status polling & only use ICMP polling
against the 3 interfaces that are discovered.
In NT (w2k, NV 7.1.3) I can see under Options->Polling I can set "Poll
all nodes" to "on" and the drop-down to "Disable All SNMP status
polling". This puts a "-E" in the netmon.lrf & updates ovsuf. Will
this mean that any device (even if discovered as an SNMP device) will be
status polled using ICMP?
Also - where is the equivalent setting on a Unix machine? I'm using
Linux with NV 7.1.3 and can see the menu option to turn status polling
on/off, but not one to set status polling to be ICMP rather than SNMP.
Many thanks in advance....
