Jane,
Thanks for that, but just to confirm what you are saying that to icmp
poll an snmp device with a single address I'd need the following in the
seed (based on testing against NT machines - this isn't the real Nortel
oid);
$10.1.64-68.254 # Router range should be SNMP - the effect of the next
line will mean
# they will have isSNMPSupported=TRUE, so will
SNMP config poll but
# will icmp status poll.
^@1.3.6.1.4.1.311.1.1.3.1.2 # icmp poll any w2k machines no matter
what the ip addr
10.1.64.254 # Something to hurry up discovery
In live each router has 3 ip addresses, I'm assuming that I will need to
include these within the SNMP range ($), that the Oid statement will
make them icmp polling (^@) if they are Nortel and that I will only
need 1 address (the lan side .254) to encourange discovery. My thought
is that the configuration poll will find the other 2 ip addresses for
this device? Also, since the router is SNMP config polled, netmon will
use it to find devices on it's local network?
Per node/Per interface.... These routers have 3 interfaces which has ip
addresses - will this remove this issue provided I used the seed config
above since this will cover all addresses the device has & all devices
of that oid type...
Many thanks
Karl

Subject: Re: [nv-l] snmp/icmp polling
Hi Karl,
I think part of your answer is to use the ^ (caret) symbol. If you
have, for example $10.1.2.* but want to ping-poll some of those devices
(eg. 10.1.2.3) then put ^10.1.2.3 in the seedfile.
I'm not at all sure that that is going to give you the result you want
though. I had a feeling that the ping-polling / snmp-polling was
determined on a per-node basis, not on a per-interface - anyone confirm
that?
The $ syntax in the seedfile doesn't actually affect discovery - that is
fundamentally done by a response to a ping. The $ entries simply say
"once this node is discovered, use SNMP to status poll". Cheers, Jane
