To
assure polling with SNMP rather than ICMP you must have the "$"

ICMP
There is one point of clarification - if you do discovery
without the "$" sign - NetView will discover using SNMP (assuming community
access) but that is not the same as polling with SNMP. To assure polling with
SNMP rather than SNMP you must have the "$" sign in netmon.seed.Otherwise netmon
will discover with SNMP and then poll with ICMP.

In theory, you should not need to have entries in the seedfile
for
active discovery, as well as $ entries. Provided automatic
discovery is
turned on then the discovery algorithm should find things
eventually
unless entries in the seedfile prevent discovery.
However,
once you have any wildcard in your seedfile (* ? - ) then the
seedfile
will PREVENT discovery of anything that is not specified
explicitly or in a
range. I guess it depends on your policy for your
seedfile. As
soon as you have any wildcards in your seedfile, then
Ken's example is the
way to go.
Cheers,
Jane
