Re: [nv-l] SNMP vs ICMP

Hany,

If you are running v7.1 or later, review the /usr/OV/conf/netmon.seed file for further information for controlling node discovery.  As I learned, you need to precede any special line entry (lines prefixed with special character attributes $, !, ^, etc.) with the discovery entry. This means you need to first discovery the node(s) prior to assigning a limiting discovery attribute(s). This will ensure discovery of the node(s), then netmon will create a list of nodes with special discovery attributes and assign them to the node(s) you defined.    

I have edited an example from the netmon.seed file below to describe what I was attempting to explain. The nodes are first discovered, then the attributes are assigned.


SNMP Status Support
#
#      Nodes that have serial interface cards will automatically use SNMP
#      to query for ifAdminStatus and ifOperStatus for ALL interfaces on
#      that node.  Specify other nodes you would like to use SNMP to query
#      for status instead of ICMP pings here.
#
#      Use the prefix '$', and use the same syntax for ranges and wildcards
#      described above for positive seed entries.  For instance,
#
#      1.1.2-10.221-230
#    $1.1.2-10.221-230


Hope this helps,

Ken

Do these commands work in Windows Netview as well?

If you have $ entries in your netmon.seed file then ping should not be 
used (unless an operator uses the Test -> Ping menu).  The way I usually 
check is with the netmon -a commands:
netmon -a 8            shows nodes being status polled with SNMP
netmon -a 12          shows netmon's ping list (if status polls use 
SNMP, the first field should be a very large number)
netmon -a 16          shows netmon's SNMP list

All output is in /usr/OV/log/netmon.trace.

Cheers,
Jane
