The error message mentioned in item (ii) below is an indication that the MLM
system has lost connectivity to a node that is collecting SNMP data from.
Make sure that you are running the snmpwalk from the MLM system, and not the
NetView system. Running snmpwalk from the NetView console only checks that
the NetView server has SNMP connectivity. You need to run snmpwalk from the
MLM server to determine if it has SNMP connectivity to the node. Another
possibility is that there was an intermittent timeout, and when you ran the
snmpwalk everything was fine. Check the SNMP configuration either in
NetView or MLM, and make sure that the SNMP retries and timeout are "long
enough" to avoid timeouts on the SNMP get requests.

I don't know the answer to number ( ii ); perhaps someone else does.
If
not, then please open a call with Support.
But ( i ) is the way MLM works. It will only discover nodes on its
own
subnet. You can modify the collection it creates to add some new
nodes or
subnets to the polling it does, but discovery is limited to its own
subnet.
Have you read all the MLM documentation?

Subject: Netview MLM configuration
I'm having some problems with my MLM...
(i) I'm only able to discover nodes in the segment which my MLM is
in.
(ii) For data collection, I get the error indicating that the
"session
to node is currently down" even though I have no problems doing an
snmpwalk from the console to get the MIB variable values.
