I have a Cabletron hub that gets deleted within seconds of being
discovered or added via LOADHOSTS.

1. I am running Netview 5.1.1 on Solaris.

2. I have no specific entry in SNMPCONF for the hub.

3. The default SNMPCONF community is public and NODE DOWN DELETE
INTERVAL is 52w.

4. The hub gets loaded and stays, if I don't let it get discovered via
SNMP (Change default community to "junk").

5. Once the Hub is discovered by only ICMP, I then change the SNMPCONF
default community back to public and do a demand poll.  The device goes
through the following events and gets deleted as you can see.   I can
repeat this at will.  It makes no difference if I give it a specific

6.  The oid_to_type is set to H for HUB.

7.  I do know that all the hubs that act this way have the sane agent
code but why does Netview delete them?

SEQUENCE of events...

1.      12:09:53        Node added
2.      12:09:53        Interface decriptor for Lan lan0 changed to "lan0"

13.     12:10:24        Forwarding Status Changed -- Now a Host
14.     12:10:25        Node Deleted
