Not a total solution yet, but I really appreciate your help smicker. I am half the way there.

FROM THE SWITCH,

I can now ping 10.0.0.19, .18, 15 (.19 is my NMS server) Yaaaaaaaaayyyyy !
but not 10.0.0.17 - one of my windows servers ? VERY ODD.

FROM THE NETWORK COMPUTERS,

I can still ping all of the above addresses, .19, .18, .15 AND .17

I can now ping 10.0.0.26 (the interface to my 10.0.0.1 router/modem, the LAN/VLAN gateway).

STILL WONDERING:
-Why can't I ping the loopback of the switch from directly connected computers? I still can't ping my loopback adapter on 10.0.0.240/32.
I am very happy that my NMS server has access to the switch via .26.
- I am puzzled why the interface that is connected to the router/modem/gateway is able to be a path into the network. I guess the router is

acting like all good routers do and routing data to and from itself in both directions, back to my .26 interface on the switch and through the

switch to other devices via their directly connected interfaces.
But since each device is plugged directly into the switch (ex2200-c) it would seem they would be able to directly ping lo0, also.


This solves my big problem of wanting to learn about pulling SNMB info from the switch. THANKS THANKS THANKS
Here is the command I ran on the NMS server and the result I got back:

Command:
./snmp-request -c public -v -2c -Ow 10.0.0.26 .1.3.6.1.2.1.1
