- Oh, probably. We haven't benched it, but we've got about half of our 40
- zones on campus running off Netware servers (3.11). But I can't see why
- it would load things up any more than the other 20 zones that are hiding
- behind KFP/SFP's, Gatorboxen, and such.

- They don't. However, the way Netware is put together *logically* and
- *internally* (under ODI), the o/s counts as it's own internal-to-the-
- machine-network (which is why each netware server has an 'internal network
- number), which routes to each logical/physical interface. Netware, by
- nature, routes. It can't help it. It's designed that way. To show this
- in poor character graphics, a netware server, of itself, might look
- something like this:
-
- --------------------------------- The Server is like
- | | | a router box...
- | | |
- | | + board A is bound to IPX and ATK
- | |
- | + board B is bound to IP and IPX and ATK
- |
- + board C is bound to IPX
-
- The server is routing IPX on three interfaces, IP on one, and Appletalk
- on two. Even if you only have *one* interface board in the server, you
- must still run some level of routing for each protocol you bind to an
- interface, since that is the layer that the 'internal network' talks
- to a bound interface.

- I know there is SNMP that runs under netware, but I'm not sure what it
- has as a level of service (i.e. does it control routing characteristics?
- does it report on nodes that don't run on smtp on server-local inter-
- faces?...) You might find it more profitable to ask this question
- particularly on comp.sys.novell.
-
- Good luck!
