Nancy,
Didn't find any URLs, but I think the book Top Down Network
Design would probably cover it pretty well -

Personally, I'd stay away from subnets/VLANs anywhere near that many
devices. Broadcasts can become a problem, as can multicasts. If you
can find a layer 3 switch that'll do IPX, keep your subnets to at most
128 or 256 devices. There'll be no performance loss unlike a
software-based router. And the next time an internet worm comes out,
with small subnets and some protective ACLs preventing workstation to
workstation traffic between VLANs, the downtime will be much less.

Subject: OT:1024 - End users
Hi,
Im looking for a design guidelines in terms of max number of end-users
per segment.
Ex.. in an IP/IPX environment, theoretically speaking we can add up to
1024 nodes on a star topology, is this recommended? What about
broadcast, utilization rate, chatty protocols, etc
Any networks out there, which has more than 500 users per any given
IP/IPX segment? Under what circumstances would I consider adding up to
1024 eusers
Any links, pdf(s)?
Thanks a lot
Nancy
