Sammi,
if it was me ( and yes an cisco co`s in the uk i AM looking for a network
designers role)
first i would chuck your 2900`s and put in 3548xl`s ..( if you havent
already bought them)
also i take it (silly question) that you have LINE Of SIGHT for your
aironets???? and that also you are aware of any enviromental issues (such as
mobile phone towers/power stations)that are close-by...
There no point in responding if you have ...this is just a general reminder
as for dhcp .... i never put my servers on dhcp ....to-many complications
also you seem to have gone for the distributed server model ....
Where will you Domain server`s be .....will all the server be domain
server`s or will some be app only....
think about the replication traffic between the servers in each vlan (i
presume hut)
also the more vlans for server`s you have ...the more switching that needs
to be done .....make sure MLS is enabled on your G.....
also are you sure arionet can handle the amount of traffic .....can you get
some kit and build a mini-lab first...?????
sorry i can`t seem to get your diag ....which would really help to look at
sorry but thinking some more about this i want to know why you have so many
Vlan`s
Hmmmm........
i really need to look at your diag ...can yo u post it 2 me ....
so i can have a good look
cheers steve
(oh BTW i am a desinger now ...it`s just i want a better job ,that all )
steve
also you are aware of the enviromental

>We are migrating off of Banyan to Windows 2000 in late July and

>I have 95% of my hardware:
>
>Dell Poweredge servers:
>1550 (6) - file servers
>6450 (2) - SQL and Exchange servers
>2450 (1) - SQL
>
>Cisco Switches:
>2948G (1) - distribution switch
>2900xl (8) - access switches
>various numbers of 1900/2800 to be phased out
>
>Cisco Aironet Wireless:
>2 parabolic, various yaggi and omni antennae
>a number of workgroup and access bridges, various sizes.

>The new environment will consist entirely of new servers, no upgrades

>Currently our network is on one segment and I am creating vlan's. This

>Physical Sites consist of:
>
>Main site; includes main administrative building and 6 outlying
>quonset (huts). Fiber from main building to one hut, fiber between
>huts. Currently in place and operable. Main server room; distribution
>switch, access switches in main building and physical locations.
>
>Heritage site: approx. 4 miles from main. Will connect to Main Site
>via Aironet, parabolic at Heritage and at Main.
>
>Northstar site: approx. 400 yds. from Heritage, connected via fibre,
>currently in place and operable.
>
>Daycare site: approx. 800 yds. from Heritage, will connect via
>Aironet.
>
>Home: approx. 1 mi. from Heritage, will connect via Aironet.
>
>All operations must take place within 10.200.x.x range. Our
>organization is one of three trees within the 2000 forest. Each tree
>is an independent organization with close ties. One domain per tree.
>
>My plans:
>
>All servers are Windows 2000, all desktops 2000 Professional.
>Each VLAN consists of 6 ports on the 2948 switch, each port (as
>needed) will go to a 2900xl switch for eventual end user access,
>possible direct 2948 to desktop in some cases.
>
>VLAN 1
>10.200.1.x / 24
>Serving enterprise;
>Exchange 2000 / Universal file server box
>ISA (firewall) box
>Primary DNS, DC, DHCP, Global Catalog
>
>VLAN 2
>10.200.2.x / 24
>File server for info systems, main building.
>Secondary DNS, DC
>DHCP?
>3 users
>
>VLAN 3
>10.200.3.x / 24
>File server for huts.
>SQL backend server for online application, access from huts.
>DHCP?
>50 users, web server.
>
>VLAN 4
>10.200.4.x / 24
>One box, 6450, SQL server and file server for finance and services,
>main building.
>DHCP?
>6 - 12 users, critical data, high resource demand
>
>VLAN 5
>10.200.5.x / 24
>File server for administrative staff, main building.
>DHCP?
>75 users
>
>VLAN 6
>10.200.6.0 / 24
>Spans from main building to heritage center, approx. 4 miles distant.
>Parabolic and bridge, Aironet, at main building and Heritage center.
>Bridge on each end connected to a 2900xl switch.
>File server for Heritage center, possibly daycare.
>Daycare connected via workstations -> 2900xl -> aironet -> heritage
>Northstar has own servers, connected to Heritage via fiber.
>Home will connect to Heritage via wireless (low priority).
>Possible (probable) second server at Heritage, possible server at
>Daycare.
>DNS (cache only), DC, Global Catalog
>DHCP?
>50 users
>
>VLAN 7
>Not utilized.
>
>VLAN 8
>Gateway to existing Banyan network.
>
>
>So there we have it.

>This is actually my first time writing it out in detail and that in
>itself has been beneficial.
>If anyone is feeling ambitious and generous I would more than welcome
>a picking apart of my logic, diagramming, any input at all welcome.
>I'm sure I have some gaping omissions, leaps of logic or
>considerations not yet considered. Chances are I'm going overboard
>with the segmenting? I realize the extra admin chores but think the
>trade off is tolerable.
