Hello everyone, this is my first post here and I just found this site yesterday..I have to say I'm LOVING this site and all the knowledge here. Looking forward to learning much more as time goes by.
So, my situation is as follows:
Network with 5 locations, using 3640 routers between them and before I inherited the network, the IT director decided that VLANS weren't needed. Here's what I'm re-designing to include VLANS.
4 3640 routers at remote sites
1 3745 router at main location
30+ catalyst switches (mostly catalyst 2950, 3524 & 3550 series my core switch is a 3750 layer 3 switch that will be the VTP server)
200+ Cisco IP phones (mostly 7940-7960s but a few 7910s and 12s running around and quite a few ATAs).
pix 515 firewall with memory max'd out for internet access.
lots more junk that I can't think of off the top of my head, but stuff like netgear switches for smaller stuff
[/ul]
So, with all that being said...I'm just looking for some more solid confirmation about my plan with the config of the network.
At the headquarters location, we have LOTS of computers and a bunch of switches so my plan was to use 12 vlans to segment organizational groups and equipment as follows:
VLAN1 = management vlan
VLAN10 = data vlan (servers in NOC)
VLAN11 = data vlan (admin/director building)
VLAN12 = data vlan (seasonal groups)
VLAN13 = data vlan (sub organization)
VLAN14 = data vlan (sub organization)
VLAN20 = voice vlan (admin/director building)
VLAN21 = voice vlan (seasonal groups)
VLAN22 = voice vlan (sub organization)
VLAN23 = voice vlan (sub organization)
VLAN30 = restricted vlan (for inet access in the coffee shops, etc.)
VLAN40 = printers vlan
I have so far decided that at each of the remote sites, I want to setup 5 VLANs. Being:
VLAN1 = management vlan
VLAN10 = data vlan
VLAN20 = voice vlan
VLAN30 = restricted vlan
VLAN40 = printers vlan
Hopefully it makes sense what I'm trying to do here. I'm trying to make network segments match vlan ID's and making all this as standardized as possible. I think I have a pretty large network for being ONE guy to deal with all of it. I think we have around 30 servers at the moment and close to 250-260 workstations and at LEAST that many ip phones on the network, hence the redesign.
We're getting broadcast storms and all, it's not really effecting application performance on a large scale but I can personally tell that it's starting to and we're about to add another 8 switches on the main LAN because of another office building coming online in the June. That's not to mention the new warehouse building that's being built that will house at least 1 more switch.
So, any other words of wisdom in planning all of this? I'm a total newb to vlans and this will be my first real go at it. Look forward to hearing back from you all!
