Hi everyone!
I'm a self taught cisco type person who really specialises in ASA rather than routers, but have fumbled my way through many a task with the help of this site and google... However! I am currently tasked with setting up a network, pretty much from scratch, that requires some fairly hefty VLAN deployment.
My hardware on hand (already existed so can't can't change anything easily) 5x ESW-540-48 Switches, 1x3750g switch, 1x2811 router.
I don't believe the router should be required as the 3750 is capable of intervlan routing. So what i'm trying to achieve is as follows:
VLAN 1 - 172.16.8.0/22 (A)
VLAN 2 - 10.0.2.0/24 (B)
VLAN 3 - 10.0.3.0/24 (C)
VLAN 4 - 10.0.4.0/24 (D)
VLAN 5 - 10.0.5.0/24 (E)
VLAN 6 - 10.0.6.0/24 (F)
VLAN 7 - 10.0.7.0/24 (G)
VLAN 8 - 10.0.8.0/24 (H)
VLAN 9 - 10.0.9.0/24 (I)
Server Room - Servers connected to the 3750G
3750G connected to 5 ESW switches distributed around the building.
ESW-1 Will have VLAN(A) and VLAN(B) devices connected, specified at port level.
ESW-2 Will have VLAN(A) and (C) devices connected, specified at port level.
ESW-3 Will have VLAN(A), (D), (E) and (F) devices connected, specified at port level.
ESW-4 Will have VLAN(A), (G) devices connected specified at port level.
ESW-5 Will have VLAN(A), (H) and (I) devices connected, specified at port level.
Now at one point I actually had the VLAN's *working* in that I could specify an IP address and could ping to and from it! However DHCP wasn't passing despite numerous attempts with DHCP relay and IP-Helper configurations.
Also I was having issues with VLAN 1 as the native VLAN, the ESW switches don't allow you to do much with them, as they 'weren't created by the user'. So tried switching that out to VLAN11 also but with very little success there (I had to change the native vlan on all trunks to VLAN 11)
All the 10.x.x.x addresses need to be able to communicate with each other
All the ESW switches need to be able to handle their respective VLAN's as well as VLAN 1 (for Printers and wireless access points distributed around the building).
Partly i'm doing this in the hope that maybe some helpful soul can make some sense of it, but also just the fact of writing it down MAY firm it up in my head somewhat
Thanks in advance!
Simon
