Hi all,
I try to set up multiple Vlan but my issue is to associate them ip subneting.
This is the example:
I want to make some Vlans:
- 1 for Data
- 1 for Voice
so I make the ssid
dot11 ssid data
vlan 100
authentication ...
!
dot11 ssid voice
vlan 200
authentication open
authentication key-management wpa
wpa-psk ascii ...
!
interface Dot11Radio0.100
encapsulation dot1Q 100 native
no ip route-cache
bridge-group 1
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
interface Dot11Radio0.200
encapsulation dot1Q 200
no ip route-cache
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
interface FastEthernet0.100
encapsulation dot1Q 100 native
no ip route-cache
bridge-group 1
no bridge-group 1 source-learning
bridge-group 1 spanning-disabled
!
interface FastEthernet0.200
encapsulation dot1Q 200
no ip route-cache
bridge-group 1
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
and the BVI
interface BVI1
description Basic Virtual Interface
ip address A.B.C.D /24
no ip route-cache
the BVI interface is in the native Vlan of Data. My issue is that I want to have on subnet 192.168.1.0/24 for Data and another 192.168.2.0/24 for the voice
but the problem is that I always get dhcp info from the subnet where the BVI is.
Can anybody help me on that ?
I assume that the DHCP request is ?ade by the IP of the BVI (when helper activated) so this is why I always get an IP from the data pool where the BIV is into.
I started to think to some solution like create a BVI2 but this is a lost of IP
or directly assign ip from sub ethernet int and activate the helper.
What is the best and what do you think of that ?
Thanks in advance
Matt

Define a third "native" vlan for the BVI. Don't map it to a radio interface or SSID.
Do follow Bill's suggestion to use the web interface. You'll see the correct bridge groups built for you.

Assign a interface name BVI100 and assign an ip address in the range of 192.168.1.0 and assign a ip helper-address

Your problem is all your interfaces are using bridge group 1. change the bridge group number to match the corresponding VLAN and things should improve as long as the switch port is configured for trunking/.1Q support.
Suggestion initially configure the VLAN's using the WEB interface and then check the config and see the result.

Hi all,
first thanks very much for all your answer, I'm pretty busy and I keep that for some of my dead time.
I will test all of that and let you know the result
thanks again

So I worked to find what was going wrong with Bridge an routing. And I find the issue, now all work fine I can have a subnet over each ssid
Thanks again
