DIFFRENT SUBNET IS POSSIBLE OR NOT FOR ONE VLAN

Hi ,

i have a client they have main office and some 10 branches connected via 1 mbps link .

We put new WLC 5508 in main office (software version 6.0.199.4) and i connected braches 1142 ap's and they registerd with WLC .

Now client have 3 ssid 1> scanners  2>network  3> guest

They want to show same ssid in all branches no single change requried  on ssid .

suppose the scanners connecte in main offcie via mac filtering and they will get ip range 192.168.1.0

and when from branch a there they have different range they should get 172.16816.0 range .

the ssid network will be acs authentication and  ssid guest will be preshared key . All the ssid ip range will be differnt in branches but they want same ssid . Is it possible.( Can any body give me the steps )

Also one more issue am facing is . in MAIN OFFICE switch vlan 600 for ssid scanners range 192.168.1.0  

and in branch same vlan 600 for ssid scanners ip range is 172.168.16.0     . so am getting some error when i save in WLAN SSID enable and save .

Re: DIFFRENT SUBNET IS POSSIBLE OR NOT FOR ONE VLAN

Hi,

If you have all your WLANs centrally switched then you can use AP groups:

If you have local switching enabled for the SSID then you may need to use HREAP groups. You can override the VLAN in each branch office to use a local significant VLAN. You  need DHCP server in each bran office for this.

Here are some useful links:
