Dynamic VLAN for wireless

[chennai.itsupport]

Hi Team,

I have a doubt .....

In our office we have 4 access point .... and as wifi users increases we are planning to create 4 VLAN and each VLAN

have one AP .. but the problem is When wifi users roam from one AP to another AP i,e from one vlan to another vlan they get disconnected.

My question is .... if i deploy dynamic VLAN, will the client be able to get connected to the internet when roaming from one VLAN to another VLAN

without any hiccups .... as this can be real issue when they are on call or transferring files

Below is our current network topology:

Router: LAN: 192.168.1.1 255.255.255.0

DHCP Scope on Router:

VLAN1 - 192.168.1.3 - 250 

VLAN10 - 192.168.10.3 - 250

VLAN20 -  192.168.20.3 - 250

VLAN30 - 192.168.30.3 - 250

VLAN40 - 192.168.40.3 - 250

Switch SG300: L3 Mode

VLAN1 - ip 192.168.1.254 (Default VLAN)

VLAN10 - ip 192.168.10.254

VLAN20 - 192.168.20.254

VLAN30 - 192.168.30.254

VLAN40 - 192.168.40.254

AP1 = VLAN10, AP2 = VLAN20, AP3 = VLAN30, AP4 = VLAN40

All local routing between the VLANs are taken care by the Switch

and the router is routing the traffic for all VLANs when client wants to go to internet...

Pliz help......

Hi,

can you please mention are using any controller for these ap's.

If so they should not disconnect because all the traffic is handled by controller.

let say you have client 1 on AP1 as below,

client1- AP1---- AP2

when it roam from AP1 to AP2 it should not disconnect. Due to mobility functionality client should not disconnect nor loss the traffic. Only controller get updated with AP binding table
