WLAN Profile and roaming

nsafo — Mon, 05 Jul 2021 15:31:44 GMT

Q1. is wlan profile locally significant to the wlc it is in?

Q2. if the wlan profile doesn't much b/n controllers in the same mobility group, does it affect roaming and how? (assume the SSID is the same on both controllers)

Example:

wlc1

ssid profile:test01

ssid:test

wlc2

ssid profile:test02

ssid:test

I do not think that matters.

Each AP is having unique BSSID in each band (ie MAC address associate with given SSID , derived from base radio mac address in 2.4GHz & 5GHz radio). That is how you differential two cells that advertise same SSID when it comes to roaming.

Thanks Rasika

What i am trying to do is, break roaming where ever it is not required.

scenario 1

I have used WLAN profiles with the same SSID to break the l3 intra-controller roaming.

example:

with intra-controller roaming in effect:

wlc-1:

wlan profile name:test1

ssid: test

wlan id: 50

AP-Group-1

Wlan id: 50

Vlan 10

AP-Group-2

Wlan id: 50

Vlan 20

assume the client is connected first on an AP in AP-GROUP1, When the client roams to an AP in AP-GROUP2, the IP of the client will be maintained.

breaking the intra-controller roaming:

wlc-1:

wlan profile name:test1

ssid: test

wlan id: 50

wlan profile name: test2

ssid: test

wlan id: 51

AP-Group-1

Wlan id: 50

Vlan 10

AP-Group-2

Wlan id: 51

Vlan 20

assume the client is connected first on an AP in AP-GROUP1, When the client moves to an AP in AP-GROUP2, the IP of the client will change and it will be a new association to WLAN ID:51.

Scenario 2

if i want to break the inter-controller l2/l3 roaming, can i use the same solution as scenario 1? in my test, i learned it doesn't matter, i saw a normal L3 inter-controller roaming.

i know changing the mobility domain name can break l2/l3 roaming but i am checking if wlan profile has any use in breaking inter-controller roaming.

Thanks for the detail explanation.

If you do not want to have client roam, I will design RF in a way, there is no overlapping coverage. This will result client to drop connection when they go from one cell to another (that you do not require client to roam)

Why you wan to break these normal roaming behavior in a overlapping cells ? what you trying to achieve by doing such thing.
