Wireless L3 Roaming

lenkasurat · ‎08-17-2015

Hello Experts,

Hope you are doing well!

I am using 5508 controller and couple of sites are used on Flexconnect mode, I want to know if I can configure L3 roaming on the SSID? if, yes how?

Thanks in advance!

Hi lenkasurat,

For the sites running Flexconnect mode is the SSID set to Local or Central Switching? You will be unable to perform L3 Roaming on the APs in local switching mode. This table below is sort of helpful but see the full feature matrix here:

Mobility / Roaming Scenarios

WLAN Configuration	Local Switching			Central Switching
WLAN Configuration	CCKM	PMK (OKC)	Others	CCKM	PMK (OKC)	Others
Mobility Between Same Flex Group	Fast Roam⁽¹⁾	Fast Roam⁽¹⁾	Full Auth⁽¹⁾	Fast Roam	Fast Roam	Full Auth
Mobility Between Different Flex Group	Full Auth⁽¹⁾	Fast Roam⁽¹⁾	Full Auth⁽¹⁾	Full Auth	Fast Roam	Full Auth
Inter Controller Mobility	N/A	N/A	N/A	Full Auth	Fast Roam	Full Auth
⁽¹⁾ Provided WLAN is mapped to the same VLAN (same subnet).

No L3 roaming support in FlexConnect design (except central switching which is similar to local mode AP deployment).
