When Extreme Wireless V2110 Down in Bridge mode

[Shooter_Chiang]

Hi Everyone,

V2110 : V9.15
AP : AP3825i

VNS Setting : Bridge Mode

1. SSID1: PSK + WPA2
2. SSID2 : MAC Auth with NAC
3. SSID3 : External Portal with NAC

When AP setting : Restart service in the absence of controller -> enable
===================================================
Click to Enable or Disable (if using a bridged at AP VNS) to ensure
the AP continues providing service if the AP’s connection to the
controller is lost. If this option is enabled, it allows the AP to start a
bridged at AP VNS even in the absence of a controller.
===================================================

When V2110(only one) Down,there is no Controller,but NAC is UP

SSID1 -> old session work fine
new session work fine

SSID2 -> old session work fine
new seesion can work ?

SSID3 -> old session not work
new seesion not work

How can I make SSID2 and SSID3 work fine with new session when V2110 down ?

Thanks

Regards,
Shooter

Thanks for your help.

Yes, that would be your best option as Ron described below. Both controllers should have the identical configurations for fast fail-over in the event an appliance goes offline...
