To decrease Virtual controller failover sysc time

Hi,

I have IAP 205 VC with 20 IAP with latest AOS.

While Master IAP goes down and new IAP become master, i observed that wireless user connection drop and 5-6 ping drop. Once master elected wireless client asking for credential (Guest self registration)

 

How can we decrease master failover sync time/ping drop or how to avoid existing wirless user connection drop?

 

Thanks..

The connection for ALL users, or only the users that are connected to the VC drops?

Is your WLAN using a  VC-Assigned VLAN?  In that case, all of the guest traffic is tunneled to the VC, so there has to be a VC election to decide who will handle and nat that traffic.  The minimum failover time should be 10 seconds, really.  If you are achieving 5 seconds, that is good.

 

If you were using 802.1x and you had a network-assigned VLAN, the AP a user is assigned to would just keep passing traffic, even during the VC election, because the data traffic would be truly distributed.

Re: To decrease Virtual controller failover sysc time

Hi,

 

I am not using VC assigned vlan for WLAN.

I hv 2 SSID Employee(vlan 10) and Guest(vlan 20). My network L3 switch leasing IP address for WLAN.

IAP is getting IP address from vlan 10.

 

Do i need to configure saperate management vlan for IAP?

 

Thanks...

A best practice is to have a separate management VLAN for your IAP, yes.
