Is there a way to speed up the NAC portal authentication.
So the guest get the portal page and select to accept the use policy but then it took a while to get the success - there is this loading animation.

Anyone know a trick to make it faster ?

Thx,
Ron

I get the "registration in progress" animation for about 10-20 seconds.

I use a bridge@EWC topology and the roles are contain to VLAN - they client doesn't change the VLAN only different roles/ACLs for unregistered/guest access.

That is actually a very good speed.  During the transition to the policy or vlan that is assigned after the registration occurs, you must remember that there is a re-auth that takes place, and hence another IP Resolution process that also occurs, prior to NAC redirecting the page to whatever URL.  That is a good time;  some take upwards of 30 seconds.  Everyone’s networks is different and if they are changing vlans that can exacerbate the delay.

We had a discussion with an extreme engineer last week about  some changes made in the latest NAC release  that can at least speed up the appearance of connecting.   If I remember correctly it involved skipping the accessing /registration redirect  page and instead having the  NAC agent throwing up a dialog box if the process failed.    As always there are trade offs and network designs vary greatly.  It  may be worth a look.
