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

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.

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.

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.
