What else should you make sure to do?

Refer to the scenario.

A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).

Switches are using local port-access policies.

The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the “eth-internet" role. The gateway should also handle assigning clients to their VLAN, which is VLAN 20.

The plan for the enforcement policy and profiles is shown below:

The gateway cluster has two gateways with these IP addresses:

• Gateway 1

o VLAN 4085 (system IP) = 10.20.4.21

o VLAN 20 (users) = 10.20.20.1

o VLAN 4094 (WAN) = 198.51.100.14

• Gateway 2

o VLAN 4085 (system IP) = 10.20.4.22

o VLAN 20 (users) = 10.20.20.2

o VLAN 4094 (WAN) = 198.51.100.12

• VRRP on VLAN 20 = 10.20.20.254

The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.

Assume that you have configured the correct UBT zone and port-access role settings. However, the solution is not working.

What else should you make sure to do?
A .  Assign VLAN 20 as the access VLAN on any edge ports to which tunneled clients might connect.
B. Create a new VLAN on the AOS-CX switch and configure that VLAN as the UBT client VLAN.
C. Assign sufficient VIA licenses to the gateways based on the number of wired clients that will connect.
D. Change the port-access auth-mode mode to client-mode on any edge ports to which tunneled clients might connect.
