How to set up MAC authentication on the Captive Portal(XIQ-C)

ufaf0052 — Fri, 14 Mar 2025 15:07:10 GMT

XIQ-C fails to obtain an IP address from the DHCP server after the MAC authenticator fails.
As a result, the next step, redirecting to an external captive portal, also cannot proceed.

1. stationEvents.log Output:

12/03/25 12:50:03.816 MBA Rejected 80:07:94:DE:21:47 VGHTCAP Network[VGHTCAP]
12/03/25 12:50:03.816 De-registration 80:07:94:DE:21:47 VGHTCAP Network[VGHTCAP] Cause[Client authentication failed]

Unable to Obtain DHCP IP After Upgrading to XIQ-C 10.x
In XIQ-C 8.x, the following CLI commands were available:

# unauth-behaviour nonauth-policy
# apply
# show unauth-behaviour

What is the problem when the client cannot get an IP?

There are a lot of steps to double check.

Go here : https://supportdocs.extremenetworks.com/support/documentation/extremecloud-iq-controller-latest-documentation/ and follow the steps in the ExtremeCloud IQ Controller version 10.10.01 Deployment Guide

After the upgrade to XIQ-C 10.x, the old “nonauth-behaviour” CLI flow is no longer handled the same way, which can break unauth forwarding. Because of that, the device isn’t getting placed into the correct unauth VLAN or policy for DHCP. You may need to re-check the guest/unauth policy mapping and captive portal redirect settings in the new version.
