Troubleshooting Portal; Inconsistent Keys On The Access Device And The Portal Server - HP 5120 SI Series Security Configuration Manual

# Correlate DHCP server group 1 with VLAN-interface 3.
[Switch-Vlan-interface3] dhcp relay server-select 1
[Switch-Vlan-interface3] quit
Verifying the configuration
Before user userpt accesses a web page, the user is in VLAN 8 (the initial VLAN), and is assigned with
an IP address on subnet 192.168.1.0/24. When the user accesses a web page on the external network,
the web request will be redirected to authentication page https://4.4.4.4/portal/logon.htm. After
entering the correct username and password, the user can pass the authentication. Then, the device will
move the user from VLAN 8 to VLAN 3, the authorized VLAN. You can use the display connection
ucibindex command to view the online user information

Use the display mac-vlan all command to view the generated MAC-VLAN entries, which record the MAC
addresses passing authentication and the corresponding VLANs.

If a client fails authentication, it will be added to VLAN 2. Use the previously mentioned commands to
view the assigned IP address and the generated MAC-VLAN entry for the client.
