xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide
Conditions and Limitations
1. If the client is utilizing DHCP to attain an IP address, the authentication VLAN must provide a DHCP server
or a DHCP relay function so that client may obtain an IP address.
2. Certain functions exist on the Switch that will filter HTTP packets, such as the Access Profile function. The
user needs to be very careful when setting filter functions for the target VLAN, so that these HTTP packets
are not denied by the Switch.
3. If a RADIUS server is to be used for authentication, the user must first establish a RADIUS Server with the
appropriate parameters, including the target VLAN, before enabling Web Authentication on the Switch.
