FAQ-Which VLAN Do DHCP Users Connected to a Switch Interface Obtain IP Addresses From If MAC Address Authentication Is Enabled and a Guest VLAN Is Configured on the Interface

Publication Date:  2015-03-25 Views:  693 Downloads:  0

Issue Description

Which VLAN Do DHCP Users Connected to a Switch Interface Obtain IP Addresses From If MAC Address Authentication Is Enabled and a Guest VLAN Is Configured on the Interface?

Solution

When a user without VLAN tag passes MAC address authentication, the user obtains an IP address from the VLAN matching the interface PVID. When a user with a VLAN tag passes MAC address authentication, the user obtains an IP address from the VLAN matching the VLAN tag.

If a user fails MAC address authentication, the user obtains an IP address from the guest VLAN on the interface where the user accesses.
