Port-Based Authentication Methods
Table 29 on page 194 lists the authentication methods supported in these host modes:
Single host—Only one data or voice host (client) can be authenticated on a port.
Multiple host—Multiple data hosts can be authenticated on the same port. (If a port becomes unauthorized in
multiple-host mode, the switch denies network access to all of the attached clients.)
Multidomain authentication (MDA)—Both a data device and voice device can be authenticated on the same switch
port. The port is divided into a data domain and a voice domain.
Multiple authentication—Multiple hosts can authenticate on the data VLAN. This mode also allows one client on the
VLAN if a voice VLAN is configured.
