The authentication parameters are described for all ports. All fields except the following are

single-host mode, from a host whose MAC address is not the supplicant MAC address.
STEP 2 Select a port, and click Edit.
STEP 3 Enter the parameters.
• Interface—Enter a port number for which host authentication is enabled. The OOB port
is not included.
