Dell Force10 Z9000 - Dot1 X Mac-Auth-Bypass; Dot1 X Max-Eap-Req

Usage
Information
802.1X authentication is enabled when an interface is connected to the switch. If the host fails
to respond within a designated amount of time, the authenticator places the port in the guest
VLAN.
If a device does not respond within 30 seconds, it is assumed that the device is not 802.1X
capable. Therefore, a guest VLAN is allocated to the interface and authentication for the
device occurs at the next re-authentication interval (dot1x reauthentication).
If the host fails authentication for the designated amount of times, the authenticator places the
port in authentication failed VLAN (dot1x auth-fail-vlan).
NOTE: The layer 3 portion of guest VLAN and authentication fail VLANs can be created
regardless if the VLAN is assigned to an interface or not. After an interface is assigned a
guest VLAN (which has an IP address), routing through the guest VLAN is the same as any
other traffic. However, the interface may join/leave a VLAN dynamically.
