Range: 1 to 4094 Not configured CONFIGURATION (conf-if-interface-slot/port) Version 8.3.19.0 Version 8.3.7.0 Version 7.6.1.0 Introduced on S4820T Introduced on S4810 Introduced on C-Series, E-Series, and S-Series 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, will occur 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: Layer 3 portion of guest VLAN and authentication fail VLANs can be created regardless if the VLAN is assigned to an interface or not. Once an interface is assigned a guest VLAN (which has an IP address), then routing through the guest VLAN is the same as any other traffic. However, interface may join/leave a VLAN dynamically.
