Configuring IEEE 802.1x Authentication Chapter 7 Configuring IEEE 802.1x Port-Based Authentication Table 7-2 Default IEEE 802.1x Authentication Configuration (continued) Feature Authenticator (switch) mode MAC authentication bypass Default Setting None specified. Disabled. IEEE 802.1x Authentication Configuration Guidelines These section has configuration guidelines for these features: • IEEE 802.1x Authentication, page 7-20 • VLAN Assignment, Guest VLAN, Restricted VLAN, and Inaccessible Authentication Bypass, page 7-21 • MAC Authentication Bypass, page 7-22 IEEE 802.1x Authentication These are the IEEE 802.1x authentication configuration guidelines: • When IEEE 802.1x authentication is enabled, ports are authenticated before any other Layer 2 feature is enabled. • If you try to change the mode of an IEEE 802.1x-enabled port (for example, from access to trunk), an error message appears, and the port mode is not changed. • If the VLAN to which an IEEE 802.1x-enabled port is assigned changes, this change is transparent and does not affect the switch. For example, this change occurs if a port is assigned to a RADIUS server-assigned VLAN and is then assigned to a different VLAN after re-authentication. If the VLAN to which an IEEE 802.1x port is assigned to shut down, disabled, or removed, the port becomes unauthorized. For example, the port is unauthorized after the access VLAN to which a port is assigned shuts down or is removed. - Trunk port-If you try to enable IEEE 802.1x authentication on a trunk port, an error message appears, and IEEE 802.1x authentication is not enabled. If you try to change the mode of an IEEE 802.1x-enabled port to trunk, an error message appears, and the port mode is not changed. - Dynamic ports-A port in dynamic mode can negotiate with its neighbor to become a trunk port. If you try to enable IEEE 802.1x authentication on a dynamic port, an error message appears, and IEEE 802.1x authentication is not enabled. If you try to change the mode of an IEEE 802.1x-enabled port to dynamic, an error message appears, and the port mode is not changed. - Dynamic-access ports-If you try to enable IEEE 802.1x authentication on a dynamic-access (VLAN Query Protocol [VQP]) port, an error message appears, and IEEE 802.1x authentication is not enabled. If you try to change an IEEE 802.1x-enabled port to dynamic VLAN assignment, an error message appears, and the VLAN configuration is not changed. - EtherChannel port-Do not configure a port that is an active or a not-yet-active member of an EtherChannel as an IEEE 802.1x port. If you try to enable IEEE 802.1x authentication on an EtherChannel port, an error message appears, and IEEE 802.1x authentication is not enabled. 7-20 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide OL-8915-01
