Configuring IEEE 802.1x Authentication Chapter 9 Configuring IEEE 802.1x Port-Based Authentication Table 9-2 Default IEEE 802.1x Authentication Configuration (continued) Feature Retransmission time Maximum retransmission number Client timeout period Authentication server timeout period Guest VLAN Inaccessible authentication bypass Restricted VLAN Authenticator (switch) mode MAC authentication bypass Default Setting 30 seconds (number of seconds that the switch should wait for a response to an EAP request/identity frame from the client before resending the request). 2 times (number of times that the switch will send an EAP-request/identity frame before restarting the authentication process). 30 seconds (when relaying a request from the authentication server to the client, the amount of time the switch waits for a response before resending the request to the client.) 30 seconds (when relaying a response from the client to the authentication server, the amount of time the switch waits for a reply before resending the response to the server. This setting is not configurable.) None specified. Disabled. None specified. None specified. Disabled. IEEE 802.1x Authentication Configuration Guidelines These section has configuration guidelines for these features: • IEEE 802.1x Authentication, page 9-20 • VLAN Assignment, Guest VLAN, Restricted VLAN, and Inaccessible Authentication Bypass, page 9-21 • MAC Authentication Bypass, page 9-22 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. 9-20 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
