Usage Guidelines

The device starts the tx-period timer in either of the following situations:

When the client initiates authentication and MAC address bypass authentication is not configured, the device sends a unicast Request/Identity packet to the client and starts the tx-period timer. If the client does not respond within the period set by the timer, the device retransmits the authentication request.
To authenticate the 802.1X clients that cannot initiate authentication, the device periodically sends multicast Request/Identity packets through the 802.1X-enabled interface to the clients at the interval set by the tx-period timer.

After MAC address bypass authentication is enabled on a device, the interval at which the device sends unicast Request/Identity packets to clients is determined by delay-time-value configured in the dot1x timer mac-bypass-delay command and max-retry-value configured in the dot1x retry command. The retransmission interval is the integer part of the value calculated using the following formula: delay-time-value/(max-retry-value + 1)

Normally, it is recommended that you retain the default setting of the timer.

Example

# Set the interval at which the device sends authentication requests to 90 seconds.
