dot1x unicast-trigger

Function

The dot1x unicast-trigger command enables 802.1X authentication triggered by unicast packets.

The undo dot1x unicast-trigger command disables 802.1X authentication triggered by unicast packets.

By default, 802.1X authentication triggered by unicast packets is disabled.

Format

In the system view:

dot1x unicast-trigger interface { interface-type interface-number1 [ to interface-number2 ] } &<1-10>

undo dot1x unicast-trigger interface { interface-type interface-number1 [ to interface-number2 ] } &<1-10>

In the interface view:

dot1x unicast-trigger

undo dot1x unicast-trigger

Parameters

Usage Guidelines

After the dot1x unicast-trigger command is used on the device, the device sends a unicast packet to respond to the received ARP or DHCP Request packet from a client. If the client does not respond within the timeout interval (set by the dot1x timer command), the device retransmits the unicast packet (the maximum of retransmission count is set by the dot1x retry command). During 802.1X-based network deployment, 802.1X users can start 802.1X authentication without installing specified client dial-in software, which facilitates network deployment.

The dot1x unicast-trigger command has the same function as the dot1x dhcp-trigger command.
