Allied Telesis UniDirectional Link Detection - License - 1 License - AT-FL-GS97-UDLD
The Allied Telesis UniDirectional Link Detection (UDLD) feature is a Layer 2 protocol that detects and mitigates unidirectional links between devices on a network. Unidirectional links occur when a link is configured between two devices but only one of the devices receives traffic. This can result in a number of problems, including performance degradation, packet loss, and device instability.
The UDLD feature uses a combination of active and passive mechanisms to detect unidirectional links. Active mechanisms involve sending and receiving probe packets between devices. Passive mechanisms involve monitoring the traffic patterns between devices. When a unidirectional link is detected, the UDLD feature will take steps to mitigate the problem, such as disabling the link or sending a notification to the administrator.
The UDLD feature is available on a variety of Allied Telesis products, including switches, routers, and firewalls. It is a valuable tool for ensuring the reliability and performance of your network.
