2.2.10 UDLD configuration

UDLD （UniDirectional Link Detection）：Is a two-layer protocol that monitors the physical

configuration of an Ethernet link using fiber or twisted pair connections. When a unidirectional

link (only one direction is transmitted, for example, I can send you data, Receive, but you send me

the data I can not receive), UDLD can detect this situation, close the corresponding interface and

send a warning message。Unidirectional links can cause a lot of problems, especially spanning

trees, which may cause loops。Note: UDLD requires both ends of the link to be supported for

normal operation。

UDLD supports two modes of work: common (normal) mode (default) and radical

(aggressive) mode

UDLD supports two modes of work: common (normal) mode (default) and

radical (aggressive) mode

UDLD supports two modes of work: common (normal) mode (default)

and radical (aggressive) mode

UDLD supports two modes of work: common (normal) mode

(default) and radical (aggressive) mode。

General (normal) mode: in this mode, UDLD can detect unidirectional links and label ports

as undetermined states to generate system logs，In other words, normal mode will shut down a port
