Restrictions for Configuring UniDirectional Link Detection
The following are restrictions for configuring UniDirectional Link Detection (UDLD):
-
A UDLD-capable port can’t detect a unidirectional link if it’s connected to a UDLD-incapable port of another device.
-
When configuring the mode (normal or aggressive), make sure that the same mode is configured on both sides of the link.
Caution |
Loop guard works only on point-to-point links. We recommend that each end of the link has a directly connected device that is running STP. |
