Parameters
text: Interface description, a case-sensitive character string of 1 to 240 characters. The string can include
case-sensitive letters, digits, special characters, and other Unicode characters and symbols. Special
characters include tilde (~), exclamation point (!), at sign (@), pound sign (#), dollar sign ($), percent
sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right brace (}), left parenthesis ((), right
parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<), right angle bracket (>), hyphen (-),
underscore(_), plus sign (+), equal sign (=), vertical bar (|), back slash (\), colon (:), semi-colon (;)

link-delay
Use link-delay to set the physical state change suppression interval on a WAN interface.
Use undo link-delay to restore the default.
Syntax
link-delay delay-time
undo link-delay
Default
Physical state change suppression is disabled on a WAN interface. The system detects the physical state
changes of interfaces every 5 seconds. When a physical state change occurs, the system detects the
change within 5 seconds and immediately reports the detected change.

Default command level
2: System level
Parameters
delay-time: Sets the physical state change suppression interval in seconds, in the range of 0 to 10. A
value of 0 disables physical state change suppression.
Usage guidelines
Suppose you set the delay-time argument to a value in the range of 1 to 10, for example, 2, for an
interface. When a physical state change occurs to the interface, the system detects the change within 5
