Dynamic ARP inspection. If dynamic ARP inspection (DAI) is enabled and the threshold 
value is reached, the interface is placed in the D-Disable state. If autorecovery is enabled, 
the interface comes back up after the time-out interval expires.
DHCP rate limiting. If DHCP snooping is enabled and the incoming DHCP packet rate 
exceeds the threshold, the interface is placed in the D-Disable state. If autorecovery is 
enabled, the interface comes back up after the time-out interval expires.
UDLD. If Unidirectional Link Detection (UDLD) is enabled and the unidirectional 
connection is detected, the interface is placed in the D-Disable state. If autorecovery is 
enabled, the interface comes back up after the time-out interval expires.
The following example shows how you can configure autorecovery for UDLD, change the 
time-out interval for autorecovery, and show the status of autorecovery for all features:
1.
