Enable automatic interface activation after its disconnection in the 
following circumstances:  
- loopback-detection—loopback-detection 
- port-security—security breach for port security 
- dot1x-src-address—user MAC authentication failed 
- acl-deny—non-compliance with access lists (ACL) 
-  stp-bpdu-guard—BPDU  Guard  activation  (unauthorized  BPDU 
packet reception via the interface) 
- stp-loopback-guard—loopback detection using the STP protocol.
