After port security is deployed throughout an enterprise campus, the network team has been overwhelmed with port reset requests. They decide to configure the network to automate the process of re-enabling user ports. Which command accomplishes this task?

  • A. switch(config)# errdisable recovery interval 180
  • B. switch(config)# errdisable recovery cause psecure-violation

  • D. switch(config)# switchport port-security aging type inactivity
  • E. switch(config)# errdisable recovery cause security-violation

Suggested Answer: B 🗳️
When a secure port is in the error-disabled state, you can bring it out of this state automatically by configuring the errdisable recovery cause psecure-violation global configuration command or you can manually reenable it by entering the shutdown and no shut down interface configuration commands. This is the default mode. If a port is in per-VLAN errdisable mode, you can also use clear errdisable interface name vlan range command to re-enable the VLAN on the port.
You can also customize the time to recover from the specified error disable cause (default is 300 seconds) by entering the errdisable recovery interval interval command.

Sure, you are wrong. B is correct answer. Changing interval you are not enable errdisable recovery, you must configure cause of errdisable for recovery. And question not about udld, bpduguard etc., it is all about port-security.

psecure-violation is one of the many possible causes for errdisable state. errdisable recovery interval makes the switch to automatically recover from all the possibles causes: udld, bpduguard, etc
