Auto-Recovery of a Disabled Port


Physical ports are automatically disabled by Netvisor One due to certain violations. For example, if a port receives BPDU messages from an edge port, Netvisor One disables the port because receiving BPDUs on a edge port is a security violation. However, there is no way to indicate that the port is shut down because of a violation and not because of physical link issues.


The port may be disabled due to the following errors:


  • BPDU Guard Messages
  • The port is set to Err disabled when a BPDU Guard message is received on an Edge port.
  • The port is configured with BPDU Guard enabled.
  • Pluribus Networks switches supports BPDU Guard on Edge ports.
  • Link Flaps
  • There are too many link flaps for a configured interval of time.
  • MAC address Security Violation
  • The number of MAC addresses on an interface is greater than the configured limit.


This feature allows you to configure an automatic retry to enable the port after a configured timeout.
