Configuring Auto-Recovery of a Disabled Port


Netvisor ONE automatically disables physical ports 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 becomes a security violation.


However, Netvisor ONE does not indicate the down port as 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.
