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
l The port is set to err-disabled when a BPDU Guard message is received on an Edge port.
l The port is configured with BPDU Guard enabled.
l Pluribus Networks switches support BPDU Guard on Edge ports.
Link Flaps
l There are too many link flaps for a configured interval of time.
MAC address Security Violation
l The number of MAC addresses on an interface is greater than the configured limit.
l This feature allows you to configure an automatic retry to enable the port after a configured timeout.
