errdisable detect cause
Use the errdisable detect cause global configuration command on the switch stack or on a standalone
switch to enable error-disabled detection for a specific cause or all causes. Use the no form of this
command to disable the error-disabled detection feature.

For the BPDU guard and port-security features, you can use this command to globally configure the
switch to shut down just the offending VLAN on the port when a violation occurs, instead of shutting
down the entire port.

down the entire port.
When the per-VLAN error-disable feature is turned off and a BPDU guard violation occurs, the entire
port is disabled. Use the no form of this command to disable the per-VLAN error-disable feature.
