Errdisable Detect Cause - Cisco Catalyst 2960 Command Reference Manual

errdisable detect cause

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