errdisable detect cause bpduguard Configures the port to be shut down or moves the port to blocked state on detecting a BPDU guard violation. Syntax errdisable detect cause bpduguard Parameters None Default Enabled Command Mode CONFIGURATION Usage Information This command applies only to STP-enabled ports. The command takes effect only when the BPDU guard is configured on a port. When the detect cause option is enabled, the port is shut down whenever there is a BPDU guard violation. When the option is disabled, the port is not shut down but moved to BLOCKING state whenever there is a BPDU guard violation. In this case, the port is operationally DOWN in spanning-tree mode and when the recovery timer expires after 300 seconds, the port is UP irrespective of the recovery cause configuration. The no version of the command disables the detect cause option. Example OS10(config)# errdisable detect cause bpduguard Supported Releases 10.4.2.0 or later errdisable recovery cause bpduguard Enables to recover the ports shut down due to BPDU Guard violation. Syntax errdisable recovery cause bpduguard Parameters None Default Disabled Command Mode CONFIGURATION Usage Information This command applies only to STP-enabled ports.

When the recovery option is enabled, the port is brought up after the recovery timer expires. When the recovery option is disabled, the port is shut down indefinitely. You must manually bring up the port using the shutdown and no shutdown commands. The no version of the command disables the recovery option. Example OS10(config)# errdisable recovery cause bpduguard Supported Releases 10.4.2.0 or later errdisable recovery interval Configures recovery interval timer to delay the recovery of ports when there is a BPDU Guard violation. Syntax errdisable recovery interval interval-value Parameters interval-value-Enter the time interval in seconds. The range is from 30 to 65535.
