Description
Configures bridge protocol data unit (BPDU) protection on a specified interface or on all interfaces. If the interface receives incompatible BPDUs, it is disabled.
If the disable-timeout statement is included in the BPDU
configuration, the interface is automatically reenabled after the
timer expires. Otherwise, you must use the operational mode command clear ethernet-switching bpdu-error interface to unblock and reenable the interface.
The remaining statements are explained separately. See CLI Explorer.
