Description
Configure bridge protocol data unit (BPDU) protection
on all edge ports of a switch. When the bpdu-block-on-edge statement is configured and the interface encounters an incompatible
BPDU, the interface shuts down.
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.
Default
Not enabled.
Required Privilege Level
