Release Information
Statement introduced in Junos OS Release 9.1 for EX Series switches.
Statement updated in Junos OS Release 9.4 for EX Series switches to add VSTP support. Statement updated in Junos OS Release 11.1 for EX Series switches to change blocking behavior to port shutdown.
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 to unblock and reenable the interface.
Default
Not enabled.
Required Privilege Level
