Release Information

Statement introduced in Junos OS Release 12.2 for EX Series switches.

Description

Drop bridge protocol data units (BPDUs ) that enter any interface or a specified interface, but do not disable the interface. Configure the drop statement only on interfaces on which no spanning-tree protocol (STP, MSTP, or RSTP) is configured.

Note: Do not configure drop on any interface on which a spanning-tree protocol has been configured. Doing so could cause STP misconfiguration and consequent network outages.
