jnxMIMstCistPortLoopProtectEnabled

Module: JUNIPER-MIMSTP-MIB

OID (symbolic): JUNIPER-MIMSTP-MIB::jnxMIMstCistPortLoopProtectEnabled

OID (numeric): 1.3.6.1.4.1.2636.3.46.1.1.8.1.3

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: A Boolean value set by management indicating whether Loop protect functionality is enabled on the port. If TRUE causes the Port not to be selected as Designated Port for the CIST or any MSTI, when the received superior BPDU is aged out. This parameter should be FALSE by default.

What is jnxMIMstCistPortLoopProtectEnabled?

Whether Loop Protect is enabled on this port for the Common Spanning Tree (default false); when true, the port is prevented from becoming a Designated Port if the superior BPDU it was relying on ages out, guarding against a loop forming from a lost BPDU stream. Admins enable this on ports where a link failure in one direction could otherwise silently create a bridging loop.
