jnxDot1dStpPortRootProtectEnabled
Module: JUNIPER-L2CP-FEATURES-MIB
OID (symbolic): JUNIPER-L2CP-FEATURES-MIB::jnxDot1dStpPortRootProtectEnabled
OID (numeric): 1.3.6.1.4.1.2636.3.53.1.1.1.1.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: A Boolean value set by management indicating whether Root protect functionality is enabled on the port. If TRUE causes the Port not to be selected as Root Port, even it has the best spanning tree priority vector. This parameter should be FALSE by default.
What is jnxDot1dStpPortRootProtectEnabled?
This object indicates whether Root Protect is enabled on this STP port, a feature that prevents the port from ever being elected the spanning tree Root Port, even if it presents the best priority vector. Admins enable this on ports facing untrusted or edge devices to stop a rogue or misconfigured switch from taking over as the root bridge. For example, enabling Root Protect on an access-facing uplink port ensures a customer device sending a superior BPDU can't hijack the root role for the whole spanning tree.
