etsysIetfBridgeDot1dStpLoopProtectPortCistBlocking

Module: ENTERASYS-IETF-BRIDGE-MIB-EXT-MIB

OID (symbolic): ENTERASYS-IETF-BRIDGE-MIB-EXT-MIB::etsysIetfBridgeDot1dStpLoopProtectPortCistBlocking

OID (numeric): 1.3.6.1.4.1.5624.1.2.31.1.6.1.1.2

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The state of the port on the CIST with respect to the Loop Protect feature.

true(1) - this port is being held in the blocking state by the Loop Protect feature.

false(2) - this port is not being held in the blocking state by the Loop Protect feature.

When this object has a value of true(1) setting its value to false(2) will cause the Loop Protect feature to no longer hold the port in the blocking state.

All other set operations on this object are undefined and MUST NOT have any effect.

What is etsysIetfBridgeDot1dStpLoopProtectPortCistBlocking?

This read-write boolean reports and controls whether Loop Protect is currently holding this port blocked; setting it from true to false releases the port from the Loop Protect block.
