rldot1sMstpInstancePortState

Module: RADLAN-BRIDGEMIBOBJECTS-MIB

OID (symbolic): RADLAN-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortState

OID (numeric): 1.3.6.1.4.1.89.57.6.2.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The port's current state as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the bridge has detected a port that is malfunctioning it will place that port into the broken(6) state. For ports which are disabled (see dot1dStpVlanPortEnable), this object will have a value of disabled(1).

What is rldot1sMstpInstancePortState?

This read-only object reports the current spanning-tree protocol state of a port within a specific MSTP (Multiple Spanning Tree Protocol) instance, such as disabled, blocking, learning, or forwarding. Network operators monitor this to understand data path topology and identify redundant or failed paths in bridged networks. If a port is malfunctioning, the switch automatically sets it to broken(6).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.89.57.6.2.1.4
snmpwalk -v2c -c public <target> RADLAN-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.89.57.6.2.1.4.1
snmpget -v2c -c public <target> RADLAN-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortState.1
