Description: The Vlan group number that the port belongs to, and for which this entry contains Spanning Tree Protocol management information.
What is rldot1sMstpInstancePortMstiId?
This object identifies the Multiple Spanning Tree Instance (MSTI) group number that a network port belongs to within a bridge. It is used to organize and manage VLAN groups when running Multiple Spanning Tree Protocol, allowing different VLANs to be grouped together for independent spanning tree calculations. An operator would query this to understand which spanning tree instance a particular port participates in for topology protection and loop prevention.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.89.57.6.2.1.1 snmpwalk -v2c -c public <target> Dell-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortMstiId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.89.57.6.2.1.1.1 snmpget -v2c -c public <target> Dell-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortMstiId.1
