Module: ALCATEL-IND1-VLAN-STP-MIB
OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionCistInstanceNumber
OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.7
Node type: OBJECT-TYPE
Type: Integer32

Description: Number of the CIST instance. Always 0 in this release and limited to one region
What is vStpMstRegionCistInstanceNumber?
This read-only integer (always 0) identifies the Common and Internal Spanning Tree instance number. Network engineers see this as a placeholder; CIST (instance 0) is always present and manages inter-region STP, while MSTIs 1-63 handle intra-region VLAN groups.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.7 snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionCistInstanceNumber
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.7.1 snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionCistInstanceNumber.1
