vStpMstRegionConfigDigest
Module: ALCATEL-IND1-VLAN-STP-MIB
OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionConfigDigest
OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.3
Node type: OBJECT-TYPE
Type: DigestId
Access: read-only
Description: The Mst Region identifier, a 16 octet field of type HMAC-MD5. It is an encoding of the VID to MSTID table and sent in the MSTP BPDU to allow bridges to recognize their neighbors region.
What is vStpMstRegionConfigDigest?
This read-only 16-octet HMAC-MD5 digest uniquely identifies the MSTP region configuration, allowing bridges to recognize peers. Network engineers verify matching digests on all bridges in a region to ensure consistent VLAN-to-MSTI mappings. Mismatches cause STP to treat regions as separate trees.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.3 snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionConfigDigest
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.4.1.3.1 snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpMstRegionConfigDigest.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> vStpMstRegionConfigDigest.1
