Description: In an MSTP Bridge, the Configuration Digest in the MST Configuration Identifier.
What is ieee8021MstpConfigurationDigest?
A 16-byte MD5-style digest computed from the VLAN-to-MSTI mapping table, forming part of this bridge's MST Configuration Identifier; bridges compare this digest (along with name and revision level) to decide whether they belong to the same MSTP region — a mismatch here is a common cause of two switches unexpectedly ending up in separate regions.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.7.1.5 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpConfigurationDigest
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.7.1.5.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpConfigurationDigest.1
