mtaGroupHierarchy
Module: MTA-MIB
OID (symbolic): MTA-MIB::mtaGroupHierarchy
OID (numeric): 1.3.6.1.2.1.28.2.1.31
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Describes how this group fits into the hierarchy. A positive value is interpreted as an mtaGroupIndex value for some other group whose variables include those of this group (and usually others). A negative value is interpreted as a group collection code: Groups with common negative hierarchy values comprise one particular breakdown of MTA activity as a whole. A zero value means that this MIB implementation doesn't implement hierarchy indicators and thus the overall group hierarchy cannot be determined.
What is mtaGroupHierarchy?
Describes how this group fits into a larger hierarchy of groups: a positive value points to the index of a parent group whose totals include this one, a negative value marks a shared grouping scheme, and zero means the MTA doesn't expose hierarchy at all — an admin uses this to understand whether summing groups will double-count.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.28.2.1.31 snmpwalk -v2c -c public <target> MTA-MIB::mtaGroupHierarchy
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.28.2.1.31.1 snmpget -v2c -c public <target> MTA-MIB::mtaGroupHierarchy.1
