Description: Manages Cisco StackMaker proprietary stacking protocol providing configuration and status for stacked switch clusters.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-STACKMAKER-MIB?

CISCO-STACKMAKER-MIB manages Cisco's proprietary StackMaker stacking protocol, an early mechanism for joining multiple Cisco switches into a single managed stack cluster. It exposes configuration and identity data such as the overall stack name, a table of per-unit IP addresses within the stack, and an action object to clear stack state. For monitoring purposes it lets an administrator confirm which physical units are currently members of a stack and verify each member's management IP address is reachable and correctly assigned, which is foundational to detecting a unit that has dropped out of the stack or been misconfigured. As a legacy Cisco-proprietary protocol, it does not appear to build on other standard MIBs, functioning independently of later stacking approaches such as CISCO-STACK-MIB. It is typically deployed on older Cisco Catalyst switch families that used StackMaker for physical switch stacking before being superseded by newer stacking technologies, where CISCO-STACKMAKER-MIB SNMP monitoring helped confirm all stack members remained present and reachable.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-STACKMAKER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator would poll csmStackTable/csmStackEntry, keyed by csmStackIndex, to enumerate each stacked unit's csmStackIpAddress and confirm all expected members are present alongside the overall csmStackName. If a unit's expected index is missing from the table, that member has dropped out of the stack and needs investigation. The csmClearStackTable object would be used administratively to reset stack membership state when reconfiguring the cluster.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoStackMakerMIB	1.3.6.1.4.1.9.9.59			The MIB module for Cisco Systems' StackMaker.
ciscoStackMakerMIBObjects	1.3.6.1.4.1.9.9.59.1
ciscoStackMakerConf	1.3.6.1.4.1.9.9.59.1.1
STR csmStackName	1.3.6.1.4.1.9.9.59.1.1.1	DisplayString	read-write	A descriptive string used by the network administrator one stack at any given time. If this entry is empty, the device is not a member of a stack. Changing the value of this object will move the device to a different stack. If the value is cleared, the device is no longer a member of any stack.
INT csmClearStackTable	1.3.6.1.4.1.9.9.59.1.1.2	INTEGER	read-write	This object is used to clear the csmStackTable with a single SNMP operation. The application will clear the table and re-write the table to accommodate new or modified table entries. Setting this object to noClearTable has no effect. The agent will always return the value of noClearTable when this object is read.
csmStackTable	1.3.6.1.4.1.9.9.59.1.1.3		not-accessible	The table of IP addresses for the devices which are members of the stack. Individual entries can be added to the table to add devices in the stack either through SNMP Set operations or through the device's command line interface. However, the agent need not support deletion of individual entries, since the table is first cleared before any modifications are made, using the csmClearStackTable object. The agent will return the error badValue if an SNMP Set operation is attempted on an existing row. It is the responsibility of the network administrator to ensure that a device does not belong to more than one stack and to maintain referential integrity across devices. A device will take no action upon the information stored in this table other than to guarantee its persistence over device reboots.
csmStackEntry	1.3.6.1.4.1.9.9.59.1.1.3.1		not-accessible	An entry for each device which is member of the stack.
INT csmStackIndex	1.3.6.1.4.1.9.9.59.1.1.3.1.1	INTEGER	not-accessible	Index in the StackMaker table. Entries should be consecutive since updating this table is made by first clearing the table and reconfiguring it.
IP csmStackIpAddress	1.3.6.1.4.1.9.9.59.1.1.3.1.2	IpAddress	read-create	IP Address of a stack member.
ciscoStackMakerMIBConformance	1.3.6.1.4.1.9.9.59.3
ciscoStackMakerMIBCompliances	1.3.6.1.4.1.9.9.59.3.1
ciscoStackMakerMIBCompliance	1.3.6.1.4.1.9.9.59.3.1.1			The compliance statement for Cisco Systems entities which implement the StackMaker model. Every Cisco stackable device must implement the StackMaker MIB.
ciscoStackMakerMIBGroups	1.3.6.1.4.1.9.9.59.3.2
ciscoStackMakerBasicGroup	1.3.6.1.4.1.9.9.59.3.2.1			A collection of objects providing identification for a Cisco Systems' entity which implements the StackMaker MIB.
