CISCO-PORT-TRACK-MIB
The CISCO-PORT-TRACK-MIB manages Cisco switch link-state dependencies by configuring the `cptPortTrackTable` to associate tracked ports with tracking ports, triggering forced shutdowns via `cptPortForceShutTable` when upstream link failures occur to prevent end-device connectivity issues. This mechanism monitors operational status changes to propagate link-down events directly to dependent access ports, ensuring immediate service isolation during indirect network failures.

ciscoPortTrackMIBA MIB to configure the Port-Track feature.
When a link goes down, all the services which depend
on the link are notified of the outage. The loss of
this link may be an indirect failure to the end devices
attached to the switch. The concept behind the Port-Track
feature is to create a direct failure on the ports
connected to end devices on event of such indirect
failures.
One more ports can be 'tracked' in terms of their
operational status. The cptPortTrackTable lets the user
associate which port(s) need to be tracked to the ports
that will be tracking them.
cptPortForceShutTable, lets the user configure the
forced-shut mode of the linked-port. MODULE-IDENTITY .1.3.6.1.4.1.9.9.437 |

cptPortTrackTableA table listing the linked ports and the configurations
of their associated tracked ports. The configuration of
each tracked port includes its interface index as well
as a VSAN index if only one VSAN is to be tracked. SEQUENCE OF CptPortTrackEntry .1.3.6.1.4.1.9.9.437.1.1.1 |
cptPortTrackEntryAn entry in the cptPortTrack Table. CptPortTrackEntry .1.3.6.1.4.1.9.9.437.1.1.1.1 |
cptPortTrackLinkedPortThe ifIndex of the port that will be tracking the
cptPortTrackTrackedPort. InterfaceIndex (IF-MIB) .1.3.6.1.4.1.9.9.437.1.1.1.1.1 |
cptPortTrackTrackedPortThe ifIndex of the port that needs to be tracked. InterfaceIndex (IF-MIB) .1.3.6.1.4.1.9.9.437.1.1.1.1.2 |
cptPortTrackVsanTypeThis objects denotes whether a single VSAN is
being tracked on cptPortTrackTrackedPort or
all the VSANs on that port are tracked.
If the set to 'singleVsan', then the VSAN
that will be tracked will be denoted by the
instance of cptPortTrackVsanIndex.rw Enumeration .1.3.6.1.4.1.9.9.437.1.1.1.1.3 |
cptPortTrackVsanIndexValid only if the instance of cptPortTrackVsanType
is 'singleVsan'. If cptPortTrackVsanType is
'allVsans', the instance of this object is
irrelevant.rw VsanIndex (CISCO-ST-TC) .1.3.6.1.4.1.9.9.437.1.1.1.1.4 |
cptPortTrackRowStatusThis object is used to create or delete the row.
When creating a row, the object cptPortTrackVsanType
must be specified. If the value of
cptPortTrackVsanType is 'singleVsan' then the
object cptPortTrackVsanIndex also must be
specified. If the value of cptPortTrackVsanType
is 'allVsans', then cptPortTrackVsanIndex should
not be specified in the create request.rw RowStatus (SNMPv2-TC) .1.3.6.1.4.1.9.9.437.1.1.1.1.5 |
cptPortForceShutTableA table to configure the forced-shut state
for each linked port. SEQUENCE OF CptPortForceShutEntry .1.3.6.1.4.1.9.9.437.1.1.2 |
cptPortForceShutEntryAn entry in the cptPortForceShutTable. CptPortForceShutEntry .1.3.6.1.4.1.9.9.437.1.1.2.1 |
cptPortForceStateThe forced-shut state of the linked port.
When all the tracked ports corresponding to
cptPortTrackLinkedPort, go down, cptPortTrackLinkedPort
is brought down. The cptPortForceState, determines
the manner in which this operation is performed.
If 'false', cptPortTrackLinkedPort is brought down
operationally only and is brought up again as
soon as any one of the tracked ports comes up.
If 'true', cptPortTrackLinkedPort is brought down
administratively as well and the user has to
manually bring the port up. i.e. the ifAdminStatus
cptPortTrackLinkedPort needs to be set to 'up'
by the user.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.437.1.1.2.1.1 |

This mapping ensures that SNMP management systems can accurately correlate physical inventory entries with vendor-specific component definitions for accurate device discovery and monitoring.
The CISCO-UNIFIED-COMPUTING-EQUIPMENT-MIB provides SNMP-based monitoring and management of Cisco Unified Computing System (UCS) hardware components, including chassis, blades, fabric interconnects, and power supplies. It exposes critical operational metrics such as device status, port states, temperature readings, fan speeds, and power consumption data for infrastructure health assessment.
The CISCO-UNIFIED-COMPUTING-ADAPTOR-MIB enables SNMP-based monitoring and management of physical and virtual network adapter interfaces, including link status, traffic counters, error statistics, and port configuration parameters, within the Cisco Unified Computing System (UCS) fabric interconnects and blade servers.
The CISCO-UNIFIED-COMPUTING-TC-MIB module defines standard textual conventions and data type definitions required for monitoring Cisco Unified Computing System (UCS) hardware components, including server blades, fabric interconnects, and chassis resources. These definitions enable consistent interpretation of specific UCS metrics such as power supply status, fan speeds, thermal readings, and port utilization across SNMP management applications.
The CISCO-UNIFIED-COMPUTING-FABRIC-MIB enables SNMP-based monitoring and management of the Cisco UCS Fabric Interconnects and associated fabric switching infrastructure, exposing metrics for port states, link utilization, error counters, and fabric topology status. It facilitates granular visibility into the physical and logical fabric layers, including uplink/downlink interfaces, VLAN configurations, and fabric failover conditions within the unified computing environment.
The STARENT-MIB module provides SNMP management and monitoring capabilities for Cisco ASR 5000 and ASR 5500 multimedia core platforms, specifically exposing metrics related to 2G/3G/4G and WiFi subscriber sessions, inline service states, and carrier-class high-availability status.
