Description: Provides management objects specific to Cisco Catalyst Network Office switches, covering port configuration and switch fabric status.

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-CNO-SWITCH-MIB?

CISCO-CNO-SWITCH-MIB manages Cisco Network Office (CNO) switch products, a switch line providing system identity, configuration, and port-level management. It exposes hardware identity information (serial number, board revision, boot version, address table capacity), system-level configuration and reset controls, monitor-port configuration for port mirroring, and a per-port table including controller revision and port naming. Its monitoring emphasis is hardware/software identity and configuration status: administrators use it to inventory installed hardware revisions and boot software versions, and to verify monitor-port (SPAN-like) configuration is correctly set for diagnostic packet capture. It is a vendor-specific management module without an explicit stated dependency on other Cisco MIBs, though it complements standard IF-MIB port data. It is deployed on Cisco CNO switches used in small-to-midsize network office deployments. Engineers can download the CISCO-CNO-SWITCH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-CNO-SWITCH-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 cnosSysInfoSerialNo, cnosSysInfoBoardRevision, and cnosSysInfoBootVersion to inventory the switch's hardware and boot firmware version, and check cnosSysConfigMonitor and cnosSysConfigMonitorPort to confirm which port is configured as a monitoring/SPAN destination. Reviewing cnosPortTable entries for cnosPortControllerRevision across ports would help identify a port with a mismatched or outdated controller revision that could explain inconsistent link behavior.

What Can Be Monitored

hardware serial number and board revision
boot software version
monitor/SPAN port configuration
per-port controller revision and naming
address table capacity
system reset/default reset status

Setting this object to noReset(1) has no effect. The switch always returns the value noReset(1) when this object is read.
INT cnosSysConfigDefaultReset	1.3.6.1.4.1.9.10.43.1.2.2	INTEGER	read-write	Setting this object to reset(2) causes a complete reset of both hardware and software, but does not run the POST (Power On Self Test). All configuration parameters will revert to their factory default settings, and all addresses assigned will be removed. Setting this object to noReset(1) has no effect. The switch always returns the value noReset(1) when this object is read.
INT cnosSysConfigMonitor	1.3.6.1.4.1.9.10.43.1.2.3	INTEGER	read-write	Selects whether frames to/from certain ports are sent to conSwitchSysConfigMonitorPort. A port is selected for monitoring purpose when its cnosPortMonitoring object is set to enabled.
I32 cnosSysConfigMonitorPort	1.3.6.1.4.1.9.10.43.1.2.4	Integer32	read-write	Port number to which all frames to/from monitored ports are sent. Frames are only monitored if the sysConfigMonitor object is set to enabled(1). A number from 1 to 8 selects a switch port. The number 0 selects no monitor port.
cnosPort	1.3.6.1.4.1.9.10.43.1.3
cnosPortTable	1.3.6.1.4.1.9.10.43.1.3.1		not-accessible	A list of configuration entries for individually switched ports. There in one entry created automatically for each switch port (ifType of ethernetCsmacd) on the device.

INT cnosPortSpeedStatus	1.3.6.1.4.1.9.10.43.1.3.1.1.6	INTEGER	read-only	The operating speed of the switched port.
INT cnosPortMonitoring	1.3.6.1.4.1.9.10.43.1.3.1.1.7	INTEGER	read-write	Set to enabled(1) to forward receive and transmit frames on this port to the port identified by cnosSysConfigMonitorPort. Set to disabled(2) to not monitor frame traffic on this port.
INT cnosPortLinkStatus	1.3.6.1.4.1.9.10.43.1.3.1.1.8	INTEGER	read-only	The current port link status.
INT cnosPortSTPPortFastMode	1.3.6.1.4.1.9.10.43.1.3.1.1.9	INTEGER	read-write	This object configures the port into the Spanning Tree port-fast mode. When enabled(1), the STP can transition the port's state directly from blocking to forwarding, and vice versa, without going through the intermediate listening and learning states. This object should only be enabled for a port that is connected to a single workstation. A port that is attached to a network segment with multiple network nodes or bridges should have this object set to disabled(2) since a temporary loop may occur when port changes state.
INT cnosPortVlanMember	1.3.6.1.4.1.9.10.43.1.3.1.1.10	INTEGER	read-write	Set the port to be a member of a specified VLAN. Set the port to all(5) to be shared among all VLANs.
