Description: Manages platform-specific hardware and software parameters on Cisco Catalyst 2900 switches.

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-C2900-MIB?

CISCO-C2900-MIB is a Cisco enterprise MIB providing platform-specific management for the Catalyst 2900 series Ethernet switches. It exposes hardware inventory data (board revision, board identifier), buffer memory usage statistics, MAC address table capacity, and switch configuration options like broadcast storm alarms and address violation actions. It is explicitly useful for monitoring hardware health and software status: c2900InfoSelfTestFailed reports self-test/POST failures, c2900InfoRedunantPowerSupplyInfo reports redundant power supply presence/state, c2900InfoPeakBuffersUsed and c2900InfoTotalBufferDepth reveal buffer exhaustion pressure, and c2900InfoVisualIndicatorMode relates to front-panel LED/status indication. It is a Cisco-proprietary MIB with no strong dependency on other standard MIBs beyond standard SNMPv2 SMI conventions. It is typically deployed on legacy Catalyst 2900 series switches in wiring-closet or small campus network environments. Network administrators supporting older cisco c2900 series switches sometimes still reference this MIB when auditing legacy wiring-closet deployments.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-C2900-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.

Cisco Catalyst 2900 series switch

Monitoring Examples

An admin would poll c2900InfoSelfTestFailed to detect a failed hardware self-test and c2900InfoRedunantPowerSupplyInfo to confirm a redundant power supply is present and healthy on a Catalyst 2900 chassis. Watching c2900InfoPeakBuffersUsed relative to c2900InfoTotalBufferDepth over time reveals buffer congestion that could precede packet drops. c2900ConfigBroadcastStormAlarm configuration combined with alarm state can flag a broadcast storm event affecting the switch.

What Can Be Monitored

board self-test failure status
redundant power supply status
buffer utilization
MAC address table capacity
broadcast storm alarm state
board revision/identifier

How to Use in IPNetwork Monitor

Example using c2900PortAddrSecureAddrViolations OID:

Select a Cisco Catalyst 2900 series switch (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type c2900PortAddrSecureAddrViolations into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of times a source address seen on this port duplicates a secured address configured on another port, or doesn't match any address secured for this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
NTF c2900AddressViolation	1.3.6.1.4.1.9.9.87.2.0.1			The addressViolation notification is generated when an address violation is detected on a secured port. The generation of the addressViolation notification can be enabled or suppressed using the object c2900ConfigAddressViolationAction. The particular secured port is indicated by the value of c2900PortIfIndex.
c2900BandwidthUsage	1.3.6.1.4.1.9.9.87.1.5
G32 c2900BandwidthUsageCurrent	1.3.6.1.4.1.9.9.87.1.5.1	Gauge32	read-only	The current bandwidth consumed. The measurement unit is in megabits per second (1,000,000 bits/second). This value gives a reasonable estimate of the amount of traffic currently flowing through the switch. It is calculated as follows: Octets8 + Frames(96 + 64) --------------------------- Measurement Interval * 1,000,000 * 2 Where: Measurement Interval is the amount of time over which the Octets and Frames were collected, in seconds. Measurement Interval is always one second in current implementation. Octets is the total number of octets transmitted or received by all network interfaces, excluding framing data but including FCS. This includes octets in frames which were partially transmitted or received (due to collisions, for example). Frames is the total number of frames transmitted or received by all network interfaces, including frames with errors. The number of frames is multiplied by 96 plus 64 in order to estimate the delay between each frame for Ethernet's IPG and preamble/SFD. The '2' in the divisor makes this a forwarding bandwidth counter. A frame received on one interface is typically forwarded out another interface. In order to avoid double- counting this frame's bandwidth, once on the receiving interface and once on the transmitting interface, the total bandwidth is divided by two. Since multicast and broadcast frames can be sent to multiple ports, the above is at best a lower bound.
G32 c2900BandwidthUsageCurrentPeakEntry	1.3.6.1.4.1.9.9.87.1.5.5	Gauge32	read-only	A value identifying an instance of the c2900BandwidthUsagePeakIndex where the peak bandwidth estimation is most recent.

G32 c2900BandwidthUsagePeak	1.3.6.1.4.1.9.9.87.1.5.6.1.3	Gauge32	read-only	The maximum bandwidth usage of any measurement interval within this recording interval. This value is an estimate of the highest amount of traffic flowing through the switch during this recording interval. It is calculated as follows: Octets8 + Frames(96 + 64) --------------------------- Measurement Interval * 1,000,000 * 2 Where: Measurement Interval is the amount of time over which the Octets and Frames were collected, in seconds. Measurement Interval is always one second in c2900's implementation. Octets is the total number of octets transmitted or received by all network interfaces, excluding framing data but including FCS. This includes octets in frames which were partially transmitted or received (due to collisions, for example). Frames is the total number of frames transmitted or received by all network interfaces, including frames with errors. The number of frames is multiplied by 96 plus 64 in order to estimate the delay between each frame for Ethernet's IPG and preamble/SFD. The '2' in the divisor makes this a forwarding bandwidth counter. A frame received on one interface is typically forwarded out another interface. In order to avoid double- counting this frame's bandwidth, once on the receiving interface and once on the transmitting interface, the total bandwidth is divided by two. Since multicast and broadcast frames can be sent to multiple ports, the above is at best a lower bound.

Setting the object to false(2) disallows such control. The buffer congestion control algorithm is summarized in the description of the c2900PortBufferCongestionThresholdPercent below. This object is deprecated
I32 c2900PortBufferCongestionThreshholdPercent	1.3.6.1.4.1.9.9.87.1.4.1.1.8	Integer32	read-only	The port buffer congestion threshold provides an early warning to the switch that the port is about to exhaust all its guaranteed buffers, leading to congestion. This threshold is expressed as a percentage of the port's total guaranteed buffer depth. Once this threshold has been crossed, the switch begins colliding with frames received on the port for a fixed period of time. After this time has expired, the switch determines whether the port's buffer congestion has been alleviated. If this situation has not changed, the switch resumes this congestion control algorithm on the port.

Set to halfduplex(2) to operate in half duplex mode. Set to autoNegotiate(3) to allow the switch to negoti- ate with the other end of the connection. The status of duplex mode on a port is available with c2900PortDuplexStatus object.
INT c2900PortDuplexStatus	1.3.6.1.4.1.9.9.87.1.4.1.1.32	INTEGER	read-only	The status of duplex mode on this port. When linkbeat is not present, halfduplex is always reported. When linkbeat is present, the result of full duplex auto-negotiation is reported if c2900PortDuplexState is set to auto-negotiate, otherwise it reports fullduplex if c2900PortDuplexState is set to fullduplex or halfduplex if c2900PortDuplexState is set to halfduplex.
c2900PortEntry	1.3.6.1.4.1.9.9.87.1.4.1.1		not-accessible	Entry containing information for a particular switched port on a module installed. The entries are not created or deleted by management commands.

INT c2900PortLinkbeatStatus	1.3.6.1.4.1.9.9.87.1.4.1.1.18	INTEGER	read-only	This object depends on the physical layer in use and indicates the current port linkbeat status: if the physical link between two devices is properly connected or not. If the value is linkbeat(1), there is linkbeat. If the value is nolinkbeat(2), there is no linkbeat. If the value is unknown(3), the information is not available.
T/F c2900PortMayForwardFrames	1.3.6.1.4.1.9.9.87.1.4.1.1.6	TruthValue	read-write	This object reflects an internal state of the port with regard to its ability to forward frames. A port sometimes stops forwarding frames when it is blocked by the Spanning Tree Protocol, or while it is undergoing temporary load balancing as part of the port grouping usage. This object is true(1) if the port is allowed to forward frames. It is false(2) otherwise. Setting this object to true(1) will fail, if the port is in the middle of being blocked by the Spanning Tree Protocol, or while it is undergoing temporary load balancing as part of the port grouping usage. This object is only supported for static VLAN access ports.
T/F c2900PortMayLearnAddress	1.3.6.1.4.1.9.9.87.1.4.1.1.5	TruthValue	read-write	This object reflects an internal state of the port with regard to its ability to learn new addresses. Certain port configurations such as learning time limit, security usage, etc., and some Spanning Tree Protocol states can temporarily prohibit the port from learning. This object is true(1) if the port is allowed to learn. It is false(2) otherwise. Setting this object to true(1) will fail, if the port is not in normal state. This object is deprecated.

A value of zero can't be used to do set, it is used to return when this object is read. To remove a port from the monitored list use the object c2900PortNoMonitorDestinationPort.
OCT c2900PortMonitoredPortMap	1.3.6.1.4.1.9.9.87.1.4.1.1.30	OCTET STRING	read-only	Indicates which ports are actually being monitored. The octet string contains one bit per port. Each bit within the octet string represents one port of the device. The ordering of ports represented within the octet string is in the same order as in the RFC 1493 dot1dStaticAllowedToGoTo in the dot1dStaticTable. The bit value interpretation is as follows: 1 = being monitored 0 = not being monitored
I32 c2900PortNoMonitorDestinationPort	1.3.6.1.4.1.9.9.87.1.4.1.1.34	Integer32	read-write	Switch Port (c2900PortSwitchPortIndex) index value of the port that is to be removed from the monitored list. A value of zero can't be used to do set, it is used to return when this object is read. To add a port to the monitored list use the object c2900PortMonitorDestinationPort.
C32 c2900PortNumberOfDroppedAddresses	1.3.6.1.4.1.9.9.87.1.4.1.1.14	Counter32	read-only	The number of times an address could not be learned or assigned for the port because its address table was full at one time.
C32 c2900PortNumberOfLearnedAddresses	1.3.6.1.4.1.9.9.87.1.4.1.1.13	Counter32	read-only	The current number of dynamically learned addresses on the port.
C32 c2900PortRxFcsErrFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.6	Counter32	read-only	The total number of frames received with FCS errors. This total includes all frames received with an FCS error and an integral number of bytes. Unlike RFC1650's dot3StatsFCSErrors, this object does not include frames which are less than the minimum packet size (such as collision fragments).
C32 c2900PortRxNoBufferFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.2	Counter32	read-only	A count of frames received that were discarded due to a lack of frame buffer resources in the Catalyst Switch forwarding engine.
C32 c2900PortRxNoBwFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.1	Counter32	read-only	A count of frames received on this port that were discarded due to a lack of bandwidth resources in the Catalyst Switch forwarding engine.
C32 c2900PortRxNoDestMultiFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.4	Counter32	read-only	A count of multicast frames received that were discarded, because they have not been configured for the port.
C32 c2900PortRxNoDestUniFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.3	Counter32	read-only	A count of unicast frames received that were discarded, because the forwarding rules stipulate that they are not be forwarded.
C32 c2900PortRxSuppressBcastFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.5	Counter32	read-only	A count of broadcast frames received that were discarded because of the threshold-based broadcast suppression. This object is deprecated, because there is no way that the Malibu system to give the brodcast_supress frames
INT c2900PortSpantreeFastStart	1.3.6.1.4.1.9.9.87.1.4.1.1.36	INTEGER	read-write	Indicates whether the port is operating in spantree fast start mode. A port with fast start enabled is immediately put in spanning tree forwarding state on link up, rather than starting in blocking state which is the normal operation. This is useful when the port is known to be connected to a single station which has problems waiting for the normal spanning tree operation to put the port in forwarding state.
c2900PortStatsEntry	1.3.6.1.4.1.9.9.87.1.4.2.1		not-accessible	Entry containing information for a particular switched port on a module installed. The entry cannot be created or deleted.

c2900PortStatsGroupRev1	1.3.6.1.4.1.9.9.87.3.2.14			The collection of objects which are used to provide port stats.
c2900PortStatsGroupSA3	1.3.6.1.4.1.9.9.87.3.2.8			The collection of objects which are used to provide port stats.
c2900PortStatsTable	1.3.6.1.4.1.9.9.87.1.4.2		not-accessible	A list of port entries. The number of entries is determined by the number of modules in the chassis and the number of ports on each module.
INT c2900PortStatus	1.3.6.1.4.1.9.9.87.1.4.1.1.22	INTEGER	read-only	The port's current state as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the switch has detected a port that is malfunctioning it will place that port into the broken(10) state. For ports which are disabled(see dot1dStpPortEnable), this object will have a value of disabled(2). Since the switch implements three additional states which are not part of IEEE Standard, these additional states are possible values for c2900PortStaus. The additional states are preforwarding(6), secureforwarding(8), and suspended(9). Note: except for these additional states, this object is the same as the dot1dStpPortState object. Default value: blocking(2). This object is only supported for static VLAN access ports.
I32 c2900PortSwitchPortIndex	1.3.6.1.4.1.9.9.87.1.4.1.1.29	Integer32	read-only	Switch port index of a port is a value that uniquely identifies the port within a switch. This is obtained from the port index (c2900PortIndex) and the module index (c2900PortModuleIndex).
c2900PortTable	1.3.6.1.4.1.9.9.87.1.4.1		not-accessible	A list of port entries. The number of entries is determined by the number of modules in the chassis and the number of ports on each module.
T/F c2900PortTestResult	1.3.6.1.4.1.9.9.87.1.4.1.1.23	TruthValue	read-only	This object indicates if the port passed power on self test or not. If the value of this object is true(1), the port passed test. If the value of this object is false(2), the port failed test.
C32 c2900PortTxBroadcastFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.9	Counter32	read-only	A count of frames that are successfully transmitted and are directed to the broadcast address. Unlike RFC1573's ifOutBroadcastPkts, this object does not include those that were discarded or not sent.
C32 c2900PortTxMulticastFrames	1.3.6.1.4.1.9.9.87.1.4.2.1.8	Counter32	read-only	A count of frames that are successfully transmitted and are directed to a multicast address. Unlike RFC1573's ifOutMulticastPkts, this object does not include those that were discarded or not sent.
INT c2900PortUsageApplication	1.3.6.1.4.1.9.9.87.1.4.1.1.3	INTEGER	read-write	This object indicates how the port is to be used. The variable usage applications are shown above. These applications are defined such that they are mutually exclusive. In other words, a port using the security(2) application cannot also use the monitor(3) application at the same time. The default usage is standard(1), or no special behavior (the port behaves as normal switched port). The security(2) usage adds addressing security to the port, whereby all learned addresses are secure address. The monitor(3) usage provides network diagnosis by reflecting traffic on other ports to this port. The portGrouping(4) application treats this and other ports in the same group as one(inter-switch) connection for more bandwidth potential. When the c2900PortUsageApplication is portGrouping, the c2900PortGroupIndex is set to the index value of the port group. The source address of a received frame is used to determine on which port within the group the frame should be transmitted. The network(5) usage saves address table space when the port is used as the link to a large network with many MAC addresses by disabling address learning on the port and allowing unknown unicasts packets received on other ports of the vlan the port associated with to be forwarded only to the port. The networkGroup(6) usage treates this and other ports in the same group as a network port group. All ports in port are network ports in the sense that address learning is disabled on them and unknown unicast packets received on other ports of the vlan are forwarded to the group. The portGroupDest(7) application treats this and other ports in the same group as one(inter-switch) connection for more bandwidth potential. When the c2900PortUsageApplication is portGroupDest, the c2900PortGroupIndex is set to the index value of the port group. The destination address of a received frame is used to determine on which port within the group the frame should be transmitted. The protected(8) application does not forward any traffic to other protected ports. It does not forward all kinds of unicast, multicast and broadcast traffic to any other protected port. The protected ports, however, forward traffic normally to non-protected ports and vice versa.
INT c2900PortVisualIndicator	1.3.6.1.4.1.9.9.87.1.4.1.1.24	INTEGER	read-only	This object is used to indicate the current color of a LED. If a LED is flashing, the value of this object will represent the color of the LED at that instant in time. The following conventions indicate port status: Link healthy returns green(4) Link activity usually green(4), but may return black(2). Link faulty alternating green(4)/amber(3) Port disabled returns amber(3)
INT c2900PortVoiceVlanId	1.3.6.1.4.1.9.9.87.1.4.1.1.37	INTEGER	read-write	The Voice Virtual Vlan ID (VVID) to which this port belongs to. If the VVID is not supported on the port, this MIB object will not be configurable and will return 4096. Setting this MIB object to 4096, the CDP packets transmitting through this port would not include Appliance VLAN-ID TLV. Setting this MIB object to 4095, the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with value of 4095 - VoIP and related packets are expected to be sent and received untagged without an 802.1p priority. Setting this MIB object to 0, the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with value of 0 - VoIP and related packets are expected to be sent and received with VLAN-id=0 and an 802.1p priority. Setting this MIB object to N (1..1000), the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with N - VoIP and related packets are expected to be sent and received with VLAN-id=N and an 802.1p priority.
