Description: Manages the CAPWAP protocol for centralized control and provisioning of wireless access points (WTPs), including WTP profiles, station ACLs, and radio event statistics.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CAPWAP-BASE-MIB with a free 30-day trial of IPNetwork Monitor.

What Is CAPWAP-BASE-MIB?

CAPWAP-BASE-MIB is an IETF standards-track MIB (RFC 5833) defining the base managed objects for CAPWAP (Control And Provisioning of Wireless Access Points), the protocol by which a wireless LAN controller (Access Controller, AC) centrally manages Wireless Termination Points (WTPs, i.e. thin access points). It exposes session-capacity and current-session-count objects for both WTPs and wireless stations, security policy options for the CAPWAP data and control channels (DTLS, authentication), a table of configured AC names with priority for WTP failover, and notifications for CAPWAP events. Its monitoring role covers both operational capacity/status (how many WTPs and stations are currently connected versus the licensed/configured limit) and software-level configuration (security policy in force), which together indicate whether the controller is nearing capacity or has WTPs failing to establish sessions. As a vendor-neutral IETF MIB it is designed to be implemented alongside CAPWAP protocol binding MIBs such as CAPWAP-DOT11-MIB for technology-specific details. It is deployed on wireless LAN controllers (Access Controllers) managing fleets of CAPWAP-based thin access points, consistent with the CAPWAP-BASE-MIB RFC that defines this base object set.

IPNetwork Monitor allows you to monitor SNMP objects defined in CAPWAP-BASE-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.

Supported Devices

wireless LAN controller (Access Controller) managing CAPWAP access points

Monitoring Examples

An operator would compare capwapBaseWtpSessions against capwapBaseWtpSessionsLimit, and capwapBaseStationSessions against capwapBaseStationSessionsLimit, to see if the controller is approaching its licensed capacity for access points or client stations. Reviewing capwapBaseAcNameListTable/capwapBaseAcNameListEntry entries (capwapBaseAcNameListName, capwapBaseAcNameListPriority) helps confirm WTPs are configured to fail over to backup controllers in the correct priority order. Checking capwapBaseDataChannelDTLSPolicyOptions and capwapBaseControlChannelAuthenOptions confirms whether the expected encryption/authentication policy is actually enforced on the CAPWAP tunnels.

What Can Be Monitored

current vs limit WTP sessions
current vs limit station sessions
DTLS/authentication policy in force
configured AC name list and failover priority

How to Use in IPNetwork Monitor

Example using capwapBaseFailedDTLSAuthFailureCount OID:

Select a Wireless LAN controllers managing CAPWAP access point 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 capwapBaseFailedDTLSAuthFailureCount into the Find box to locate it in the OID tree, then select it and click OK. Represents the number of failed DTLS session establishment attempts due to authentication failures. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

capwapBaseStats	1.3.6.1.2.1.196.1.4
capwapBaseStatsGroup	1.3.6.1.2.1.196.2.2.15			Objects used for collecting the CAPWAP protocol's statistics.
capwapBaseWirelessBindingEntry	1.3.6.1.2.1.196.1.2.4.1		not-accessible	A set of objects that displays the mapping between a specific WTP Virtual Radio Interface and a PHY radio, and the wireless binding type for the PHY radio.
OID capwapBaseWirelessBindingRadioId	1.3.6.1.2.1.196.1.2.4.1.1	CapwapBaseRadioIdTC	not-accessible	Represents the identifier of a PHY radio on a WTP, which is required to be unique on a WTP. For example, WTP A and WTP B use a same value of capwapBaseWirelessBindingRadioId for their first radio.
capwapBaseWirelessBindingTable	1.3.6.1.2.1.196.1.2.4		not-accessible	A table of objects that display the mappings between WTP Virtual Radio Interfaces and PHY radios, and the wireless binding type for each PHY radio. As capwapBaseWirelessBindingTable stores the mappings between PHY radios (Radio IDs) and the ifIndexes of WTP Virtual Radio Interfaces, the operator can get the ifIndex information by querying this table. Such a query operation SHOULD run from radio ID 1 to radio ID 31 according to [RFC5415], and stop when an invalid ifIndex value (0) is returned. Values of all objects in this table are persistent at restart/reboot.
INT capwapBaseWirelessBindingType	1.3.6.1.2.1.196.1.2.4.1.3	INTEGER	read-only	Represents the wireless binding type for the radio. The following enumerated values are supported: dot11(1) - IEEE 802.11 epc(3) - EPCGlobal
NUM capwapBaseWirelessBindingVirtualRadioIfIndex	1.3.6.1.2.1.196.1.2.4.1.2	InterfaceIndex	read-only	Represents the index value that uniquely identifies a WLAN Virtual Radio Interface. The interface identified by a particular value of this index is the same interface as identified by the same value of the ifIndex. Before WTPs contact the AC to get configuration, the operator configures WTP profiles for them. The creation of a WTP profile triggers the system to automatically create a specific number of WTP Virtual Radio Interfaces and add a new row object in the capwapBaseWirelessBindingTable without manual intervention. As most MIB modules use the ifIndex to identify an interface for configuration and statistical data (for example, the IEEE 802.11 MIB module [IEEE.802-11.2007]), it will be easy to reuse other wireless binding MIB modules through the WTP Virtual Radio Interface in the Centralized WLAN Architecture.
PHY capwapBaseWtpBaseMacAddress	1.3.6.1.2.1.196.1.2.3.1.3	PhysAddress	read-only	Represents the WTP's Base MAC Address, which MAY be assigned to the primary Ethernet interface. The instance of the object corresponds to the Base MAC Address sub-element in the CAPWAP protocol [RFC5415].
CAP capwapBaseWtpCurrId	1.3.6.1.2.1.196.1.2.3.1.1	CapwapBaseWtpIdTC	not-accessible	Represents the unique identifier of a WTP in running state.
INT capwapBaseWtpDiscoveryType	1.3.6.1.2.1.196.1.2.3.1.6	INTEGER	read-only	Represents how the WTP discovers the AC. The following enumerated values are supported: unknown(0) - Unknown staticConfig(1) - Static configuration dhcp(2) - DHCP dns(3) - DNS acRef(4) - AC referral Note that the CAPWAP field [RFC5415] modeled by this object takes zero as starting value; this MIB object follows that rule.

C32 capwapBaseWtpEventsStatsHwFailureCount	1.3.6.1.2.1.196.1.2.6.1.5	Counter32	read-only	Represents the number of times that a CAPWAP protocol connection with an AC has failed due to hardware-related reasons.
C32 capwapBaseWtpEventsStatsInitCount	1.3.6.1.2.1.196.1.2.6.1.2	Counter32	read-only	Represents the number of reboots that have occurred at the request of a CAPWAP protocol message, such as a change in configuration that requires a reboot or an explicit CAPWAP protocol reset request. Note that the CAPWAP field [RFC5415] modeled by this counter takes the value 65535 to indicate that the information is not available on the WTP. This MIB object does not follow this behavior, which would not be standard in SMIv2. If the WTP does not have the information, the agent will not instantiate the object.
INT capwapBaseWtpEventsStatsLastFailureType	1.3.6.1.2.1.196.1.2.6.1.8	INTEGER	read-only	Represents the failure type of the most recent WTP failure. The following enumerated values are supported: unsupported(0) - Not supported acInit(1) - The AC initiated linkFailure(2) - Link failure swFailure(3) - Software failure hwFailure(4) - Hardware failure otherFailure(5) - Other failure unknown(255) - Unknown (e.g., WTP doesn't keep track of info) Note that the CAPWAP field [RFC5415] modeled by this object takes zero as starting value; this MIB object follows that rule.
C32 capwapBaseWtpEventsStatsLinkFailureCount	1.3.6.1.2.1.196.1.2.6.1.3	Counter32	read-only	Represents the number of times that a CAPWAP protocol connection with an AC has failed due to link failures.

C32 capwapBaseWtpEventsStatsRebootCount	1.3.6.1.2.1.196.1.2.6.1.1	Counter32	read-only	Represents the number of reboots that have occurred due to a WTP crash. Note that the CAPWAP field [RFC5415] modeled by this counter takes the value 65535 to indicate that the information is not available on the WTP. This MIB object does not follow this behavior, which would not be standard in SMIv2. If the WTP does not have the information, the agent will not instantiate the object.
C32 capwapBaseWtpEventsStatsSwFailureCount	1.3.6.1.2.1.196.1.2.6.1.4	Counter32	read-only	Represents the number of times that a CAPWAP protocol connection with an AC has failed due to software-related reasons.

ROW capwapBaseWtpProfileRowStatus	1.3.6.1.2.1.196.1.2.1.1.19	RowStatus	read-create	This object is used to create, modify, and/or delete a row in this table. The value of capwapBaseWtpProfileName, capwapBaseWtpProfileWtpName and capwapBaseWtpProfileWtpLocation can be changed when this object is in state 'active' or in 'notInService'. The other objects in a row can be modified only when the value of this object in the corresponding conceptual row is not 'active'. Thus, to modify one or more of the objects in this conceptual row: a. change the row status to 'notInService' b. change the values of the row c. change the row status to 'active' The capwapBaseWtpProfileRowStatus may be changed to 'active' if the managed objects capwapBaseWtpProfileName, capwapBaseWtpProfileWtpMacAddress, capwapBaseWtpProfileWtpModelNumber, capwapBaseWtpProfileWtpName, and capwapBaseWtpProfileWtpLocation in the conceptual row have been assigned valid values. Deleting a WTP profile in use will disconnect the WTP from the AC. So the network management system SHOULD ask the operator to confirm such an operation. When a WTP profile entry is removed from the table, the corresponding WTP Virtual Radio Interfaces are also removed from the capwapBaseWirelessBindingTable and ifTable [RFC2863]. Also, the related object instances SHOULD be removed from the wireless binding MIB modules such as the IEEE 802.11 MIB module [IEEE.802-11.2007].
capwapBaseWtpProfileTable	1.3.6.1.2.1.196.1.2.1		not-accessible	A table of objects that configure WTP profiles for WTPs to be managed before they connect to the AC. An operator could change a WTP's configuration by changing the values of parameters in the corresponding WTP profile, then the WTP could get the new configuration through the CAPWAP control channel. Values of all read-create objects in this table are persistent at restart/reboot.
U32 capwapBaseWtpProfileWtpEchoInterval	1.3.6.1.2.1.196.1.2.1.1.13	Unsigned32	read-create	Represents the minimum time, in seconds, between sending Echo Request messages to the AC that the WTP has joined.

The following enumerated values are supported: limited(0) - Limited ECN support fullAndLimited(1) - Full and limited ECN support Note that the CAPWAP field [RFC5415] modeled by this object takes zero as starting value; this MIB object follows that rule.
INT capwapBaseWtpProfileWtpFallbackEnable	1.3.6.1.2.1.196.1.2.1.1.12	INTEGER	read-create	Represents whether to enable or disable automatic CAPWAP fallback in the event that a WTP detects its preferred AC and is not currently connected to it. The following enumerated values are supported: enabled(1) - The fallback mode is enabled disabled(2) - The fallback mode is disabled
IP capwapBaseWtpProfileWtpGateway	1.3.6.1.2.1.196.1.2.1.1.11	InetAddress	read-create	When capwapBaseWtpProfileWtpStaticIpEnable is true, it represents the gateway to be assigned to the WTP. The format of this IP address is determined by the corresponding instance of object capwapBaseWtpProfileWtpStaticIpType.
U32 capwapBaseWtpProfileWtpIdleTimeout	1.3.6.1.2.1.196.1.2.1.1.14	Unsigned32	read-create	Represents the idle timeout value that the WTP SHOULD enforce for its active stations.
STR capwapBaseWtpProfileWtpLocation	1.3.6.1.2.1.196.1.2.1.1.6	LongUtf8String	read-create	Represents the location of the WTP.
CAP capwapBaseWtpProfileWtpMacAddress	1.3.6.1.2.1.196.1.2.1.1.3	CapwapBaseWtpIdTC	read-create	Represents the Base MAC address of a WTP. A WTP profile MUST contain the Base MAC address of the WTP because the CAPWAP message received from the WTP contains its Base MAC address and the AC uses the Base MAC address to find the corresponding WTP profile. Section 4.6.40 of [RFC5415] omits indicating that the WTP's Base MAC address must be included in the WTP Board Data message element. This is a known errata item and should be fixed in any future revision of the RFC 5415.
U32 capwapBaseWtpProfileWtpMaxDiscoveryInterval	1.3.6.1.2.1.196.1.2.1.1.15	Unsigned32	read-create	Represents the maximum time allowed between sending Discovery Request messages, in seconds.
STR capwapBaseWtpProfileWtpModelNumber	1.3.6.1.2.1.196.1.2.1.1.4	SnmpAdminString	read-create	Represents the model number of a WTP. A WTP profile MUST include the WTP's model number, which reflects the number of Physical Layer (PHY) radios on the WTP. In this way, the creation of a WTP profile triggers the AC to automatically create the same number of WTP Virtual Radio Interfaces corresponding to the WTP's PHY radios without manual intervention. With the ifIndexes of WTP Virtual Radio Interfaces, the operator could configure and manage the WTP's PHY radios through the wireless binding MIB modules.
STR capwapBaseWtpProfileWtpName	1.3.6.1.2.1.196.1.2.1.1.5	LongUtf8String	read-create	Represents the name of the WTP.

IP capwapBaseWtpProfileWtpStaticIpAddress	1.3.6.1.2.1.196.1.2.1.1.9	InetAddress	read-create	When capwapBaseWtpProfileWtpStaticIpEnable is true, it represents the static IP address to be assigned to the WTP. The format of this IP address is determined by the corresponding instance of object capwapBaseWtpProfileWtpStaticIpType.
T/F capwapBaseWtpProfileWtpStaticIpEnable	1.3.6.1.2.1.196.1.2.1.1.7	TruthValue	read-create	Represents whether the WTP SHOULD use a static IP address or not. A value of false disables the static IP address, while a value of true enables it.
IPt capwapBaseWtpProfileWtpStaticIpType	1.3.6.1.2.1.196.1.2.1.1.8	InetAddressType	read-create	Represents the static IP address type used by the WTP. Only ipv4(1) is supported by the object. Although the CAPWAP protocol [RFC5415] supports both IPv4 and IPv6, note that the CAPWAP field modeled by this object does not support IPv6, so the object does not support ipv6(2).
U32 capwapBaseWtpProfileWtpStatisticsTimer	1.3.6.1.2.1.196.1.2.1.1.17	Unsigned32	read-create	Represents the interval the WTP uses between the WTP Event Requests it transmits to the AC to communicate its statistics, in seconds.
