Description: MIB for Proxy Mobile IPv6 (PMIP) local mobility anchor configuration and session status on Cisco LWAPP wireless LAN controllers

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-LWAPP-PMIP-MIB?

The CISCO-LWAPP-PMIP-MIB manages Proxy Mobile IPv6 configuration and status for the local mobility anchor relationship on Cisco Wireless LAN Controllers acting as Mobile Access Gateways that terminate LWAPP tunnels from lightweight access points. It exposes objects for PMIP domain naming, MAG interface assignment, binding lifetime/refresh/retransmission timers, and access point name configuration used in mobility signaling. Administrators use it to monitor the software-level health of the mobility binding relationship, tracking binding lifetime and refresh timers to ensure the WLC's binding with the Local Mobility Anchor doesn't expire unexpectedly, which would disrupt client mobility and session continuity across access points. It explicitly depends on the IETF Proxy Mobile IPv6 standard defined in RFC 5213 for its protocol semantics. It is deployed in mobile/enterprise wireless networks using PMIPv6-based mobility architectures where Cisco WLCs act as Mobile Access Gateways communicating with a Local Mobility Anchor. Engineers can download the CISCO-LWAPP-PMIP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-LWAPP-PMIP-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

Cisco Wireless LAN Controller (WLC) acting as a PMIPv6 Mobile Access Gateway

Monitoring Examples

cLPmipDomainName and cLPmipMAGInterface identify which mobility domain and interface the WLC's PMIP MAG role is bound to, while cLPmipBindingLifeTime and cLPmipBindingRefreshTime govern how long a client's mobility binding remains valid before requiring renewal. An admin watching cLPmipBindingInitRetxTime/cLPmipBindingMaxRetxTime alongside actual binding renewal success can detect if bindings are repeatedly retransmitting and potentially failing, which would signal LMA reachability problems affecting client mobility.

What Can Be Monitored

PMIP binding lifetime and refresh timing
binding retransmission timers
mobility domain and MAG interface configuration
APN configuration

How to Use in IPNetwork Monitor

Example using cLPmipLmaTotalBindings OID:

Select a Cisco Wireless LAN Controller acting as a PMIPv6 Mobile Access Gateway 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 cLPmipLmaTotalBindings 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. This object represents total number of bindings sent to the LMA by the controller. 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 (in packets), 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
ciscoLwappPmipMIB	1.3.6.1.4.1.9.9.845			This MIB is intended to be implemented on all those devices operating as Wireless LAN Controllers (WLC) that terminate the Light Weight Access Point Protocol tunnel from light weight LWAPP Access Points. This MIB provides configuration and status information about local mobility anchor to which the controller has joined. The relationship between CC and the LWAPP APs can be depicted as follows: +......+ +......+ +......+ +......+ + + + + + + + + + LMA + + LMA + + LMA + + LMA + + + + + + + + + +......+ +......+ +......+ +......+ .. . . . .. . . . . . . . . . . . . . . . . . . . . . . . +......+ +......+ +......+ +......+ +......+ + + + + + + + + + + + WLC + + WLC + + WLC + + WLC + + WLC + + + + + + + + + + + +......+ +......+ +......+ +......+ +......+ . . . . . . . . . . . . . . . . . . . . . . . . +......+ +......+ +......+ +......+ +......+ + + + + + + + + + + + AP + + AP + + AP + + AP + + AP + + + + + + + + + + + +......+ +......+ +......+ +......+ +......+ . . . . . . . . . . . . . . . . . . . . . . . . +......+ +......+ +......+ +......+ +......+ + + + + + + + + + + + MN + + MN + + MN + + MN + + MN + + + + + + + + + + + +......+ +......+ +......+ +......+ +......+ The LWAPP tunnel exists between the controller and the APs. The MNs communicate with the APs through the protocol defined by the 802.11 standard. LWAPP APs, upon bootup, discover and join one of the controllers and the controller pushes the configuration, that includes the WLAN parameters, to the LWAPP APs. The APs then encapsulate all the 802.11 frames from wireless clients inside LWAPP frames and forward the LWAPP frames to the controller. GLOSSARY Access Point ( AP ) An entity that contains an 802.11 medium access control (MAC) and physical layer ( PHY ) interface and provides access to the distribution services via the wireless medium for associated clients. LWAPP APs encapsulate all the 802.11 frames in LWAPP frames and sends it to the controller to which it is logically connected. Wireless LAN Controller ( WLC ) The central entity that terminates the LWAPP protocol tunnel from the LWAPP APs. Throughout this MIB, this entity also referred to as 'controller'. Light Weight Access Point Protocol ( LWAPP ) This is a generic protocol that defines the communication between the Access Points and the Central Controller. Mobile Node ( MN ) A roaming 802.11 wireless device in a wireless network associated with an access point. Proxy Mobile IP (PMIP) PMIP is a protocol intended for providing network-based IP mobility management support to a mobile node, without requiring the participation of the mobile node in any IP mobility related signaling. The mobility entities in the network will track the mobile node's movements and will initiate the mobility signaling and set up the required routing state. Local Mobility Anchor (LMA) Local Mobility Anchor is the home agent for the mobile node in a Proxy Mobile domain. It is the topological anchor point for the mobile node's home network prefix(es) and is the entity that manages the mobile node's binding state. Network Access Identifier(NAI) The Network Access Identifier (NAI) is the user identity submitted by the client during network access authentication. In roaming, the purpose of the NAI is to identify the user as well as to assist in the routing of the authentication request. Binding Revocation Indication(BRI) Binding Revocation Indication(BRI) is a message sent by either the LMA or the controller to revoke the bindings present. LMA can send a revocation for specific NAI or NAIs belonging to the controller. Binding Revocation Acknowledgement(BRA) When the BRI is received, the responder must send a Binding Revocation Acknowledgement message to indicate the receipt and the status of processing of the corresponding BRI message. Mobile Access Gateway(MAG) Mobile Access Gateway (MAG) performs mobility-related signaling on behalf of the mobile nodes (MN) attached to its access links.
