Description: Manages mDNS (Bonjour) gateway configuration on Cisco LWAPP WLC for service discovery across VLANs.

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-MDNS-MIB?

CISCO-LWAPP-MDNS-MIB is a Cisco enterprise MIB that manages multicast DNS (mDNS/Bonjour) gateway functionality on Cisco Lightweight Access Point Protocol (LWAPP)-based wireless LAN controllers, allowing Bonjour service discovery to work across VLAN boundaries in enterprise wireless networks. It exposes configuration objects for globally enabling mDNS snooping and setting the query interval, along with tables for master service definitions (service name and service string) and mDNS profiles that group services and apply row-status-controlled entries. Administrators use it to monitor and control the software-level state of the mDNS gateway feature -- confirming snooping is enabled, checking the query interval, verifying which services (e.g., AirPrint, AirPlay) are defined and active via clMdnsServiceQueryStatus, and confirming profile row status -- which reveals why Bonjour-based device discovery is or isn't working across VLANs for wireless clients. It depends on the broader Cisco LWAPP/WLC wireless controller MIB family for the underlying AP and WLAN context in which the mDNS gateway operates. It is typically deployed on Cisco wireless LAN controllers in enterprise environments (e.g., education, healthcare) needing cross-VLAN Bonjour service discovery for devices like printers and Apple TVs, where CISCO-LWAPP-MDNS-MIB SNMP monitoring confirms the gateway feature is functioning correctly across the wireless network.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-LWAPP-MDNS-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 check clMdnsSnoopingEnabled and clMdnsQueryInterval to confirm mDNS gateway snooping is active and how frequently it refreshes service data, then walk clMdnsMasterServiceTable/clMdnsMasterServiceEntry to see configured clMdnsServiceName and clMdnsServiceString entries such as an AirPrint or AirPlay service definition. If a service isn't being discovered across VLANs, checking clMdnsServiceQueryStatus for that service and clMdnsProfileTable/clMdnsProfileEntry (with clMdnsProfileRowStatus) would reveal whether the service was left out of the active profile or the profile itself is not properly instantiated.

What Can Be Monitored

mDNS snooping enable status
mDNS query interval
configured mDNS services (name/string)
service query status
mDNS profile status

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoLwappMdnsMIB	1.3.6.1.4.1.9.9.842			Multicast DNS (mDNS) is a way of using familiar Domain Name System (DNS) programming interfaces, packet formats and operating, without configuring a conventional DNS server. It is useful in small networks without a DNS server, but can also work in environments beside a DNS server. mDNS functionality is provided using IP multicast over User Datagram Protocol (UDP). 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 to. Central Controller ( CC ) 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 controllers. Mobile Node ( MN ) A roaming 802.11 wireless device in a wireless network associated with an access point. Application Visibility and Control (AVC) The AVC solution is a suite of services that provides application-level classification, monitoring and traffic control.
