Cisco Catalyst 9800 Series Wireless LAN Controller (WLC) introduces a new mDNS gateway called Service-Peer mode to replace the classic mDNS flood-n-learn to support Enterprise-grade scalable, stateful, and reliable complete unicast-based mDNS service-routing with upstream gateway Cisco Catalyst 9000 Series Switches. These devices include 1 HP M452 Below, the Bonjour printer advertises the AirPrint Service and is part of default-mdns-profile. With WLC 7. Wired and wireless service providers provide service answers. 121. I will also discuss using screen mirroring and Airplay on an AppleTV v3. The WLC caches the services and providers and save it in database. One tool can perform Hence, for a Multicast DNS Mode Wireless network deployment, disable the mDNS Snooping on Cisco AireOS based WLC and enable mDNS Gateway feature on Cisco Catalyst 9800 series WLC and set the AP Multicast Mode to Multicast. 4 release WLC supports Bonjour gateway functionality on WLC itself for which you need not even enable multicast on the controller. However all the devices are being rebroadcasted over my WLAN, I want to use policies to restrict them to only certain areas. Diese Schritte werden wie folgt beschrieben: Schritt 1: Wenn Sie mDNS auf dem WLC global aktivieren WLC überwacht diese Standarddienste, wenn kein benutzerdefiniertes mDNS-Profil erstellt wurde, wie im Bild The common unified Cisco IOS-XE operating system across Cisco Catalyst 9000 series LAN switches and Cisco Catalyst 9800 series controller enables distributed Bonjour gateway function at network edge. We have Cisco WLC 5520 and APs that support flexconnect feature. Usage Guidelines The Cisco WLC snoops and learns about the mDNS service advertisements only if the service is available in the Master Services database. When You Globally Enable mDNS on the WLC WLC listens to these default services if one doesn’t have a customized mDNS profile created as shown in the image. 1X a In short I want the Airplay feature to work between user and TV subnet, we have mDNS gateway globally enabled, using default mdns service list, mDNS Flex profile created with correct VLANs and assigned to WLAN. (There are other Services you can enable in the mDNS>General menu if you’d like) Enable Global Multicast Mode Enable IGMP Snooping Enable MLD Snooping Within the WLAN Configuration: Under Advanced Tab Uncheck DHCP Addr. I have followed the Phase III Cisco guide and I've got all my AppleTV's showing up in the mDNS browser. On ISE, there's Learn how John used fully distributed mDNS processing across LAN switches and central WLC contributing to a significant boost in the system, network, and endpoint performance. 如果WLC未發現該服務，請檢查是否可在bonjour瀏覽器（Controller>>mDNS>>mDNS瀏覽器）下獲取該服務。 Bonjour瀏覽器是在WLC上看到的所有服務通告的快取，由於配置不允許學習，因此未發現該快取。 このドキュメントでは、Catalyst 9800ワイヤレスLANコントローラ(WLC)のCPU使用率を監視する方法について説明し、いくつかの設定に関する推奨事項について説明します。 このドキュメントでは、WLCによって送信されるさまざまなタイプのmDNSクエリーと、それらのクエリーが送信されるシナリオについて説明します。 Hence, for a Multicast DNS Mode Wireless network deployment, disable the mDNS Snooping on Cisco AireOS based WLC and enable mDNS Gateway feature on Cisco Catalyst 9800 series WLC and set the AP Multicast Mode to Multicast. The Bonjour protocol enables Apple devices to query and announce for specific services such as AirPlay, which ステップ 1：WLCでmDNSをグローバルに有効にする場合 カスタマイズしたmDNSプロファイルを作成していない場合、図に示すようにWLCはこれらのデフォルトサービスをリッスンします。 これらの各サービスには、サービス文 Cisco Catalyst 9800 Series Wireless LAN Controller (WLC) introduces a new mDNS gateway called Service-Peer mode to replace the classic mDNS flood-n-learn to support Enterprise-grade scalable, stateful, and reliable complete mDNS Deployment Guide for Cisco Catalyst 9800 Series Wireless Controllers, Cisco IOS XE Amsterdam 17.

Similarly, only those queries for services listed in the master-service-list are responded back I am triyng to get the mDNS Bonjour service working in WLC 8. This document describes the implementation of the Bonjour protocol on the wireless controller. The new enhanced gateway function at the first hop of wired and wireless networks communicates directly with any industry standard RFC 6762 compliant mDNS end point in Layer 2 unicast mode. 2 release, WLC supports mDNS gateway functionality for Chromecast for which the user does not need to enable multicast on the controller. Cisco Catalyst 9000 Series switches and Cisco Catalyst 9800 Series WLC introduce the unicast mode function in Local Area Bonjour network domain. 이 문서에서는 Bonjour 서비스 공급자 역할을 하도록 Chromecast 디바이스를 구성하는 방법에 대해 설명합니다. The restriction will be performed per-WLAN as well as per-user by integrating the solution I have been trying to get this to work for the longest time. Cisco Catalyst 9800 WLC can be configured as mDNS Gateway. Wireless has become the preferred option for users to access the network, and in many cases the only practical one. This feature is called mDNS Gateway. I have also tried with global multicast enabled - still no Mobility has rapidly changed the expectation of wireless network resources and the way users perceive it. Apple AirPrint and AirPlay services will be used in our In order to address this issue, the Cisco Wireless LAN Controller (WLC) acts as a Bonjour Gateway. The WLC The WLC snoops and learns about mDNS service advertisements only if the service is present in the master-service-list database. For example, Apple TV and responds back to Bonjour clients when they ask/request for a service. 4) for the Wireless LAN Controller (WLC).
