If your network is live, ensure that you understand the potential impact of any command. Bonjour protocol is an Apple service discovery protocol which locates devices and sevices on a local network with the use of multicast Domain Name System mDNS service records.
The Bonjour protocol operates on service announcements and service queries. Each query or advertisement is sent to the Bonjour multicast address ipv4 The address used by the Bonjour protocol is link-local multicast address and therefore is only forwarded to the local L2 network. Routers cannot use multicast routing to redirect the traffic because the time to live TTL is set to 1. This lead to scability problems.
This way you can have the sources and clients in different subnets. These steps are described as follows:. WLC listens to these default services if one doesn't have a customized mDNS profile created as shown in the image.
Each of these services has a service string associated with it. Service strings are used to match service instances to service queries. A service type always contains the service name and the protocol. Additionally, it may contain one or more subtype identifiers. Packet 83 shows that WLC sends a query over the wireless. The inner packet shows WLC querying to Since this query is over the wireless, capwap header is added to the packet with outer source IP still to be that of management but the destination is multicast IP Now, where does this multicast IP The APs join this multicast group and listen on it.
WLC forwards the query to this group, APs receive it and send it over the air. The address As the devices are in different vlans, one needs to have multicast routing enabled for vlan 1 and on the wired for this to work.
Note : If multicast routing is not enabled on the wired for wlc and AP management vlan, then AP multicast mode must be set to unicast. In this mode, the controller unicasts every multicast packet to every AP associated to the controller. This mode is very inefficient and is not recommended. The debugs reflect the same thing as seen in the captures.
Here the snippet only shows query from management interface. In this packet, the Apple TV Since in this case Apple TV is wireless , one can see the advertisement being sent over capwap. In this scenario, Apple TV responded with 21 services out of which only Airplay service is of interest. Later on, at any point in time, the wireless client The source IP of the inner packet is the dynamic interface of the client vlan, in this case This section provides information you can use in order to confirm and troubleshoot your configuration.
In order to identify and isolate issues in mdns requires the configuration to be correct and thus requires few basic checks. Step 2. If you use a custom mDNS profile ensure that all the required services are added to it. Step 3. Step 4. Check if the Click MGID.
The Multicast Group Detail page appears. Check the Multicast Status details. Configure the multicast-direct feature on WLANs media stream by entering this command:. The Resource Reservation Control RRC parameters are assigned with the predefined values based on the values assigned to the template.
The following templates are used to assign RRC parameters to the media stream:. Enable a specific enhanced distributed channel access EDC profile by entering this command:. Enable the admission control on the desired bandwidth by entering the following commands:. Enable bandwidth-based voice CAC for Set the percentage of the maximum bandwidth allocated to clients for voice applications on the Configure the percentage of the maximum allocated bandwidth reserved for roaming voice clients on the Set the maximum limit to the number multicast streams per radio by entering this command:.
Set the maximum number of multicast streams per client by entering this command:. Choose Wireless and then Network under The Choose the Media tab to open the Media page. Once the client reaches the specified value, the access point rejects new calls on this radio band. In the Client Phy Rate text box, enter the value for the rate in kilobits per second at which the client operates.
From the Max Streams per Radio drop-down list, choose the maximum number of allowed multicast direct streams per radio. Choose a value between 1 to 20 or No Limit. The default value is set to No Limit. From the Max Streams per Client drop-down list, choose the maximum number of allowed clients per radio.
If you want to enable the best radio queue for this radio, select the Best Effort QoS Admission check box. See a summary of the media stream and client information by entering this command:. See details of the All the valid mDNS service advertisements that are received by the controller are tagged with the MAC address of the AP that is associated with the service advertisement from the service provider while inserting the new entry into the service provider database.
If LSS is disabled for any service, the wireless service provider database entries are not filtered when they respond to any query from a wireless client for the service. LSS applies only to wireless service provider database entries. There is no location awareness for wired service provider devices. APs can be in either the access port or the trunk port to learn the mDNS packets from the wired side and forward them to the controller.
You can use the configurable knob that is provided on the controller to start or stop mDNS packet forwarding from a specific AP. The AP sends untagged packets when a query is to be sent. There is no check to ensure that no two mDNS APs are duplicating the same traffic for the same service. But, for the same VLAN, there is such a check. If an mDNS AP is reset or associated with the same controller or another controller, one of the following occurs:.
If the global snooping is disabled on the controller, a payload is sent to the AP to disable mDNS snooping. If the global snooping is enabled on the controller, the configuration of the AP before the reset or the association procedure is retained. This guarantees that any service advertisements originating from these MAC addresses for the configured services are learned even if the service provider database is full by deleting the last nonpriority service provider from the service that has the highest number of service providers.
When you configure the priority MAC address for a service, there is an optional parameter called ap-group, which is applicable only to wired service providers to associate a sense of location to the wired service provider devices. When a client mDNS query originates from this ap-group, the wired entries with priority MAC and ap-group are looked up and the wired entries are listed first in the aggregated response.
You can configure a service to filter inbound traffic that is based on its origin, that is either wired or wireless. When the learn origin is wired, the LSS cannot be enabled for the service because LSS applies only to wireless services. A service that has its origin set to wireless cannot be changed to wired if the LSS status is enabled for the service because LSS is applicable only to wireless service provider database. If you change the origin between wired and wireless, the service provider database entries with the prior origin type is cleared.
Devices that are advertised by the third-party servers or applications are not populated on the mDNS service or device table correctly on the controller. This is in order to prevent Bonjour multicast traffic from overwhelming the network. Enter the mDNS query interval in minutes. The query interval is the frequency at which the controller queries for a service. Choose a service from the Select Service drop-down list. To add a new mDNS-supported service to the list, choose Other.
Specify the service name and the service string. The controller snoops and learns about the mDNS service advertisements only if the service is available in the Master Services Database. The controller can snoop and learn a maximum of 64 services. Select or unselect the Query Status check box to enable or disable an mDNS query for a service, respectively. To view the details of an mDNS service, hover your cursor over the blue drop-down arrow of a service, and choose Details.
The controller has a default mDNS profile, which is default-mdns-profile. It is not possible to delete the default profile. To create a new profile, click New , enter a profile name, and click Apply. To edit a profile, click a profile name on the mDNS Profiles page; from the Service Name drop-down list, choose a service to be associated with the profile, and click Apply.
After creating a new profile, you must map the profile to an interface group, an interface, or a WLAN. Clients receive service advertisements only for the services associated with the profile. The highest priority is given to the profiles associated with interface groups, followed by the interface profiles, and then the WLAN profiles. Each client is mapped to a profile based on the order of priority.
From the mDNS Profile drop-down list, choose a profile. Choose WLANs. If you try to delete an mDNS profile that is already associated with an interface group, an interface, or a WLAN, an error message is displayed. If the mDNS profile name is none , no profiles are attached to the interface group. Any existing profile that is attached is removed. View information about an mDNS profile that is associated with an interface group by entering this command:. View information about the mDNS profile that is associated with an interface by entering this command:.
View information about the mDNS domain names that are learned by entering this command:. Summary— show mdns service summary. Detailed— show mdns service detailed service-name. It is not possible to configure wired services if LSS is enabled and vice versa.
It is not possible to enable LSS for wired-only service learn origin. Service advertisements across all VLANs and origin types that are not learned are displayed. The optional AP group is applicable only to wired service provider devices to give them a sense of location; these service providers are placed higher in the order than the other wired devices. From 7. To address this issue controller acts as a Bonjour Gateway.
Bonjour gateway has inadequate capabilities to filter cached wired or wireless service instances based on the credentials of the querying client and its location. Location-Specific Services LSS filters the wireless service instances only while responding to a query from wireless clients.
The filtering is based on the radio neighborhood of the querying client. LSS filtering is per service type and not per client. It means that all clients receive the location based filtered response if LSS is enabled for the service type and clients cannot override the behavior. The configuration can be applied to wired and wireless service instances. The response to any query is on the policy configured for each service instance.
The response enables the selective sharing of service instances based on the location, user-id or role. As the most service publishing devices are wired, the configuration allows filtering of wired services at par with the wireless service instances. The total number of policies that can be created is same as the number of service instances that are supported on the platform. Hundred policies can be supported; 99 policies and one default policy.
Policy and rules can be created irrespective of the service instances. The policy is applied only when it is complete and discovers the target service instances. Enter the name of service provider in Name. Click Add. From the Location Type drop-down list, choose the type of location. If the location is selected as 'Any', the policy checks on the location attribute are not performed. The policy is applied on the first substring match.
The list of current service instances associated with the service group is shown in a table. Enable or disable the mDNS policy by entering this command: config mdns policy enable disable.

PDF - Complete Book Updated: March 28, The controller can perform multicasting in one of two modes: Unicast mode: In this mode, the controller unicasts every multicast packet to every access point associated to the controller.
Note We recommend that you use the unicast method only in networks where 50 or fewer APs are joined with the controller. Note If Layer 2 multicast is enabled, a single MGID is assigned to all the multicast addresses coming from an interface. Depending on your requirements, you can take the following actions: If you need to transmit multicast data with the greatest reliability and if there is no need for great multicast bandwidth, then configure a single basic rate, that is low enough to reach the edges of the wireless cells.
Configure Media Stream. The parameters that affect Multicast forwarding are: Controller platform. Global AP multicast mode configuration at controller. Table 1. Step 9 Click Apply. Step 10 Click Save Configuration. Step 4 Set the IGMP timeout value by entering this command: config network multicast igmp timeout timeout You can enter a timeout value between 30 and seconds. Note To enable MLD snooping, you must enable global multicast mode of the controller.
Step 8 Set the MLD query interval by entering this command: config network multicast mld query interval interval Enter the MLD query interval value in seconds. Information similar to the following appears: Mgid Verify that the access points have joined the controllers. Note Enabling the multicast direct feature does not automatically reset the existing client state.
Note We recommend that you use a template to add a media stream to the controller. From the Select from Predefined Templates drop-down list under Resource Reservation Control RRC Parameters, choose one of the following options to specify the details about the resource reservation control: Very Coarse below kbps Coarse below kbps Ordinary below kbps Low below 1 Mbps Medium below 3 Mbps High below 5 Mbps Note When you select a predefined template from the drop-down list, the following text boxes under the Resource Reservation Control RRC Parameters list their default values that are assigned with the template.
The possible values are as follows: Drop—Specifies that a stream is dropped on periodic revaluation. Step 5 Enable the admission control on a band for video optional by following these steps: Note Keep the voice bandwidth allocation to a minimum for better performance. Step 6 Configure the video bandwidth by following these steps: Note The template bandwidth that is configured for a media stream should be more than the bandwidth for the source media stream. Note The voice configuration is optional.
Step 9 Enable the The Clients page appears. Step 3 Choose Wireless and then Network under Step 5 Choose the Media tab to open the Media page. Step 8 In the Client Phy Rate text box, enter the value for the rate in kilobits per second at which the client operates. Step 11 From the Max Streams per Radio drop-down list, choose the maximum number of allowed multicast direct streams per radio.
Step 12 From the Max Streams per Client drop-down list, choose the maximum number of allowed clients per radio. If an mDNS AP is reset or associated with the same controller or another controller, one of the following occurs: If the global snooping is disabled on the controller, a payload is sent to the AP to disable mDNS snooping. Forwards the query as Origin-Based Service Discovery You can configure a service to filter inbound traffic that is based on its origin, that is either wired or wireless.
LSS filtering is restricted to only wireless services. You can add multiple services to a profile. Step 3 Click Save Configuration. What to do next After creating a new profile, you must map the profile to an interface group, an interface, or a WLAN. Click the corresponding interface group name. Click the corresponding interface name. Click the Advanced tab. Select the mDNS Snooping check box. View the status of origin-based service discovery by entering this command: Summary— show mdns service summary Detailed— show mdns service detailed service-name View all the service advertisements that are present in the controller, but not discovered because of restrictions on learning those services, by entering this command: show mdns service not-learnt Service advertisements across all VLANs and origin types that are not learned are displayed.
Currently the limitations are: Location-Specific Services LSS filters the wireless service instances only while responding to a query from wireless clients. LSS cannot filter wired service instance because of no sense of location. There is no other filtering mechanism based on client role or user-id. The requirement is to have configuration per service instance. Following are the three criteria of the service instance sharing: User-id Client-role Client location The configuration can be applied to wired and wireless service instances.
There are two levels of filtering client queries: At the service type level by using the mDNS profile At the service instance level using the access policy associated with the service. The number of rules per policy is limited to one. A service instance can be associated with a maximum of five policies.
Five service groups can be assigned for a MAC address. Step 2 Select service group from the list of Group Names. Note If the location is selected as 'Any', the policy checks on the location attribute are not performed. Note The list of current service instances associated with the service group is shown in a table. Was this Document Helpful? Yes No Feedback.

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect the strap to one of the following:. Follow the installation prompts to install the driver. Step 3 Configure the terminal emulation program for the following parameters:.
When you plug the controller into an AC power source, the bootup script initializes the system, verifies the hardware configuration, loads its microcode into memory, verifies its operating system software load, and initializes itself with its stored configurations. Follow these steps to run the bootup script and conduct the power-on self test POST. Step 2 Turn on the power supply. Step 3 Observe the bootup on the CLI screen. The bootup script displays operating system software initialization code download and POST verification and basic configuration as shown in the following sample bootup display:.
Note Enter 1 to run the current software, enter 2 to run the previous software, or enter 4 to run the current software and set the controller configuration to factory defaults. Do not choose the other options unless directed to do so. Only options 1 through 3 are available in FIPS mode. Step 5 The rest of the process takes two to three minutes.
Do not reboot the controller until the user login prompt appears. Step 6 If the controller passes the power-on self test, the bootup script runs the Startup Wizard, which prompts you for basic configuration input. Note The available options appear in brackets after each configuration parameter. The default value appears in all uppercase letters. Note Press the hyphen key if you need to return to the previous command line.
To configure the controller for basic operation using the Startup Wizard, follow these steps:. Step 1 When prompted to terminate the AutoInstall process, enter yes. If you do not enter yes , the AutoInstall process begins after 30 seconds. Note The AutoInstall feature downloads a configuration file from a TFTP server and then loads the configuration onto the controller automatically.
Step 2 Enter the system name, which is the name you want to assign to the controller. Step 3 Enter the administrative username and password to be assigned to this controller. The default administrative username and password are admin and admin , respectively.
If you do not want to use the service port or if you want to assign a static IP address to the service-port interface, enter none. Note The service-port interface controls communications through the service port. Its IP address must be on a different subnet from the management interface. This configuration enables you to manage the controller directly or through a dedicated management network to ensure service access during network downtime.
The service port works with auto-negotiation and in full duplex mode only. The other device such as switch and access point that communicates with the controller must be set to full duplex and auto-negotiation mode. You can use the command show interface detailed service-port to check all the service port interface parameters on the controller.
Step 5 If you entered none in Step 4 , enter the IP address and netmask for the service-port interface on the next two lines. Step 6 Enable or disable link aggregation LAG by choosing yes or no. Note The management interface is the default interface for in-band management of the controller and connectivity to enterprise services such as AAA servers.
