Configuring NTP on Cisco Vision Dynamic Signage Director Servers and DMPs
Network Time Protocol (NTP) service is required in Cisco Vision Dynamic Signage Director on the following devices:
Cisco Vision Dynamic Signage Director servers
Cisco Vision Dynamic Signage Director Remote servers
Cisco DMP 4310Gs
SV-4K and DMP-2K Precision Time Protocol (PTP) master device
NTP provides reliable clocking for your Cisco Vision network. NTP helps ensure synchronicity between redundant servers and the Cisco
Vision Dynamic Signage Director remote servers, and optimizes playlist synchronization on the Cisco DMP 4310Gs.
Note:
For optimized synchronization on the SV-4K and DMP-2K media players, PTP is used. Only the PTP masters derive a clock using
NTP.
You should verify the NTP configuration for your Cisco Vision Dynamic Signage Director servers, since the default NTP source is a Red
Hat Linux public pool and might not be the NTP server source that you want to use for your venue.
Configuration of the DMP NTP source is done within the Cisco Vision Dynamic Signage Director Management Dashboard. As a best practice, the Cisco Vision Dynamic Signage Director server is already set as the NTP host by default for all media players. This does not need to be changed unless the venue requires a different NTP source.
Caution: The Cisco Vision Dynamic Signage Director server is itself enabled as an NTP host to provide timing to the media players only. You also can use the Cisco Vision Dynamic Signage Director server as the NTP host for your remote servers. Do not use Cisco
Vision Dynamic Signage Director as an NTP host for other devices in your network.
This section includes the following tasks:
(required)
Configuring NTP on the Cisco DMP 4310G, page 22
(required)
Configuring NTP and PTP on the SV-4K and DMP-2K Media Players, page 29
(required)
Prerequisites for Configuring NTP on Cisco Vision Dynamic Signage Director Servers and DMPs
Caution: If you are running Cisco Vision Dynamic Signage Director on a virtual server, then you should reference a reliable NTP server running on a bare metal server, rather than relying on a clock from a VM environment that can drift and is not accurate.
Before configuring NTP on Cisco Vision Dynamic Signage Director servers and DMPs, be sure that the following requirements are met:
You understand how to use vi editor commands.
You understand the NTP host requirements for your Cisco Vision Dynamic Signage Director servers:
—
If you do not want to use the default public pool of NTP servers for the Cisco Vision Dynamic Signage Director servers, you have the IP address or DNS name of the NTP host for your network.
—
If you plan to use a public pool of NTP servers, be sure that the servers are reachable from the Cisco Vision Dynamic Signage
Director network. By default, the ntp.conf file on Cisco Vision Dynamic Signage Director servers has configured the following
Red Hat Linux public pool of servers: server 0.rhel.pool.ntp.org
server 1.rhel.pool.ntp.org
server 2.rhel.pool.ntp.org
17
Configuring the Cisco Vision Dynamic Signage Director Server System Settings
How to Configure Cisco Vision Dynamic Signage Director Server System Settings
Tip:
For more information about using NTP pool servers see the Network Time Protocol website.
If you plan to change the default best practice of using the Cisco Vision Dynamic Signage Director server as the NTP source for DMPs, be sure that the following requirements are met:
—
You have configured the NTP host for the Cisco Vision Dynamic Signage Director server first.
—
You have upgraded the DMP firmware.
For more information about how to upgrade the DMP firmware, see the Cisco Vision Software Installation and Upgrade Guide:
Dynamic Signage Director for your release.
—
For optimal synchronization, use the same NTP server that is configured for the Cisco Vision Dynamic Signage Director server.
However, it is not required.
—
The DMP must not reference an NTP server pool. If the Cisco Vision Dynamic Signage Director server references an NTP server pool (the default), then select a specific server from that same pool as the NTP server for the DMPs.
—
Only IPv4 is supported for the NTP server address on the DMPs.
—
The NTP server for the DMPs must not be a load-balanced server.
The Cisco Vision Dynamic Signage Director network is configured to allow bidirectional transmission of UDP messages on port 123 for NTP messages.
UDP port 123 is used for communication between the Cisco Vision Dynamic Signage Director servers and NTP hosts, and the DMPs and NTP host (by default, this is the Cisco Vision Dynamic Signage Director server).
For a complete port reference for Cisco Vision Dynamic Signage Director servers, see the “Port Reference” module of the Cisco Vision
Software Installation and Upgrade Guide: Dynamic Signage Director for your release.
Configuring the System Date and Time Using NTP on Cisco Vision Dynamic Signage Director Servers
When you install or upgrade the Cisco Vision Dynamic Signage Director or Cisco Vision Dynamic Signage Director Remote servers, you need to configure the system date and time in the TUI. You also need to configure the time zone.
Note:
Although you can manually configure the system date and time on your servers when necessary, this should be avoided for your production network.

(if necessary)
Setting Up the NTP Source on Cisco Vision Dynamic Signage Director Servers
Note:
Complete this task only if you do not want to use the default public pool of servers.
Standard NTP server configuration uses the word “server” followed by the Domain Name System (DNS) name or IP address of an NTP server. By default, the ntp.conf file on Cisco Vision Dynamic Signage Director servers has configured the following Red Hat Linux public pool of servers: server 0.rhel.pool.ntp.org
server 1.rhel.pool.ntp.org
server 2.rhel.pool.ntp.org
For these servers to be used as a reference clock, they must be reachable from the Cisco Vision Dynamic Signage Director network.

How to Configure Cisco Vision Dynamic Signage Director Server System Settings
If you want to use your own server, be sure to add it and comment out these default pool servers in the ntp.conf file. Otherwise, you do not need to do any further editing of the ntp.conf file in this task.
To set up the NTP host on Cisco Vision Dynamic Signage Director servers, complete the following steps:
1.
From the TUI Main Menu, go to System Settings > Date and Time Settings > Setup NTP Source.
A confirmation screen to Configure NTP and edit the ntp.conf file is displayed.
2.
To open the ntp.conf file for edit, press any key.
The ntp.conf file opens in the vi editor and the cursor is positioned at the end of the last configured NTP server line. If this is not the case, navigate to the server configuration section.
3.
To enter INSERT line editing mode, type i.
The vi editor changes to INSERT mode.
4.
If you have a server that you want to use as the reference clock source at your site, do the following:
—
Add a line and type “server ip-address” or “server dns-name,” where ip-address or dns-name is replaced by the IP address or name of the NTP server that you want to configure.
—
Go to the lines where the pool servers are configured and add a “#” sign in front to comment them out of the configuration as shown below:
#server 0.rhel.pool.ntp.org
#server 1.rhel.pool.ntp.org
#server 2.rhel.pool.ntp.org
5.
To exit INSERT mode and return to vi command mode, press Esc.

Go to the Management Dashboard and do the following:
—
In the NTP status property, type the value to “Synchronized to server svd-ip at stratum n” and be sure that the IP address is set to your NTP host and the stratum level matches the level that you confirmed in Step 1 .
—
Run the Global DMP settings command to apply the configuration to all DMPs.

Configuring NTP and PTP on the SV-4K and DMP-2K Media Players
By default, both NTP and PTP services are automatically enabled for SV-4K and DMP-2K media players. The SV-4K and DMP-2K media players use PTP to achieve optimal synchronization. However, an NTP source also must be used to provide initial clocking to the devices that are elected PTP masters in the network.
This section provides information about the default settings and how to modify them. It includes the following tasks:
Restrictions for NTP and PTP on the SV-4K and DMP-2K Media Players, page 29
Guidelines for NTP and PTP on the SV-4K and DMP-2K Media Players, page 30
Verifying PTP Operation for the SV-4K and DMP-2K Media Player, page 33
Restrictions for NTP and PTP on the SV-4K and DMP-2K Media Players
Before you configure PTP on the SV-4K and DMP-2K media players, consider the following restrictions:
By default, PTP messages will not cross VLANs and PTP master candidates need to be identified for each VLAN and configured in the Management Dashboard.
However, Release 4.1 and later supports a configurable Precision Time Protocol (PTP) Time To Live (TTL) setting in the Management
Dashboard. The PTP TTL specifies the number of VLANs that can be crossed for selection of a PTP master. The default value of 1
(recommended) means that each VLAN will elect its own PTP master.
Note:
For ease of configuration for venues with multiple VLANs, the system is configured by default to list all SV-4K and DMP-2K devices as eligible PTP master candidates. However, be aware that although this simplifies configuration, the time that it takes for the
SV-4K and DMP-2Ks to arbitrate a master device in each network will vary, and depends on the number of eligible devices in each network.

How to Configure Cisco Vision Dynamic Signage Director Server System Settings
Content synchronization for video playback on the SV-4K and DMP-2K media player relies on precise time across DMPs using PTP.
The behavior is similar to content synchronization on the Cisco DMP 4310G. If SV-4K and DMP-2K devices are playing video and one of the devices reboots, the rebooting unit will restart video playback from the beginning and will only synchronize with the other players when the next item in the playlist is rendered.
If SV-4K and DMP-2Ks are participating in zone-based content synchronization for video walls, with some enhanced synchronization capability, the rebooting unit will synchronize with the current item being played by the device leader in the video wall. For more information, see the “Working with Video Walls” section of the Cisco Vision Operations Guide: Dynamic Signage Director Release
5.0.
Guidelines for NTP and PTP on the SV-4K and DMP-2K Media Players
Before you configure NTP and PTP on the SV-4K and DMP-2K media players, consider the following guidelines:
For new installations of Cisco Vision Dynamic Signage Director, PTP is the default time source for the SV-4K and DMP-2K media players, with NTP as the default time source for the elected PTP master.
NTP Guidelines
Each SV-4K and DMP-2K media player designated as PTP master (per VLAN) will use NTP as its time source. The other devices in the network operate using a PTP reference clock from the elected PTP master.
When PTP is disabled (not recommended), all SV-4K and DMP-2K devices use NTP to set their local clock.
Note:
For synchronized video playback, NTP alone cannot be relied upon for SV-4K and DMP-2K devices and PTP must be used.
The default NTP synchronization interval with the host time server is one hour and is configurable.
An NTP source must be configured in Cisco Vision Dynamic Signage Director. By default, the Cisco Vision Dynamic Signage Director server is configured as the SV-4K and DMP-2K NTP host (just as with the Cisco DMP 4310G).
PTP Guidelines
PTP version 2 is supported only for the SV-4K and DMP-2K media players and applies globally to all devices in the Cisco Vision
Dynamic Signage Director network when configured.
PTP configuration includes a PTP domain and a set of master candidates:
—
PTP domain—Default is 0.
Be sure that this domain does not conflict with any other PTP domain (and multicast addressing) in use in your network, and revise as needed. See Table 3 for more information.
—
PTP master candidates—Default is *.
This specifies that all SV-4K and DMP-2K devices in the network are eligible as master candidates and will go through arbitration to designate a master for their respective subnets.
If you revise the default PTP master candidates configuration, you must configure one or more SV-4K and DMP-2K devices as master candidates in a semicolon-separated list of IP addresses for each VLAN.
A minimum of two master candidates per network is recommended.
If there is an in-house PTP master for your network, leave the “PTP master candidates” property value blank. However, this configuration is only supported for venues without multiple subnets.

HDMI-In Encoding on the SV-4K Media Player to Stream Video as a Channel
In Release 4.1 and later releases, Cisco Vision Dynamic Signage Director supports streaming video from a laptop or other supported device connected to the HDMI-In port on an SV-4K media player to be played as a multicast-based channel in Cisco Vision Dynamic Signage
Director.
The allowable multicast range to use for this feature in the Connected Venue (Connected Stadium) network is 239.193.20.0/24.
Note:
If you want to maintain privacy of channels, create a DMP-encoded channel per suite with a unique multicast address (from
239.193.20.0/24 range), and create a separate channel guide per suite. For example, if you have 10 suites—create 10 separate DMP-encoded channels with unique multicast addresses, create 10 different channel guides for each DMP-encoded channel, and assign each suite to a different channel guide.
For more information about configuring this feature, see the Cisco StadiumVision Director Operations Guide .
Per-Script Multicast Optimization
In Cisco StadiumVision Director Release 3.2 and later releases, the original Multicast Optimization introduced in Release 3.1 is replaced by Per-Script Multicast Optimization (for up to 20 different scripts) to reduce the number of multicast messages that each DMP must process.
Per-Script Multicast Optimization is designed to reduce the load on DMPs when the following conditions are present in Cisco
StadiumVision Director:
More than one event script is run simultaneously in a venue.
The scripts can be running across multiple venues, scripts running in a single venue, or running in systems without Cisco Vision
Dynamic Signage Director Remote servers.
The External Content Integration feature is used, which sends multiple messages to the DMPs in a script.
Table 5 provides a summary of the two different multicast optimization features supported in Cisco Vision Dynamic Signage Director.

.
2.
If you are running more than 20 scripts, then the first 20 scripts operate using per-script multicast channels, and the additional scripts are run over the global multicast host port.
Benefits of Per-Script Multicast
In releases of Cisco StadiumVision Director 3.1 and earlier, the server uses a single multicast channel for all DMPs. In Release 3.2 and later, you can configure multiple multicast channels, over which the server sends only the multicast messages needed for a particular event script for up to 20 scripts.
If you are running more than 20 scripts, then the first 20 scripts operate using per-script multicast channels, and the additional scripts are run over the global multicast host port.

Configuring the Cisco Vision Dynamic Signage Director Server System Settings
How to Configure Cisco Vision Dynamic Signage Director Server System Settings
Figure 15 shows this message separation. Each DMP goes from seeing four packets to seeing two. More importantly, each DMP now only has to process one XML payload, which is important when the XML payloads are sizeable.
Figure 15 Multicast Messaging With and Without Per-Script Multicast Optimization
All DMPs, including those associated with a Cisco Vision Dynamic Signage Director Remote server, listen on these per-script multicast channels.
For messages that apply to multiple event scripts, the message is duplicated and sent to each multicast channel. Therefore, this feature can increase the load on Cisco Vision Dynamic Signage Director and Cisco Vision Dynamic Signage Director Remote servers (increasing the number of messages sent and copying of messages) as a tradeoff for reducing the number of messages seen and processed by DMPs.
However, this load is expected to be negligible.
Multicast Registry Keys in Cisco Vision Dynamic Signage Director
Cisco Vision Dynamic Signage Director uses multicast messages for DMP control-plane operation. Cisco Connected Venue (Connected
Stadium) network design assigns the following multicast group addresses for use by Cisco Vision Dynamic Signage Director:
239.193.0.0/24—For control communication
239.192.0.0/24—For video communication (This network should be avoided for the multicast configuration described in this module.)
Multicast addressing is configured using registry keys from the Cisco Vision Dynamic Signage Director Management Dashboard.
Table 6 describes the registry keys in Cisco Vision Dynamic Signage Director that control the multicast configuration.
Note:
The default PTP domain 0 uses multicast address 224.0.1.129. For more information, see

239.193.0.254:50080–239.193.0.254:5
0099 is used as the range of Global hostports for the running scripts.
These ports are used with the network specified in the MulticastHostPort registry key, to define a range of additional global hostports to be assigned for running scripts.
Prerequisites for Configuring Multicast Ports in Cisco Vision Dynamic Signage Director
Before you configure multicast ports, be sure that the following requirements are met:
Be sure that you understand the multicast addressing in use for all areas of your Cisco Vision Dynamic Signage Director network, including Cisco Connected Venue and Cisco Vision Mobile networks. Confirm that there are not any multicast address/port overlaps.
Caution:
Because of the large number of ports that per-script multicast configuration requires, and the possibility for
hard-to-diagnose failures if video is routed to a DMP's control channel (which can occur when the port numbers are the same and even if the group/host portion is different), it is critical to verify that the port ranges you plan to use are not used by any other source of multicast in the network.

How to Configure Multicast Ports in Cisco Vision Dynamic Signage Director
This section includes the following tasks:
Configuring Per-Script Multicast in Cisco Vision Dynamic Signage Director, page 38 (recommended)
Configuring the Global Multicast Host Port in Cisco Vision Dynamic Signage Director
The global multicast host port is used by Cisco Vision Dynamic Signage Director to send messages to DMPs when they are not part of a script, when per-script multicast is disabled, or when the number of scripts running exceeds to configured maximum of per-script multicast ports.
It is configured in the “MulticastHostPort” registry key in the Management Dashboard.
Note:
The default value currently uses the address 239.192.0.254:50001 and should be changed to a network address in the range
239.193.0.0/24.
To verify or configure the multicast addressing for Cisco Vision Dynamic Signage Director, complete the following steps:
1.
From the Management Dashboard, select Tools > Advanced > Registry.
2.
Scroll to the “MulticastHostPort” registry key in the Parameters list and confirm the entry for the registry.
3.
Click on the value field and specify a multicast address in the range 239.193.0.0/24 and port number.
Note:

Troubleshooting Per-Script Multicast Configuration
This section includes information about troubleshooting the following behaviors when per-script multicast optimization is enabled:
Scripts Unable to Start or Stop, page 39
Scripts Unable to Start or Stop
Verify that the multicast packets are reaching the DMPs using any or all of the following methods:
Look at the sv_msg_mcast_trace.log available from the Troubleshooting menu of the TUI for Cisco Vision Dynamic Signage Director in the Control logs.
Use a packet sniffer device at Cisco Vision Dynamic Signage Director and/or at the DMP.
Inspect the multicast configuration of the Cisco Connected Venue switch by turning on debug for multicast group subscriptions.
Tip:
It is valuable to know the multicast group/port that a specific DMP should be listening on. This can be validated using the dmpconfig debug feature, by going to the URL:
http://svd-ip:8080/StadiumVision/dmpconfig/000000000000?ipaddr=x.x.x.x,
where x.x.x.x is the IP address of the DMP to be debugged. In the XML output provided, you will see the multicast IP address and port in use.
DMPs Rebooting
DMPs rebooting or becoming unresponsive while per-script multicast is enabled is most likely due to some multicast video port overlap with the ports used for multicast control.
To diagnose this condition:
Inspect all multicast port numbers in the configuration to investigate any multicast group/port overlaps.
Using a packet sniffer, inspect network traffic on a separate box and via port span rather than on a DMP.

What To Do Next
Configuring Multicast Support for Zone-Based Content Synchronization for the SV-4K and DMP-2K
Zone-based content synchronization provides enhanced recovery for video walls if an SV-4K and DMP-2K reboots during the running of a playlist. Zone-based video wall synchronization is an alternative form of synchronization available for SV-4K and DMP-2K devices participating in a video wall. It makes use of a mechanism native to the SV-4K/DMP-2Ks that helps a group of media players stay in content sync with a leader device over multicast.
The general guideline is to use zone-based video wall synchronization for dedicated video walls that are playing video content longer than
15 minutes. While you can use this form of synchronization for all video walls, the synchronization benefit is best seen with longer-playing video wall content.
The default multicast address and ports are automatically configured to support zone-based content synchronization for the SV-4K and
DMP-2K upon installation of the Cisco Vision Dynamic Signage Director software; however, the feature is not enabled by default.
Use this task to change the default multicast values as needed, when you assess your system-wide multicast addressing needs.
Note:
By default, zone-based content synchronization is not enabled for the SV-4K and DMP-2K. For more information, see the “Working with Video Walls” section of the Cisco StadiumVision Director Operations Guide .
To configure multicast support for zone-based content synchronization for the SV-4K and DMP-2K, complete the following steps:
1.
From the Management Dashboard, go to Dynamic Signage Director Configuration > System Configuration > Global DMP
Settings > SV-DMP Common Settings.
2.
Verify that the following default values for the following properties are compatible for your network, and change as required:
—
Content sync multicast address—239.193.0.253
—
Content sync multicast port—50001
3.
Save your changes.
What To Do Next
After you have configured the system settings for your Cisco Vision Dynamic Signage Director servers, be sure to do the following:
Configure the backup environment between your primary and secondary servers. For more information, see Backing Up and Restoring
Cisco Vision Dynamic Signage Director Servers, page 77 .
If you are configuring Cisco Vision Dynamic Signage Director Remote servers:
The centralized Cisco Vision Dynamic Signage Director server is configured by default to use a global account for communication with all Cisco Vision Dynamic Signage Director Remote servers to support monitoring of venues from the Management Dashboard.
Using the default configuration, you can specify a common password to be used by all Cisco Vision Dynamic Signage Director Remote servers.
You can change the default configuration and specify a unique password for each remote server. To do this, you must modify the global credential on the Cisco Vision Dynamic Signage Director server, and then configure a password in the Venues interface from the
Control Panel on the Cisco Vision Dynamic Signage Director server.
Whether you are using a common or unique password, the remote server must be configured to use the same password that is configured on the Cisco Vision Dynamic Signage Director server for that venue.
