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:

Prerequisites for Configuring NTP on Cisco Vision Dynamic Signage Director Servers and DMPs, page 17 (required)

Configuring the System Date and Time Using NTP on Cisco Vision Dynamic Signage Director Servers, page 18 (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.

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.

Configuring the Cisco Vision Dynamic Signage Director Server System Settings
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.
6. To save your changes, type :wq.
The configuration is saved and the ntpd service is restarted. Verify that you see the “OK” confirmation that the ntpd has started.
7. To return to the Date and Time Settings menu, press any key.
Configuring the Time Zone
Configuring the time zone is required for both the Cisco Vision Dynamic Signage Director and Cisco Vision Dynamic Signage Director
Remote servers.
Note: Although there is an option to set the time zone in the Venues interface of the Control Panel on the Cisco Vision Dynamic Signage

Verifying Time Synchronization on the Cisco DMP 4310G
You can find DMPs that are having problems synchronizing with the NTP server using the DMP compliance check in the Management
Dashboard.
Before you can run a valid DMP compliance check for the DMP synchronization status, the “Synchronized to server svd-ip at stratum n”
value of the NTP status global DMP properties must reflect the IP address of your NTP host and its stratum level.

How to Configure Cisco Vision Dynamic Signage Director Server System Settings
Note: Outside of Cisco Vision Dynamic Signage Director, if you know the DMP IP address, you can find a single DMP’s NTP status using
a web browser and going to either of the following URLs:
http://dmpIpAddress
https://dmpIpAddress/get_param?p=*
Find “ntpc.status”. A sample line depicting unsuccessful time synchronization is:
ntpc.status T_STRING Not Synchronized
To verify time synchronization on the Cisco DMP 4310G, complete the following steps:
1. Do one of the following to find and confirm the stratum level for the NTP host:
If you are using the Cisco Vision Dynamic Signage Director server as the NTP host:
—
Log into the TUI and go to Troubleshooting > NTP > Local clock state (Figure 11 on page 28).
Figure 11
Stratum Field in Local Clock State TUI Output
Note: Alternatively, you can run a DMP Get Status command on one of the DMPs from the Management Dashboard and find the value
reported in it ntpc.status MIB value.
If you are using an NTP host other than the Cisco Vision Dynamic Signage Director server:
—
Log into the TUI and go to Troubleshooting > NTP > Show configured peers and clients. Find the configured NTP host in the
“refid” field and its corresponding stratum level under the “st” column.
Figure 12
Stratum Field in Show Configured Peers and Clients Output
2. 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.
See Modifying the Standard NTP Configuration Globally on all Cisco DMP 4310Gs, page 24 for more information.
3. Go to the Management Dashboard.

4. Click DMP and TV Controls > Monitoring > Get Status.
5. At the bottom of the screen, go to Status > Compliance.
6. Find ntpc.status MIB and look for information about the synchronization status, such as “Not synchronized.”
If your DMPs are not synchronized, see What To Do Next, page 29.
What To Do Next
If you find that DMPs are not synchronized:

Confirm that you have met the requirements described in Prerequisites for Configuring NTP on Cisco Vision Dynamic Signage
Director Servers and DMPs, page 17.

Verify your NTP host configuration to be sure that the proper IP address is configured.

Verify reachability of the NTP server from the DMPs in your Cisco Vision Dynamic Signage Director network.
For more information about other NTP troubleshooting on your network, look up NTP debugging techniques provided by the ntp.org project
on the world wide web.
Note: After you verify DMP NTP synchronization, be sure to reset the NTP status field back to $svd_ignore because the stratum value can
change.
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

Modifying the Standard NTP and PTP Configuration on All SV-4K and DMP-2Ks in the System, page 31 (optional)

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.
29
Configuring the Cisco Vision Dynamic Signage Director Server System Settings
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.

Server Administration Guide, Release 3.1.
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 Table 3 on page 31.

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.

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: Be sure to use the value that is configured in your Cisco Connected Venue network for Cisco Vision Dynamic Signage Director
control messages and include the :port. The recommended default is :50001.
4. Click Apply.
Configuring Per-Script Multicast in Cisco Vision Dynamic Signage Director
By default, Per-Script Multicast Optimization is disabled and the Cisco Vision Dynamic Signage Director server sends all communication

DMPs.
To configure per-script multicast, complete the following steps:
1. From the Management Dashboard, select Tools > Advanced > Registry.
2. To enable per-script multicast, change the values of the following registry keys:
—
transport.dynamic.enable—Specify a value of true.
—
transport.dynamic.send_range—(As Required) Change the range of ports to comply with your network configuration. The
default is 50080-50099.
Note: Be sure that these ports do not overlap with other multicast ports in use on your network.

b. Select all of the DMP devices where the command should be applied.
c. Click the Play button to run the command on the selected devices.
5. To verify the configuration:
a. Start and stop event scripts and change states.
b. Verify that the multicast port that the DMP is listening on is one of the per-script ports (50080-50099 by default), rather than the
global multicast hostport (50001).
If the scripts do not start and stop, see Troubleshooting Per-Script Multicast Configuration, page 39.
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

DMPs Rebooting, 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.
