Chapter 9 DMP Access and Security Settings
Procedures
Protect Your DMP from Unauthorized Management
Caution Configure your network firewall to restrict access to DMPs over TCP port 7777. Permit such access from only the DMM
appliance where your fully licensed copy of Cisco Digital Signs is installed. If you do not know how to define an access control list
(ACL), ask the security policy administrator for your network or see the manufacturer documentation for your firewall.
When you use Cisco Digital Signs to manage a network of DMPs centrally, you must configure each
DMP to secure and trust its communication with Cisco Digital Signs.
Before You Begin
• Log in.
Procedure
Step 1 Click Centralized Management in the Settings list.
Step 2 Enter in the Digital Signs Server Timeout (sec) field the maximum number of seconds that your DMP
should wait for a response from your DMM appliance.
Step 3 Enter the routable DMM appliance IP address or DNS-resolvable hostname in the DMM Appliance
IP Address fi
eld.
Note Has Cisco Digital Signs autodiscovered your new DMP? If so, the DMM Appliance IP Address field might already
be populated with the correct information for your DMM appliance.
Step 4 Click Apply to confirm and test your choices.
Your entries are recorded to volatile memory and take effect — but only until you change them or restart
you
r DMP.
Step 5 When you are satisfied that you chose the correct settings, click Save Configuration in the
Administration list, and then click Save.
Your entries take effect permanently and will persist even after your DMP restarts.
Note Your DMM appliance and your DMP use HTTPS to communicate securely over TCP port 7777 when
centralized management is enabled.
Step 6 Stop. You have completed this procedure.
