Settings

Use the Settings options to display and change IP settings, host settings, and Network Time Protocol (NTP) settings.


Caution


Modifying system parameters such as Time zone, Network Time Protocol (NTP), NIC speed, IP Address, IP Mask, Gateway Address, Primary DNS, SMTP server, and Certificate Information (Organization, Unit, Location, State, Country) can change the License MAC thereby invalidating current License files. You must acquire rehosted license files (with new License MAC) in such cases within 30-day grace period, or the system stops working.


IP and port settings

Use the IP Settings option to view and change IP and port setting for the Ethernet connection on the subsequent node and configure the IP address of the publisher.

This section contains the following topics:


Note


Update the values in the fields only if you are changing the IP address. Host name change is not supported in Unified CCX 9.0(x). For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified CCX Administration Guide.


Change IP settings

Use the IP Settings window to change or view the related Ethernet IP addresses, as well as the IP address for the network gateway.

All Ethernet settings apply to ethernet interface Eth0 or Eth1. You cannot configure any settings for Eth1. The Maximum Transmission Unit (MTU) on Eth0 defaults to 1500.

For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified CCX Administration Guide, available here:

View Publisher IP Settings

You can view the IP address of the first node or publisher for the node on the subsequent node.


Note


Update the values in the fields only if you are changing the IP address. For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified CCX Administration Guide.


To view the publisher IP settings, follow this procedure:

Procedure
From the Cisco Unified Communications Operating System Administration window, navigate to Settings > IP > Publisher.

The Publisher Settings window appears.

Note   

You can view the publisher IP address only on the subsequent node of the cluster, not on the publisher itself.


Configure NTP servers

Ensure that external NTP servers are stratum 9 or higher (1-9). To add, delete, or modify an external NTP server, follow this procedure:


Note


You can only configure the NTP server settings on the first node or publisher.


Procedure
    Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > NTP Servers. The NTP Server Settings window appears.
    Step 2   Add, delete, or modify an NTP server:
    Note   

    To avoid potential compatibility, accuracy, and network jitter problems, the external NTP servers that you specify for the primary node must be NTP v4 (version 4). If you are using IPv6 addressing, external NTP servers must be NTP v4.

    • To delete an NTP server, select the check box in front of the appropriate server, and then click Delete.
    • To add an NTP server, click Add, enter the hostname or IP address, and then click Save.
    • To modify an NTP server, click the IP address, modify the hostname or IP address, and then click Save.
    Note   

    Any change that you make to the NTP servers can take up to 5 minutes to complete. Whenever you make any change to the NTP servers, you must refresh the window to view the correct status.

    Step 3   To refresh the NTP Server Settings window and view the correct status, choose Settings > NTP. After deleting, modifying, or adding the NTP server, you must restart the other node in the cluster for the changes to take effect.

    Set SMTP settings

    Use the SMTP Settings window to view or set the SMTP hostname and determine if the SMTP host is active.


    Tip


    If you want the system to send you e-mail, you must configure an SMTP host.


    To access the SMTP settings, follow this procedure:

    Procedure
      Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > SMTP. The SMTP Settings window appears.
      Step 2   Enter or modify the SMTP hostname or IP address.
      Step 3   Click Save.

      Set Time

      To manually configure the time, follow this procedure:


      Note


      The time cannot be set if NTP is currently enabled. Before you can manually configure the server time, you must delete any NTP servers that you configured.



      Caution


      If you enter a time that is before the time when Unified CCX was installed on the server, the digital certificates that the server uses for security become invalid, causing the webserver (Tomcat) to stop working. If this happens, you must regenerate the certificates.


      Procedure
        Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > Time.
        Step 2   Enter the date and time for the system.
        Step 3   Click Save.
        Step 4   On a Unified CCX server, if you changed the date or if you changed the time by more than two minutes, use the CLI command utils system restart to restart the server.
