Settings

This chapter provides information about using the Settings options to display and change IP settings, host settings, and Network Time Protocol (NTP) settings.

IP settings

The IP Settings options allow you to view and change IP and port setting for the Ethernet connection and, on subsequent nodes, to set the IP address of the publisher.

Set up ethernet settings

The IP Settings window indicates whether Dynamic Host Configuration Protocol (DHCP) is active and also provides the related Ethernet IP addresses, as well as the IP address for the network gateway.

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

To view or change the IP settings, follow this procedure:

Procedure
    Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > IP > Ethernet.

    The Ethernet Settings window displays.

    Step 2   To modify the Ethernet settings, enter the new values in the appropriate fields. For a description of the fields on the Ethernet Settings window, see the following table.
    Table 1 Ethernet Configuration Fields and Descriptions

    Field

    Description

    DHCP

    Indicates whether DHCP is Enabled or Disabled.

    Note   

    If you enable DHCP, the Port and Gateway settings get disabled and cannot be changed.

    Hostname

    Displays the host name of the node.

    Note   

    If you run Cisco Unified Communications Manager on a virtualized server and you change this value, you must obtain a replacement license file that is registered to the calculated license Mac based on the new value.

    IP Address

    Displays the IP address of the system.

    Note   

    If you run Cisco Unified Communications Manager on a virtualized server and you change this value, you must obtain a replacement license file that is registered to the calculated license Mac based on the new value.

    Subnet Mask

    Displays the IP subnet mask address.

    Default Gateway

    Shows the IP address of the network gateway.

    Step 3   To preserve your changes, click Save.
    Caution   

    Changing IP address or host of a node can affect system performance. For detailed information, see Changing the IP Address and Host Name for Cisco Unified Communications Manager Release 8.6(1) at http:/​/​cisco.com/​en/​US/​products/​sw/​voicesw/​ps556/​prod_​maintenance_​guides_​list.html.


    Set up IPv6

    Use the following procedure to enable and configure IPv6 on the node.


    Note


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


    Procedure
      Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > IP > Ethernet IPv6.

      The Ethernet IPv6 Configuration window displays.

      Step 2   To modify the Ethernet settings, enter the new values in the appropriate fields. For a description of the fields on the Ethernet IPv6 Configuration window, see the following table.
      Table 2 Ethernet IPv6 Configuration Fields and Descriptions

      Field

      Description

      Enable IPv6

      Check this check box to enable IPv6 on the node.

      Address Source

      Choose one of the following IP address sources:

      • Router Advertisement
      • DHCP
      • Manual Entry/Mask

      Be aware that the three IP address sources are mutually exclusive.

      Note   

      Unless you specify Manual Entry, the IP Address and Mask fields remain read only.

      IPv6 Address

      If you chose Manual Entry, enter the IPv6 address of the node; for example:

      fd6:2:6:96:21e:bff:fecc:2e3a

      IPv6 Mask

      If you chose Manual Entry, enter the IPv6 mask; for example:

      64

      Update with Reboot

      If you want the system to reboot immediately after you click Save, check this check box. If you want to reboot later, leave the check box blank.

      Note   

      For the IPv6 settings to take effect, you must reboot the system.

      Step 3   To preserve your changes, click Save.
      Note   

      If you check the Update with Reboot check box, the system reboots after you click Save. For the IPv6 settings to take effect, you must reboot the system.


      Set up publisher settings

      Be aware that this feature is only applicable if Cisco Unified Communications Manager is installed alone on the node.

      On subsequent or subscriber nodes, you can view or change the IP address of the first node or publisher for the node.


      Note


      For detailed instructions about changing the IP address and hostname of nodes in a cluster, see Changing the IP Address and Host Name for Cisco Unified Communications Manager.


      To view or change the publisher IP settings, follow this procedure:

      Procedure
        Step 1   From the Cisco Unified Communications Operating System Administration window, navigate to Settings > IP > Publisher.

        The Publisher Settings window displays.

        Note   

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

        Step 2   Enter the new publisher IP address.
        Step 3   Click Save.

        Set up IP address

        If the IP address of the first Cisco Unified Communications Manager node gets changed while a subsequent node is offline, you may not be able to log in to Cisco Unified Communications Manager Administration on the subsequent node. If this occurs, follow this procedure:

        Procedure
          Step 1   Log in directly to operating system administration on the subsequent node by using the following IP address:

          http://node-name/iptplatform

          where node-name specifies the host name or IP address of the subsequent node.

          Step 2   Enter your Administrator user name and password and click Submit.
          Step 3   Navigate to Settings > IP > Publisher.
          Step 4   Enter the new IP address for the publisher and click Save.
          Step 5   Restart the subsequent node.

          Set up NTP servers

          Ensure that external NTP servers are stratum 5 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 displays.

            Step 2   You can 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.

            Note   

            If you run Cisco Unified Communications Manager on a virtualized server and you change this value, you must obtain a replacement license file that is registered to the calculated license MAC based on the new value.

            1. To delete an NTP server, check the check box in front of the appropriate server and click Delete.
            2. To add an NTP server, click Add, enter the hostname or IP address, and then click Save.
            3. 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 display the correct status.

            Step 3   To refresh the NTP Server Settings window and display the correct status, choose Settings > NTP.
            Note   

            After deleting, modifying, or adding the NTP server, you must restart all other nodes in the cluster for the changes to take affect.


            Set up SMTP settings

            The SMTP Settings window allows you to view or set the SMTP hostname and indicates whether 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 displays.

              Step 2   Enter or modify the SMTP hostname or IP address.
              Step 3   Click Save.

              Set up time settings

              To manually configure the time, follow this procedure:


              Note


              Before you can manually configure the server time, you must delete any NTP servers that you have configured.



              Caution


              If you enter a time that is before the time when Cisco Unified Communications Manager was installed on the server, the digital certificates that the server uses for security become invalid, causing the web server (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 Cisco Unity Connection 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.
