Settings
Use 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.
This section contains the following topics:
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 IP settings, do the following procedure.
Do not use the procedure to change IP settings for Cisco Unity Connection.
For information on changing the IP address of a Connection server, see the “Changing the IP Addresses of Cisco Unity Connection Servers” Upgrade Guide for Cisco Unity Connection at http://www.cisco.com/en/US/products/ps6509/prod_installation_guides_list.html.
For information on changing the host name of a Unity Connection 10.x server, Install, Upgrade, and Maintenance Guide for Cisco Unity Connection 10x at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/install_upgrade/guide/10xcuciumgx.html.
Step 1 From the Cisco Unified Communications Operating System Administration window, navigate to Settings > IP > Ethernet.
The Ethernet Settings window displays.For a description of the fields on the Ethernet Settings window, see Table 4-1 .

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.
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 should be NTP v4 (version 4). If you are usingIPv6 addressing, external NTP servers must be NTP v4.
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.
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:
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.
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. See the “NTP Servers” section for more information.
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 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.
