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 Table 4-1.


Note Do not enable DHCP for this server; Cisco Unified Mobility Advantage does not use DHCP. If you enable DHCP, the Port and Gateway settings get disabled and cannot be changed.


Step 3 To preserve your changes, click Save.


Caution Changing IP address or host of a server can affect system performance.

Procedure


Table 4-1 Ethernet Configuration Fields and Descriptions 

Field
Description

DHCP

Indicates whether DHCP is Enabled or Disabled. DHCP should be disabled for Cisco Unified Mobility Advantage.

Hostname

Displays the host name of the server.

IP Address

Displays the IP address of the system.

Subnet Mask

Displays the IP subnet mask address.

Default Gateway

Shows the IP address of the network gateway.


Ethernet IPv6 Configuration Settings

This option does not apply to Cisco Unified Mobility Advantage.

Publisher Settings

You do not need to change Publisher settings for Cisco Unified Mobility Advantage.

NTP Servers

Cisco strongly recommends that you use a network time protocol (NTP) server to synchronize all of the servers in your Cisco Unified Mobility Advantage deployment.

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 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.


To delete an NTP server, check the check box in front of the appropriate server and 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 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


Note This setting is not related to the SMTP setting in the Cisco Unified Mobility Advantage Admin Portal, which is used to send messages to clients.


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.


Time Settings

Cisco strongly recommends that you use a network time protocol (NTP) server to synchronize all of the servers in your Cisco Unified Mobility Advantage deployment, instead of manually configuring the time.

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.


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 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.
