Changing IP Address on a Subsequent Cisco Unified Communications Manager Node

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 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. For detailed information, see Changing the IP Address and Host Name for Cisco Unified Communications Manager Release 8.0(2) at
http://cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html.

Procedure


Table 4-1 Ethernet Configuration Fields and Descriptions 

Field
Description

DHCP

Indicates whether DHCP is Enabled or Disabled.

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

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


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 Table 4-2.

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.



Table 4-2 Ethernet IPv6 Configuration Fields and Descriptions 

Field
Description

Enable IPv6

Check this check box to enable IPv6 on the server.

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 server; 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.


Publisher Settings

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 servers in a cluster, see Changing the IP Address and Host Name for Cisco Unified Communications Manager Release 8.0(2) at http://cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html.


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.


Changing IP Address on a Subsequent Cisco Unified Communications Manager Node

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://server-name/iptplatform

where server-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.


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 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

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

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 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.
