How to Change IP Settings

You can view and update the IP addresses and Dynamic Host Configuration Protocol (DHCP) client settings that were entered when the application was installed.


Changing Ethernet Settings

You can determine whether Dynamic Host Configuration Protocol (DHCP) is active and locate the related Ethernet IP addresses, as well as the IP address for the network gateway.


Before You Begin
  • All Ethernet settings apply only to Eth0. You cannot configure any settings for Eth1. The Maximum Transmission Unit (MTU) on Eth0 defaults to 1500.
  • Changing the Ethernet settings causes an immediate system restart.


Procedure
  1. Log in to Cisco Unified Operating System Administration.
  2. Select Settings > IP > Ethernet.
  3. Enter the new values in the appropriate fields to modify the Ethernet settings.
Table: Ethernet Settings Fields and Descriptions
Field Description

DHCP

Indicates whether DHCP is Enabled or Disabled.

Hostname

Shows the name of the host server.

Note: You can only change the hostname after changes to these configuration settings are complete:

  • DNS
  • Cisco Unified Communications Manager Application Server List
  • Cisco Unified Presence Topology

IP Address

Shows the IP address of the system.

Note: Changing the IP address or host on the Cisco Unified Presence publisher server can affect system performance.

Subnet Mask

Shows the IP subnet mask address.

Default Gateway

Shows the IP address of the network gateway.

4. Click Save to commit your changes.

Troubleshooting Tips

If you enable DHCP, the system disables the Port and Gateway setting, and it cannot be changed.


Changing the IP Publisher Node Address on Subsequent Nodes

If, for network configuration purposes, you changed the IP address or hostname on the Cisco Unified Presence publisher node, then you will need to update the IP address of the publisher node on subsequent nodes in Cisco Unified Presence.


Before You Begin

Use this functionality only if you want a subsequent node in Cisco Unified Presence to point to a different Cisco Unified Presence publisher node. If this node is the Cisco Unified Presence publisher node, be aware that you cannot use this window to change the IP address.


Procedure
  1. Log in to Cisco Unified Operating System Administration.
  2. Select Settings > IP > Publisher.
  3. Enter the new Publisher IP address.
  4. Click Save.


Troubleshooting Tips

Following a fresh installation of Cisco Unified Presence, you can change the IP address of the Cisco Unified Communications Manager publisher server.



Troubleshooting IP Publisher Node Address Change on a Subsequent Node

Before You Begin

If the IP address of the Cisco Unified Presence publisher node changes while a subsequent node is offline, be aware that you may not be able to log in to Cisco Unified Presence Administration on the subsequent node. If Cisco Unified Presence does not function properly, follow this procedure:


Procedure

1. Log in directly to Cisco Unified Operating System Administration on the subsequent node by using the following URL:

http://server-name/cmplatform
where server-name specifies the host name or IP address of the subsequent node.

2. Enter your Administrator user name and password and click Submit.

3. Select Settings > IP > Publisher.

4. Enter the new IP address for the publisher server and click Save.

5. Restart the subsequent node.

Configuring an NTP Server

This procedure only applies if you use Cisco Unified Presence Release 7.0(1) or 7.0(2). By design, NTP is not configurable on Cisco Unified Presence Release 7.0(3) or a higher release.


Before You Begin
  • You can add or delete an external NTP server. You can only configure the NTP server settings on the publisher server.
  • Ensure that external NTP server is stratum 9 or higher (1-9).


Procedure
  1. Log in to Cisco Unified Operating System Administration.
  2. Select Settings > NTP Servers.
  3. Perform one of the following actions:
If you want to: Action

Add an NTP server

  1. Click Add New.
  2. Enter the hostname or IP address.
  3. Click Save.

Delete an NTP server

  1. Check the appropriate server.
  2. Click Delete Selected.

Refresh the NTP server

Select Settings > NTP Servers.

Troubleshooting Tips
  • After deleting, modifying, or adding NTP server, you must restart all the other nodes in the cluster for the changes to take effect.
  • Changes to the NTP servers can take up to five minutes to complete. Whenever you make any change to the NTP servers, you must refresh the window to display the correct status.
