You can view and update the following operating system settings:

•IP—the IP addresses and Dynamic Host Configuration Protocol (DHCP) client settings that were entered when the application was installed.

•SMTP—the SMTP host that the operating system uses for sending email notifications.

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.

---

Caution If you change any of these settings, the license MAC value will change if the server is hosted on virtual hardware. You must request a new license with the new license MAC value, upload the new license and restart the License Manager. Cisco recommends that you delete the old license before you request a new one.

---

Procedure

---

Step 1 Sign in to Cisco Unified Communications Operating System Administration.

Step 2 Select Settings > IP > Ethernet.

Step 3 Enter the new values in the appropriate fields to modify the Ethernet settings.

Table 2-1 Ethernet Settings Fields and Descriptions 

Field	Description
DHCP	Indicates whether DHCP is Enabled or Disabled.
Hostname	Shows the name of the host server. 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.

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

---

Step 1 Sign in to Cisco Unified Communications Operating System Administration.

Step 2 Select Settings > IP > Publisher.

Step 3 Enter the new Publisher IP address.

---

Troubleshooting Tips

Following a fresh installation of Cisco Unified Presence, you can change the IP address of the Cisco Unified Communications Manager publisher server. Select System > CUCM Publisher in Cisco Unified Presence Administration

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 sign in to Cisco Unified Presence Administration on the subsequent node. If Cisco Unified Presence does not function properly, follow this procedure:

Procedure

---

Step 1 Sign in directly to 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.

Step 2 Enter your Administrator user name and password and select Submit.

Step 3 Select Settings > IP > Publisher.

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

Step 5 Restart the subsequent node.

Changing NTP Settings

By design, you cannot configure or change the NTP server following a fresh installation of Cisco Unified Presence.

Changing SMTP Settings

Before You Begin

You must configure an SMTP host if you want the system to send you email, for example, from the Certificate Expiry Monitor.

---

Caution If you change the SMTP server, the license MAC value will change if the server is hosted on virtual hardware. You must request a new license with the new license MAC value, upload the new license and restart the License Manager. Cisco recommends that you delete the old license before you request a new one.

---

Procedure

---

Step 1 Sign in to Cisco Unified Communications Operating System Administration.

Step 2 Select Settings > SMTP.

Step 3 Enter or modify the SMTP hostname or IP address.

---

Changing Time Settings

You can manually configure the server time if NTP is currently disabled.

Before You Begin

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

Procedure

---

Step 1 Sign in to Cisco Unified Communications Operating System Administration.

Step 2 Select Settings > Time.

Step 3 Enter the date and time for the system.
