The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
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.
This section also describes how to change time settings and correct time zone data.
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.
If, for network configuration purposes, you changed the IP address or hostname on the IM and Presence Service database publisher node, then you will need to update the IP address of the IM and Presence Service database publisher node on IM and Presence Service subscriber nodes.
Use this functionality only if you want an IM and Presence Service subscriber node to point to a different IM and Presence Service database publisher node. If this node is the IM and Presence Service database publisher node, be aware that you cannot use this window to change the IP address.
If the IP address of the IM and Presence database publisher node changes while an IM and Presence subscriber node is offline, be aware that you may not be able to sign in to Cisco Cisco Unified Communications Manager IM and Presence Administration on the IM and Presence subscriber node. Complete this procedure if IM and Presence does not function properly.
Step 1 | Sign in directly to Cisco Unified IM and Presence Operating System Administration on the subsequent node by using the following URL:http://node-name/cmplatform where node-name specifies the hostname or IP address of the IM and Presence subscriber node. |
Step 2 | Enter your Administrator user name and password and select Submit. |
Step 3 | Select . |
Step 4 | Enter the new IP address for the IM and Presence database publisher node and select Save. |
Step 5 | Restart the IM and Presence subscriber node. |
By design, you cannot configure or change the NTP server following a fresh installation of the IM and Presence Service.
You must configure an SMTP host if you want the system to send you email, for example, from the Certificate Expiry Monitor.
You can manually configure the node time if NTP is currently disabled.
Before you can manually configure the node time, you must delete any NTP servers that you have configured.
The IM and Presence Service includes the latest time zone information and Cisco contacts you about major time zone events. After you install the IM and Presence Service, you can download a COP file with the latest updates. For more information on how to correctly upgrade your time zone data, see the Release Notes for Cisco Unified Communications Manager on Cisco.com.
