IP and Port Settings
Use the IP Settings option to view and change IP and port setting for the Ethernet connection on the subsequent node and configure the IP address of the publisher.
This section contains the following topics:
Note | Update the values in the fields only if you are changing the IP address. For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified Contact Center Express Administration Guide. |
Change IP Settings
Use the IP Settings window to change or view the related Ethernet IP addresses, as well as the IP address for the network gateway.
All Ethernet settings apply to ethernet interface Eth0 or Eth1. You cannot configure any settings for Eth1. The Maximum Transmission Unit (MTU) on Eth0 defaults to 1500.
For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified Contact Center Express Guide, available here:
IPv6 Configuration
Use the Ethernet Ipv6 Configuration page to enable or disable IPv6 address.
What to Do Next
If you have enabled IPv6 address then add the IPv6 address in the Unified CCX Administration page immediately after server is restarted. If you have disabled IPv6 address then remove the IPv6 address in the Unified CCX Administration page immediately after server is restarted.
For more information, see the Access Server Menu chapter in Cisco Unified Contact Center Express Administration Guide available here:
View Publisher IP Settings
You can view the IP address of the first node or publisher for the node on the subsequent node.
Note | Update the values in the fields only if you are changing the IP address. For detailed instructions about changing the IP address of servers in a cluster, see the Cisco Unified CCX Administration Guide. |
Configure 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. |
Step 1 | From the Cisco Unified Communications Operating System Administration window, navigate to The . NTP Server Settings window appears. | ||||
Step 2 | Add, delete, or modify an NTP server:
| ||||
Step 3 | To refresh the NTP Server Settings window and view the correct status, choose . After deleting, modifying, or adding the NTP server, you must restart the other node in the cluster for the changes to take effect. |
Set SMTP settings
Use the SMTP Settings window to view or set the SMTP hostname and determine if the SMTP host is active.
Tip | If you want the system to send you e-mail, you must configure an SMTP host. |
Set Time
To manually configure the time, follow this procedure:
Note | The time cannot be set if NTP is currently enabled. Before you can manually configure the server time, you must delete any NTP servers that you configured. |
Caution | If you enter a time that is before the time when Unified CCX was installed on the server, the digital certificates that the server uses for security become invalid, causing the webserver (Tomcat) to stop working. If this happens, you must regenerate the certificates. |
Step 1 | From the Cisco Unified Communications Operating System Administration window, navigate to . |
Step 2 | Enter the date and time for the system. |
Step 3 | Click Save. |
Step 4 | On a Unified CCX 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. |
