Use the Settings options to display and change IP settings,
host settings, and Network Time Protocol (NTP) settings.
Caution
Modifying system parameters such as Time zone, Network Time Protocol
(NTP), NIC speed, IP Address, IP Mask, Gateway Address, Primary DNS, SMTP
server, and Certificate Information (Organization, Unit, Location, State,
Country) can change the License MAC thereby invalidating current License files. You
must acquire rehosted license files (with new License MAC) in such cases within
30-day grace period, or the system stops working.
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.
Update the values in the fields only if you are changing the IP
address. Host name change is not supported in Unified CCX 9.0(1). For detailed
instructions about changing the IP address of servers in a cluster, see the
Cisco Unified CCX Administration Guide, Release 9.0(1).
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.
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 appears.
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 the table
"Ethernet Configuration Fields and Descriptions" below.
Step 3
To preserve your changes, click
Save.
Caution
Changing IP address of a server can affect system performance.
For more information, see the
Cisco Unified CCX Administration Guide, Release
9.0(1).
Caution
Host name change is not supported in Unified CCX 9.0(1).
Table 1 Ethernet configuration fields and descriptions
Field
Description
Hostname
Displays the host name of the server.
Note
If you run Unified CCX on a virtualized server and
you change this value, you must obtain a replacement license file that is
registered to the calculated license MAC based on the new value.
IP Address
Displays the IP address of the system.
Note
If you run Unified CCX on a virtualized server and
you change this value, you must obtain a replacement license file that is
registered to the calculated license MAC based on the new value.
Subnet Mask
Displays the IP subnet mask address.
Default Gateway
Shows the IP address of the network gateway.
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. Host name change is not supported in Unified CCX 9.0(1). For detailed
instructions about changing the IP address of servers in a cluster, see the
Cisco Unified CCX Administration Guide, Release 9.0(1).
To view the publisher IP settings, follow this procedure:
Procedure
From the Cisco Unified Communications Operating System
Administration window, navigate to
Settings > IP > Publisher.
The
Publisher Settings window appears.
Note
You can view the publisher IP address only on
the subsequent node of the cluster, not on the
publisher itself.
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.
Procedure
Step 1
From the Cisco Unified Communications Operating System
Administration window, navigate to
Settings > NTP
Servers.
The
NTP Server Settings window appears.
Step 2
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 must
be NTP v4 (version 4). If you are using IPv6 addressing, external NTP servers
must be NTP v4.
To delete an NTP
server, select the check box in front of the appropriate server, and then 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 view the correct status.
Step 3
To refresh the
NTP Server Settings window and view the
correct status, choose
Settings > NTP.
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.
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 appears.
Step 2
Enter or modify the SMTP hostname or IP address.
Step 3
Click
Save.
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.
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 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.
