Adding a DNS Server
If you want to configure your Cisco UMG system for VPIM functionality, add a DNS server to your system by following one of these procedures:

Adding a DNS Server: Systems with Cisco Unity
If you are using Cisco UMG with Cisco Unity, you will need to have a DNS server for failover support. The primary/secondary Cisco UMG is transparent to Cisco Unity; however, because this information is configured only on the DNS server, Cisco Unity relies on Microsoft Exchange Simple Mail Transfer Protocol (SMTP) to determine to which Cisco UMG it should send outgoing messages. Cisco Unity should be able to receive messages from both primary and secondary Cisco UMGs if they share the same domain name. Map the Cisco UMG domain name to two IP addresses (primary Cisco UMG and secondary Cisco UMG) in DNS.
Adding a DNS Server: Systems without Cisco Unity
If you are not using Cisco Unity, we recommend that you do not use DNS servers. This improves message exchanging performance, allowing Cisco UMG and endpoints to use IP addresses to address each other instead of by using DNS hostnames. This can be achieved by provisioning peers with IP addresses, or by having each entity cache the resolved IP addresses from the DNS name.
Setting Backup Parameters
About Backup Parameters
Cisco UMG backup and restore functions use an FTP server to store and retrieve data. The backup function copies the files from Cisco UMG to the FTP server and the restore function copies the files from the FTP server to Cisco UMG. The FTP server can reside anywhere in the network as long as the backup and restore functions can access it with an IP address or hostname.
All Cisco UMG backup files are stored on the specified server. You can copy the backup files to other locations or servers, if necessary.
The backup parameters specify the FTP server to use for storing Cisco UMG backup files and the number of backups that are stored before the system overwrites the oldest one.
Note
To backup or restore files, see the "Backing Up and Restoring Data" chapter.

umg-1#Configuring NTP Servers
During the software postinstallation process, the Network Time Protocol (NTP) server may have been configured. If it was not configured, or if you want to change the configuration, use these procedures to add or delete NTP servers. Cisco UMG supports up to three NTP servers.

About Adding NTP Servers
You can specify an NTP server using its IP address or its hostname.
Cisco UMG uses the DNS server to resolve the hostname to an IP address and stores the IP address as an NTP server. If DNS resolves the hostname to more than one IP address, Cisco UMG randomly chooses one of the IP addresses that is not already designated as an NTP server. If you do not want to go with random choice, set the prefer attribute for one server.
To configure an NTP server with multiple IP addresses for a hostname, repeat the configuration steps using the same hostname. Each iteration assigns the NTP server to its remaining IP addresses.

Examples of Adding NTP Servers
The following commands configure the NTP server:

Typically, you set the time zone during installation. If you did not, or if you want to change it, use the clock timezone command in Cisco UMG configuration mode. The system will offer you a range of options to choose from.
To display the time zone, use the show clock command in Cisco UMG EXEC mode.
Example of Setting the Time Zone

About Logging Operations
Cisco UMG captures messages that describe activities in the system. These messages are collected and directed to a messages.log file on the Cisco UMG module hard disk, the console, or an external system log (syslog) server. The messages.log file is the default destination.
This section describes the procedure for configuring an external server to collect the messages.
Note
Prerequisites
Gather the hostname or IP address of the designated log server.
