Configuring NTP Servers
Examples
The following commands configure the DNS server:
se-10-0-0-0# config t
se-10-0-0-0(config)# ip domain-name mycompany
se-10-0-0-0(config)# ip name-server 10.100.10.130 10.5.0.0
se-10-0-0-0(config)# exit
se-10-0-0-0#
The output from the show hosts command might look similar to the following:
se-10-0-0-0# show hosts
Hostname: se-10-100-6-10
Domain: mycompany
DNS Server1: 10.100.10.130
se-10-0-0-0#
Configuring NTP Servers
During the software postinstallation process, the Network Time Protocol (NTP) server may have been
configured. Cisco Unity Express accepts a maximum of three NTP servers. Use this procedure to add or
delete NTP servers.
Adding NTP Servers
You can designate an NTP server using its IP address or its hostname.
Cisco Unity Express 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 Unity Express randomly chooses one of the IP addresses that is not already designated as an NTP
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.
