Updated: February 4, 2026

Overview

Use this task to configure the NTP server and IP host entries on a HER device to ensure accurate time synchronization and proper hostname resolution within your network.

Follow these instructions to configure the NTP server and IP host entries on HER devices:

Procedure

1.

Access the HER device using the SSH terminal
2.

Enter the global configuration mode

Example:

config t
3.

Use the ntp server command to specify the IP address or hostname of the NTP server.

Example:

ntp server 192.168.1.100
            ntp server ntp.example.com
4.

Exit the configuration.

Example:

config t
            ntp server 192.168.1.100
            exit
5.

To remove an existing IP host entry, use the no form of the  ip host  command:

Example:

no ip host caserver.fnd.iot.com 192.168.1.100
6.

Add the new IP address for the hostname:

Example:

ip host caserver.fnd.iot.com 192.168.1.100
7.

Exit the configuration.

Example:

config t
            ip host fndserver.fndiot.com 192.168.1.100
            exit

You've successfully configured the NTP servers and IP host entires.
