Updated: September 22, 2026

Want to summarize with AI?

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

Access the HER device using the SSH terminal
Enter the global configuration mode
Example:
```
config t
```
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
          
```

Exit the configuration.

Example:

config t
            ntp server 192.168.1.100
            exit

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
```
Add the new IP address for the hostname:
Example:
```
ip host caserver.fnd.iot.com 192.168.1.100
```

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.
