Add an NTPv4 Server
Add a remote NTP server to the configuration by first specifying its IP address. NTP adds this IP address to a list of servers, which the local NTP client uses to query remote time servers for time information. The list of qualified servers called to is a peer list.
About this task
For NTPv4, this procedure adds the NTP server information to the switch that is acting as an NTP client. You can configure a maximum of 10 IPv4 NTP servers and 10 IPv6 NTP servers.
Procedure
- In the navigation pane, expand .
- Click NTPv4.
- Click the Server tab.
- Click Insert.
- Specify if the IP address is IPv4 or IPv6.
- Specify the IP address of the NTP server.
- Click Insert.
