Configuring an NTP Server and Peer
Purpose
Forms an association with a server.
Use the key keyword to configure a key to be used while
communicating with the NTP server. The range for the key-id
argument is from 1 to 65535.
Use the maxpoll and minpoll keywords to configure the
maximum and minimum intervals in which to poll a server. The
range for the max-poll and min-poll arguments is from 4 to 16
seconds, and the default values are 6 and 4, respectively.
Use the prefer keyword to make this server the preferred NTP
server for the device.
Use the use-vrf keyword to configure the NTP server to
communicate over the specified VRF. The vrf-name argument
can be default, management, or any case-sensitive,
alphanumeric string up to 32 characters.
If you configure a key to be used while communicating
Note
with the NTP server, make sure that the key exists as a
trusted key on the device.
Forms an association with a peer. You can specify multiple peer
associations.
Use the key keyword to configure a key to be used while
communicating with the NTP peer. The range for the key-id
argument is from 1 to 65535.
Use the maxpoll and minpoll keywords to configure the
maximum and minimum intervals in which to poll a peer. The
range for the max-poll and min-poll arguments is from 4 to 17
seconds, and the default values are 6 and 4, respectively.
Use the prefer keyword to make this peer the preferred NTP
peer for the device.
Use the use-vrf keyword to configure the NTP peer to
communicate over the specified VRF. The vrf-name argument
can be default, management, or any case-sensitive,
alphanumeric string up to 32 characters.
(Optional)
Displays the configured server and peers.
Note A domain name is resolved only when you have a DNS
server configured.
(Optional)
Copies the running configuration to the startup configuration.
