Parameters
server-name
: Specifies the host name of the NTP server, a case-insensitive string of 1 to 253
characters.
ip-address
: Specifies the IP address of the NTP server. It must be a unicast address, rather than a
broadcast address, a multicast address, or the IP address of the local clock.
vpn-instance
vpn-instance-name
: Specifies the MPLS L3VPN to which the NTP server belongs,
where
vpn-instance-name
is a case-sensitive string of 1 to 31 characters. If the NTP server is on the
public network, do not specify this option.
authentication-keyid
keyid
: Specifies the key ID to be used for sending NTP messages to the NTP
server, where
keyid
is in the range of 1 to 4294967295. If the option is not specified, the local device
and NTP server do not authenticate each other.
priority
: Specifies this NTP server as the first choice under the same condition.
source
interface-type interface-number
: Specifies the source interface for NTP messages. For an
NTP message the local device sends to the NTP server, the source IP address is the primary IP
address of this interface. The
interface-type interface-number
argument represents the interface
type and number.
version
number
: Specifies the NTP version. The value range for the
number
argument is 1 to 4, and
the default is 4.
