4.2.4 Specify Reliable Key
You must specify a key to be a reliable one before it can be used for authentication.
For example, if two routers want to use keyid 1 for authentication, both of them must
specify it to be a reliable one.
Perform the following configuration in system view.
Table 4-9 Specify a key to be a reliable key
Operation Command
Specify a key to be a
reliable key
ntp-service reliable authentication-keyid key-number
Remove a reliable key
undo ntp-service reliable authentication-keyid key-number
The argument key-number is in the range of 1 to 4294967295.
4.2.5 Specify a Local Interface for Sending NTP Messages
This task specifies an interface whose IP address will be used as the source IP
address carried in all the NTP messages sent from the local router to the time server.
Perform the following configuration in system view.
Table 4-10 Set a local interface for sending NTP messages
Operation Command
Set a local interface for sending NTP
messages
ntp-service source-interface
{
interface-name
|
interface-type interface-number
}
Disable the interface as the interface for
sending NTP messages
undo ntp-service source-interface
You can specify an interface by specifying its interface-name or interface-type
interface number. The router will use the IP address of the interface as the source IP
address carried by the NTP messages sent to the time server. The outgoing interface
specified using the command ntp-service unicast-server or ntp-service
unicast-peer, if there is any, will be preferred in case there is any difference.
4.2.6 Set NTP Master Clock
This task specifies an external reference clock or the local clock as the NTP master
clock.
