Before you use the command, make sure NTP authentication is enabled and an authentication key is
configured. The key automatically changes to untrusted after you delete the key. In this case, you do not
need to execute the
undo ntp-service reliable authentication-keyid
command.
You can set up to 128 keys by executing the command.
Examples
# Enable NTP authentication, specify the MD5 algorithm, with the key ID of 37 and key value of
BetterKey
.
<Sysname> system-view
[Sysname] ntp-service authentication enable
[Sysname] ntp-service authentication-keyid 37 authentication-mode md5 BetterKey
# Specify this key as a trusted key.

ntp-service source
Use
ntp-service source
to specify the source interface for NTP messages.
Use
undo ntp-service source
to restore the default.
Syntax
ntp-service source
interface-type interface-number
undo ntp-service source
Default
No source interface is specified for NTP messages. The device searches the routing table for the
outbound interface of NTP messages, and uses the primary IP address of the outbound interface as the
source IP address for NTP messages.
Views
System view
Predefined user roles
network-admin
Parameters
interface-type interface-number
: Specifies an interface by its type and number.
Usage guidelines
If you specify the source interface for NTP messages, the device sets the source IP address of the NTP
messages as the primary IP address of the specified interface when sending the NTP messages.
When the device responds to an NTP request, the source IP address of the NTP response is always the
IP address of the interface that has received the NTP request.
If you do not want the IP address of an interface on the local device to become the destination address
for response messages, use this command.
