Operation Manual – NTP
Quidway S5600 Series Ethernet Switches-Release 1510
Note:
When you configure an NTP connection with authentication, it is necessary to add a
specified key after the peer entity or server in the command. Otherwise, the later sent
packets have no authentication information.
The above configuration synchronizes S5600 to Quidway1. As NTP authentication is
not enabled on Quidway1, S5600 will fail to be synchronized to Quidway1.
To synchronize the S5600 series switch, the following configuration is needed for
Quidway1.
# Enable authentication on Quidway1.
[Quidway1] system-view
[Quidway1] ntp-service authentication enable
# Set the MD5 key to 42, with the content being aNiceKey.
[Quidway1] ntp-service authentication-keyid 42 authentication-model md5
aNiceKey
# Specify the key to be a trusted key.
[Quidway1] ntp-service reliable authentication-keyid 42
After the above configuration, the S5600 series switch can be synchronized to
Quidway1. You can view the status of S5600 after the synchronization.

The output information indicates that S5600 is synchronized to Quidway1, with the
clock stratum being 3, one stratum higher than Quidway1.
