H3C S5600 Series Ethernet Switches-Release 1510
Chapter 1 NTP Configuration
1-22
To synchronize the S5600 series switch, the following configuration is needed for
H3C1.
# Enable authentication on H3C1.
[H3C1] system-view
[H3C1] ntp-service authentication enable
# Set the MD5 key to 42, with the content being aNiceKey.
[H3C1] ntp-service authentication-keyid 42 authentication-model md5 aNiceKey
# Specify the key to be a trusted key.
[H3C1] ntp-service reliable authentication-keyid 42
After the above configuration, the S5600 series switch can be synchronized to H3C1.
You can view the status of S5600 after the synchronization.
