Item Description
Key 1
Set NTP authentication key.
The NTP authentication feature should be enabled for a system running
NTP in a network where there is a high security demand. This feature
enhances the network security by means of client-server key
authentication, which prohibits a client from synchronizing with a
device that has failed authentication.
You can set two authentication keys, each of which is composed of a
key ID and key string.
• ID is the ID of a key.
• Key string is a character string for MD5 authentication key.

NTP Server
1/Reference
Key ID
Specify the IP address of an NTP server, and configure the
authentication key ID used for the association with the NTP server. The
device synchronize its time to the NTP server only if the key provided by
the server is the same with the specified key.
You can configure two NTP servers. The clients will choose the optimal
reference source.
IMPORTANT:
The IP address of an NTP server is a unicast address, and cannot
be a broadcast or a multicast address, or the IP address of the
local clock source.

System time configuration example
Network requirements
• As shown in Figure 53 , the local clock of Switch is set as the reference clock.
• AC operates in client mode, and uses Switch as the NTP server.
• NTP authentication is configured on both AC and Switch.

Configuring the switch
Configure the local clock as the reference clock, with the stratum of 2, configure authentication, with the
key ID of 24, and trusted key as aNiceKey. (Details not shown.)
Configuring the AC
To configure Switch as the NTP server of AC:
1. Select Device > System Time from the navigation tree.
2. Click the Net Time tab.
The Net Time tab page appears.
