Configuring Global Trusted Key Id For The Ntp; Configuring Ntp Server - D-Link xStack DGS-3610 Series Configuration Manual

DGS-3610 Series Configuration Guide
Command
ntp authentication-key key-id md5
key-string [enc-type]
no ntp authentication-key key-id md5
key-string [enc-type]
The configuration of global authentication key does not mean the key is effective; therefore,
the key must be configured as global trusted key before using it.
Caution
23.2.3 Configuring Global Trusted Key ID
for the NTP
The last step to configure the global security authentication is to set a global authentication
key as a global trusted key. Only by this trusted key the user can send encrypted data and
check the validity of the message.
To specify a global trusted key, run the following commands in the global configuration
mode:
Command
ntp trusted-key key-id
no ntp trusted-key key-id
The above-mentioned three steps of settings are the first procedure to implement security
authentication mechanism. To initiate real encrypted communication with client server, a
trusted key must be set for corresponding server.
Caution
23.2.4

Configuring NTP Server

No NTP server is configured by default. DGS-3610 series's client system supports
simultaneous interaction with up to 20 NTP servers, and one authentication key can be set
for each server to initiate encrypted communication with the server.(after relevant settings of
global authentication and key are completed)
The current version in DGS-3610 series can support the authentication
key up to 1024 and only one key can be set for each server for secure
communication.
When a global authentication key is removed, its all trusted information are
removed.
