Sntp authenticate

Clock Commands

User Guidelines

Multiple keys can be generated.

Example

The following example defines the authentication key for SNTP.

Console(config)# sntp authentication-key 8 md5 ClkKey

The sntp authenticate Global Configuration mode command grants authentication for received Simple Network Time Protocol (SNTP) traffic from servers. To disable the feature, use the no form of this command.

Syntax

sntp authenticate no sntp authenticate

Default Configuration

No authentication

Command Mode

Global Configuration mode

User Guidelines

The command is relevant for both unicast and broadcast.

Example

The following example defines the authentication key for SNTP and grants authentication.

Console(config)# sntp authentication-key 8 md5 ClkKey
