3Com Router Command Reference Guide Addendum for V1.2

In the event that authentication has been enabled, this command can be used for specifying one or more keys to be reliable. In other words, clients will only synchronize its clock to the server providing a reliable key. Otherwise, clients will refuse synchronization.

Example

Enable NTP authentication, adopt MD5 encryption, set key ID to 37, configure the key as BetterKey and specify the key to be reliable.

[3Com] ntp-service authentication enable

[3Com] ntp-service authentication-keyid 37 authentication-mode md5 BetterKey

[3Com] ntp-service reliable authentication-keyid 37

Syntax

ntp-servicesource-interface{ interface-name interface-type interface-number }

undo ntp-service source-interface

View

System view

Parameter

interface-name: Interface name. The IP address of the interface will be used as the source IP address of the messages.

interface-type: Interface type, which identifies an interface along with interface-number.

interface-number: Interface number, which identifies an interface along with interface-type.

Description

Using the ntp-servicesource-interfacecommand, you can specify a local interface for NTP message transmission. Using the undo ntp-servicesource-interfacecommand, you can remove the current setting.

Source address will be determined depending on the output interface.

Using this command, you can specify a source IP address to be carried by all the transmitted NTP messages by specifying the interface. This command is useful in the case that you do not want the IP addresses of any other local interfaces to be the
