Add an NTPv3 Server

Add a remote NTP server to the configuration by specifying its IP address. NTP adds this IP address to a list of servers, which the local NTP client uses to query remote time servers for time information. The list of qualified servers called to is a peer list.

Note

Server Field Descriptions

Use the data in the following table to use the Server tab.

Name

Description

ServerAddressType

Specifies the IP address of the remote NTP server.

Enable

Activates or disables the remote NTP server. The default is enabled.

Authentication

Activates or disables MD5 or SHA1 authentication on this NTP server. MD5 or SHA1 produces a message digest of the key. MD5 or SHA1 verifies the integrity of the communication, authenticates the origin, and checks for timeliness.

The default is no authentication.

KeyId

Specifies the key ID used to generate the MD5 or SHA1 digest for this NTP server. The default is 0, which indicates that authentication is disabled.

AccessAttempts

Specifies the number of NTP requests sent to this NTP server.

Success

Specifies the number of times this NTP server updated the time.

Failure

Specifies the number of times the client rejected this NTP server while it attempted to update the time.

Stratum

This variable is the stratum of the server.

Version

This variable is the NTP version of the server.

RootDelay

This variable is the root delay of the server.

Precision

This variable is the NTP precision of the server in seconds.

Reachable

This variable is the NTP reachability of the server.

Synchronized

This variable is the status of synchronization with the server.

SourceIpAddr

Note:

Exception: only supported on VSP 8600 Series.

Specifies the source IP for the server. If you do not configure a source IP, by default, the entry is initialized to 0.0.0.0. The IP address specified can be any local interface.
