SNTP Client Configuration 191
timestamp in the request is set to the time of day according to the client clock in NTP timestamp
format. This allows a simple calculation to determine the propagation delay between the server and
client and to align the local clock generally within a few tens of milliseconds relative to the server. In
addition, this provides a simple method to verify that the server reply is in fact a legitimate response
to the specific client request and to avoid replays.
In multicast mode, the client has no information available to calculate the propagation delay or to
determine the validity of the server unless the NTP authentication scheme is used.
Procedure
To enable or disable the compensation for local clock offset
Mode
Configure
Command Purpose
Step 1
node (cfg)#[no] sntp-client local-clock-
offset
Enables the SNTP client’s
compensation for local clock offset.
Using the no command syntax disables
this feature.
Example: Enabling the SNTP Client Compensation for Local Clock Offset
SN(cfg)# sntp-client local-clock-offset
Example: Disabling the SNTP Client Compensation for Local Clock Offset
SN(cfg)#
no sntp-client local-clock-offset
21.11 Enabling and Disabling Root Delay Compensation
The root delay indicates the total roundtrip delay to the primary reference source. Enabling the
compensation for root delay defines to compensate any server time difference to the SNTP root
server (stratum 1).
Procedure
To enable or disable the compensation for root delay
Mode
Configure
Command Purpose
Step 1 node (cfg)#[no] sntp-client root-delay-
compensation
Enables the SNTP client’s
compensation for root delay. Using the
no command syntax disables this
feature.
Example: Enabling the SNTP Client Root Delay Compensation
SN(cfg)# sntp-client root-delay-compensation
Example: Disabling the SNTP Client Root Delay Compensation
SN(cfg)# no sntp-client root-delay-compensation
