Selecting SNTP time servers
This procedure describes how to select a primary and secondary SNTP time server
Mode: Configure
Example:
Selecting SNTP time servers
In the following example an internal SNTP time server (172.16.1.10) is selected as primary and utcnist.colo-
rado.edu (128.138.140.44) as secondary SNTP time server.
node(cfg)#sntp-client server primary 172.16.1.10
node(cfg)#sntp-client server secondary 128.138.140.44
Defining SNTP client operating mode
A SNTP client can operate in multicast mode, unicast mode or anycast mode:
•
In unicast mode (point to point), the client sends a request to a designated server at its unicast address and
expects a reply from which it can determine the time and, optionally, the roundtrip delay and local clock
offset relative to the server.
•
In anycast mode (multipoint to point), the client sends a request to a designated local broadcast or multicast
group address and expects a reply from one or more anycast servers.
•
In multicast mode (point to multipoint), the client sends no request and waits for a broadcast from a desig-
nated multicast server.
Note
Unicast mode is the default SNTP client operating mode.
This procedure describes how to configure the SNTP client operating mode
Mode: Configure
Note
When selecting the anycast operating-mode you have to define the IP
address where the anycast request is sent. Refer to section
“Defining the
SNTP client anycast address”
on page 240 for more details.
