• Poll Interval—Displays whether polling is enabled or disabled.
• Authentication Key ID—Key Identification used to communicate between the SNTP
server and device.
• Stratum Level—Distance from the reference clock expressed as a numerical value. An
SNTP server cannot be the primary server (stratum level 1) unless polling interval is
enabled.
• Status—SNTP server status. The possible values are:
- Up—SNTP server is currently operating normally.
- Down—SNTP server is currently not available.
- Unknown—SNTP server status is unknown.
- In Process—Connection to SNTP server currently in process.
• Last Response—Last date and time a response was received from this SNTP server.
• Offset—Estimated offset of the server's clock relative to the local clock, in
milliseconds. The host determines the value of this offset using the algorithm described
in RFC 2030.
• Delay—Estimated round-trip delay of the server's clock relative to the local clock over
the network path between them, in milliseconds. The host determines the value of this
delay using the algorithm described in RFC 2030.
• Source—How the SNTP server was defined, for example: manually or from DHCPv6
server.
• Interface—Interface on which packets are received.
To add a Unicast SNTP server, enable SNTP Client Unicast.
Click Add.
To remove all user-defined SNTP servers, click Restore Default Servers.
NOTE
Enter the following parameters:
• Server Definition—Select if the SNTP server is going to be identified by its IP address
or if you are going to select a well-known SNTP server by name from the list.
To specify a well-known SNTP server, the device must be connected to the
NOTE
internet and configured with a DNS server or configured so that a DNS server is
identified by using DHCP. (See
• IP Version—Select the version of the IP address: Version 6 or Version 4.
