•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
level1) 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 is currently being searched for by the device.
-
In Process—Occurs when the SNTP server has not fully trusted its own
time server (i.e. when first booting up the SNTP server).
•Last Response—Date and time of the last time a response was received
from this SNTP server.
•Offset—The 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—The 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 SNTP server was defined, for example: manually or from
DHCPv6 server.
•Interface—Interface on which packets are received.
STEP 2 To add a Unicast SNTP server, enable SNTP Client Unicast.
STEP 3 Click Add.
STEP 4 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.
NOTE To specify a well-known SNTP server, the device must be connected
to the Internet and configured with a DNS server or configured so that a DNS
server is identified by using DHCP. (See DNS Settings)
