•
IPv4 Source Interface—Select the IPv4 interface whose IPv4 address will
be used as the source IPv4 address in messages used for communication
with the SNTP server.
•
IPv6 Source Interface—Select the IPv6 interface whose IPv6 address will
be used as the source IPv6 address in messages used for communication
with the SNTP server.
If the Auto option is selected, the system takes the source IP address
NOTE
from the IP address defined on the outgoing interface.
This page displays the following information for each Unicast SNTP server:
•
SNTP Server—SNTP server IP address. The preferred server, or hostname,
is chosen according to its stratum level.
•
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 is currently being searched for by the device.
In Process
-
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.
