Configuring System Time
In Process
- —Occurs when the SNTP server does not fully trust its own time server (i.e. when first
booting up the SNTP server).
• 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.

STEP 4
STEP 5
• 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 internet and
NOTE
configured with a DNS server or configured so that a DNS server is identified by using DHCP. (See
DNS Settings)
• IP Version—Select the version of the IP address: Version 6 or Version 4.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The options are
- Link Local—The IPv6 address uniquely identifies hosts on a single network link. A link local
address has a prefix of FE80, is not routable, and can be used for communication only on the local
network. Only one link local address is supported. If a link local address exists on the interface, this
entry replaces the address in the configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other
networks.
• Link Local Interface—Select the link local interface (if IPv6 Address Type Link Local is selected) from
the list.
• SNTP Server IP Address—Enter the SNTP server IP address. The format depends on which address
type was selected.
• SNTP Server—Select the name of the SNTP server from a list of well-known NTP servers. If other is
chosen, enter the name of an SNTP server in the adjacent field.
