System Time Configuring System Time 6 • 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 switch. - 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. STEP 2 To add a Unicast SNTP server, enable SNTP Client Unicast. STEP 3 Click Add to display the Add SNTP Server page. 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 switch 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 the Defining DNS Servers section.) • 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. Cisco Small Business 200 Series Smart Switch Administration Guide 58

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 switch 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 the
Defining DNS Servers
section.)
•
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.
