IP Address/
Hostname Displays the numeric IP address of the resource (peer or server) providing SNTP resources for
the switch. Ensure the server is on the same subnet as the switch in order to provide SNTP
support.
Neighbor Type Displays whether the NTP resource is a Peer (another associated peer device capable of
SNTP support) or a Server (a dedicated SNTP server resource). This designation is made
when adding or editing an NTP neighbor.
Key ID Displays whether AutoKey Authentication or Symmetric Key Authentication is used to secure
the interaction between the switch and its NTP resource. This designation is made when
adding or editing an NTP neighbor.
Preferred Source Displays whether this NTP resource is a preferred NTP resource. Preferred sources (those
with a checkmark) are contacted before non-preferred resources. There can be more than
one preferred source.
NTP Version Displays a NTP version between 1 and 4. Currently version three and version four
implementations of NTP are available. The latest version is NTPv4, but the official Internet
standard is NTPv3.
