Switch Services 5 - 27
5.3.3 Defining a NTP Neighbor Configuration
The switch’s NTP association can be either a neighboring peer (the switch synchronizes to another associated device) or
a neighboring server (the switch synchronizes to a dedicated SNTP server resource). Refer to the
NTP Neighbor tab to
assess the switch’s existing configurations (both peer and server) and, if necessary, modify the attributes of an existing
peer or server configuration or create a new neighbor peer or server SNTP configuration.
To review the switch’s existing NTP neighbor configurations:
1. Select Services > Secure NTP from the main menu tree.
2. Select the NTP Neighbor tab.
3. Refer to the following information (as displayed within the NTP Neighbor tab) to assess whether an existing neighbor
configuration can be used as is, if an existing configuration requires modification or a new configuration is required.
4. Select an existing neighbor and click the Edit button to modify the existing peer or server designation, IP address,
version, authentication key ID and preferred source designation.
5. Select an existing entry and click the Delete button to remove it from the table.
IP Address/
Hostname Displays the numeric IP address of the resource (peer or server) providing switch SNTP resources.
Ensure the server is on the same subnet as the switch 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 NTP 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 four implementations of NTP are
available. The latest version is NTPv4, but the official Internet standard is NTPv3.
