Configuring SNTP

The SNTP/Clock screen contains the parameters for configuring Simple Network Time Protocol (SNTP).

To open the SNTP/Clock screen:


Step Action

1

From the Edit menu, choose SNTP/Clock. The SNTP_clock dialog box appears with the Simple Network Time Protocol tab.

2

Edit the fields as indicated by the table.

The following table describes the Simple Network Time Protocol fields.

Field Description
PrimaryServerInet
AddressType
The IP address type (IPv4 or IPv6) of the primary SNTP server.
PrimaryServerInet
Address
The IP address of the primary SNTP server.
SecondaryServerInet
AddressType
The IP address type (IPv4 or IPv6) of the secondary SNTP server.
SecondaryServerInet
Address
The IP address of the secondary SNTP server.
State

Controls whether the device uses the Simple Network Time Protocol to synchronize the device clock to the Coordinated Universal Time. If the value is disabled, the device does not synchronize its clock using SNTP.

If the value is unicast, the device synchronizes shortly after boot time when network access becomes available, and periodically thereafter.

SynchInterval Controls the frequency, in hours, with which the device attempts to synchronize with the NTP servers.
ManualSynch Request Specifies that the device must immediately attempt to synchronize with the NTP servers.
LastSynch
Time
Specifies the UTC when the device last synchronized with an NTP server.
LastSyncSourceInet
AddressType
Specifies the IP source address type (IPv4 or IPv6) of the NTP server with which this device last synchronized.
LastSyncSourceInet
Address
Specifies the IP source address of the NTP server with which this device last synchronized.
NextSynch
Time
Specifies the UTC at which the next synchronization is scheduled.
PrimaryServer SynchFailures Specifies the number of times the switch failed to synchronize with the primary server address. However, synchronization with the secondary server address can still occur.
SecondaryServer SynchFailures Specifies the number of times the switch failed to synchronize with the secondary server address.
CurrentTime Specifies the UTC for the switch.
