HP Switch(config)# sntp unicast

Activates SNTP in unicast mode.

HP Switch(config)# sntp server priority 1

10.28.227.141

Specifies the SNTP server and accepts the current SNTP server version (default: 3.)

Figure 16 Configuring SNTP for unicast operation

If the SNTP server you specify uses SNTP v4 or later, use the sntp server command to specify

the correct version number. For example, suppose you learned that SNTP v4 was in use on the

server you specified above (IP address 10.28.227.141.) You would use the following commands

to delete the server IP address , re-enter it with the correct version number for that server

SNTP unicast time polling with multiple SNTP servers

When running SNTP unicast time polling as the time synchronization method, the switch requests

a time update from the server you configured with either the server address parameter in the menu

interface, or the primary server in a list of up to three SNTP servers configured using the CLI. If the

switch does not receive a response from the primary server after three consecutive polling intervals,

the switch tries the next server (if any) in the list. If the switch tries all servers in the list without

success, it sends an error message to the Event Log and reschedules to try the address list again

after the configured Poll Interval time has expired.

Changing the SNTP poll interval

Syntax

sntp <30..720>

Specifies the amount of time between updates of the system clock via SNTP. The default is 720

seconds and the range is 30 to 720 seconds. (This parameter is separate from the poll interval

parameter used for Timep operation.)

Example

To change the poll interval to 300 seconds:
