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.

As with broadcast mode, configuring SNTP for unicast mode enables SNTP. For unicast operation,

however, you must also specify the IP address of at least one SNTP server. The switch allows up

to three unicast servers. You can use the Menu interface or the CLI to configure one server or to

replace an existing unicast server with another. To add a second or third server, you must use the

CLI.

Syntax

sntp unicast

Configures the SNTP mode for unicast operation.

Syntax

sntp server <ip-addr>

Required only for unicast mode.

Example

To select SNTP and configure it with unicast mode and an SNTP server at

10.28.227.141 with the default server version (3) and default poll interval (720

seconds):

• Selects SNTP:

(HP_Switch_name#) timesync sntp

• Activates SNTP in unicast mode:

(HP_Switch_name#) sntp unicast

• Specifies the SNTP server and accepts the current SNTP server version [default:

3.]:

(HP_Switch_name#) sntp server priority 1

10.28.227.141

Figure 2 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 SNTP v4 is 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
