SNTP in unicast mode

Like broadcast mode, configuring SNTP for unicast mode enables SNTP. However, for unicast

operation, 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

timesync sntp

Selects SNTP as the time synchronization method.

Syntax

sntp unicast

Configures the SNTP mode for unicast operation.

Syntax

[no] sntp server priority [ 1-3 ] ip-address [ oobm ] [ version ]

Use the no version of the command to disable SNTP.

priority Specifies the order in which the configured SNTP servers are polled for the time.

ip-address An IPv4 or IPv6 address of an SNTP server.

oobm For switches that have a separate out-of-band management port, specifies that

SNTP traffic goes through that port. (By default, SNTP traffic goes through the

data ports.)

version The protocol version of the SNTP server. Allowable values are 1 through 7; default

is 3.

Syntax

no sntp server <ip-addr>

Deletes the specified SNTP server.

NOTE: Deleting an SNTP server when only one is configured disables SNTP unicast operation.

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):

HP Switch(config)# timesync sntp

Selects SNTP.
