sntp client mode This command enables the Simple Network Time Protocol (SNTP) client, and optionally sets the mode to either broadcast or unicast. Syntax sntp client mode [broadcast | unicast] Use the no sntp client mode command to disable SNTP client mode. Parameters broadcast unicast SNTP operates in the same manner as multicast mode but uses a local broadcast address instead of a multicast address. The broadcast address has a single subnet scope while a multicast address has Internet-wide scope. SNTP operates in a point-to-point fashion. A unicast client sends a request to a designated server at its unicast address and expects a reply from which it can determine the time and, optionally, the round-trip delay and local clock offset relative to the server. Default Disabled (No SNTP requests are sent from the client, nor are any received SNTP messages processed.) Mode Global Config sntp client port This command sets the SNTP client port ID to a value from 1-65535. Syntax sntp client port portid [poll-interval] Parameters portid poll-interval Specify the local UDP port to listen for responses/broadcasts. The allowed range is (1 to 65535). Default value is 123. Optionally, set the poll interval for the client in seconds, as a power of two, in the range from 6 to 10. Default value is 6. This setting is true for both unicast and broadcast poll requests. Broadcasts received prior to the expiry of this interval are discarded. Use the no sntp client port command to reset the SNTP client port to its default values. Default 123 Usage You can also set the poll interval for a unicast client with the sntp unicast client poll-interval command. Mode Global Config sntp unicast client poll-interval This command sets the poll interval for SNTP unicast clients in seconds as a power of two where poll-interval can be a value from 6 to 16. Syntax sntp unicast client poll-interval poll-interval Use the no sntp unicast client poll-interval command to reset the poll interval for SNTP unicast clients to its default. Time Commands | 245

sntp client mode

This command enables the Simple Network Time Protocol (SNTP) client, and optionally sets the mode

to either broadcast or unicast.

Syntax

sntp client mode [broadcast | unicast]

Use the

no sntp client mode

command to disable SNTP client mode.

Parameters

Default

Disabled (No SNTP requests are sent from the client, nor are any received SNTP messages processed.)

Mode

Global Config

sntp client port

This command sets the SNTP client port ID to a value from 1–65535.

Syntax

sntp client port

portid

[

poll-interval

]

Parameters

Use the

no sntp client port

command to reset the SNTP client port to its default values.

Default

123

Usage

You can also set the poll interval for a unicast client with the

sntp unicast client poll-interval

command.

Mode

Global Config

sntp unicast client poll-interval

This command sets the poll interval for SNTP unicast clients in seconds as a power of two where

poll-interval

can be a value from 6 to 16.

Syntax

sntp unicast client poll-interval

poll-interval

Use the

sntp unicast client poll-interval

command to reset the poll interval for SNTP unicast

clients to its default.

broadcast

SNTP operates in the same manner as multicast mode but uses a local broadcast address

instead of a multicast address. The broadcast address has a single subnet scope while a

multicast address has Internet-wide scope.

unicast

SNTP operates in a point-to-point fashion. A unicast client sends a request to a designated

server at its unicast address and expects a reply from which it can determine the time and,

optionally, the round-trip delay and local clock offset relative to the server.

portid

Specify the local UDP port to listen for responses/broadcasts. The allowed range is (1 to

65535). Default value is 123.

poll-interval

Optionally, set the poll interval for the client in seconds, as a power of two, in the range

from 6 to 10. Default value is 6. This setting is true for both unicast and broadcast poll

requests. Broadcasts received prior to the expiry of this interval are discarded.
