detected through a broadcast. The default value between each polling request is 720 seconds,

but can be configured. At least one manually configured server IP address is required.

About TimeP time synchronization

You can either manually assign the switch to use a TimeP server or use DHCP to assign the TimeP

server. In either case, the switch can get its time synchronization updates from only one, designated

TimeP server. This option enhances security by specifying which time server to use.

Selecting a time synchronization protocol

timesync command

• Term: sntp

Enabling and disabling time synchronization protocols

Enabling SNTP

This section describes steps and syntax for enabling the Simple Network Time Protocol (SNTP).

IMPORTANT: Enabling SNTP means configuring the [ broadcast | unicast ] switch.

SNTP mode is disabled by default. Unless it is enabled, SNTP does not operate even if specified

by the CLI timesync command or by the menu interface Time Sync Method parameter. In

order to run SNTP as the switch's time synchronization protocol, you must also select SNTP as the

time synchronization method by using the CLI timesync command, or the menu interface Time

Sync Method parameter.

NOTE: At least one key-id must be configured as trusted, and it must be associated with

one of the SNTP servers . To edit or remove the associated key-id information or SNTP server

information, SNTP authentication must be disabled.
