Configuring (Enabling or Disabling) the SNTP Mode

Enabling the SNTP mode means to configure it for either broadcast or unicast mode. Remember that 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).

Syntax: timesync sntp

Selects SNTP as the time protocol.

sntp < broadcast unicast >

Enables the SNTP mode (below and page 9-12).

Syntax: sntp server priority < 1 - 3 > < ip-addr ipv6-addr> [1-7 ]

Required only for unicast mode page 9-12). Provides SNTP server address, priority, and (optionally) the server version. The priority setting specifies the order in which the configured servers are polled for getting the time. The server version range is 1-7 and the default is 3.(page 9-12ff.).

Note: For more information about IPv6 addresses, refer to the IPv6 Configuration Guide for your switch.

Syntax: sntp < 30 - 720 >

Enabling the SNTP mode also enables the SNTP poll interval (default: 720 seconds; page 9-14).
