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 9-12 ff.).
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).
