COMMAND LINE INTERFACE

Command Usage

This command specifies time servers from which the switch will poll for time updates when set to SNTP client mode. The client will poll the time servers in the order specified until a response is received. It issues time synchronization requests based on the interval set via the sntp poll command.

Example

Console(config)#sntp server 10.1.0.19

Console(config)#

Related Commands
