Managing the Switch
6 You can verify the configuration using the following commands:
— show sntp-client
This command provides configuration and statistics associated with SNTP and its connectivity to
the NTP server.
— show switch {detail}
This command indicates the GMT offset, the Daylight Savings Time configuration and status, and
the current local time.
NTP updates are distributed using GMT time. To properly display the local time in logs and other
time-stamp information, the switch should be configured with the appropriate offset to GMT based on
geographical location. Table 13 lists GMT offsets.
