Configuring SNTP

SNTP is a simplified, client-only version of NTP specified in RFC 4330. SNTP supports only the
client/server mode. An SNTP-enabled device can receive time from NTP servers, but cannot provide time
services to other devices.
SNTP uses the same packet format and packet exchange procedure as NTP, but provides faster
synchronization at the price of time accuracy.
If you specify multiple NTP servers for an SNTP client, the server with the best stratum is selected. If
multiple servers are at the same stratum, the NTP server whose time packet is first received is selected.

Configuration restrictions and guidelines

When you configure SNTP, follow these restrictions and guidelines:
You cannot configure both NTP and SNTP on the same device.
•
Make sure you use the clock protocol command to specify the time protocol as NTP on an MDC.
•
You can configure SNTP only on one MDC.
•
