=== NTP Server Mode
|
|
|
|
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/ntp/server_mode_server]
|

|
|
==== Description
|
|
|
|
Verify NTP server operating in server mode, syncing from upstream while
|
|
serving clients.
|
|
|
|
This test validates server mode where devices synchronize from upstream
|
|
NTP servers while simultaneously serving time to downstream clients. It
|
|
creates a two-tier hierarchy:
|
|
|
|
- Upstream: NTP server with local reference clock (stratum 8)
|
|
- Downstream: NTP server that syncs from upstream and serves to clients (stratum 9)
|
|
|
|
The test verifies both servers operate correctly and serve accurate time.

==== Sequence
|
|
|
|
. Set up topology and attach to devices
|
|
. Configure upstream NTP server with local reference clock
|
|
. Configure downstream NTP server syncing from upstream
|
|
. Verify network connectivity with upstream NTP server
|
|
. Query time from upstream NTP server
|
|
. Verify upstream NTP server statistics
|
|
. Verify network connectivity with downstream NTP server
|
|
. Wait for downstream to sync from upstream
|
|
. Verify downstream NTP server statistics
