In an AOS-CX Virtual Switching Extension (VSX) environment, the Configuration Synchronization (vsx-sync) feature simplifies management by allowing the Primary switch to automatically push configuration settings to the Secondary switch.
Primary-Only Configuration: A fundamental rule of vsx-sync is that all synchronization commands must be configured on the Primary VSX node. The Secondary node simply receives and applies the configuration; it does not initiate the sync.
The time Synchronization Module: In AOS-CX, the command used to synchronize all time-related parameters—including NTP servers, authentication keys, and time zone settings—is vsx-sync time.
Command Logic: By adding vsx-sync time under the vsx context on the Primary switch, the NTP configuration currently present on the Primary will be replicated to the Secondary switch ' s running configuration.
Why other options are incorrect:
Options B and C: These are incorrect because they suggest configuring the sync on the Secondary switch.
Option A: While it specifies the Primary switch, vsx-sync ntp is not the correct command syntax in AOS-CX; the feature is consolidated under the broader vsx-sync time module.
