Queries are first sent to the primary server. If the primary server does not respond within 1 second, or if it is not synchronized, the switch queries the second server. If the switch cannot obtain the time, it restarts the query process. Otherwise, the switch waits for the sntp-client update interval before querying again.
The following example configures a primary NTP server:
configure sntp-client primary 10.1.2.2
The following example configures the primary NTP server to use the management virtual router VR-Mgmt:
configure sntp-client primary 10.1.2.2 vr VR-Mgmt
This command was first available in ExtremeXOS 10.1.
The vr vr_name option was added in ExtremeXOS 11.0.
This command is available on ExtremeSwitching 5420, 5520, 5720 series switches.
