System management commands allow you to configure basic system management functions such as the system name, the router’s location and coordinates, and Common Language Location Identifier (CLLI) code as well as time zones, Network Time Protocol (NTP), Simple Network Time Protocol (SNTP) properties, CRON and synchronization properties.
On SR OS routers, it is possible to query the DNS server for IPv6 addresses. By default, the DNS names are queried for A-records only (address-preference is IPv4-only). If the address-preference is set to IPv6 first, the DNS server is queried for AAAA-records first, and if there is no successful reply, then A-records.
