What is standbyDhcpPrimaryDNSServer?
This read-only object reports the primary DNS server address assigned to the standby management module by the DHCP server, applicable only to chassis with an installed standby MM. An administrator checks this to confirm the standby MM has a working primary DNS server for name resolution. For example, an admin finds this primary DNS server address unreachable and traces a standby MM name-resolution failure back to that DHCP-assigned server.
