Description: The Secondary DNS server IP address to be assigned to the client. To delete a configured Secondary DNS server IP, please set hh3cDHCPSrvGlbPoolSecondaryDNSIP to 0. It takes effect only when hh3cDHCPSrvGlobalPoolNetwork is set.
What is hh3cDHCPSrvGlbPoolSecondaryDNSIP?
Sets the secondary (backup) DNS server IP address assigned to clients from this pool, taking effect only once hh3cDHCPSrvGlobalPoolNetwork is set; setting it to 0 removes the configured secondary DNS server. An admin configures this as a fallback resolver for clients if the primary DNS server is unavailable.
