extEthernetInterfaceDHCPv6PrimaryDNSServer
Module: CME-MIB
OID (symbolic): CME-MIB::extEthernetInterfaceDHCPv6PrimaryDNSServer
OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.4.5.3.2.5
Node type: OBJECT-TYPE
Type: InetAddressIPv6
Access: read-only
Description: The primary DNS server, assigned by the DHCPv6 server.
NOTE: If extEthernetInterfaceIPv6Enabled or extEthernetInterfaceDHCPv6Enabled is disabled or if DHCPv6 server is not available, this object has the value '0:0:0:0:0:0:0:0'.
What is extEthernetInterfaceDHCPv6PrimaryDNSServer?
This read-only object reports the primary DNS server address assigned to the ethernet interface by a DHCPv6 server, reading as all zeros if IPv6 or DHCPv6 is disabled or unavailable. An administrator checks this to confirm the management module has a working primary IPv6 DNS server. For example, an admin finds this primary DNS server address unreachable and traces an IPv6 name-resolution failure back to that DHCPv6-assigned server.
