extEthernetInterfaceDHCPv6SecondaryDNSServer
Module: CME-MIB
OID (symbolic): CME-MIB::extEthernetInterfaceDHCPv6SecondaryDNSServer
OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.4.5.3.2.6
Node type: OBJECT-TYPE
Type: InetAddressIPv6
Access: read-only
Description: The secondary 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 extEthernetInterfaceDHCPv6SecondaryDNSServer?
This read-only object reports the secondary 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 as the fallback IPv6 DNS server the management module would use if the primary server fails to respond. For example, an admin confirms this secondary DNS server address is populated to provide IPv6 name-resolution resilience.
