Description: Cisco UCS vnic:IpV4PooledAddr:secDns managed object property
What is cucsVnicIpV4PooledAddrSecDns?
This OID reports the secondary DNS server address configured on an IPv4 address drawn from an IP address pool and assigned to a vNIC (IpV4PooledAddr), used as a fallback if the primary DNS server doesn't respond. An admin cares because relying on a single DNS server is a common single point of failure, and this secondary entry is what keeps name resolution working if the primary goes down. For example, after a DNS server outage caused intermittent iSCSI boot failures, an admin would check whether this secDns value was even populated as a fallback.
Examples
Walk all instances (SNMPv2c):
