This OID reports the CDN value actually applied and visible to the operating system for the launched, deployed instance of an iSCSI vNIC as it actually runs on a server, as opposed to the vNIC's policy-level definition (IScsiLCP), which should match the administratively configured name if everything applied correctly. An admin cares because if this operational CDN name doesn't match what was configured, OS-level scripts expecting a specific interface name will fail to find the iSCSI NIC. For example, an admin debugging a boot script that can't find 'eth-iscsi0' would check this operCdnName to confirm the OS actually received that name rather than a default one.
