Access: read-write

Description: This object refers to which mac address is being used: the default or locally administered address. The value of useLocallyAdministeredAddress(2) is read-only. Setting this object with useDefaultPhyAddress(1) will have the effect of deleting the locally administered address. It cannot be restored.

What is cnIfExtnPhyAddressDefault?

This read-write setting selects whether the interface uses its factory default MAC address or a locally administered one; setting it to the default option removes any locally administered address.
