This read-create field holds the MAC address used to identify the ENode or remote-FCF associated with this static VFC, applicable when hh3cFCoEStaticVfcBindType is set to macAddress; a FIP frame is matched to this VFC only if its source MAC equals this value. An admin sets this when the peer is reachable across a Layer-2 Ethernet network rather than directly attached, so FIP frames can still be correctly associated with the intended VFC. For example, binding this to a server's converged network adapter MAC address ensures that ENode's FIP FLOGI is matched to this specific VFC even though it traverses intermediate switches.
