This object specifies the interface type(s) for which the PSDev Access Control Table access rules are enabled. If a bit field is set to 1, the PS MUST only forward traffic received through that interface type if the source physical address is an entry in the cabhPsDevAccessControlTable. If a bit field is set to 1, the PS MUST only forward traffic destined to a device on that interface type if the destination physical address is an entry in the cabhPsDevAccessControlTable. If the bit field for an interface type is not set, i.e., if it is equal to 0, the PS MUST NOT apply forwarding restrictions for that interface type based on the Access Control Table. The PS MUST implement cabhPsDevAccessControlEnable for bit 1 (wireless LAN) and for bit 3 (HomePlug). If the PS does not implement cabhPsDevAccessControlEnable for any of the other defined bits, the PS MUST return inconsistent value error, and not allow the bit to be set, if an attempt is made to set a bit that is not implemented. If the PS implements a HomePNA interface and implements the PSDev Access Control Table enable functionality for the HomePNA interface, then if bit 0 is set, the PS MUST apply PSDev Access Control Table access rules to any PS interface of IANAifType 220 (Home Phoneline Networking Alliance). If the PS does not implement PSDev Access Control Table enable functionality for the HomePNA interface, and an attempt is made to set bit 0 to value '1', the PS MUST return 'Inconsistent Value' error and MUST NOT set bit 0 to value '1'. If bit 1 (ieee80211) is set, the PS MUST apply PSDev Access Control Table access rules to any PS interface of IANAifType 71 (radio spread spectrum). If the PS implements an IEEE 802.3/CSMA-CD interface and implements the PSDev Access Control Table enable functionality for the IEEE 802.3/CSMA-CD interface, then if bit 2 is set, the PS MUST apply PSDev Access Control Table access rules to any PS interface of IANAifType 6 (ethernetCsmacd). If the PS does not implement PSDev Access Control Table enable functionality for a IEEE 802.3/CSMA-CD interface, and an attempt is made to set bit 2 to value '1', the PS MUST return 'Inconsistent Value' error and MUST NOT set bit 2 to value '1'. If bit 3 (homeplug) is set, the PS MUST apply PSDev Access Control Table access rules to any PS HomePlug Powerline Alliance (HomePlug) interface as defined by HomePlug Powerline Alliance (www.homeplug.org). If the PS implements a USB interface and implements the PSDev Access Control Table enable functionality for the USB interface, then if bit 4 is set, the PS MUST apply PSDev Access Control Table access rules to any PS interface of IANAifType 160 (USB). If the PS does not implement PSDev Access Control Table enable functionality for the USB interface, and an attempt is made to set bit 4 to value '1', the PS MUST return 'Inconsistent Value' error and MUST NOT set bit 4 to value '1'. If the PS implements an IEEE 1394 interface and implements the PSDev Access Control Table enable functionality for the IEEE 1394 interface, then if bit 5 is set, the PS MUST apply PSDev Access Control Table access rules to any PS interface of IANAifType 144 (IEEE1394 High Performance Serial Bus). If the PS does not implement PSDev Access Control Table enable functionality for the IEEE 1394 interface, and an attempt is made to set bit 5 to value '1', the PS MUST return 'Inconsistent Value' error and MUST NOT set bit 5 to value '1'. If the PS implements a SCSI interface and implements the PSDev Access Control Table enable functionality for the SCSI interface, then if bit 6 is set, the PS MUST apply PSDev Access Control Table access rules to any PS SCSI-2 or SCSI-3 interface. If the PS does not implement PSDev Access Control Table enable functionality for the SCSI interface, and an attempt is made to set bit 6 to value '1', the PS MUST return 'Inconsistent Value' error and MUST NOT set bit 6 to value '1'. If bit 7 (other) is set, the PS MAY apply PSDev Access Control Table filter access to any PS interface of a type other than the types defined by bits 0 � 6.
