SPWS028B – APRIL 1997 – REVISED SEPTEMBER 1997

POST OFFICE BOX 655303

add address VLAN tag register, addVLANID at 0x2D (DIO), byte 1

BIT

Reserved

ADDVLANID

Initial Values After Reset

The addVLANID register is used with the addnode and addport registers to add/edit a node’s VLAN assignment.

This register is a read/write register. When the ADD logic is operating, this register is locked and no writes can

be made to it.

add address register, addnode at 0x38–0x3D (DIO)

The addnode register is a read/write register. When the ADD logic is operating, this register is locked and no

writes can be made to it. The unicast or multicast address in this register (written in Ethernet native data format)

is added to the lookup table when the ADD bit in the adddelcontrol register is set to 1. The default value of this

add routing code register, addport at 0x3E–0x3F (DIO)

The addport register is used to change port and flag assignments for the node address contained in the addnode

is a unicast or multicast address.

This register is a read/write register. When the ADD logic is operating, this register is locked and no writes can

be made to it.

This interface is used to enter broadcast/multicast addresses to the TNETX15VE table. Wire ADDs operate on

packet-source addresses, and these are all defined by IEEE to be unicast addresses. Therefore, bit 47 of the

address is stored as 0.
