Port MIB Counters (14 Blocks), Offset (start): 0x600, 0xA00, 0xE00, 0x1200
The CPU must read all of the MIB counters during initialization in order to reset the counters to ‘0’. All counters are
32-bits. The CPU must access the counters using single datum transactions (burst reads/writes are not allowed).

FilBroad
Filter Broadcast.
0 - Broadcast packets are forwarded to all ports.
1 - The the GT-482xx discards Broadcast packets.
Note: For exact description see "Address Recognition"
0x0
11
ForwUnk
Enable Forwarding Unknown Unicast DA Packets to this
transmit port.
0 - Unknown packets are forwarded.
1 - the GT-482xx does not forward Unknown packets to
this port.
Note: For exact description see "Address Recognition"
0x0
12
SpanEn
Spanning Tree Enable.
Meaningful only when SpanEn bit in the Global Control
register is set.
0 - All packets are accepted.
1 - The the GT-482xx discards all incoming/outgoing
packets except for BPDU packets.
0x0
13
VTagEn
Virtual LAN Tagging Packet Extension Enable
0 - Accept packets up to 1518 bytes in length
1 - Accept packets up to 1536 bytes in length
DAddr[8] at reset
14
ForcePri
Force Priority.
0 - Priority is set base on the Pd, Ps, Pri bit in the port
control register or the 802.1Q quality of service feild.
1 - Priority is set based on Pri bit in the port control reg-
ister
0x0

SA[0:3]
Source Address - The least significant bits of the source
address for all ports. This address is being used for
Flow Control.
