Revision 1.6
Register 3 (0x03): Global Control 1
Bit
Name
R/W
Description
Default
7
Pass All Frames
R/W
=1, Switch all packets including bad ones. Used solely for debugging
purposes. Works in conjunction with sniffer mode only.
0
6
Port 3 Tail Tag
Mode Enable
R/W
=1, Enable port 3 tail tag mode.
=0, Disable.
0
5
IEEE 802.3x Transmit
Direction Flow
Control Enable
R/W
=1, Will enable transmit direction flow control feature.
=0, Will not enable transmit direction flow control feature. Switch will not
generate any flow control (PAUSE) frame.
1
4
IEEE 802.3x Receive
Direction Flow
Control Enable
R/W
=1, Will enable receive direction flow control feature.
=0, Will not enable receive direction flow control feature. Switch will not react
to any flow control (PAUSE) frame it receives.
1
3
Frame Length
Field Check
R/W
=1, Will check frame length field in the IEEE packets. If the actual length
does not match, the packet will be dropped (for Length/Type field < 1500).
=0, Not check
0
2
Aging Enable
R/W
=1, Enable age function in the chip
=0, Disable age function in the chip
1
Fast Age Enable
R/W
=1, Turn on fast age (800us)
0
Aggressive
Back-Off Enable
R/W
=1, Enable more aggressive back off algorithm in half duplex mode to
enhance performance. This is not an IEEE standard.
0
Register 4 (0x04): Global Control 2
Bit
Name
R/W
Description
Default
7
Unicast
Port-VLAN
Mismatch Discard
R/W
This feature is used with port-VLAN (described in reg. 17, reg. 33, …)
=1, All packets can not cross VLAN boundary
=0, Unicast packets (excluding unkown/multicast/ broadcast) can cross VLAN
boundary
Note: Port mirroring is not supported if this bit is set to “0”.
1
6
Multicast Storm
Protection Disable
R/W
=1, “Broadcast Storm Protection” does not include multicast packets. Only DA =
FF-FF-FF-FF-FF-FF packets will be regulated.
=0, “Broadcast Storm Protection” includes
DA = FF-FF-FF-FF-FF-FF and
DA[40] = 1 packets.
1
5
Back Pressure
Mode
R/W
=1, Carrier sense based backpressure is selected
=0, Collision based backpressure is selected
1
4
Flow Control and
Back Pressure Fair
Mode
R/W
=1, Fair mode is selected. In this mode, if a flow control port and a non-flow
control port talk to the same destination port, packets from the non-flow control
port may be dropped. This is to prevent the flow control port from being flow
controlled for an extended period of time.
=0, In this mode, if a flow control port and a non-flow control port talk to the same
destination port, the flow control port will be flow controlled. This may not be “fair”
to the flow control port.
1
3
No Excessive
Collision Drop
R/W
=1, The switch will not drop packets when 16 or more collisions occur.
=0, The switch will drop packets when 16 or more collisions occur.
