PVMAPnn_0,1,3 – Ports 1~9 Configuration Registers
PVMODE
VLAN Mode
0: Port based VLAN Mode (Default)
1: Tag based VLAN Mode
Slow learning (Default = 0)
Same function as SE_OPMODE bit [7]. Either bit can enable the function; both need to
be turned off to disable the feature.
Disable dropping of frames with destination MAC addresses 01-80-C2-00-00-01 to
0x01-80-C2-00-00-0F.
0: Drop all frames in this range (Default)
1: Disable dropping of frames in this range
Flooding control in secure mode
0: Enable - Learning disabled port will not receive any flooding packets (Default)
1: Disable
Support MAC address 0
0: MAC address 0 is not learned. (Default)
1: MAC address 0 is learned.
Default Transmit priority. Used when Bit [7]=1 (Default 0)
Transmit Priority Level 0 (Lowest)
Transmit Priority Level 1
Transmit Priority Level 2
Transmit Priority Level 3 (Highest)
Default Discard priority. Used when Bit [7]=1
0 – Discard Priority Level 0 (Lowest) (Default)
1 – Discard Priority Level 1(Highest)
Enable Fix Priority (Default 0)
0 - Disable. All frames are analysed. Transmit Priority and Discard Priority are
based on VLAN Tag, TOS or Logical Port.
1 - Enable. Transmit Priority and Discard Priority are based on values
programmed in bit [6:3]
This means packet with destination MAC address 0 is forwarded as unknown
destination. It is subjected to unicast to multicast rate control.
