Description
GMII transmit data - bit 7
Enables IP prioritization. CoS resolution will consider TOS
Precedence bits from IP Header.
‘1’ – IP priority will be taken into consideration
‘0’ – IP priority will be neglected
EnIPPr is latched on reset
GMII transmit data - bit 6
IP type of service mapping - the most significant bit
IPTosMap(1) is latched on reset
GMII transmit data - bit 5
IP type of service mapping - the least significant bit. This
configuration chooses between 4 hard-wired mapping schemes for
the associations of IP priority within the received packet and one of
the 4 priority levels set by PriClass.
In case the receiving port already has a priority level assigned by
PriClass configuration, or the VLAN prioritization is also active, a
resolution function is used for the final priority class.
IPTosMap(0) is latched on reset.
GMII/MII transmit data - bit 4
Enables VLAN prioritization. CoS resolution will consider user priority
bits (TCI field) from 802.1Q VLAN Tag Header.
‘1’ – VLAN priority will be taken into consideration
‘0’ – VLAN priority will be neglected
EnVLANPr is latched on reset
GMII/MII transmit data - bit 3
VLAN priority mapping
VLANPrMap(1)is latched on reset.
Digital +3.3V power supply for I/O
GMII/MII transmit data - bit 2
VLAN priority mapping
This configuration chooses between 4 hard-wired mapping schemes
for the associations of VLAN priority within the received packet and
one of the 4 priority levels set by PriClass.
In case the receiving port already has a priority level assigned by
PriClass configuration, or the IP prioritization is also active, a
resolution function is used for the final priority class.
VLANPrMap(0)is latched on reset.
GMII/MII transmit data - bit 1
Priority class - most significant bit.
PriClass[3] is latched on reset
GMII/MII transmit data - least significant bit
Priority class - least significant bit. Sets priority level per port basis.
PriClass[3] - '00' - port 3 low priority
PriClass[3] - '01' - port 3 has normal priority
PriClass[3] - '10' - port 3 has high priority
PriClass[3] - '11' - port 3 has very high priority
PriClass[3] is latched on reset
