EnlPPr
I/Opd 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
142
IPTosMap1
I/Opd IP type of service mapping - the most significant bit
IPTosMap(1) is latched on reset
143
IPTosMap0
I/Opu 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. The resolution function is used for the final priority
class if the receiving port already has a priority level assigned by
PriClass configuration, or the VLAN prioritization is active.
IPTosMap(0) is latched on reset.
144
EnVLANPr
I/Opu 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
145
VLANPrMap1
I/Opu VLAN priority mapping
VLANPrMap(1)is latched on reset.
