Global Control Register3
Table 12. Global Control Register3
Byte.bit Description
3.7~3.5
Used to classify priority for incoming 802.1Q packets when 802.1p priority
classification is enabled. “User priority” compares against this value.
>=: Classify as high priority
<: Classify as low priority
3.4
1: Combine port 0 and 1 as one trunking port, if trunking is enabled by
strapping pin, Dis_Trunk
0: Combine port 6 and 7 as one trunking port, if trunking is enabled by
strapping pin, Dis_Trunk
3.3~3.2
The frame service ratio between the high priority queue and low priority
queue is:
11=16:1
10=always high priority queue first
01=8:1
00=4:1
3.1
1: The switch will compare both the source and destination IP addresses of
an incoming packet against the value, IP address [A] AND IP mask [A], to
classify priority for the packet
0: The switch will not compare the source or destination IP addresses of an
incoming packet against the value, IP address [A] AND IP mask [A]
3.0
1: The switch will compare both the source and destination IP addresses of
an incoming packet against the value, IP address [B] AND IP mask [B], to
classify priority for the packet
0: The switch will not compare the source and destination IP addresses of
an incoming packet against the value, IP address [B] AND IP mask [B]
