Static MAC address table
User can setup the static MAC address table to force the switching behavior of
IP178C/IP178CH
by
programming MII register 31.14 ~ 30.21. When
IP178C/IP178CH
receives packets, which match
pre-defined MAC address in the table (static_mac_0, static_mac_1), it forwards the packet to MII port
(CPU). The static MAC address table has precedence over the dynamic DA look up result.
In a spanning tree application, the MII register 31.17[10] static_override_0 is “1”, MII register 31.17[9]
static_valid_0 is ”1”, the MII register 31.14~31.16 MAC address field is 01-80-c2-00-00-00 and the MII
register 31.17[8:0] static_port_mask_0 is 9’b1_0000_0000 (MII). That is,
IP178C/IP178CH
only forwards
BPDU to MII (CPU) and in spite of the port states.
MII register R/W
Description
31.17.10
R/W
override_0
1: override the transmission, receiving and learning setting
in MII register 31.13.
0: not override
31.17.9
1: the entry is valid
0: the entry is not valid
31.17[8:0]
Bit 8: forward to port 8 (MII)
Bit 7: forward to port 7
Bit 6: forward to port 6
Bit 5: forward to port 5
Bit 4: forward to port 4
Bit 3: forward to port 3
Bit 2: forward to port 2
Bit 1: forward to port 1
Bit 0: forward to port 0
