BITS

Upper 32-bits of the 64-bit Hash Table
Host MAC Multicast Hash Table High Register (HMAC_HASHH)
The 64-bit Multicast table is used for group address filtering. For hash filtering, the contents of the
destination address in the incoming frame is used to index the contents of the Hash table. The most
significant bit determines the register to be used (Hi/Low), while the other five bits determine the bit
within the register. A value of 00000 selects Bit 0 of the Multicast Hash Table Lo register and a value
of 11111 selects the Bit 31 of the Multicast Hash Table Hi register.
If the corresponding bit is 1, then the multicast frame is accepted. Otherwise, it is rejected. If the “Pass All
Multicast” (MCPAS) bit of the
accepted regardless of the multicast hash values.
The Multicast Hash Table High register contains the higher 32 bits of the hash table and the Multicast
Hash Table Low register contains the lower 32 bits of the hash table. Refer to
Filtering," on page 115
This table determines if the Host MAC accepts the packets from the switch fabric. The switch fabric
address table and configuration determine the packets that get sent to the Host MAC.
