should be unique. If both are set to the same value, VLAN1 is given higher precedence and the
maximum legal frame length is set to 1522.
The Ethernet address fields of an Ethernet packet consist of two 6-byte fields: one for the destination
address and one for the source address. The first bit of the destination address signifies whether it is
a physical address or a multicast address.
The Host MAC address check logic filters the frame based on the Ethernet receive filter mode that has
been enabled. The various filter modes of the Host MAC are specified based on the state of the control
bits in the
14.3.1, "Host MAC Control Register (HMAC_CR)," on page 272
If the frame fails the filter, the Host MAC does not receive the packet. The host has the option of
accepting or ignoring the packet.
Note: This filtering function is performed after any switch fabric filtering functions. The user must
