Ipv4 and Ipv6 Priority Look Up
If a Broadcast frame is received, the switch Hardware sends the received frame to all output
ports, except the one from which it was received (Flooding).
29.4.9.2 Forced Forwarding
The MAC address lookup result can be overwritten using the forced forwarding configuration
available in the register FORCE_FWD_P0. This feature is available only for frames coming
from the local port (Port 0).
When forced forwarding is enabled for a frame, the frame will be forwarded to the forced
destination port(s), ignoring any results from the MAC destination address lookup. Forced
forwarding only replaces the mac lookup function, all other filtering functions (for example,
VLAN verification) act as normal.
29.4.9.3 Learning
The Switch Hardware extracts the source MAC address of each frame received on each of
the switch ports and provides it, through the registers
the Switch Firmware which implements the learning task. The register
indicates availability of learning data.
Learning Interface
The interface implements a FIFO buffer that stores up to 32 words of 32-bit each.

• The Switch engine sends the received frame to all ports except the port on which
it was received (Flooding).
Flooding and additional frame filtering can be controlled, for
example, to avoid the duplication of critical information to
unwanted destinations, with the mechanism described in Section
5.10.3 page 41.
