entering this port with a DA that is currently 'static' in the ATU. This applies to
unicast as well as multicast frames.
While enabled, the Unicast frames with the management CPU DA can go from
the Eth1 and Eth2 ports in to the CPU port. The static record with the CPU DA
in the ATU table has to be configured (it is pre-configured by default).
Member
(VLAN Table)
In Chip Port based VLAN Table. These parameters are used to restrict which
output ports this input port can send frames to. These parameters (VLANTable
bits) are used for all frames, except for MGMT frames, even if 802.1q is enabled
on this port. These parameters restrict where a port can send frames to (unless
a VLANTunnel frame is being received). If ForceMap (Learning) is enabled, these
parameters indicate which port or ports all frames that ingress this port are sent
to overriding the mapping from the address database.
The default setting prevents sending frames from Eth1 to Eth2 and vice versa.
This is very important to separate different networks (e.g. different customers)
connected to two user ports.
Port association
(PAV)
Port Association Vector for ATU learning. The value in these bits (one bit per
port) is used as the port's DPV on automatic ATU Learning or Entry_State refresh
whenever these bits contain a non-zero value. When these bits are all zero,
automatic Learning and Entry_State refresh is disabled on this port.
For normal switch operation, this port's bit should be the only bit set in the vector.
These bits must only be changed when frames are not entering the port.
The PAV bits can be used to set up port trunking (along with the VLANTable
bits). For the two ports that form a trunk, set both of their port's bits in both port's
PAV registers (this Port association parameter for both ports of the trunk), then
use the VLANTable to isolate the two ports from each other, or to use the Trunk
Mask table to steer the traffic from the other ports down the desired trunk line of
the pair using DA/SA Load Balancing.
