5.6 Port Based VLAN
An administrator can use the PVMAP Registers to configure the MVTX2601 for port-based VLAN. For example,
ports 1-3 might be assigned to the Marketing VLAN, ports 4-6 to the Engineering VLAN, and ports 7-9 to the
Administrative VLAN. The MVTX2601 determines the VLAN membership of each packet by noting the port on
which it arrives. From there, the MVTX2601 determines which outgoing port(s) is/are eligible to transmit each
packet, or whether the packet should be discarded.
Table 2 - PVMAP Register
For example, in the above table, a "
1"
denotes that an outgoing port is eligible to receive a packet from an incoming
port. A
0
(zero) denotes that an outgoing port is not eligible to receive a packet from an incoming port.
In this example:
Data packets received at port #0 are eligible to be sent to outgoing ports 1 and 2
Data packets received at port #1 are eligible to be sent to outgoing ports 0, and 2
Data packets received at port #2 are not eligible to be sent to ports 0 and 1
