ethLanSwitchNodalVlanTable

It is a 8x32 bytes buffer, each 32 bytes are reserved to a switch
device (IDU of multiplan configuration) according to the
following schema:
              
        +------------------+
block 0 | bytes 0 to 31    |  (Device ID 0)
        +------------------+
block 1 | bytes 32 to 63   |  (Device ID 1)
        +------------------+
block 2 | bytes 64 to 95   |  (Device ID 2)
        +------------------+
block 3 | bytes 96 to 127  |  (Device ID 3)
        +------------------+
block 4 | bytes 128 to 159 |  (Device ID 4)
        +------------------+
block 5 | bytes 160 to 191 |  (Device ID 5)
        +------------------+
block 6 | bytes 192 to 223 |  (Device ID 6)
        +------------------+
block 7 | bytes 224 to 255 |  (Device ID 7)
        +------------------+
              
Every 32 bytes block represents a table of 16x2 bytes words. Each word
is a bit map related to a port of the switch from where a frame
can be received, according to the following association schema:
              
+--------+--------+
| byte 1 | byte 0 |  port 1 (lan 1)
+--------+--------+
| byte 3 | byte 2 |  port 2 (lan 2)
+--------+--------+
| byte 5 | byte 4 |  port 3 (lan 3)
+--------+--------+
| byte 7 | byte 6 |  port 4 (lan 4)
+--------+--------+
        ...
+--------+--------+
| byte 21| byte 20|  port 11 (internal 1)
+--------+--------+
        ...
+--------+--------+
| byte 31| byte 30|  port 16 (...)
+--------+--------+
              
Inside a 2-bytes word, each bit corresponds to a local port,
according to the following schema:
              
byte 0 bit 0 (mask 0x001) enable/disable frames sending to port 1 (lan-1),
byte 0 bit 1 (mask 0x002) enable/disable frames sending to port 2 (lan-2),
byte 0 bit 2 (mask 0x004) enable/disable frames sending to port 3 (lan-3),
byte 0 bit 3 (mask 0x008) enable/disable frames sending to port 4 (lan-4),
...
byte 1 bit 2 (mask 0x0400) enable/disable frames sending to port 11 (internal port 1).
              
Such a map restricts local ports to which the frames received from a
remote switch port can be sent. A one valued bit enables frames to be
sent to the corresponding port, a zero value disables.
