The alphabetic portion of the field defines the type of entry.
The numeric portion defines the input port and output port.
Here,
input port refers to the segment the transmitting device is
on, and
output port refers to the segment the packet is forwarded
to.
About dynamic and static table entries
The bridge treats these two classes of entries differently:
A
dynamic table entry represents the segment location (which
segment the device is connected to). After a reset or on being
powered up, the bridge does not have any dynamic entries in its
forwarding table. However, it is monitoring traffic on both.
