VLANs
197
The communication relationships here are as follows: terminal devices at
ports 1 and 4 of the left device and terminal devices at ports 2 and 4 of the
right device are members of VLAN 2 and can thus communicate with each
other. The behavior is the same for the terminal devices at ports 2 and 3
of the left device and the terminal devices at ports 3 and 5 of the right
device. These belong to VLAN 3.
The terminal devices “see” their respective part of the network.
Participants outside this VLAN cannot be reached. Broadcast and
Multicast data packets, and Unicast packets with unknown (unlearned)
destination addresses, are also only sent within a VLAN.
Here, VLAN tagging (IEEE 801.1Q) is used within the VLAN with the ID 1
(Uplink). You can see this from the letter T in the egress table of the ports.
The configuration of the example is the same for the device on the right.
Proceed in the same way, using the ingress and egress tables created
above to adapt the previously configured left device to the new
environment.
