Treatments of Packets:
1. An untagged packet arrives at Port 1
When an
untagged packet arrives at Port 1, port 1‟s Port VLAN ID (11) will be added to the
original port. Because port 24 is set as a trunk port, it will forward the packet with tag 11 out
to the Carrier Ethernet.
2. A tagged packet arrives at Port 1
In most situations, data VLAN will receive untagged packets sent from the client PC or
workstation. If tagged packets are received (possibly sent by malicious attackers), they will
be dropped.
III. Management VLAN
For security and performance reasons, it is best to separate user traffic and management
traffic. When Management VLAN is set up, only a host or hosts that is/are in this
Management VLAN can manage the device; thus, broadcasts that the device receives or
traffic (e.g. multicast) directed to the management port will be minimized.
In the network diagram provided, the management PC on the right would like to manage the
Managed Switch on the left remotely. You can follow the steps described below to set up the
Management VLAN.
