5 VLANs
5.1 Introduction
VLANs (Virtual Local Area Networks) allow one network to be divided into multiple logical
subnets. The terminal equipment connected to the ports of a switch in the same VLAN
are able to communicate with each other as defined by their logical relationship rather
than their physical connectivity.
The members of the VLAN need to be set as either tagged or untagged. If a port is set to
be untagged it is an access port. This is used to connect an end station that is VLAN-
unaware, this port provides connectivity through the switch without the actual end
station being required to support VLAN tagging. If a port is untagged the priority of the
port can be set from 0 to 7.
A tagged port is a trunk port. This port is used to interconnect switches that are in the
VLAN-aware domain. The VLAN-aware switch receives the untagged frames from the
end stations, applies the VLAN association rules, and forwards the frames with a tag.
5.2 VLAN configuration
5.2.1 VLAN port configuration
A VLAN port has two transmitting modes: drop and forward
Setting drop mode for VLAN port
SWITCH(config)#vlan vlanmode drop
Setting forward mode for VLAN port
SWITCH(config)#vlan vlanmode forward
Configuring a VLAN port
Enter the port configuration menu and configure VLAN 2.
SWITCH(config)#vlan 2
