802.1Q Port base VLAN
With port-based VLAN membership, the port is assigned to a specific VLAN independent
of the user or system attached to the port. This means all users attached to the port
should be members of the same VLAN. The network administrator typically performs the
VLAN assignment. The port configuration is static and cannot be automatically changed
to another VLAN without manual reconfiguration.
As with other VLAN approaches, the packets forwarded using this method do not leak into
other VLAN domains on the network. After a port has been assigned to a VLAN, the port
cannot send to or receive from devices in another VLAN without the intervention of a
Layer 3 device.
The device that is attached to the port likely has no understanding that a VLAN exists. The
device simply knows that it is a member of a subnet and that the device should be able
to talk to all other members of the subnet by simply sending information to the cable
segment. The switch is responsible for identifying that the information came from a
specific VLAN and for ensuring that the information gets to all other members of the
VLAN. The switch is further responsible for ensuring that ports in a different VLAN do not
receive the information.
This approach is quite simple, fast, and easy to manage in that there are no complex
lookup tables required for VLAN segmentation. If port-to-VLAN association is done with
an application-specific integrated circuit (ASIC), the performance is very good. An ASIC
allows the port-to-VLAN mapping to be done at the hardware level.
Default Settings
The default PVID is 1 for all ports.
The default Acceptable Frame is All for all ports.
All ports join in the VLAN 1.
Notice: The maximum VLAN group is 4094.
CLI Configuration
Node
Command
Description
enable
show vlan VLANID
This command displays the VLAN
configurations.
configure
vlan <1~4094>
This command enables a VLAN and enters
the VLAN node.
configure
no vlan <1~4094>
This command deletes a VLAN.
vlan
show
This command displays the current VLAN
configurations.
vlan
name STRING
This command assigns a name for the
specific VLAN.
The VLAN name should be the combination
of the digit or the alphabet or hyphens (-) or
underscores (_).
The maximum length of the name is 16
characters.
vlan
no name
This command configures the vlan name to
default.
Note: The default vlan name is
“VLAN”+vlan_ID, VLAN1, VLAN2,…
vlan
add PORTLISTS
This command adds a port or a range of
ports to the vlan.
vlan
fixed PORTLISTS
This command assigns ports for permanent
member of the vlan.
vlan
no fixed PORTLISTS
This command removes all fixed member
from the vlan.
vlan
tagged PORTLISTS
This command assigns ports for tagged
member of the VLAN group. The ports
should be one/some of the permanent
members of the vlan.
