OfficeConnect VPN Firewall User’s Manual Chapter 5. Configuring LAN Settings

6 Configuring VLAN Settings

6.1 VLAN Overview

VLANs are logical su/jointfilesconvert/62153/bgroups with a Local Area Network (LAN) which combine

user stations and network devices into a single unit, regardless of the physical

LAN segment to which they are attached. VLANs allow network traffic to flow

more efficiently within su/jointfilesconvert/62153/bgroups. VLANs use software to reduce the amount of

time it takes for network changes, additions, and moves to be implemented.

VLANs restrict traffic within the VLAN.

VLANs have no minimum number of ports, and can be created per unit, per

device, or through any other logical connection combination, since they are

software-based and not defined by physical attributes.

VLANs function at Layer 2. Since VLANs isolate traffic within the VLAN, a Layer

3 router working at a protocol level is required to allow traffic flow between

VLANs. Layer 3 routers identify segments and coordinate with VLANs. VLANs

are Broadcast and Multicast domains. Broadcast and Multicast traffic is

transmitted only in the VLAN in which the traffic is generated.

VLAN tagging provides a method of transferring VLAN information between

VLAN groups. VLAN1is the default VLAN. All ports are untagged members of

VLAN1 by default. If any port becomes an untagged member of a different

VLAN, then the port is removed from untagged membership of VLAN1. For

example: If port 24 is made an untagged member of VLAN 5, the port will no

longer be a member of VLAN1. However, if the port is made an tagged member

of VLAN5, it still remains untagged in VLAN1.

A port can only be an untagged member of one VLAN. By default it is untagged

member of VLAN1. The system cannot remove its untagged membership from

the present VLAN directly, it has to add the port as one of the untagged

membership in a new VLAN.

There is no restriction on tagged membership. A port can be a tagged member

of any number of multiple VLANs.

6.2 VLAN Configuration Parameters

Table 6.1 describes the configuration parameters available for VLAN

configuration.

Table 6.1 VLAN Configuration Parameters

Setting

Description

VLAN ID

Specifies the VLAN ID to which the port is assigned.

Tag Port

Specifies a physical port to be a tagged member of a

VLAN.

Untag Port

Specifies a physical port to be a untagged member of a

VLAN.

6.3 Configuring the VLAN settings

Follow these steps to change the VLAN settings.

1. Log into Configuration Manager as administrator, and then click the

Network menu.

When the submenus of Network menu displays, clicks VLAN submenu
