Chapter 9 VLAN

GS2200-8/24 User’s Guide

The following table describes the labels in this screen.

9.8 Technical Reference

This section provides technical background information on the topics discussed in this chapter.

9.8.1 Create an IP-based VLAN Example

This example shows you how to create an IP VLAN which includes ports 1, 4 and 8. Follow these

steps:

1 Activate this protocol based VLAN.

2 Type the port number you want to include in this protocol based VLAN. Type 1.

3 Give this protocol-based VLAN a descriptive name. Type IP-VLAN.

4 Select the protocol. Leave the default value IP.

5 Type the VLAN ID of an existing VLAN. In our example we already created a static VLAN with an ID

of 5. Type 5.

Table 23 Port Based VLAN Setup

label Description

Setting Wizard Choose All connected or Port isolation.

All connected means all ports can communicate with each other, that is, there are no

virtual LANs. All incoming and outgoing ports are selected. This option is the most flexible

but also the least secure.

Port isolation means that each port can only communicate with the CPU management port

and cannot communicate with each other. All incoming ports are selected while only the CPU

outgoing port is selected. This option is the most limiting but also the most secure.

After you make your selection, click Apply (top right of screen) to display the screens as

mentioned above. You can still customize these settings by adding/deleting incoming or

outgoing ports, but you must also click Apply at the bottom of the screen.

Incoming These are the ingress ports; an ingress port is an incoming port, that is, a port through

which a data packet enters. If you wish to allow two subscriber ports to talk to each other,

you must define the ingress port for both ports. The numbers in the top row denote the

incoming port for the corresponding port listed on the left (its outgoing port). CPU refers to

the Switch management port. By default it forms a VLAN with all Ethernet ports. If it does

not form a VLAN with a particular port then the Switch cannot be managed from that port.

Outgoing These are the egress ports; an egress port is an outgoing port, that is, a port through which

a data packet leaves. If you wish to allow two subscriber ports to talk to each other, you

must define the egress port for both ports. CPU refers to the Switch management port. By

default it forms a VLAN with all Ethernet ports. If it does not form a VLAN with a particular

port then the Switch cannot be managed from that port.

Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these

changes if it is turned off or loses power, so use the Save link on the top navigation panel to

save your changes to the non-volatile memory when you are done configuring.

Cancel Click Cancel to begin configuring this screen afresh.
