Physical Switch connection

How to connect two switches via Fiber Channel

Your Switch may come with one or many mini-GB ports. ZyXEL offers Small

Form-factor Pluggable (SFP) transceivers for Gigabit Ethernet and Fiber

Channel applications. These small, modular optical interface transceivers offer

a convenient and cost effective solution for the adoption of Gigabit Ethernet

and Fiber Channel in data center, campus, metropolitan area access, ring

networks, and storage area networks. It supports full duplex Gigabit speeds and hot-pluggable feature.

Scenario

In this scenario, ES-2108-LC is connected to GS-4024 via the mini-GB

Port with a LC/LC Fiber cable (62.5/125MM). PC “Alpha” is connected to

ES-2108-LC and another PC “Delta” is connected to the GS-4024 Switch via

the RJ45 Port.

What you need here to complete this scenario:

(note: Each ES-4124 Switch comes with 2 Mini-GB Port)

z SFP-SX Transceiver x2 z LC/LC Fiber Cable (62.5/125MM) x1

Here is the photo of the SFP-SX Transceiver & the LC/LC Fiber Cable.

Steps to complete this scenario

1. First, pick up your ES-2108-LC and GS-4024Switch and power them up.

ES-4124 Support Notes

Photo of the ES-2108-LC Switch

2. Find both Mini-GB Port on ES-2108-LC and GS-4024.

3. Get one transceiver and plug it into the Mini-GB Port of ES-2108-LC

ES-4124 Support Notes

4. Plug another transceiver into the Mini-GB Port of GS-4024 Switch

ES-4124 Support Notes

5. Remove both side of the protection cap from the LC/LC Fiber Cable.

6. Plug the LC/LC Fiber Cable into the transceivers on both ES-2108-LC and

GS-4024 Switch.

If you connected the cable correctly, the LED of the “LINK” will light up.

ES-4124 Support Notes

7. Now, connect the first PC “Alpha” to ES-2108-LC and the second PC

“Delta” to the GS-4024 via the regular Ethernet cable.

8. Set the NICs in both computers to the same IP Domain.

(ex, PC “Alpha” :192.168.1.4/24; PC “Delta” : 192.168.1.5/24)

9. From PC “Alpha”, PING PC “Delta” at 192.168.1.5

10. From PC “Delta”, PING PC” Alpha” at 192.168.1.4

11. Now you can confirm that the network connection between ES-2108-LC

and GS-4024 is up and running.

DHCP Relay Option 82 Application

ISP may want to limit the number of IP address or deliver some specific IP

addresses according to certain Switch port, VLAN ID and option 82 string.

They can easily to achieve this with DHCP Relay Option 82 feature and a

DHCP server supporting Option 82 function.

ES-4124 Support Notes

How to set up DHCP Relay Option 82 Environment

Here, we will set up an environment to allow a PC to get DHCP IP address in

specific IP pool according to its Switch port, VLAN ID and the option 82 string.

In this case, we are using GS-3012 for the demonstration. PC is behind 25th

Switch port and the option 82 string is a string “GS-3012”. We use the IP

Commander as DHCP server. Its IP is 192.168.1.99 and the IP pool is between

192.168.1.201 and 192.168.1.203 for VID=1, Switch port=25 and the option 82

string is “GS-3012”.

1. Switch (GS-3012) settings

Click IP Application, DHCP Relay in the navigation panel to display configuration

screen as shown. You will see the DHCP Relay setup page. Active

the DHCP relay

and Option 82 function. Also, click Information to make “GS-3012” as the

Option 82 string. Information is READ ONLY here and it is the same as the

host name of the Switch.

Now we can connect PC to the 25th SWITCH port. Please see former

applications for detailed settings.

ES-4124 Support Notes

3. IP Commander settings

Open IP Commander. Right click “IP commander and then click “connect new

server”.

Input the DHCP IP address or domain name and click “ok”. Our IP is

192.168.1.99.

ES-4124 Support Notes

Input user name and password. The default user name is “administrator” and

password is “incognito”.

ES-4124 Support Notes

It will bring up the following screen, please make sure that your DHCP is in

“online” status. Then click “wizard” in the top tool bars and select “rule

wizard”.

ES-4124 Support Notes

Give a name and description to the new rule.

ES-4124 Support Notes

Assign a range of IP addresses or just one IP address to this rule. In our case,

we set the IP pool from 192.168.1.201 to 192.168.1.203.

After input IP pool, we select “DHCP Option” in Keywords combobox.

ES-4124 Support Notes

After select the “DHCP Option”, it will pop up “Add DHCP Option Rule” dialog.

Select “option 82 Relay Agent Information”, sub-option 1, binary data. For port

25, VLAN 1, “GS-3012”, please key in “0019000147532d33303132” as the key

value and click OK. Please note that the first 2 bytes define port number, the

second 2 bytes is VLAN ID and the other bytes are the Option 82 string.

ES-4124 Support Notes

After you finish above step, you will see the following figure.

ES-4124 Support Notes

Then pop up the following screen and you can just press Next button.

Then you can add DHCP template (option) such as gateway, DNS server and

so on.

ES-4124 Support Notes

Here we use “192.168.1.1” as gateway IP address of DHCP client PC.

ES-4124 Support Notes

You can apply DDNS service to DHCP server or not.

The rule creation has been finished.

ES-4124 Support Notes

After finishing all above procedures, your PC will get the IP address

192.168.1.201 when you send a DHCP request.

Separating a physical network into many virtual networks

What is Virtual LAN?

• VLAN Overview

A VLAN (Virtual Local Area Network) allows a physical network to be

partitioned into multiple logical networks. Stations on a logical network belong

to one group called VLAN Group. A station can belong to more than one group.

The stations on the same VLAN group can communicate with each other. With

VLAN, a station cannot directly talk to or hear from stations that are not in the

same VLAN group(s); the traffic must first go through a router.

In MTU or IP-DSLAM applications, VLAN is vital in providing isolation and

security among the subscribers. When properly configured, VLAN prevents

one subscriber from accessing the network resources of another on the same

LAN, thus a user will not see the printers and hard disks of another user in the

same building.

VLAN also increases network performance by limiting broadcasts to a smaller

and more manageable logical broadcast domain. A VLAN group is a broadcast

domain. In traditional Layer-2 switched environments, all broadcast packets go

to each and every individual port. With VLAN, all broadcasts are confined to a

specific broadcast domain.

There are two most popular VLAN implementations, Port-based VLAN and

IEEE 802.1q Tagged VLAN. ES-4124 supports both VLAN implementations.

The most difference between both VLAN implementations is Tagged VLAN

can across Layer-2 switch but Port-based VLAN cannot.

• Port-based VLAN

Port-based VLANs are VLANs where the packet forwarding decision is based

on the destination MAC address and its associated port. You must define
