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:

zSFP-SX Transceiver x2
zLC/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.

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.

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.

General Networking
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.

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.
