4.5 Bridge
The Bridge page group contains most layer 2 configurations, like link
aggregation,...etc..
4.5.1 Link Aggregation
The page configures the link aggregation group (port trunking). The switch
can have 7 link aggregation groups.
Show Trunk: Select “Add a new Trunk” for a new created group . Or select
an existed gr oup t o display on the fol l owing fi elds an d p o rt i co ns.
Port Selection Criterion: the algorithm to distribute packets among the
ports of the link aggregation group according to source MAC address,
destination MAC address, source and destination MAC address, source
IP address, destination IP address, or source and destination IP address.
Name: the g r oup na me.
Trunk ID: a number to identify the trunk group besides the group name.
Remove Trunk: Remove the selected tr unk.
Port Icons: th ese po rt i con s ar e li ste d in a way like the fron t pan el. Y ou
have to click on the i con the select the g roup member s. The port can be
removed from the group by clic king the sele cted por t again.
Click

to refresh the settings to current value. To make the configuration
effective, go to “Save Configuration” page, then click
.
SWP-0412/0420G Series L2 Managed Switch User Guide
You have to check the runtime li nk speed and dup lex mode to make sure the
trunk is physically active. Go to Physical Interface and check the link mode in
the runtime status window for the trunk ports. If all the trunk members are in the
same speed and full duplex mode, then the trunk group is set up successfully.
If one of the members is not in the same speed or full duplex mode, the trunk is
not set correctly . Chec k the link partn er and chan ge the setti ngs to have th e
same speed and full duplex mode for all the members of your trunk group.
3 trunk methods are used. It is for per-system, not
per-port
• All the ports in the link aggregation group MUST operate
in full-duplex mode at the same speed.
• All the ports in the link aggregation group MUST be
configured in auto-negotiation mode or full duplex mode.
This configuration will make the full duplex lin k p os sib le. If
you set the ports in full duplex force mode, then the link
partner MUST have the same setting. Otherwise the link
aggregation could operate abnormally.
• All the ports in the link aggregation group MUST have the
same VLAN setting.
• All the ports in the link aggregation group are treated as a
single logical link. That is, if any member changes an
attribute, the others will change too. For example, a trunk
group consists of port 1 and 2. If the VLAN of port 1
changes, the VLAN of port 2 also changes with port 1.

4.5.6 Tagged VLAN
You can set up to 256 VLAN groups and show VLAN group in this page. There
is a default VLAN created by the switch . It cannot be modify at all. This feature
prevents the switch from malfunctions. You can remove any existed VLAN
except the default VLAN.
You can assig n the port to be a tagged po rt or an unt agged port by toggling the
port butt on. Ther e a re th ree ty pe s of bu tto n di spl ay s:
“U” type: unta gged po rt t hat will re move VL AN tag s from t he t ran smitte d
packets.
“T” type: Al l p a cket s tran smitt ed fro m this port will be t agged.
“blank” type: This port is not a member of the VLAN group.
If one unta gge d po rt be lon g s to two o r more VLA N groups at t he same t i me, it
will confuse the swit ch and cause flooding traffi cs. To prevent it, the switch only
allow one untagged port belo ngs to one VLAN at the same ti me. That is, the
untagged port belongs to th e VLAN group which is called “PVID” and
configured in the “Default Port VLAN & CoS” page. If you want to assign an
untagged port from one VLAN to ano ther, you have to remov e it from the
original VLAN , o r cha nge it to be tagg ed in th e origin al VLA N fi rst .

4.7 Security
The switch has the 802.1x port-based security feature. Only authorized hosts
are allowed to acc ess the swi tch por t. Tra ffic is bl ocked for host s failed to
authenticate themselves. The authentication service is provided by a RADIUS
server or t he local da ta ba se in the switch.
The VLAN information for the users/ports should be configured in the
authentication server properly before enabling this feature.
4.7.1 Port Access Control
Port Access Control is used to configure various 802.1x parameters. 802.1x
uses either RADIUS server or local database to authenticate port users.
The first pa r t i s t he B ridge (Glo bal ) settin g s:
• Reau th ent i cation : Once e nabl ed , Th e swit ch w ill try to aut hen ti cate t he
port user ag ain w hen th e re-a uth en ti cation t i me i s up.
• Reau th ent i cation Ti me: I f ' Reaut hen ti ca tio n' i s en able d, thi s i s th e ti me
period the switch uses to re-send authentication request to the port
user.(see above)
• Authentication Method: RADIUS or Local database can be used to
authenticate the port user.
• Quiet Period: If authentication failed either from RADIUS or local database,
the switch waits upon thi s time pe riod before sendi ng anothe r
authenti cation req uest to th e por t user.
• Ret ransmi ssion Time: If the po rt user failed to re spond to au thenti cation
request fro m t he switch, t he sw it ch w aits u pon t hi s time period befo re
sending another authenti cation reque st to the po rt user.
• Max Reauthentication Attempts: Retry count if the port user failed to
respond to authen ticatio n requests from the swit ch.
The second part is the port settings. Please click

allowed to use the port.
• Auth entication Control: If 'force_authorized ' is selected, the selected por t is
forced autho rized. Thus, tr affic from all hosts is allowed to pass. Otherwi se,
if 'force_unauth oriz ed' is selected , the sele cted port is blocked and no
traffic can go through. If 'Auto' is selected, the behavior of the selected port
is controlled by 802.1x protocol . All ports sh ould be set to 'A uto' unde r
normal conditions.

5 Console Interface
This chapter describes how to use console interface to configure the switch.
The switch provides RS232 connectors to connect your PC. Use a terminal
emulator on your PC such as Hype rTer minal and command line interprete r to
configure th e swit ch. You have to set up th e te rmi nal e mulat o r with b aud rate
9600, 8 bi t da ta , n o pa rity , an d 1 stop bi t, an d n o flow con t rol.
Once you enter CLI mode, typ e “?” will di splay all available comman d help
messages. This is very useful when you are not familiar with the CLI
commands. The CLI mode times out when idle for 10 minutes. You have to
login again t o e nte r C LI mode a fte r t he ti meou t.
All the CLI commands are case sensitive. In order to make them easier to use,
you can enter into different category by typing the full command, then this
category becomes you r working cate gory . Thereafte r, you don ’t have to ty pe
“sys” before any sub-commands. For example, “sys” is a command category
including a lot of sub-commands. You don’t have to type “sys” for the
sub-commands once you change your working category to “sys” by ty p i n g
“sys”. The prompt will become “(system name) sys%” when y our w or king
category is “sys”.

6 IP Addresses, Network Masks, and
Subnets
6.1 IP Addresses
This section pert ains on ly to IP addresse s for IPv4 (v ersion 4 of
the Internet Protocol). IPv6 addresses are not covered.
This section a ssume s bas ic kn ow ledge of bin ary num bers, b its,
and bytes. For details on this subject, see Appendix 6.
IP addresses, the Intern et's ver sion o f tele phone number s, are u sed to iden tify
individual node s (co mpute rs or dev i ces ) on th e Int e rnet. Eve ry IP ad d ress
contains four numbers, each from 0 to 255 and separated by dots (periods),
e.g. 20.56.0.211. These numbers are called, from left to right, field1, field2,
field3, and field4.
This style of writing IP addresses as decimal numbers separated by dots is
called dotted decimal notation. The IP address 20.56.0.211 is read "twenty dot
fifty- six dot z ero d o t tw o -el eve n."
6.1.1 Structure of an IP address
IP addresses have a hierarchical de sign similar to tha t of telepho ne number s.
For example, a 7-digit telephone number starts with a 3-digit prefix that
identifie s a group of thousands of telephone lines, and ends with fou r digits that
identify on e spe ci fi c line in tha t g roup.
Similarly, IP addresse s contain two ki nds of info rmation.
Network ID
Identifies a particular network within the Internet or intranet
Host ID
Identifies a particular computer or device on the network
SWP-0412/0420G Series L2 Managed Switch User Guide
The first part of eve ry IP addre ss contai ns the netw ork ID, and th e rest o f the
address contain s the host ID. The length o f the networ k ID depend s on the
network's class (see following section). Table 7 shows the structure of an IP
address.
Table 7. IP address structure
Field1 Field2 Field3 Field4
Class A Network ID Host ID
Class B Network ID Host ID
Class C Network ID Host ID
Following are examples of valid IP addresses:
Class A: 10 .30 .6 .12 5 (n etw ork = 10, host = 30.6 .12 5 )
Class B: 129.88.1 6.49 (ne twor k = 129.88, ho st = 16.49)
Class C: 1 92. 60 .20 1.1 1 (netw o rk = 19 2. 60. 201 , ho st = 11 )
SWP-0412/0420G Series L2 Managed Switch User’s Guide
82
6.1.2 Network classes
The three commonly used network classes are A, B, and C. (There is also a
class D but it has a special use beyond the scope of this discussion.) These
classes have different uses and characteristics.
Class A networks are the Internet's largest networks, each with room for over
16 million hosts. Up to 126 of th ese huge netwo rks can exist, for a total of over
2 billion hosts. Because of their huge size, these networks are used for WANs
and by organizations at the infrastructure level of the Internet, e.g. your ISP.
Class B networks are small er but still quite large, each being able to hold over
65,000 hosts. There can be up to 16,384 class B networks in existence. A
class B network might be appropriate for a large organization such as a
business or government agency.
Class C networ ks are the smal lest, only able to hold 2 54 hosts at most, but the
total possible number o f class C networks exceed s 2 million (2,0 97,152 to be
exact). LANs connected to the Internet are usually class C networks.
Some important notes regarding IP addresses:
The class can be determined easily from field1:
field1 = 1-126: Class A
field1 = 12 8 -191: Class B
field1 = 19 2 -223: Class C
(field1 values not show n are reserved for special uses)
A host ID can have any value except all fields set to 0 or all field s set to 255, as
those values are reserved for special uses.
SWP-0412/0420G Series L2 Managed Switch User Guide
6.2 Subnet masks
A mask looks like a regular IP address, but contains a
pattern of bits that tel ls w hat parts o f an IP addr ess are the
network ID and what parts are the host ID: bits set to 1
mean "this bit is part of the network ID" and bits set to 0
mean "this bit is part of the host ID."
Subnet masks are used to de fine subne t s (what you get after dividing a
network into smaller pieces). A subnet's network ID is created by "borrowing"
one or more bits from the host ID portion of the address. The subnet mask
identifie s these host ID bit s.
For example, consider a class C network 192.168.1. To split this into two
subnets, you w oul d u se the su bne t mask:
255.255.255. 128
It's easie r t o see w ha t 's h appe ning if we write thi s in bi na ry :
11111111. 11 1111 11 . 1 1111 111 .10 000 000
As with any class C address, all of the bits in field1 through field 3 are part of
the network ID, but no te how the mask specifies that the first bit in field 4 is also
included. Since this extra bit has only two values (0 and 1), this means there
are two subne ts. Each subnet uses the re maining 7 bits in field 4 for its ho st IDs,
which range from 0 to 127 (instead of the usual 0 to 255 for a class C address).
Similarly, to split a class C netw ork into four subn ets, the mask is:
255.255.255. 192 or 1111111 1. 11 111 111 . 1 111 1111 .11 000 000
SWP-0412/0420G Series L2 Managed Switch User’s Guide
84
The two extra bits in Field 4 can have four values (00, 01, 10, 11), so there are
four subnets. Ea ch subnet uses the r emainin g six bits in fie ld4 fo r its host ID s,
ranging from 0 to 63.
Sometimes a subne t mask d oes not s pecify any a dditional
network ID bits, and thus no subnets. Such a mask is
called a default subnet mask. These masks are:
Class A: 255.0.0.0
Class B: 255.255.0.0
Class C: 255.255.255.0
These are called default because they are used when a
network is initially configured, at which time it has no
subnets.

7 Troubleshooting
This section gives instructions for using several IP utilities to diagnose
problems. A list of possible problems with suggestion actions is also
provided.
All the known bugs are listed in the release note. Read the release note
before you set up the switch. Contact Customer Support if these
suggestions do not resolve the problem.
7.1 Diagnosing problems using IP utilities
7.1.1 ping
Ping is a command you can use to chec k whether you r PC can recognize
other computers on your network and the Internet. A ping command sends a
message to the computer you specify. If the computer receives the message, it
sends messages in reply. To use it, you must know the IP add ress of the
computer with whi ch you a re trying to communi cate.
On Windows-based computers, you can execute a ping command from the
Start menu. Cli ck the Sta rt button, and then cli ck Run. In the Open te xt box,
type a statement such as the following:
ping 192.168.1.1
Click
. You can substitute any private IP address on your LAN or a
public IP ad d ress for an I nt e rnet site, i f known .
If the target computer receives the message, a Command Prompt window
appears as shown in Figu re 5 2.
SWP-0412/0420G Series L2 Managed Switch User’s Guide
86
Figure 38. Using the ping utility
If the target comput er canno t be locate d, you will receive the message
“Request timed out.”
Using the pin g co mmand, you can test whet he r th e p ath to t he swi t ch is
working (using the pre- configured de faul t LAN IP addre ss 192.168 .1.1 ) or
another addr e ss you a ssigne d.
You can al so te st wheth e r a cce ss to the I nte rne t i s w orki ng by ty ping an
external addr ess, such as that for www.y ahoo.co m (216.1 15.108.2 43). If you
do not know th e IP add ress o f a p a rticula r In te rn et lo cation, you can u se t he
nslookup command, as explained in the following section.
From most other IP-enabled operating systems, you can execute the same
command at a command prompt or through a system administration utility.
SWP-0412/0420G Series L2 Managed Switch User Guide
7.1.2 nslookup
You can use the nslookup command to determine the IP address associated
with an Internet site name. You specify the common name, and the nslookup
command looks up the name on your DNS server (usually located with your
ISP). If that name i s not an ent ry in your ISP’s DNS tabl e, the reque st i s then
referred to ano ther highe r-l evel serv er, and so on, until the entry i s found. The
server then returns the a ssociated IP add ress.
On Windows-based computers, you can execute the nslookup command from
the Start menu. Click the Start button, then click Run. In the Open text box,
type the foll ow ing:
nslookup
Click
. A Command Prompt window displays with a bracket prompt
(>). At the p rompt , ty pe the na me of the Inte rnet addre ss you a re inte rested in,
such as www.absnews.com.
The window display s the associ ate IP add ress, if known . See Figure 39.
Figure 39. Using the nslookup utility
There may be seve ral add resse s as sociat ed with an I nte rnet na me. Thi s i s
common for web site s that receive heavy traffi c; they use multiple, re dundan t
servers to carry the same information.
To exit from the nslookup utility, type exit and press <Enter> at the command
prompt.
