1. Brief Introduction of the product
This is a 24 x 10/100Mbps + 2 x 10/100/1000Mbps managed
fast switch. This switch supports many advanced features like
supporting 10/100Mbps half/full duplexe auto negotiation,
MD/MDI-X auto sense, Port-VLAN and Tag-VLAN,
bandwidth control management ect.. It is an ideal choice for
users who are seeking for a higher standard networking
connection with a reasonable price.
2. Networking connection
Connect a device to the switch
When the switch is connected with a 10-base Tx device , pls
use UTP Cat 3 or 5 cable
The length of the cable should comply with the IEEE
standards and max. 100 meters (328ft)
If the switch has a Tx fibre port, you can use long range
fibre to connect the switch. The switch supports
MD/MDI-X auto sense, so you can use straight cable to
connect the workstation or another switch/hub.
Dynamode Ltd
3. Connect with other Switch/Hub
The switch can connect with any 10Mbps or 100Mbps
switch/hub. Since all ports support MD/MDI-X auto sense, so
you can use straight cable or UTP cable to uplink the switch
through any port with other swit ch/hub.
4. Application
The switch can overcome the restriction of hub for uplink, and
improve the overall capacity and performance of the
networking. It can analyse the target address of the dada packet
to decide the forwarding destination of each packet. So the
switch can significately reduce the data flow in the networking.

Below figure shows the segmentation ability of the switch. The
channel dispute of each node is reduced to the minimum, and
the usability of each port is efficiently improved.

7. Management and software introduction
This switch support VLAN, Trunk, QoS, Ports
configuration (enable/disable, auto negotiation, half/full duplex,
flow control) ect. networking management functions. It can be
managed by management software through serial port(RS-232)
or browser.
Management through console port
Dynamode Ltd
Before the management, pls follow below steps:
1. Connet the switch console port with the PC serial port
(RS-232) through the cable enclosed.
2. Run the hyper terminal software of the windows. If your
PC hasn’t installed the hyper terminal software, pls
install it under “ control panel ----> add/delete software
---> Windows installation software ----> Communication
---> Hyper terminal” (Windows 98). For Windows 2000
the hyper terminal is intalled by default.
3. Input the name for the connection in the new link
dialogue.
4. Set the COM port according to the PC main board
( usually COM1).

After setting, switch on the power of the switch. The
software starts and enter into the log interface below:
Note:
If the hyper terminal interface has disorder words or no
reaction, pls check the serial port property settings, and if
the serial port is correctly connected or if the power of
the switch is on.

7-2-2 Port trunking setting
Port trunking is mainly used for improve the uplink
Dynamode Ltd
bandwith for two switches connection. The switch
support non-dynamic load-balance distribution mode
based on port.
Non-dynamic load-balance distribution mode based
on port should be assigned each port flow to the
appointed trunking port according to the actual port flow
in accordance with the principal of average to improve
the bandwidth. The assighment principal is according to
the sequence of the port number averagely.
Note:
This switch is already preset 8 trunk group. The user
can choose to enable the relative Trunk group according
to actual requirement.
7-2-3 Overrall setting
See below figure:

Explanation:
“Half Duplex Back Pressure Flow”
“Broadcast Storm Filtering Control”
“Loop Detect”
7-2-4 QoS setting
QoS function provide two internal sequence system
to support two different level of communication. High
priority and Low priority. The dada flow with High
priority has more short delay with the internal process
of the switch, reduce the time waiting maximumly for
some delay sensitive communication.
See figure below:
17
Dynamode Ltd
Explanation:
“TOS/Diff Serv. Priority”: Enable/Disable
“802.1p Priority”: 802.1p Enable/Disable
“Adapted Flow Control”: If Enable this functi on, during
data transmission, if the port priority is setted High,
the flow control of the port will be disabled
automatically; If the port priority is setted Low, the
flow control of the port will be Enabled
automatically.
“Priority Weighted Ration (High: Low)”: The firmware
preseted 4 kinds of priority, 1:0, 4:1, 8:1, 16:1
seperately. The user can set it according to their
requirement.
Note:
The priority of static port is higher than 802.1p and
OS/Diff Serv.

7-2-5 Priority Tag Insert/Remove
See figure below:
802.1Q VLAN tag principle:
Behind the original MAC address, 4 octet tag
will be inserted. If the Ether type of data package is
0 x8100, it means this data package include
IEEE802.1Q/802.1p tag. In the tag, except for the
above mentioned 2 octet, there are 3 bit priority
information, 1 bit CFI information (Canonical
Format Identifier, used to compress the Token Ring
data package, so it can transmission in the Ethernet),
12 bit VLAN ID(VID). 3 bit priority information is
for 802.1p, VID is identifier of VLAN for 802.1Q.
Since there are 12 bits for VID, so it can set 4094
VLAN.
19
Dynamode Ltd
20
Insert tag ahead the data package, the data
package will increase 4 octet, the information in the
original data package will not change.
EtherType and VLAN ID insert behind the
MAC address (MAC source address), but ahead the
original Ethertype/Length or Logical Link Control.
Since the present data package is longer than the
original, so the CRC(Cyclic Redundancy Check)
should be recount.
Explanation:
“Don’t touch”: Not control to the 802.1Q VLAN
member.
“Remove Tag”: After Enable this, Tag information for
802.1Q VLAN member will be removed.
“Insert Tag (high-priority only)”: After Enable this,
It will insert a tag to the ports with High
priority of the 802.1Q VLAN member.
“Insert Tag (all frame)”: After enable this, it will
insert a tag to all ports of the 802.1Q VLAN
member.
7-2-6 VLAN overall setting
See figure below:
Dynamode Ltd
Explanation:
“VLAN Function”: Enable/Disable VLAN
“Unicast Packet Inter-VLAN Leaky”: Enable/Disable
“ARP broadcast Packet Inter-VLAN Leaky”:
Enable/Disable
“IP Multicast Packet Inter-VLAN Leak”:
Enable/Disable
“802.1Q VLAN tag aware”: Enable/Disable
“Ingress Rule for Acceptable frame types”:
Clasify rules for received frame within
one VLAN
“Admit all Frames”
“Admit only VLAN-Tagged Frames”
“Ingress Rule for Ingress Filtering”:
Enable/Disable

7-2-7 VLAN setting
Virtual Local Area Network (VLAN) is a logical
networking toplogical setting and not a physical
networking design. VLAN can segment the networking
into several broadcasting group logically. In this way, the
data packet can only transmission withing the VLAN.
You can consider a VLAN as a subnet. VLAN can
improve the overall performance and security of data
transmission for the networking.
VLAN connects the networking nods logically and
not physically. Through VLAN you can segment the
networking into several group without change the
physical connection of the devices.
For instance, you can segment the networking according
to below method:
According to department, like one VLAN for
Engineering department, one for Accounting
department and one for Sales department.
According to position levels, like one for directors,
one for managers and one for other staff.
According to users, like one for email users and one
for multimedia users.
