The switch is modularized. In addition to two GBIC ports, there are three
modules selectable for your needs. For the different type modules, some
module/port settings maybe need to be reconfigured. You can configure
the module type by this function. The system can also configure all the
port settings of the module to the pre-defined values for you. If some of
the detail settings of each port do not meet your needs, you can change
them on a port-by-port basis from the Port Controls Page. The default
module type is 8-port 10/100 Base-TX RJ-45.
Available module types:

change the address.
Note: The user must reset/restart the Switch in order to use the new
IP address setting.
2-5-2. Advanced
Miscellaneous Setting:
MAC Address Age-out Time: Type the number of seconds that an
inactive MAC address remains in the switch's address table. The valid
range is 300~765 seconds. The default is 300 seconds.
Max bridge transmit delay bound control: Limit the packets queuing
time in the Switch. If enable, the packets queued exceed this time will be
dropped. This valid value are 1 sec, 2 sec, 4 sec and off.
Enable Low Queue Delay Bound: Limit the low priority packets queuing
time in Switch. If the low priority packets stay in Switch exceed the Max
Delay Time, it will be sent. The valid range is 1~255 ms.
NOTE: Make sure that “Max bridge transit delay bound control” is
enabled before activating the Delay Bound.
Modularized 24+2G Switch
Broadcast Storm Filter: To configure broadcast storm control, enable it
and set the upper threshold for individual ports. The threshold is the
percentage of the port's total bandwidth used by broadcast traffic. When
broadcast traffic for a port rises above this threshold, broadcast storm
control will activate. The valid threshold values are 5%, 10%, 15%, 20%,
25% and OFF.
Priority Queue Service settings:
First Come First Service (FCFS): The sequence of packets sent
depends on the order they arrive.
All High before Low (AHBL): The high priority packets are sent before
low priority packets.
Weighted Round Robin (WRR): Select the preferred ratio of high and
low priority packets sent by the switch in its priority queue. These options
represent the number of high priority packets sent before one low priority
packet is sent. For example, 5 High: 2 Low, means that the Switch sends
5 high priority packets before sending 2 low priority packet.
QoS Policy - Priority Levels:
designated high or low priority.
Collisions Retry Forever: Disable – In half-duplex, if collision occurs,
0~7 QoS levels can be assigned to

Half: User can set half – flow control (backpressure).
14
Modularized 24+2G Switch
6. Rate Control: port1 ~ port 24, supports by-port ingress and egress
rate control. For example, assume port 1 is 10Mbps, users can set its
effective egress rate to 1Mbps, ingress rate is 500Kbps. The Switch
will perform flow control or backpressure to confine the ingress rate to
meet the specified rate.
Ingress: Type the port effective ingress rate. The valid range is 0 ~
1000. The unit is 100K
0: disable rate control.
1 ~ 1000: valid rate value
Egress: Type the port effective egress rate. The valid range is
0~1000. The unit is 100K.
0: disable rate control.
1 ~ 1000: valid rate value.
7. Priority:
This static priority based on port, if you set the port to high
priority, the priority of incoming frames to this port will always be high
8. Port Security: A port in security mode will be “locked” without
permission of address learning. Only the incoming packets with
SMAC already existing in the address table can be forwarded . User
can disable the port from learning any new MAC addresses, then use
the static MAC addresses screen to define a list of MAC addresses
that can use the secure port. Enter the settings, then click Apply to set
the Switch with information provided on this page.
2-5-5. Trunking
The Link Aggregation Control Protocol (LACP) provides a standardized
means for exchanging information between Partner Systems on a link to
allow their Link Aggregation Control instances to reach agreement on the
identity of the Link Aggregation Group to which the link belongs. Move the
link to that Aggregation Group and enable its transmission and reception
functions in an orderly manner.
Link aggregation lets you group up to eight consecutive ports into a single
dedicated connection. This feature can expand bandwidth to a device on
the network. LACP operation requires full duplex mode, more detail
information refers to IEEE 802.3ad.
Modularized 24+2G Switch
2-5-5-1. Aggregator Setting
System Priority: A value used to identify the active LACP. The Switch
with the lowest value has the highest priority and is selected as the active
LACP.
1. Group ID: There are seven trunk groups to provide configures.
Choose the "group id" and click "Get".
2. LACP:
If enable, the group is LACP static trunking group. If disable,
the group is local static trunking group. All ports support LACP
dynamic trunking group. If connecting to the device that also supports
LACP, the LACP dynamic trunking group will be created
automatically.
3. Work ports: Allow max. four ports can be aggregated at the same
time. If LACP static trunking group, the exceed ports are standby and
able to aggregate if work ports fail. If local static trunking group, the
number must be the same as the group member ports.
4. Select the ports to join the trunking group. Allow max. four ports can
be aggregated at the same time.
5. If LACP enable, you can configure LACP Active/Passive status in
each port on State Activity page.
6.
Click Apply.

16
Modularized 24+2G Switch
2-5-5-2. Aggregator Information
When setting LACP aggregator, you can view related information as
follows.
1. This page provides LACP current status. In this case, NO GROUP
ACTIVE, since LACP is not enabled.
2. This page displays Static Trunking groups.
Modularized 24+2G Switch
2-5-5-3. State Activity
Active (select): The port automatically sends LACP protocol packets.
Passive (no select): The port does not automatically send LACP protocol
packets, and respond only if it receives LACP protocol packets from
another networking device.
1. A link having either two active LACP ports or one active port can
perform dynamic LACP trunking. A link has two passive LACP ports
will not perform dynamic LACP trunking because both ports are
waiting for LACP protocol packet from another networking device.
2. If you are active LACP’s actor, when you select trunking port, the
active status will be created automatically.

2-5-6. Filter Database
2-5-6-1. IGMP Snooping
Modularized 24+2G Switch
Modularized 24+2G Switch
2-5-6-2. Static MAC Address
When you add a static MAC address, it is stored in the Switch's address
table regardless of whether the device is physically connected to the
Switch. This saves the Switch from having to re-learn a device's MAC
address when the device is disconnected or powered-off, and is then
active on the network again.
The Switch supports IP multicast, you can enable IGMP protocol on web
management’s switch setting advanced page, then display the IGMP
snooping information in this page You can view different multicast group,
VID and member ports here. IP multicast addresses range from 224.0.0.0
to 239.255.255.255.
The Internet Group Management Protocol (IGMP) is an internal protocol
of the Internet Protocol (IP) suite. IP manages multicast traffic by using
switches, routers, and hosts that support IGMP. Enabling IGMP allows
the ports to detect IGMP queries and report packets and manage IP
multicast traffic through the Switch. IGMP have three fundamental types
of messages. See table below:
Message Description
Query A message sent from the querier (IGMP router or switch) asking for a
response from each host belonging to the multicast group.
Report A message sent by a host to the querier to indicate that the host wants
to be or is a member of a given group indicated in the report message.
Leave Group A message sent by a host to the querier to indicate that the host has
quit to be a member of a specific multicast group.

1. From the main menu, click administrator Filter Database Static MAC
Address.
2. In the MAC address box, enter the MAC address to and from which
the port should permanently forward traffic, regardless of the device’s
network activity.
3. In the Port Number box, enter a port number.
4. If tag-based (IEEE 802.1Q) VLANs are set up on the Switch, static
addresses are associated with individual VLANs. Type the VID
(tag-based VLANs) associated with the MAC address.
5. Click on the Add button.
20
Modularized 24+2G Switch
2-5-6-3. MAC Filtering
MAC address filtering allows the Switch to drop unwanted traffic. Traffic is
filtered based on the destination addresses.
Modularized 24+2G Switch
2-5-7. VLAN Configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the
broadcast domain. It allows you to isolate network traffic so only members
of the VLAN receive traffic from the same VLAN members. Basically,
creating a VLAN in a switch is logically equivalent of reconnecting a group
of network devices to another Layer 2 switch. However, all the network
devices are still plug into the same switch physically. The Switch supports
port-based, 802.1Q (tagged-based) and protocol-based VLAN in web
management page. In the default configuration, VLAN support is disabled.
There are a few configuration examples in Appendix B for your reference.
1. In the MAC Address box, enter the MAC addresses that are to be
filtered.
2. If tag-based (802.1Q) VLAN are set up on the Switch, in the VLAN ID
box type the VID associated with the MAC address.
3. Click the on Add button.
4. Choose the MAC address that you want to delete and then click on
the Delete button
.
21
NOTE: Change VLAN mode for every time, you have to reboot the
Switch for valid value.
Support Port-based VLAN
Packets can go among only members of the same VLAN group. Note all
unselected ports are treated as belonging to another single VLAN. If the
port-based VLAN is enabled, the VLAN-tagging is ignored.

Modularized 24+2G Switch
Support Tag-based VLAN (IEEE 802.1Q VLAN)
Tagged-based VLAN is an IEEE 802.1Q specification standard.
Therefore, it is possible to create a VLAN across devices from different
switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into
the Ethernet frames. Tags contain a VLAN Identifier (VID) that indicates
the VLAN numbers.
Support Protocol-based VLAN
In order for an end station to send packets to different VLANs, it has to
either:
a. Be capable of tagging packets it sends with VLAN tags, OR
b. Be attached to a VLAN-aware bridge that is capable of
classifying and tagging the packet with different VLAN ID based
on not only default PVID but also other information about the
packet, such as the protocol.
The feature can be applied for accommodating devices that you want to
participate in the VLAN, but don’t support tagging. Therefore, the system
can add VAN tags to untagged frames which are based on PVID or on
different protocols.
The Switch will support protocol-based VLAN classification by means of
both built-in knowledge of layer 2 packet formats used by selected
popular protocols, such as Novell IPX and AppleTalk’s EtherTalk, and
some degree of programmable protocol matching capability. A port can
join more than one different protocol VLANs, but a port can’t apply a
same protocol twice for the VLAN configuration purpose. Otherwise you
will see the error message: “Save fail for ethertype conflict” when trying to
configure VLANs.

2-5-7-1. Port Based VLAN
1. Click Add to create a new VLAN group.
2. Enter the VLAN name, group ID and select the members for the new
VLAN.
3. Click Apply.
4. If there are many groups that over the limit of one page, you can click
the “NextPage” to view other VLAN groups.
NOTE: If the trunk groups exist, they are displayed as: TRK1,
TRK2, …, in select menu of ports, and you can configure it to be the
member of the VLAN or not.

2-5-7-2. 802.1Q VLAN
Use this page to create tag-based VLANs, and enable or disable GVRP
protocol. There are 256 VLAN groups provided in the Switch. Enable
802.1Q VLAN, all ports on the Switch belong to a default VLAN. Its VID is
1. The default VLAN cannot be deleted.
Modularized 24+2G Switch
Basic
Create a VLAN and add tagged member ports to it.
GVRP (GARP [Generic Attribute Registration Protocol] VLAN
Registration Protocol) GVRP allows automatic VLAN configuration
between the Switch and nodes. If the Switch is connected to a device with
GVRP enabled, you can send a GVRP request using the VID of a VLAN
defined on the Switch. The Switch will automatically add that device to the
existing VLAN.
25
The above screen is the Main Tag-based VLAN page
1. From the main menu, click administrator VLAN configuration,
click Add then you will see the page as follow.
2. Type a name for the new VLAN.
3. Type a VID number (between 2-4094). The default is 1 (In total,
there are 255 VLANs that can be configured).
4. Choose the protocol type. If you are not applying protocol VLAN,
you must set the value to “NONE”. You can’t set a port to join
more than one VLANs/VIDs with a same protocol.
5. From the Available ports box, select ports to add to the switch
and click “Add >>”. If the trunk groups exist, you can see
displayed as: TRK1, TRK2, …, …, and you can configure it to bet
a member of the VLAN or not.
6. Click Next. Then you can view the page as follow.

7. After adding ports to the VLAN, you use the above page to set the
outgoing frames as VLAN-tagged frames or not. The default is
‘Untag’. Using the dropdown box, select ‘Tag’ or ‘Untag’ and click
Apply.
Note: Unless you are sure the network has no tag-unaware devices, you should leave the
default setting of the outgoing frames to “Untag”.
Tag: Outgoing frames with VLAN-tagging.
Untag: Outgoing frames without VLAN-tagging.
Configure port VID settings
From the main tag-based (IEEE 802.1Q) VLAN page, click Port VID
Settings. Configure port VID settings
From the Main Tag-based VLAN page, click
[Port VID] (shown on the insert to the right) to
enter the Port VID Settings menu.
Port VID (PVID)
Set the port VLAN ID that will be assigned to untagged traffic on a given
port. This feature is useful for accommodating devices that you want to
participate in the VLAN but that don’t support tagging. Each port allows
user to set one PVID, the range is 1~4095, default PVID is 1.
Ports may share a same PVID, but all the PVIDs of the ports on the
switch must belong to the same 256 number group segment. (For
example: 1~255, 256~511,…3840~4095). This is in order to allow for
faster Ingress processing of frames. The PVID will be used for VLAN ID
tagging to untagged frames.
Note also that the PVID must be the same as the member VLAN group
IDs that the port belongs to, else the untagged traffic will be dropped.
This is because the port can’t transmit a frame with a VLAN Group ID it
doesn’t belong to. If a port also joins a protocol VLAN, the switch will
apply the protocol VLAN ID to untagged frames first. If the frame doesn’t
meet one of the protocols the port has defined, then the PVID will be
applied for this frame.
Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded.
The Switch has two ingress filtering rule as follows:

28
Modularized 24+2G Switch
Rule 1: Forward only packets with VID matching this port's configured
VID. The default is “Enable”. By default, only the packets with
VID matching this port’s configured VID can pass the port.
Rule 2: Drop Untagged Frame. The default is “Disable”. By default,
untagged packets can pass the port.
2-5-8. Spanning Tree
The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for
avoiding loops in switched networks. When STP is enabled, it ensures that only
one path at a time is active between any two nodes on the network. You can
enable Spanning Tree Protocol on web management’s switch setting advanced
item, select enable Spanning Tree protocol. We recommend that you enable STP
on all switches to ensure that only a single active path on the network exists.
1. From the Spanning Tree Configuration Menu (shown below), you can
create a new value for the STP parameter, then click the Apply button to set
it. You can view spanning tree information the Root Bridge from the same
screen.
Modularized 24+2G Switch
2. You can view spanning tree status about the Switch from the
following screen.
Parameter Description
Priority You can change priority value, A value used to
identify the root bridge. The bridge with the lowest
value has the highest priority and is selected as
the root. Enter a value from 1 through to 65535.
Max Age You can change Max. Age value, the number of
seconds a bridge waits without receiving Spanning
Tree Protocol configuration messages before
attempting a reconfiguration. Enter a time in
seconds from 6 through to 40.
