Secondary IP Address
You can specify secondary DNS server IP address here because
your ISP often provides you more than one DNS Server. If your
ISP does not provide it, the router will automatically apply
default secondary DNS Server IP address: 194.98.0.1 to this
field.
The default DNS Server IP address can be found via Online
Status:
If both the Primary IP and Secondary IP Address fields are left
empty, the router will assign its own IP address to local users as
a DNS proxy server and maintain a DNS cache.
If the IP address of a domain name is already in the DNS cache,
the router will resolve the domain name immediately. Otherwise,
the router forwards the DNS query packet to the external DNS
server by establishing a WAN (e.g. DSL/Cable) connection.
After finishing all the settings here, please click
OK
to activate them.
4.2.2 Ports
Ports page is used to change the setting for LAN ports. You can set or reset the following
items. All of them are described in detail below.
Port
It displays current network interface.
Link
It displays current connection status. Green light means the
LAN connection is successful.
Current
It displays current speed that the router uses.
Speed Configured
It can set the speed and duplex of the port. You can use the drop
down list to choose the required speed for the router. If you
have no idea in configuring speed, simple use the default setting,

Auto
.
Flow Control
If flow control is enabled by checking
Configured
box, both
parties can send PAUSE frame to the transmitting device(s) if
the receiving port is too busy to handle. If not, there will be no
flow control in the port. It drops the packet if too much to
handle.
Current Rx: indicates whether pause frames on the port are
obeyed.
Current Tx: indicates whether pause frames on the port are
transmitted.
Maximum Frame
This module offers 1518~9600 (Bytes) length to make the long
packet for data transmission.
Excessive Collision Mode
There are two modes for you to choose when excessive
collision happened in half-duplex condition.
Discard
- It determines whether the MAC drops frames after an
excessive collision has occurred. If yes, a frame is dropped after
excessive collision. This is IEEE Standard 802.3 half-duplex
flow control operation.
Restart
- It determines whether the MAC retransmits frames
after an excessive collision has occurred. If set, a frame is not
dropped after excessive collisions, but the backoff sequence is
restarted. This is a violation of IEEE Standard 802.3, but is
useful in non-dropping half-duplex flow control operation.
Power Control
The Configured column allows for changing the power savings
mode parameters per port.
Disabled
: All power savings mechanisms disabled.
ActiPHY
: Link down power savings enabled.
PerfectReach
: Link up power savings enabled.
Enabled
: Both link up and link down power savings enabled.
Refresh
Click this button to refresh the information for LAN ports.
After finishing all the settings here, please click

to activate them.

4.2.3 MAC Address Table
This page allows you to set timeouts for entries in dynamic MAC Table and configure the
static MAC table here.
Disable Automatic Aging
Stop the MAC table aging timer, the learned MAC address will
not age out automatically. The default setting is enabled. Check
the box to disable this function if required.
Age Time
Delete a MAC address idling for a period of time from the
following MAC Table, which will not affect static MAC
address. Range of MAC Address Aging Time is 10-1000000
seconds. The default Aging Time is 300 seconds.
MAC Table Learning
List the port members which apply dynamic learning
mechanism or not.
Auto
- Enable this port MAC address dynamic learning
mechanism.
Disable
- Disable this port MAC address dynamic learning
mechanism, only support static MAC address setting.
Secure
- Disable this port MAC address dynamic learning
mechanism and copy the dynamic learning packets to CPU.
Static MAC Table Config..
Specify static MAC address with VLAN ID to apply aging
configuration.
Delete -
Click the button to remove the VLAN setting.
VLAN ID -
Specify the interface for the port members.
MAC Address -
It is a six-byte long Ethernet hardware address
and usually expressed by hex and separated by hyphens. For
example, 00 – 40 - C7 - D6 – 00 – 02.
WAN/LAN1~4 -
Check the port to apply this VLAN setting.
To add a new static MAC entry, click
Add new static entry
. A new entry will be shown as
follows. Choose VLAN ID and type a new MAC address. Next, specify port member for this
table. Finally, click OK to save the changes.

4.2.4 VLAN
Virtual LAN function provides you a very convenient way to manage hosts by grouping them
based on the physical port. You can also manage the in/out rate of each port. Go to
LAN
page
and select
VLAN
. The following page will appear. VLAN function is enabled in default.
Add New Private VLAN
Click this button to add a new private VLAN. The router allows
you to add up to 4 VLAN.
To add or remove a VLAN, please refer to the following example.
1.
VLAN 1 is consisted of hosts linked to P1 ~ P4.
2.
After checking the box to enable VLAN function, you will check the table according to
the needs as shown below.

3.
To remove VLAN, click the Delete button for the one you want to remove and click
OK
to save the results.
4.2.5 Monitor Port
It is used to monitor the traffic of the network. For example, we assume that LAN1 and LAN2
are Monitor Port and Monitor ingress Port respectively, thus, the traffic received by LAN2
will be copied to LAN1 for monitoring.
Enable Monitor Port
Check to enable this function.
Monitor Port
Click the one of the LAN ports to specify it for monitoring.
Monitor ingress port
Check to set up the port(s) for being monitored. It only
monitors the packets
received b
y the port you set up.
Monitor egress port
Check to set up the port(s) for being monitored. It only
monitors the packets
transmitted
by the port you set up.
4.2.6 Static Route
Go to
LAN
to open setting page and choose
Static Route
.
Index
The number (1 to 10) under Index displays current static router.
