QoS
QoS can let you classify Internet application traffic by source/destination IP
address and port number. You can assign priority for each type of application
and reserve bandwidth for it. The packets of applications with higher priority
will always go first. Lower priority applications will get bandwidth after higher
priority applications get enough bandwidth. This can let you have a better
experience in using critical real time services like Internet phone, video
conference …etc. All the applications not specified by you are classified as rule
name “Others”. The rule with a smaller priority number has a higher priority;
the rule with a larger priority number has a lower priority. You can adjust the
priority of the rules by moving them up or down.
Enable/Disable
QoS
You can check “Enable QoS” to enable QoS
functionality for the WAN port.
Traffic mapping
Click “Add traffic class” then enter a form of the QoS rule.
Click “Apply” after filling out the form the rule will be added into the table.

Edit a QoS rule
Select the rule you want to edit and click “Edit”, then enter
the detail form of the QoS rule. Click “
Apply
” after editing the form and the
rule will be saved.
Adjust QoS rule
priority You can select the rule and click “Move Up” to make
its priority higher. You also can select the rule and click “Move Down” to make
its priority lower.

Routing
These screens define routing related parameters, including static routes and
RIP (Routing Information Protocol) parameters.
Routing Table
Flags Indicates the route status:
C = Direct connection on the same subnet.
S = Static route.
R = RIP (Routing Information Protocol) assigned route.
I = ICMP (Internet Control Message Protocol) Redirect route.
Static Route
Click
Add
to add a new static route to the list, or check the box of
an already entered route and click
Modify
. Clicking
Delete
will remove an
entry from the list.
RIP
RIP mode Globally enables or disables RIP.
Auto summary If Auto summary is disabled, then RIP packets will
include sub-network information from all sub-networks connected to the router.
If enabled, this sub-network information will be summarized to one piece of
information covering all sub-networks.
Table of current Interface RIP parameter Interface The WAN interface to be
configured. Operation Mode Disable: RIP disabled on this interface.
Enable: RIP enabled on this interface. Silent: Listens for route broadcasts and
updates its route table. It does not participate in sending route
broadcasts. Version Sets the RIP (Routing Information Protocol)
version to use on this interface.

Snmp
Use the SNMP configuration screen to display and modify parameters for
the Simple Network Management Protocol (SNMP).
SNMP operation mode
to select the SNMP modes for this device.
Community
A computer attached to the network, called a Network Management
Station (NMS), can be used to access this information. Access rights to the agent
are controlled by community strings. To communicate with the Router, the NMS
must first submit a valid community string for authentication.
Note:
Up to five community names may be entered.

Trap
Specify the IP address of the NMS to notify when a significant event is
detected by the agent. When a trap condition occurs, the SNMP agent sends an
SNMP trap message to any NMS specified as a trap receiver.
IP Address Traps are sent to this address when errors or specific events
occur on the network. Community A community string (password) specified for
trap management. Enter a word, something other than public or
private, to prevent unauthorized individuals from accessing
information on your system. Version Sets the trap status to disabled, or enabled
with V1 or V2c. The v2c protocol was proposed in late 1995 and includes
enhancements to v1 that are universally accepted. These include a get-bulk
command to reduce network management traffic when retrieving a sequence of
MIB variables, and a more elaborate set of error codes for improved reporting to
a Network Management Station.
