Configuring Quality of Service (QoS)

The Cisco RV120W lets you configure the following Quality of Service (QoS)

features:

•

Configuring WAN QoS Profiles, page 112

•

Configuring Profile Binding, page 114

•

Configuring CoS Settings, page 115

•

Mapping CoS Settings to DSCP Values, page 116

Configuring WAN QoS Profiles

WAN QoS profiles let you manage the bandwidth of the traffic flowing from the

secure network (LAN) to the insecure network (WAN).

You can configure WAN QoS profiles to control the rate at which the RV120W

transmits data. For example, limiting the outbound traffic helps you prevent the

LAN users from consuming all of the bandwidth of the Internet link.

Configuring Global Settings

To configure the WAN QoS global settings:

STEP 1

Choose QoS > WAN QoS Profiles.

STEP

2

Under

Global Settings

:

a.

To enable WAN QoS, check Enable.

b.

Set the WAN QoS mode by clicking the

Priority

or

Rate Limit

radio button.

The

Priority

option lets you allocate bandwidth based on a priority level.

The

Rate Limit

option lets you specify the total WAN bandwidth (

1

–

100

Mbps).

.

Configuring Profile Binding

After creating WAN QoS profiles, you must bind them to traffic selectors.

To create a profile binding:

STEP 1

Choose QoS > Profile Binding.

STEP

2

In the

Available Profiles

field, choose a WAN QoS profile.

To create a profile, click

Configure Profile

. See

Configuring WAN QoS Profiles,

page 112

for more information.

STEP

3

From the

Service

drop-down menu, choose the service the profile applies to.

If the service you are looking for is not in the drop-down menu, you can configure a

custom service in the Firewall page (see

Creating Custom Services, page 83

.)

STEP

4

From the Traffic Selector Match Type drop-down menu, choose the traffic selector

to use to bind traffic to the profile.

Name

Enter the name of the profile.

Priority

If the WAN QoS mode is set to

Priority

, choose the

priority level from the drop-down menu.

Minimum Bandwidth

Rate

If the WAN QoS mode is set to

Rate Limit

, enter the

minimum bandwidth rate (

1

to total WAN

bandwidth in Kbps).

Maximum Bandwidth

Rate

If the WAN QoS mode is set to

Rate Limit

, enter the

maximum bandwidth rate (

100

–

1000000

Kbps).

Configuring CoS Settings

You can map CoS priority settings to the traffic forwarding queue on the RV120W.

To map CoS priority settings to the traffic forwarding queue:

STEP 1

Choose

QoS

>

CoS Settings

>

Cos Settings

.

STEP

2

In the

CoS to Queue

field, check

Enable

.

STEP

3

For each CoS priority level in the

CoS to Traffic Forwarding Queue Mapping

Table

, choose a priority value from the

Traffic Forwarding Queue

drop-down

menu.

These values mark traffic types with higher or lower traffic priority depending on

the type of traffic.

STEP

Click

Save

.

Starting IP Address

Enter the starting IP address of the range.

Ending IP Address

Enter the ending IP address of the range.

MAC Address

Enter the MAC address for any client device (for

example, a PC or wireless client) to which you want

to assign the bandwidth.

VLAN ID

Choose the VLAN ID on the router to which the

traffic selector applies.

DSCP Value

Enter the Differentiated Services Code Point

(DSCP) value (

0

–

63

).

This value determines how the traffic is prioritized.

Available SSIDs

Choose the SSID the selector applies to from the

drop-down menu.
