Configuring IP QoS

This section describes how to configure an IP QoS rule. By configuring an IP QoS rule, you can specify a max bandwidth or reserved bandwidth available to each IP or shared by all the IPs within the IP range.

Creating an IP QoS Rule

To create an IP QoS rule, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, click New on the upper-left of the QoS rule list.
  3. On the Basic tab in the IP QoS dialog, configure basic options for the IP QoS rule.
    The options are described as below:
    Type Description
    Rule name Specifies a name for the rule.
    Apply to

    Specifies a QoS object which can be an interface or security zone.

    • Interface: Specifies an interface the rule will be applied to.
    • Zone: Specifies a security zone the rule will be applied to.
    IP

    Specifies an IP range or address entry for the IP QoS rule.

    • IP range: Type the start IP and end IP into the boxes.
    • Address entry: Select an address entry from the drop-down list.
    Add: Click Add to add the configured entry to the list below. You can add up to 8 entries.
    Delete: Click Delete to delete the selected entry.
    Output BW

    Specifies a control policy for the output bandwidth. Select Per IP or Share from the drop-down list, and then type bandwidth values into the boxes behind. To specify a schedule during which the bandwidth restriction will take effect, select a schedule from the Schedule drop-down list.

    • Per IP: Specifies the bandwidth to the the max bandwidth or reserved bandwidth available to each IP within the IP range.
    • Share: Specifies the bandwidth to the the max bandwidth or reserved bandwidth shared by all the IPs within the IP range.
    • Max BW: Specifies a max bandwidth, i.e., the max bandwidth shared by all the IPs or available to each IP within the IP range. The value range is 32 to 1000000 Kpbs.
    • Reserved BW: Specifies a reserved bandwidth, i.e., the reserved bandwidth shared by all the IPs or available to each IP within the IP range. The value range is 32 to 1000000 Kpbs. This value must be smaller than the actual bandwidth value of the interface.
    • Schedule: Specifies a schedule during which the bandwidth restriction will take effect.
    Add: Click Add to add the bandwidth restriction.
    Delete: Click Delete to delete the bandwidth restriction.
    Input BW

    Specifies a control policy for the output bandwidth. Select Per IP or Share from the drop-down list, and then type bandwidth values into the boxes behind. To specify a schedule during which the bandwidth restriction will take effect, select a schedule from the Schedule drop-down list.

    • Per IP: Specifies the bandwidth to the the max bandwidth or reserved bandwidth available to each IP within the IP range.
    • Share: Specifies the bandwidth to the the max bandwidth or reserved bandwidth shared by all the IPs within the IP range.
    • Max BW: Specifies a max bandwidth, i.e., the max bandwidth shared by all the IPs or available to each IP within the IP range. The value range is 32 to 1000000 Kpbs.
    • Reserved BW: Specifies a reserved bandwidth, i.e., the reserved bandwidth shared by all the IPs or available to each IP within the IP range. The value range is 32 to 1000000 Kpbs. This value must be smaller than the actual bandwidth value of the interface.
    • Schedule: Specifies a schedule during which the bandwidth restriction will take effect.
    Add: Click Add to add the bandwidth restriction.
    Delete: Click Delete to delete the bandwidth restriction.
  4. On the Advanced tab, configure the options as below:
    FlexQoS: Configure this function for the input and output bandwidth.
    Enable - Select this check box to enable FlexQoS.
    Max BW - If FlexQoS is enabled, this options is used to specify the max flex bandwidth, i.e., the upper threshold of the increased bandwidth. The value range is 64 to 1000000 Kbps. The default value is 100 times of the specified bandwidth.
    Fine-grained control: Nest an application QoS rule for the IP QoS rule. System will allocate different application bandwidth for different IPs based on the specified application QoS rule, thus realizing a fine-grained IP QoS control. You can configure this function for input or output bandwidth. Click Nest Application QoS Rule, and in the Nest Application QoS dialog, configure options. The available options are the same with those of application QoS configuration. To edit/delete a nest application QoS rule, click or under Operation.
  5. Click OK to save your settings.

Tip: To switch to role QoS mode, click Switch to Role QoS.

Editing an IP QoS Rule

To edit an IP QoS rule, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select the IP QoS rule you want to edit from the rule list, and click Edit. In the IP QoS dialog, modify according to your need.
  3. Click OK to save your changes.

Deleting an IP QoS Rule

To delete an IP QoS rule, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select the IP QoS rule you want to delete from the rule list, and click Delete.

Enabling/Disabling an IP QoS Rule

To enable/disable an IP QoS rule, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select the IP QoS rule you want to enable/disable from the rule list, and click Enable/Disable.

Viewing an IP QoS Rule

To view an IP QoS rule, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select Interface, Zone or ALL from the Apply to drop-down list.

All the configured QoS rules for the selected interface/zone or all the interfaces/zones are listed in the IP QoS list.

Adjusting Priority

For the QoS rules that are bound to the same interface or security zone, system will match the rules displayed in the QoS rule list in a descending order, i.e., the upper the rule is, the higher its priority is.

To adjust a QoS rule's position, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, click Priority on the upper-right of the IP QoS rule list.
  3. In the Adjust Priority dialog, select an IP QoS rule and click Up, Down, Top or Bottom to move the rule.
  4. Click OK to save your changes.

Configuring an IP Address Whitelist

QoS supports IP address whitelist. With whitelist configured, system will not set any QoS restriction on the specified traffic.

To configure an IP address whitelist, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select an IP range or address entry that is not restricted by the QoS rule from the Whitelist drop-down list:
    IP range - Type the start IP and end IP into the boxes.
    Address entry - Select an address entry from the drop-down list.
  3. Click OK to save your settings.

Specifying a Schedule

To specify a schedule during which the IP QoS rule will take effect, take the following steps:

  1. On the Navigation pane, click Configure > Content > QoS to visit the QoS Configuration page.
  2. On the IP QoS tab, select a schedule from the Schedule drop-down list, and click Add.
  3. Click OK to save your settings.
