In this section:

Business policy rules allow the system to classify traffic flow into classes of service based on their URL, IP Address, or destination port. When a rule is configured and saved, the system modifies each packet in the flow with the configured data priority. The packet then enters the traffic shaper and based on data priority, the shaper applies the prioritization and bandwidth guarantees for the class-of-service the packet belongs to.

Caution

Enable and configure Traffic Shaping for both the Upstream and Downstream bandwidths in case of Dual WAN support. The WAN connection provides priority through the system for the configured classification rules. When the system is installed and configured for Dual WAN support, be sure to configure both WANs’ Upstream and Downstream bandwidth settings.

Note

When Business Policy rules are added, edited, or deleted, network services are not restarted. Saved changes are reflected immediately on the system.

Refresh

Select to refresh the table. When a new URL rule is added, the system resolves the URL to a DNS A address (i.e., IPv4 address). This field displays Resolving Host. The system also tests to verify which WAN interface provides the best path for traffic when Link Steering is configured for Auto and displays Determining Interface.

Note

When configuring a URL rule type for priority, the system initiates a DNS A query to resolve the URL to IPv4 addresses and then applies the configured priority to these IPs. The DNS A response contains a TTL (time-to-live) value that indicates the time for which this specific DNS record is valid. After this TTL time has expired, the system automatically re-queries the DNS and update the IPv4 address and provide priority to the new IPv4 destination. Click Refresh to fetch the current set of IPv4 addresses of URLs specified in the Classification Rules.

Deleting an existing entry

To delete an existing rule, select the check-box for the rule to be deleted. You can delete one or more rules at the same time. Click the Delete button.

Index

Determines the placement of the rule in the table. Rules are processed by the system from top to bottom. Edit the rule and enter the new index number as desired.

Note

When the index is configured for 0 the rule is added to the top of the list. When no index is specified the rule is added to the bottom of the list.

Name

Displays the configured name for the rule.

Source Address

Displays the configured IP/MAC address for the rule.

Destination FQDN

Displays the configured DNS A record name for the rule.

Destination Address

Displays the configured IPv4, IPv6 or the resolved address associated with the configured FQDN.

Destination Port

Displays the configured destination port assigned to the traffic for the configured rule.

Priority

Displays the configured priority assigned to the traffic for the configured URL.

Link Steering

Displays the interface preference for the configured rule.

Interface

Displays the current interface the rule is using. When the rules’ Link Steering is configured to Auto, the system analyzes traffic and applies the Routing Decision Preference and settings on the Advanced page. This determines which WAN the rules traffic is routed through.

Create a new Classification Rule

Action

Select desired action from drop-down menu:

  • Add New Rule: Select this to define a new classification rule. The maximum number of rules that can added is 75.
  • Edit Rule: Select the rule you wish to edit, then make the desired changes and click the Edit button to save the changes.

Name

This field specifies a unique name for the classification rule. Only alphanumeric, underscore(_), hyphen(-) and dot(.) characters are allowed.

Index

Index specifies the rule placement in the table.

Source Address (IP/MAC)

Specifies the source address. It can be IPv4 or IPv6 or MAC address

Destination Address(IP/FQDN)

The address field can contain an FQDN, a single IPv4 address or a single IPv6 address. When configuring an FQDN, the FQDN must be a DNS A record name. DNS SRV record resolution is not supported.

Destination Port

The destination port can be configured as a single port. When configuring a port, select a specific transport protocol. The protocol cannot be configured when configuring port-based priority.

Note

If Address is entered, the Destination Port cannot be entered. If the Destination Port is entered, Address cannot be entered. Only one of the two can be entered.

Priority

This value determines which Class of Service the flow belongs to. Apart from setting Classes of Service, it provides the functionality to Drop the configured flow as well. Use the Drop option.

The system displays the class of service name that is created on the Advanced page. The system does not permit data flows to be assigned to the Voice class queue. The traffic priority can be set as either High, Medium or Low.

Note

It is not recommended to set the traffic priority to Low even though the setting is available.

Note

Business Policy does not execute a config_network to make the changes happen. The changes come into effect immediately.

Link Steering

Specifies the preferred link for data flow routing. Choose an option from the drop-down list:

  • Auto – Auto option allows the system to determine the desired link depending on the Routing Decision Preference and settings on the Advanced page.

    Preference to WLR data interface for Auto rules is only considered at startup and not for subsequent link failures.

  • WAN 1 – Forces this rules traffic flow to the WAN 1 interface.
  • WAN 2 – Forces this rules traffic flow to the WAN 2 interface.
