Configuring a bandwidth control rule

Procedure

1. On the Configure Bandwidth Control screen, click Create Rule in the Bandwidth Control Rules area.
2. In the Basic information section, configure basic rule information.

   Item	Setting
   Rule name	Specify a unique name for the bandwidth control rule.
   Description	Meaningful description to easily identify the bandwidth control rule.
   Status	Click the toggle to enable or disable the bandwidth control rule. The rule is enabled by default. If you no longer need a bandwidth control rule, delete it instead of disabling it.

3. In the Source section, select the users/groups/private IP address groups and on-premises gateways that the bandwidth control rule applies to.

   Note Bandwidth control rules do not apply to on-premises gateways with ICAP enabled.

4. In the Traffic section, select the URL categories that the bandwidth control rule applies to.
5. In the Schedule section, select the day and time to enforce the bandwidth control rule. You can enforce the rule all the time, or on certain days of the week and hours of the day.
6. In the Bandwidth throttling section, specify the upstream and downstream bandwidth limits and service priority for traffic of the selected URL categories in the bandwidth control rule.
   • Guaranteed bandwidth: bandwidth that can be expected to be provided for traffic that matches the rule.

     Note The guaranteed upstream or downstream bandwidth cannot be greater than the maximum bandwidth. The total guaranteed upstream or downstream bandwidth in all enabled bandwidth control rules cannot exceed the overall bandwidth in Overall bandwidth settings.

   • Maximum bandwidth: upper threshold of bandwidth that can be expected to be provided for traffic that matches the rule.

     Note The maximum upstream or downstream bandwidth in a bandwidth control rule cannot exceed the overall bandwidth in Overall bandwidth settings.

   • Service priority: Whether the transport channel for traffic that matches the bandwidth control rule should be dropped. This allows the transport channel to free up the required resources or pre-empt the resources from another transport channel with a lower service priority during exceptional network resource limitations, for example, network congestion. Service priorities come with the following order from high to low: Premium, High, Medium, Low.
