Description

BWM Elementals is to provide a method of allowing a single BWM rule to apply to the individual elements of that rule. "Per-IP Bandwidth Management" BWM is introduced as the first "Elemental" feature. This feature is a sub-option of Bandwidth Object. When Per-IP BWM is enabled, each individual IP under its parent rule will be applied to the elemental bandwidth settings.

Resolution

Step 1: Enabling Bandwidth Management Settings

• Login to the SonicWall Management GUI.
• Navigate to the Manage > Security Configuration > Firewall Settings | Bandwidth Management page.
• Select radio-button Advanced under Bandwidth Management Type.
• Click on Accept to save changes.

Note: Every time the Bandwidth Management Type is changed, all bandwidth management settings on the Firewall Rules will be reset to the factory defaults; therefore, you MUST reconfigure those rules.

Step 2: Creating Bandwidth Object

Navigate to the Manage > Policies > Objects > Bandwidth Objects page, on top click Add button.
On the General tab

• Name: per-ip limitation (Type any Friendly Name)
• Guaranteed Bandwidth: 0 kbps (Type the required value which should be given out of total bandwidth)
• Maximum Bandwidth: 5 Mbps (Type the maximum value which can be given in more bandwidth available)
• Traffic Priority: 0 Realtime (Select priority out of eight default queue)
• Violation Action: Delay (Either select Delay or Drop for the traffic violating this bandwidth).

Click the Elemental tab

• Select Enable Per-IP Bandwidth Management
• Maximum Bandwidth: 1 Mbps (enter the maximum elemental bandwidth that can be allocated to a protocol under the parent traffic class)
• Click OK button to create the bandwidth object

Note : The maximum elemental bandwidth can't be greater than its parent class.

Step 3: Creating access rule with Bandwidth Management

• Navigate to Manage > Policies > Rules > Access Rule page.
• Select the Matrix in the View Style section and go to LAN to WAN access rules.
• Click the Edit button of the default rule on the right side.
• Click the BWM tab.

• Select "Enable Egress Bandwidth Management ('Allow' rules only)"
   Bandwidth Object: per-ip limitation (Select the bandwidth object which you created)

• Select "Enable Ingress Bandwidth Management ('Allow' rules only)"
   Bandwidth Object: per-ip limitation (Select the bandwidth object which you created)

• Click OK button to create access rule with bandwidth management.

The access rule will have the bandwidth icon in it with status information


Step 4: Test on the client PC

FTP or other download tools could be used to test the download and upload speed, which should be less than 1Mbps per IP in this case. Here a speed test website was used on the client PC to verify the Bandwidth Management.
