> # Disabling Bandwidth Fairness

> ## Restrictions

> - If you disable bandwidth fairness, up to a 20 percent increase in internal bandwidth allocation is possible for each port group; however, bandwidth fairness is not guaranteed when there is a mix of shared and full-rate ports in the same port group.

> ## Detailed Steps

> To disable bandwidth fairness on multiple 48-port or 24-port 4-Gbps, or 8-Gbps Fibre Channel switching modules using DCNM-SAN, follow these steps:

> 1. Choose Switches > Hardware.
> 2. Click the Module Config tab. You see the Module Config dialog box.
> 3. From the BandwidthFairness Admin drop-down list, select disable for each module for which you want to disable bandwidth fairness.
> 4. Click Apply to save the changes.

> To disable bandwidth fairness on a single 48-port or 24-port 4-Gbps, or 8-Gbps Fibre Channel switching module using Device Manager, follow these steps:

> 1. Right-click a module and select Configure.

> You see the Module dialog box.

> 2. Click the disable radio button to disable bandwidth fairness.
> 3. Click Apply to save the changes.
