# Setting Up Jumbo Frames in Microsoft* Windows*

| NOTE: Jumbo frames are not supported in multi-vendor team configurations.

1. Open Microsoft* Windows* Device Manager.

2. Open Properties on your adapter.

3. Click the Advanced tab.

4. Select Jumbo Frames from the list of advanced features.

5. Set your desired packet size (based on network capability).

6. Click OK to apply the changes.

All equipment on the network must also support the larger frame size. When setting up Jumbo Frames on other network devices, be aware that different network devices calculate Jumbo Frame size differently. Some devices include the header information in the frame size while others do not. Intel adapters do not include header information in the frame size. When configuring Jumbo Frames on a switch, set the frame size four bytes higher for CRC, plus four bytes if you are using VLANs or QoS packet tagging.
