Configuring the Core for Jumbo Frames
If your network infrastructure supports jumbo frames, Riverbed recommends configuring the connection between the Core and the storage system as described here.
In addition to configuring Core for jumbo frames, you must also configure the storage system, as well as any switches, routers, or other network devices between the Core and the storage system.
To configure the Core for jumbo frames
1. Log in to the SteelFusion Core Management Console.
2. Choose Configure > Networking: Management Interfaces to open the Management Interfaces page.
3. Under Primary Interface, set the configuration as follows:
–  Select the Enable Primary Interface check box.
–  Select the Specify IPv4 Address Manually option and configure appropriately.
–  For the MTU setting, specify 9000 bytes.
4. Click Apply to apply the settings to the current configuration.
5. Click Save to save your settings permanently.
