| Jumbo Frames | Jumbo frames improve network performance. You must have a 1 |
|
| Gbps (Gigabit Ethernet) network that supports jumbo frames. Select |
|
| the largest size of frame that all of your network devices (including |
|
| computer Ethernet cards and switches, hubs, or routers) support. |
|
| When enabled, you can choose between 4 KB, 8 KB, and 9 KB frame |
|
| sizes. |
|
| Note: If you enable jumbo frames on the NSA in a network that |
|
| does not support them, you will lose access to the NSA. If |
|
| this occurs, you will have to restore the factory default |
|
| configuration. Push the RESET button on the NSA’s rear |
