DHCP mode of IP addressing is not supported for configuring jumbo frames. This particular system interface needs to configured with static mode of IP address. Configure MTU-override on the system internal interface to support jumbo frames is possible. In all other situations, the effort of configuring jumbo frames everywhere on your network is not worth the marginal improvement, and has the potential of slowing down or breaking non-jumbo frame clients. By default, FortiSwitch internal interface is configured with MTU size 1500. A good example of this approach is a separate SAN or storage network.

Use jumbo frames only when you have a dedicated network or VLAN, and you can configure an MTU of 9000 on all equipment, to increase performance.

For example, to determine if you can pass 7000 byte jumbo frames from your PC to a device at 192.168.1. With a Linux PC, test jumbo frame capability by typing ping -s (frame size) (destination) at the command line.

If this change is not coordinated, your network might actually run slower, or break. If you’re playing along at home with a Windows PC, test jumbo frame capability by typing ping -f -l (frame size) (destination) at the command line. If you increase the MTU on one of your end devices, your switch needs to be able to pass these larger frames (same frame size or larger, than default MTU), and the receiving end needs to handle these larger frames as well. In modern equipment, this optimization is becoming less of a problem due to LSO/LRO and TCP offload engines, especially on higher end server grade NICs.Īll equipment on the same layer 2 network, which means the same LAN or VLAN, should support the same frame size. If most of your local network devices and applications can be configured for the same jumbo frame size, your network might benefit from larger packets, less fragmentation, and less overhead. Making casual changes to MTU to optimize performance is likely to have the opposite effect of decreasing performance. Performance problems arise when the MTU of one device is different from the MTU of another. Transmitting a larger frame is more efficient, because the overhead-to-data ratio is improved. I have just acquired a Synology DS414 NAS and have enabled jumbo frame support on it, but cannot get it to work through the. The header contains no user data, and is overhead. An Ethernet packet larger than 1500 bytes is called a jumbo frame.Īn Ethernet frame uses a fixed-size header. Historically, Ethernet has a maximum frame size of 1500 bytes. When a network device gets a frame that is larger than its MTU, the data is either fragmented into smaller frames, or dropped. The maximum size of frames is called the Maximum Transmission Unit (MTU). Can you tell me if my understanding of the following is correct, If I were to have: Gigabit switch WITH jumbo frames support, connected to: A - Computer with Gigabit Jumbo frames enabled B - Computer at 100mb no Jumbo. Ethernet traffic moves in units called frames. Re: Jumbo frames, I just found that Need-to-Know article before you replied, sorry I didn't see it earlier, I have read it now.
