Should i enable jumbo frames

Likely because, again, this depends on specific situations. But the following is often true in my experience:. Unfortunately, what MTU value to use depends on the situation. Other times you need to disable it.

There are just too many variables. Generally, which MTU value is the best depends on the receiving end — the one we typically have no control over. You want to make sure the packet size is the best for the receiver. Use Spotlight for Terminal on a Mac. The command means: Send that remote device a packet of this size and see how it replies. And via the way it responds, we can determine the best packet size MTU value. We need to lower it, so I tried again with :.

I increased it to with this command:. Still, no data loss — the optimal is now either or higher. I tried:. By the way, this is the optimal MTU value for most websites. The example above only shows you how to use the ping command to determine this value.

To figure out the best MTU value for any remote party, you need to replace dongnows. Not to be confused with the default gateway address of your router, which is for the LAN side. The idea is here is this: Handling MTU values can be a bit of work, and it requires at least a basic understanding of MTU itself, which you now have. In any case, if you want to mess with these, keep in mind that networking is a field of constant flux and fluctuations. There is no harm changing all frames to Jumbo frame by setting MTU to Change it to for all ports, observe for couple of days.

I don't think this change will do a major issue on network. It depends on your traffic profile. BTW my secondary DC is on this switch as well If I'm not mistaking you can also upgrade your MTU from the default but can't just remember if its to so that you may check up on.

You should only use jumbos on a network where all hosts using the same MTU or your asking for trouble processing the packets.

To continue this discussion, please ask a new question. As far as I've seen, all recently 1Gbps devices support jumbo frames, but Wi-Fi devices do not. Add a comment. Active Oldest Votes. Improve this answer. Ram: True. I'll extend my answer a bit. I have a small ioMega NAS box that actually gets almost double the throughput using jumbo frames, but that's because the large frames allow more data transfer with lower CPU utilization it has a low-end ARM-compatible cpu — Chris Thompson.

Rushino: Yes of course. Spectator Spectator Both of you are probably right. Some setups will allow jumbo packets to be fragmented. Some others will not.

Here's what Jeff Atwood had to say on the matter: codinghorror. Anyway, there's nothing wrong in just trying. If it doesn't work, well, it doesn't work. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
