Airport extreme supporting jumbo frames?

Hello,
I need to debug a problem of web site access when jumbo frames are enabled. Do you know if Airport Extreme support them? I don't know exactly the generation of the base but its serial is C86FW5NJDM72.
Regards.

The 5th generation AirPort Extreme Base Station (AEBSn) keeps the exact same revision of the mainboard (including the same SoC, 128MB of DDR2, 16MB flash, and GigE switch) as the 4th generation. What changed is that Apple designed the board to accommodate a new modular WLAN radio card. Instead of the Marvell 88W8366 WLAN of the 4th generation, the 5th generation 5 now has a dual Broadcom BCM4331-based configuration ... so the improvements would mainly be on the wireless side.

Does Airport Extreme (2010) support Jumbo Frames?

I changed my MacBookPro, my iMac27" and my NAS to Jumbo Frames (first try 9000 MTU, then 4074). But there was no faster copy speed. Now I wonder whether my switch "Airport extreme (from 2010)" is able to work with Jumbo Frames. As far as I see, on the Airport extreme there is no possibility to change the MTU.

Yes. The 2010 (actually 2009) Gigabit AirPort Extreme base station incorporates a Broadcom BCM5395 chip that supports Jumbo frames up to 9728 bytes.

Why does iMac (Mid 2012) not support Jumbo Frames?

Why is it not possible to change MTU size to more than 1500? Buying such a high quality product, I would expect that it supports jumbo frames!
My NAS supports jumbo frames, the Air Port Extreme does but a brand new iMac doesn't???
Is there any patch or somethin to fix this?
Thanks!!!

Hi Marcus,
I find conflicting info on this...
The Ethernet port supports the configuration of Ethernet frames larger than 1,500 MTU (Maximum Transmission Unit).

Can anyone confirm if the new 2011 imacs already support jumbo frames? I heard it now uses a new broadcom ethernet chip that now supports jumbo frames on the 21 inch model. They removed jumbo frames support in the previous i5 and i7 models...
Hmm, I remember that the iFix tear down revealed that the 2011 iMacs had a Broadcom BCM57765B0KMLG Eithernet chip. (just go to the page and if you are using safari/firefox press command + F and type "Broadcom" to jump to that particular)
http://www.ifixit.com/Teardown/iMac-...eardown/5485/2
so I did a little googling and found out that:
http://www.broadcom.com/products/Eth...lient/BCM57765
Integrated 10/100/1000BASE-T transceiver with:
- 10/100/1000BASE-T triple-speed MAC
- Compliant with IEEE standards
- Compliant with IEEE 802.3az draft standard for Energy Efficient Ethernet™ (EEE)
- State-of-the-art physical layer interface that exceeds IEEE requirements
- Jumbo frame support with up to 9.6 KB frame size
- EthernetAV protocols with IEEE 802.1AS, 1588-2008, IEEE P802.1Qat and IEEE P802.1Qav support
So it should support Jumbo Frames.

I set it using System Preferences -> Ethernet -> Advanced -> Ethernet -> Configure Manually.
I've confirmed the setting by checking the output of ifconfig. It shows an mtu value of 9000.

Can the AirPort Extreme support more than one printer at a time?

can the AirPort Extreme support more than one USB printer at a time if it is connected to a USB Hub?

can the AirPort Extreme support more than one USB printer at a time if it is connected to a USB Hub?
Yes.....IF.....you use a powered USB hub.
I have had 3 printers connected at the same time in the past and assume that more would work as long you have a powered hub to support the number of ports that you need.

Does the new airport extreme support backing up via time machine to an external hard drive pluged into the usb port

Does the new airport extreme support backing up via time machine to an external hard drive pluged into the usb port

Yes, but you might want to note that the port on the AirPort Extreme is only USB 2.0, and that it runs at about half the speed of the USB 2.0 port on a computer, so things are going to be quite SLOW as far as backups are concerned, or anything else for that matter.

Does the WRT310N support jumbo frames?

Greetings one and all.
Does anyone know if the WRT310N Wireless-N Gigabit Router support jumbo frames? I have a Buffalo Linkstation Mini NAS that contains a Gigabit Ethernet card. The NAS can support jumbo frames provided the switch it's connected to has the capability.
Thanks

I did a live sesion with the tech support desk
The WRT320N does have hardware support for Jumbo Frames.
Only on the Firmware (Software Side) it's not enabled yet what can easy be done by the Linksys/Cisco development team.

Does the Airport Extreme support HP cp1025? There are two versions of the printer the cp1025 and cp1025nw. I have the cp1025, and can't set it up. Is there a list of AE/bonjour supported printers?

Is there a list of AE/bonjour supported printers?

Bonjour is a transport protocol. It also provides a means of advertising a printer on a network.
Any list that shows printers that support Bonjour is generally an indication that the printer itself supports this protocol, meaning that when it is connected to the network, you can see it in your default Add Printer browser. In the case of the Airport, it also supports the Bonjour protocol and will advertise any printer that is connected to its USB port. The printer itself does not have to support Bonjour. The Airport performs this function. And like many lists, they are not kept up to date because each vendor releases several new models every quarter or half year.
There are definitely printers that don't work when connected to the USB port of the Airport. And this is more that the printer driver does not support this type of connection, mainly due to the port not supporting bidirectional communications which some printer drivers require. The Canon UFR2 and CAPT drivers are a good example of this limitation. But this is only the Mac drivers. The Windows equivalent drivers work fine when the printer is connected to the USB port.
So with you having an issue with the Windows drivers then I don't think it is a case of them not supporting Bonjour but more to do with some other component not functioning when the printer is shared by the Airport. The error message appears to have more to do with local user rights which is probably driver related. I've seen some printers that you cannot use the Windows Add Printer wizard to add them. Instead you have to use the vendors utility because of some proprietary protocol being used. Maybe this is one of those?
Now that you seen how it should work based on when you used the C3188, if you still get that error message at point 6 of adding the C1025 then it would suggest a driver compatibility issue with the Airport - which is not necessarily a Bonjour compatibility issue. So unless there was another model of HP printer driver that you could use to this C1025 and that was also compatible with the USB port of the Airport Extreme, then I would suggest your best action is to replace the printer with a model that does work. Maybe even one that has builtin wireless so you don't have to use the USB port of the Airport.

Which Macs Support Jumbo Frames?

Is there a list anywhere of which Macs support Jumbo Frames and which don't? I can tell my Mac Pro does, and my MacBook does. But sadly, my G4 does not, even though it has gigabit ethernet. Unfortunately, the G4 is my home server so it's the computer that would benefit me the most by supporting them. Just going from my mac pro to macbook, my transfer speeds jumped from 40MB to 50MB/sec. And that may have been bottlenecked by the MacBook's hard drive.

Hey l008com,
Is true

Anyway, GET IT NOW? 1504 is the limit, even though it's the built in gigabit ethernet on a dual 800 quicksilver G4.
But anyhow now that I have more info about your G4, does it have a built-in 10/100/1000BASE-T Ethernet connector and four-port 10/100BASE-T Ethernet PCI card (RJ-45 connectors)? If I'm correct about this then the gigabit port is an Uplink Port for a Hub, a Switch, another Server, Access Point or some other Network Device. I know that's not much help but the more I know about about your existing Network Setup, the less I guess about it. One thing to keep in mind is that your ISP Internet Connection is slower that 10MB/s anyway plus the their MTU's are NOT the same size and I know why.
But that really doesn't much if your Network Speed is more important than the Internet Speed.

Does Airport Extreme support Static Routes?

I have client using an Airport Extreme as their Router. They currently connect to another device outside their network using AppleTalk.
It is planned to put this device onto TCP/IP but on a different subnet (e.g. their subnet is 192.168.5.X and the device will be on say 192.168.25.X). Does Airport Extreme support (like other Routers) the ability to set up a static link to a device on a different subnet (can’t find any information in a doco or the utility) or do they need to replace this with a “real“ router?

Sure, I could do something like route add -net 10.100.10 192.168.0.100 on every client machine on the subnet, but there is no such way to configure a web cam and similiar devices
Any idea, Apple?

Does the wrt350n support jumbo frames?

Does the wrt350n support jumbo frames? Maybe in an upcoming firmware? thanks in advance

"Jumbo Frames" is a basic requirement of the Gigabit Ethernet specification. What you are saying is that the WRT350N does not actually function as a gigabit device. Sure enough it connects as one but does not transfer data at its native gigabit speed.
10Mbit connections can transfer up to around 1.2Mbytes per second.
100Mbit can transfer at around 12Mbytes per second
1000Mbit/Gigabit is supposed too transfer at up to 120Mbytes per second but cannot achieve this unless jumbo frames are active.
I beleive this gives me grounds to get a refund for a mis-sold product.
So, I guess the question needs to be re-asked.
Will the firmware ever be updated to support actual Gigabit speeds ?

Does AirPort Extreme support "loopback"?

Hi All,
My wife is has set up IIS 5.1 on a PC running Windows XP (with SP2) to serve a web page on our intranet. It seems to be set up correctly, but none of the computers on our intranet (PC or Mac) can access the page - although we can ping the server and it can ping us.
Research indicates that we need to configure the router (an Airport Extreme - the flat square type) to forward traffic on port 80 to the IIS server's IP address. This research also indicates that this will only succeed if the router supports loopback. I've done a bit of searching and have not been able to find documentation to confirm or deny whether the AirPort Extreme supports loopback.
Does it?
Thank you,
Jonathan L.
PS - The firmware on the AirPort Extreme is up to date. - J

If you could follow up with the resource you used to get that information, I'd appreciate it, but it's not essential.

Does AirPort Extreme support external drives with Advanced Format (4K) ?

Hi!
I have an AirPort Extreme from 2008 and now i want to use a Raid 1 USB HDD for Time Machine.
The new disks often has the new "Advanced Format" (4K blocks).
Does this APE support such 4k drives?
At the moment i don't have any experience with this new format,
for this reason i don't know if the APE or the hdd case has to support this format.
regards
Sebastian

1) I'm using a simple USB Disk, connected to my APE, as Time Machine Backup Volume. This works quite well for about a year.
Yes, for a few folks it does appear to work for a number of days, weeks, or months. But sooner or later, the backups turn up corrupted, often beyond repair. It happens to me about eery 3 months, which seems fairly typical. That's likely why Apple doesn't support it, and nobody should depend on it.
2) The RAID Case shows only a single disk to the connected device, raid 1 handling ist internal and so it's again just a simple usb disk.
Correct. I didn't say otherwise. In a supported location, Time Machine will back up to a hardware RAID set (but not a software one).
3) The link with the supported disks doesn't handle the new disk format 4k. :-/ Maybe the support entry is too old.
Note that it's a 2008 Airport Extreme; that predates the support article by at least a couple of years.
But by all means, call AppleCare if you don't believe the support article.

Intel mac mini support jumbo frames

Can anyone confirm if jumbo frames are supported on the Intel mac mini? In the networking control panel under Ethernet if the jumbo frames radio button is not greyed out then the hardware has support.

fabulous thanks for testing that - sounds like the intel mini is about to become a file server here!

Yes it does.

Does the e2000 wireless router support jumbo frames?

I can't find (unless I missed it) and reference in the e2000 documentation on how to set frame sizes. Is that supported? If so, what are the steps?
Solved!
Go to Solution.

An important fact is jumbo frames are not supported at speeds less than 1000 Mbps
I think Linksys E2000 already has Gigabit Ethernet ports.
And i think you can change the frame size on the Ethernet adapter properties if the adapter is Gigabit Ethernet adapter.
