I agree but the MetroLinq, for example, can't do 9k frames. At least 
they told me it doesn't when I asked since it wasn't on the datasheet.

Hi,

Just to be official about is, all airFIber radios support
transport of Jumbo packets sizes of 9000+ bytes. The currently
supported packet size is 9600. There is no configuration required
- they just do it.

I think you're thinking about this too hard, or maybe I
wasn't explicit enough. Typing from a phone causes that.

Yes, I'm staying if you are building the type of network
where you have identified a large MTU is desirable on the
L2 path, you want everything to be as high as possible,
and you will be limited by the devices smallest MTU on the
path.

Re: [AFMUG] Ben Moore, ubnt, fix your documentation of basic things!

[Eric Kuhnke]

no, it doesn't, only if you are building L2 networks bridged between
multiple locations. It's perfectly fine to have a router-to-router OSPF /30
link that is carried across a PTP system with a 1600 byte MTU (older
Bridgewave radios for instance), then another separate set of OSPF
interfaces onwards from that same router, to another router, over a 9000
byte MTU radio bridge. Or whatever.

Re: [AFMUG] Ben Moore, ubnt, fix your documentation of basic things!

MTU needs to be consistent on the entirety of the path.

AirFiber supports 9600 MTU since 1.1 FW.

Re: [AFMUG] Ben Moore, ubnt, fix your documentation of basic things!

[Sterling Jacobson]

I agree, was just looking for that a week ago too.

I’m still unclear.

My backbone is generally set for 9000+ MTU.

Do I need to change my Mikrotik Ethernet ports attached to the Air Fiber units 
to a specific MTU?

oh yeah, and there is no mention of MTU capabilities for any model of airfiber

Is that not a basic datasheet thing to list?  Particularly for PTP bridge

Now, I know this, and everyone on the list knows this, because we've been
using the AF24 for years. We know we can use it with either 1600 or 9000
byte MTU.

But I find it amazing that there is no mention anywhere of max MTU (or MTU
settings/capabilities in general) anywhere whatsoever in the ubnt AF24
users manual:

https://dl.ubnt.com/guides/airfiber/airFiber_AF24_UG.pdf
