Mountain Lion 802.3ad Network Link Aggregation - Mac Pro 2010

Good Day.

Since upgrading to OS X Mountain Lion I've experienced some unexpected networking issues.

Unlike others reporting in this forum that they are unable to achieve 802.3ad Network Link Aggregation, I do not have this issue.

However when I shutdown or restart the 802.3ad Network Link Aggregation (bond) is physically lost, although the settings remain.

To get the 802.3ad Network Link Aggregation link working again, first I need to delete the bond, add back each ethernet, then set up the 802.3ad Network Link Aggregation bond again, afterwhich the bond works just fine until shutdown or restart.

*I'm using a TP-LINK TL-SG3216 (JetStream L2 Managed Switch) + Cat 6 Ethernet cables. Physical setup and Switch has not changed*

This is not an ideal situation, and for the long term having to go through this procedure everyday will become tedious.

One other observations, with the 802.3ad Network Link Aggregation bond made and working, within the advance tab, the Hardware Tab is greyed out. Previously in OS X Lion this was not the case and this part of the advance tab feature could be used to set frame sizes.

Any thoughts or assistance to obtaining a 802.3ad Network Link Aggregation bond that remains after shutdown or restart would be highly welcomed.

Thanks in advance.

P.S. Apple......Thanks for OS X Mountain Lion, some nice bits, but alas needs some attention to overcome various operational issues. Our other Mac Pro's are firmly staying on OS X Lion & OS X Lion Server until Mountain Lion gets the fixes that Mac Pro community needs, especially those whom use Mac Pro to earn a living.

I assume you meant doesn't care? Lol...

We went with Ubuntu... And your absolutely right, there is no need for mac hardware. I will never purchase another enterprise product from Apple. But we are stuck with this Mac Pro server for now and running Linux server on it has worked a treat. I know most mac users like me don't like to get too technical... But it was honestly really easy to set up.

Honestly everyone you are wasting your time with OsX... And that hurts to say! We even tested windows server which worked better! Imagine that... Having to install windows on a mac to get its network connections to work...

Those oh so smug mac and pc ads look rather ridiculous now!

Another example of why as a pro user you should jump ship.... Not that this ongoing LACP issue isn't enough!

Mac Pros are not available here in Europe from next monday (Feb 18th), iMacs are still showing 6 week shipping times... ***!

We have two big projects starting and need new workstations now.... What do you do? Answers on a postcard please...

The Apple really has fallen far from the tree...

Mac Pro's currently still for sale at Apple UK Store (this morning), but agree there is an upcoming date when there'll be withdrawn from sale (due to EN ISO specification compliance issue), doesn't affect other regions outside of Europe/UK, i.e. USA.

Also you'll find quite a few Apple enterprise resellers will have them in stock. Search the net.

Failing all of that, if a reburbished Mac Pro is good for you, search out ScrumpyMacs http://www.scrumpymacs.co.uk, pretty reasonable priced outfit, apparently give good support etc etc, but i've never had anything from them personally.

Let's hope a New Mac Pro is released, oh an OS that works..............

What odds that this goes 12months unsolved? Can anyone remember another issue taking this long to fix?

How far the Apple has fallen...

Mar 1, 2013 12:06 AM in response to mart30lon

We are currently being forced onto windows workstations as pro users... We have a big project starting and with Mac Pros now unavailable here in the UK we had no option. iMacs still have 6 week waiting list... Don't really want the old tech in mac pros anyway! This is the one time Apple could break their stupid no comment policy and give us exact details of what the pro line plans are!

I for one can't trust Apple any longer... You can't relay on them if your trying to run a business!

Mar 1, 2013 12:13 AM in response to mart30lon

I agree it would be good to know whats happening with the next mac pro, but its not fair to say you can't get them in the UK anymore http://www.jigsaw24.com have good stock as do http://www.cancomuk.com

They also have new iMacs in stock

Mar 1, 2013 12:49 AM in response to Kevin Neal

Did I not say we didn't want the old tech in mac pros? It's the implication of not knowing what Apples plans are...

The IMacs available are not the 27' i7 versions we need for pro use...

Mar 1, 2013 12:52 AM in response to mart30lon

The 27' machines are still having production issues! Massive fail from Tim Cooke... Especially considering the supply chain is meant to be his forte!

I finally got Link Aggregate working with Mountain Lion 10.8.2. Previously I was seeing "invalid" in Advanced menu.

The way I got it working was enabling LACP for the aggregate port group in my switch (Cisco SG200-26). Without enabling LACP, the bonded interface on OSX wouldn't connect.

Now, does anyone know how to get static LAG working on OSX with balance-rr mode 0?

Great to hear you've got Link Aggregation to work, I guess if you've read this thread the Issue is, when you restart your MAC the Link Aggregation will be lost, that's the Issue.

Just rebooted twice. My aggregated link automatically connected each time. I guess I'm just lucky then?

You certainly do seem to have been 'Blessed', unlike most of us.

For clarity can you confirm that after a reboot you can actually TX/RX data from your MAC on local network and to internet etc (might be worth using terminal and 'nettop' command to see what packets you're actually TX/RX), and when you say 'the aggregated link automatically connected' are you referring to status at your switch or on your MAC.

I assume you're MAC is a Mac Pro 2010 and you're running OS X 10.8.2?

Inquisitor,

After each reboot, I was able to visit websites and replying to this message right now without any configuration of network. My 2x1GigE aggregated link is still intact.

I'm not using a Mac Pro. I'm using custom built system with GA-77X-UD5H board visible to System Information as iMac12,2.

I'm bonding the onboard Intel+Atheros GigE ports as my aggregated link. Yes, I'm on 10.8.2

Interesting.....

So you're on a Hackintosh using a Gigabyte mobo, not an actual MAC 😉.

All said and done fair play if it works for you, for us Apple devotee using Apple hardware, it just don't! 😠
