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.

After 3/4 of a year waiting 10.8.3 arrived...............



After a flurry of posts within the thread, Well I got my WB Black ML 10.8.2 HDD out of 'deep storage' and installed 10.8.3 Combo update, instead of messing with my production 10.7.5 Lion SSD RAID.😮


After restart network link dead.😕


So I deleted the bonded Ethernet 1 & 2 NIC's, made a new bond and all good.😉


Went for a restart, after which network link dead.😕


Again I deleted the bonded Ethernet 1 & 2 NIC's, made a new bond and all good.😉


This time I simply shutdown, waited a few minutes, hit the power button, booted, then logged in and guess what.....network link dead.😢



So a question or two for the thread posters whom appear to have been successful.




1) Did you clean install ML then install the 10.8.3 update. ?


2) Did you install the 10.8.3 update or 10.8.3 Combo update. ?


3) Did you do anything other than simply install either of the 10.8.3 update packages. ?


4) Did you use Fairy Dust, Voodoo, Chanting or others means to get Network Aggregation working. ?



Thanks

So for those of you still having problems...


We've had two issues open with Apple Engineering that related to the link aggregate connection. The first one was for it not keeping the connection after reboot, which has been fixed (after many escalations) in the 10.8.3 update released yesterday. The other issue we have open is for the server app not recognizing certain bonded connections, this is an issue with the sever app and not the OS. They are hoping to have this fixed in the next app update as they've identified the issue and confirmed it with what we've seen.


Just no update on when the next version will be released.
