Link aggregation issues Solaris 10

I have setup link aggregation with 3 interfaces on my solaris 10 system.

All looks good but my problem is that the traffic is only going out bge0 and not the other 2 links.

Code:
bash-4.3# dladm show-aggr -s
key:33          ipackets   rbytes       opackets   obytes       %ipkts  %opkts
        Total   2423536    169265389    693        44352
        bge0    1844204    122846897    693        44352          76.1   100.0
        bge1    289672     23209454     0          0              12.0     0.0
        bge2    289660     23209038     0          0              12.0     0.0

I tried configuring the aggregation with different levels.
L2, L3 and the default L4 but always the same.

Primeaup,

~700 packets is not a lot of traffic.

It's been a week, are you still seeing the imbalance?

Link aggregation issues Solaris 10

Good morning thanks to all for getting back to me.

I was able to get a bit more balance between the links by applying the LAC option.

Code:
-bash-4.3# dladm show-aggr -s
key:33          ipackets   rbytes       opackets   obytes       %ipkts  %opkts
        Total   11952651   926336425    9236       842048

Like this with the code tag.

If your LAN switch has active LACP enabled, then you better set LACP mode to passive and LACP timer to long:
Code:
dladm show-aggr -L
dladm modify-aggr -l passive -T long 33
dladm show-aggr -L
