LACP Policy - Which is best?

UNIX Solaris
1

Hello,

I have these S10 boxes with LACP using the L4 policy. Does the L4 policy create a lot more overhead as opposed to using the L2?

I'm noticing that my traffic does not seem to be very well load balanced accross the NIC's, and I am wondering if the policy I'm using has anything else to do with it?

# dladm show-aggr -s

key:1           ipackets   rbytes       opackets   obytes       %ipkts  %opkts

I think more meaningful statistics can be achieved by watching the load distribution over some time. I think this will show it over 5 minutes intervals:

dladm show-aggr -s -i 300
