I'm having trouble getting my server to spread the transmit data over an
aggregated link (Sun Fire X2250) create from its two on-board
interfaces. Below is the configuration of the aggregation:
# dladm show-aggr
LINK POLICY ADDRPOLICY LACPACTIVITY LACPTIMER
FLAGS
aggr1 L2,L3,L4 auto active short
-----
# dladm show-aggr -x aggr1
LINK PORT SPEED DUPLEX STATE ADDRESS
PORTSTATE
aggr1 -- 1000Mb full up 0:23:8b:ce:45:c2 --
e1000g0 1000Mb full up 0:23:8b:ce:45:c2
attached
e1000g1 1000Mb full up 0:23:8b:ce:45:c3
attached
The other end is an Extreme Network X450a switch stack and everything is
configured correctly on its end of the link aggregation. I'm streaming
video over this link to a few dozen clients over UDP and given the
transmit policy, I should see at least some transmit utilization on
either link. However, for some reason, the system doesn't load-balance
at all, instead sending almost all (99.9%) though e1000g0.
Can somebody please help me find out why the server is sending
everything through the first link and ignoring the second? The switch is
also streaming some data back to me and there I can see a near perfect
50-50% split of the transmit data, so the link appears to be configured
fine...
Regards,
