Creating an Link Aggregation: [ http://en.wikipedia.org/wiki/Link_aggregation ]
Link aggregation, or IEEE 802.3ad, is a term which describes using multiple Ethernet network cables/ports in parallel to increase the link speed beyond the limits of any one single cable or port, and to increase the redundancy for higher availability. Here is the syntax to create aggr using dladm. You can use any number of data-link interfaces to create an aggr.
unixfoo-solaris # dladm create-aggr -l passive -d e1000g0 -d e1000g1 -d e1000g2 1
Now this creates and aggregate called “aggr1”. You can plumb this, using “ifconfig plumb” and assign IP address to it. The Link aggregation must be configured on the network switch also. The policy and and aggregated interfaces must configured identically on the other end of the ethernet cables . The example creates Link Aggregation Control Protocol (LACP) in passive mode to control simultaneous transmission on multiple interfaces. Any single stream is transmitted completely on an individual interface, but multiple simultaneous streams can be active across all interfaces.
Check properties of an aggr:
unixfoo-solaris # dladm show-aggr
key: 1 (0x0001) policy: L4 address: XX:XX:XX:XX:XX (auto)
device address speed duplex link state
e1000g0 XX:XX:XX:XX:XX 0 Mbps half unknown standby
e1000g1 <unknown> 0 Mbps half unknown standby
e1000g2 <unknown> 0 Mbps half unknown standby

To check statistics of aggr or data-link interfaces:
Use “-s” flag on show-aggr or show-link to see the statistics.
unixfoo-solaris # dladm show-aggr -s
key: 1 ipackets rbytes opackets obytes %ipkts %opkts
Total 0 0 0 0
e1000g0 0 0 0 0 – –
e1000g1 0 0 0 0 – –

To remove an interface from an link aggregate:
unixfoo-solaris # dladm remove-aggr -d e1000g2 1
unixfoo-solaris #
To delete an aggregate:
unixfoo-solaris # dladm delete-aggr 1
unixfoo-solaris #
