2.Plumb up the interface aggrkey, which is aggr33 is this case:

#ifconfig aggr33 plumb

#ifconfig aggr33

aggr33: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 8 inet 0.0.0.0 netmask 0

ether 0:3:ba:d8:9d:e8

#ifconfig aggr33 192.168.1.1/24 broadcast + up

#ifconfig aggr33

aggr33: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 8 inet 192.168.1.1 netmask ffffff00 broadcast 192.168.1.255

ether 0:3:ba:d8:9d:e8

3. Show link-aggregation status again, and now the state should become attached:

# dladm	show-aggr
key: 33	(0x0021)	policy: L4	address: 0:3:ba:d8:9d:e8 (auto)
	device	address	speed		duplex	link	state
	nxge0	0:3:ba:d8:9d:e8	10000	Mbps	full	up	attached
	nxge1	0:3:ba:d8:9d:e9	10000	Mbps	full	up	attached

4. Use the dladm show-aggr-scommand to display statistics:

# dladm show-aggr -s
key: 33	ipackets	rbytes	opackets	obytes	%ipkts	%opkts
Total	0	0	16	1182
nxge0	0	0	16	1182	-	100.0
nxge1	0	0	0	0	-	0.0
