Configuring Link Aggregation in a

Solaris Environment

This section explains how to configure link aggregation in a Solaris environment.

▼To Configure Link Aggregation in a Solaris Environment

1.Aggregate nxge0 and nxge1 to form an aggregation and a random number 33 as key.

a.Unplumb the interfaces to be aggregated:

#ifconfig down unplumb nxge0

#ifconfig down unplumb nxge1

b.Create a link-aggregation group with key 33 without specifying mode:

#dladm create-aggr -d nxge0 -d nxge1 33

As the command returns, one line appears in /etc/aggregation.conf file and indicates that the default mode is off, as shown in the following example:

# tail -1 /etc/aggregation.conf
33	L4	2	nxge0/0,nxge1/0		auto	off	short
# 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	standby
	nxge1		0:3:ba:d8:9d:e9		10000	Mbps	full	up	standby
# dladm show-link aggr33
aggr33		type: non-vlan		mtu: 1500		aggregation: key 33
