===== Show Info =====

Show existing **physical interface and link information**:

<file>
dladm show-phys
dladm show-link
dladm show-ether
dladm show-aggr
</file>

Show existing **IP configuration** and delete:

<file>
ipadm show-if
ipadm delete-if e1000g0
</file>

**Create the bond** specifying the interfaces to include and add a static IP address:

<file>
dladm create-aggr -l e1000g0 -l e1000g1 aggr0
ipadm create-addr -T static -a 192.168.1.100/24 aggr0/v4
</file>

**Delete a bond**:

<file>
ipadm delete-if aggr0
dladm delete-aggr aggr0
</file>

FIXME Add LACP bonding to switch that supports LACP.

:!: If you are using the bond to communicate with the server, you will **lose connectivity** on the next step.

**Enable LACP** on the server side:

<file>
dladm modify-aggr -L active -T long aggr0
</file>

**Add interfaces to a bond**:

<file>
dladm add-aggr -d e1000g1 -d e1000g3 aggr1
</file>

**Show routes**:

<file>
netstat -nr
</file>

**Add a route**:

Ephemeral:

<file>
route add default <ipaddress>
</file>

Persistent:

<file>
echo <ipaddress> > /etc/defaultrouter
</file>
