How to Add a Link to an Aggregation

1. Assume the System Administrator role or become superuser.

   The System Administrator role includes the Network Management profile. To create the role and assign the role to a user, see Chapter 9, Using Role-Based Access Control (Tasks), in System Administration Guide: Security Services.

2. Ensure that the link you want to add has no IP interface that is plumbed over the link.

   # ifconfig interface unplumb

3. Add the link to the aggregation.

   # dladm add-aggr -l link [-l link] [...] aggr

   where link represents a data link that you are adding to the aggregation.

4. Perform other tasks to modify the entire link aggregation configuration after more data links are added.

   For example, in the case of a configuration that is illustrated in Figure 6–3, you might need to add or modify cable connections and reconfigure switches to accommodate the additional data links. Refer to the switch documentation to perform any reconfiguration tasks on the switch.

Example 6–3 Adding a Link to an Aggregation

This example shows how to add a link to the aggregation video0.

# dladm show-link
LINK          CLASS     MTU     STATE     OVER
subvideo0     phys      1500    up        ----
subvideo1     phys      1500    up        ----
video0        aggr      1500    up        subvideo0, subvideo1
net3          phys      1500    unknown   ----

# dladm add-aggr -l net3 video0
# dladm show-link
LINK          CLASS     MTU     STATE     OVER
subvideo0     phys      1500    up        ----
subvideo1     phys      1500    up        ----
video0        aggr      1500    up        subvideo0, subvideo1, net3
net3          phys      1500    up        ----
