Adding a LAG
Link aggregation, based on the IEEE 802.3ad protocol, is a mechanism to bundle several physical
ports together to form a single logical channel or trunk. The collection of ports is called a link
aggregation group (LAG).
NOTE
An internal port cannot be part of a LAG. You can create LAGs with external ports only.
•
The Add LAG button on the DCB Configuration dialog box is enabled when a single DCB switch
or ports of a single DCB switch are selected.
•
The Add LAG button is disabled when multiple switches are selected, ports from different
switches are selected, or LAGs are selected.
•
The Edit LAG button is enabled when a single LAG, port, or switch is selected.
NOTE
When LLDP-DCBX is disabled on the switch, a yellow banner displays on the DCB Configuration
dialog box, indicating that LLDP-DCBX is not only disabled on the switch, but is also disabled for all
ports and LAGs on the switch.
1. Select Configure > DCB.
The DCB Configuration dialog box displays, showing the status of all DCB-related hardware and
functions.
2. Select the DCB switch or one or more DCB ports from the Products/Ports list to add to a link
aggregation group (LAG).
3. Click Add LAG or Edit LAG.
The Add LAG or Edit LAG dialog box displays, as shown in Figure 234 .
