4. Configure the following LAG parameters, as required:
NOTE
Ports with 802.1x authentication or ports that are enabled in L2 mode or L3 mode are not
supported in a LAG.
•
LAG ID - The LAG identifier, which is not an editable field.
•
Status - Click the Enable check box to enable the LAG. You must enable the LAG to use the
DCB functionality.
•
Interface Mode - Select None or L2. For external ports, the L3 interface mode displays, in
addition to None or L2. If you select L3 as the interface mode, the IP/Netmask field is
enabled and you can then assign the primary and secondary IP addresses.
•
A port must be in non-L2 mode if you are adding the port as a member of a LAG.
•
You cannot change the interface mode from L2 to None if the LAG is assigned to a
VLAN.
•
L2 Mode - Select Access or Trunk

Access mode allows only one VLAN and allows only untagged frames.

Trunk mode allows more than one VLAN association and allows tagged frames.
IP/Netmask - The netmask is used to divide an IP address into subnets. It specifies which
portion of the IP address represents the network and which portion represents the host,
and can only be configured if the interface mode is L3. Primary and secondary IP address
fields are applicable only to the external ports and the interface mode must be L3 to
enable these fields.

Primary - Enter the primary IP address assigned to an L3 port.

Secondary - Enter the secondary IP address (optional). Multiple (secondary) IP
addresses help when the interface and port are part of multiple subnets.
5. Continue to configure the following LAG parameters. These parameters are disabled until you
add a DCB port to the LAG Members list.
•
Mode - The ports that are LAG members are in either Static or Dynamic mode. You cannot
change the mode on existing members of a LAG.
If the mode is set as Dynamic, you can change the dynamic mode type (to Active or
Passive) only for newly-added ports, not for existing port members of a LAG.
•
Type - The type value options are Standard, where the LAG is limited to 16 ports, and
Brocade, where the LAG is limited to four ports. The default is Standard. The type is set
when you add a LAG; you cannot edit the type using the Edit LAG dialog box.
6. Click OK .
