Editing a LAG
17
5. Configure the following LAG parameters:
NOTE
Ports with 802.1x authentication or ports that are L2/L3 mode enabled are not supported in a
LAG.
• Status - Enabled or Disabled. You must enable the LAG to use the CEE functionality.
• LAG ID - The LAG identifier, which is not an editable field.
• Interface Mode - L2 or none. 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 the L2 mode (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.
• Primary - Enter the primary IP address assigned to an L3 port.
NOTE
Primary and secondary IP fields are applicable only to the external ports and the interface
mode must be L3 to enable these fields.
• Secondary - Enter the secondary IP address (optional). Multiple (secondary) IP addresses
help when the interface and port are part of multiple subnets.
6. Select at least one available CEE port from the Available Members table and click the right
arrow button to move them to the LAG Members table.
The CEE ports are now part of the link aggregation group.
7. Continue to configure the following LAG parameters. These parameters are disabled until you
add a CEE port to the LAG members table.
• 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.
8. Click OK when you have finished modifying the LAG parameters.
The CEE Confirmation and Status dialog box displays.
9. Review the changes carefully before you accept them.
10. Click Start to apply the changes, or click Close to abort the operation.
NOTE
If the primary or secondary IP address already exists on another interface, an error message
displays in the Status area.
