Configuring A Link Aggregation Group; Configuring Vlans - Brocade Communications Systems 8 Administrator's Manual

Configuring a link aggregation group

FCoE ports can be grouped to create a link aggregation group (LAG). The LAG is treated as a single
interface.
Use the following procedure to configure a LAG.
1. Select the CEE Interfaces tab on the Switch Administration panel.
2. Select the Link Aggregation tab.
3. Click Add.
4. Select the Mode.
5. Select the Type.
6. Select the Interface Mode.
7.
8. Select the operational Status.
9. Click OK.

Configuring VLANs

The Virtual LAN (VLAN) capability allows multiple virtual LANs within a single physical LAN
infrastructure. The physical interface must be configured as L2 prior to configuring a VLAN, either
as an individual interface, or as a LAG. Before you start the VLAN configuration procedure, you
need to know which interfaces or LAGs you want to associate with each VLAN.

The Add LAG Configuration dialog box displays.
NOTE
Only ports that you defined with an Interface Mode of None can be a LAG Member.
The choices are Static and Dynamic. Static mode does not use Link Aggregation Control
Protocol (LACP) to negotiate and manage link aggregation. Link participation in the LAG is
determined by the link's operational status and administrative state. Dynamic mode uses
LACP. LACP allows partner systems to examine the attributes of the links that connect them
and dynamically form a LAG. When you select Dynamic mode, the Active and Passive options
are enabled:
•
If you choose Active, your switch initiates an exchange of LACP data units.
•
If you choose Passive, your switch waits to receive LACP data units from its partner system
and then respond. Passive is the default behavior.
Type refers to the type of trunking used by the LAG. The choices are Standard and Brocade.
The options are None and L2. The default is None.
Select the L2 Mode.
The L2 mode setting determines operation within a VLAN:
-
Access mode allows only one VLAN association, and all frames are untagged.
-
Trunk mode allows more than one VLAN association, and allows tagged frames.
The choices are Administratively Up and Administratively Down.
