Chapter 3 Configuring Ports and Interfaces

Enabling Link Aggregation

• If the recommended load-balancing method cannot be configured on the Catalyst switch, then

configure the LAG connection as a single member link or disable LAG on the controller.

Figure 3-13 Link Aggregation with Catalyst 6500 Neighbor Switch

Link Aggregation Guidelines

Keep these guidelines in mind when using LAG:

• You cannot configure the controller’s ports into separate LAG groups. Only one LAG group is

supported per controller. Therefore, you can connect a controller in LAG mode to only one neighbor

device.

Note The two internal Gigabit ports on the controller within the Catalyst 3750G Integrated

Wireless LAN Controller Switch are always assigned to the same LAG group.

• When you enable LAG or make any changes to the LAG configuration, you must immediately reboot

the controller.

• When you enable LAG, you can configure only one AP-manager interface because only one logical

port is needed. LAG removes the requirement for supporting multiple AP-manager interfaces.

• When you enable LAG, all dynamic AP-manager interfaces and untagged interfaces are deleted, and

all WLANs are disabled and mapped to the management interface. Also, the management, static

AP-manager, and VLAN-tagged dynamic interfaces are moved to the LAG port.

• Multiple untagged interfaces to the same port are not allowed.

• When you enable LAG, you cannot create interfaces with a primary port other than 29.

• When you enable LAG, all ports participate in LAG by default. Therefore, you must configure LAG

for all of the connected ports in the neighbor switch.
