Example: Configuring Link Aggregation with Ruckus Wireless APs


This example shows how to configure a 2-gigabit uplink between a Ruckus Wireless AP and an EX Series switch by using the link aggregation features supported on the devices.


This example uses the following hardware and software components:

  • EX3300 switch running Junos OS Release 12.3 or later

  • Ruckus Wireless Zoneflex R710 AP running version 100.2.0 or later

Overview and Topology

The tested topology uses an EX3300 Virtual Chassis connected through two Ethernet ports to a ZoneFlex R710 AP. The configuration for connecting to a standalone EX3300 is similar.

Figure 1 shows the topology used in this example.

In this example, the switch provides power to the AP through Power over Ethernet (PoE). The ZoneFlex R710 AP can operate in two PoE modes: 802.3af and (PoE+) modes. If it is operating in 802.3af mode, the second Ethernet port (eth1) is disabled. Thus, to support link aggregation, the ZoneFlex 710 AP must operate in 802.3at mode. In its default configuration, the EX3300 switch automatically uses LLDP-MED to negotiate 802.3at mode with the ZoneFlex R710 AP. No additional configuration of the switch is required to achieve this.


This section provides step-by-step instructions for:

Configuring the ZoneFlex R710 Wireless AP

Step-by-Step Procedure

To configure link aggregation on the AP, you must use the set bond command from the AP CLI. The command has the following syntax:

To create a LAG, you need only create the bond profile and add the two physical Ethernet interfaces to the LAG. The options for configuring the LACP rate and the transmit hash mechanism are optional. Note that bond0 is the only valid bond profile name.


Ensure that both Ethernet ports have been administratively enabled before starting this procedure.

To configure the AP for link aggregation:

  1. Verify that the AP power mode is 802.3at:
  2. Create the bond0 profile for the LAG group and add the two physical Ethernet interfaces to the LAG.

    When you create the LAG group, LACP is automatically enabled.

  3. (Optional) Set the transmit hashing option to Layer 3 and Layer 4 to optimize hashing for common enterprise WLAN environments.

Configuring the EX3300 Virtual Chassis

Step-by-Step Procedure

To configure the LAG on the EX3300 Virtual Chassis:

  1. At the chassis level, specify the number of aggregated Ethernet interfaces to be created on the switch.
  2. Configure LACP on aggregated Ethernet interface ae9.
  3. Specify that interface ae9 is an access interface belonging to VLAN AP-to-WLC and configure the VLAN.
  4. Add the ge-04/0/2 and ge-4/0/3 interfaces to the LAG.


From configuration mode, confirm your configuration by entering the following show commands:


Confirm that the configuration is working properly.

Verifying the LAG Configuration on the AP


Verify that the LAG configuration on the AP is correct and that the LAG is operational.


Enter the get bond command at the AP CLI.


The LAG is configured correctly and is operational.

Verifying the LAG Configuration on the Switch


Verify the state of the link between the switch and the AP and the state of LACP.


  1. Verify the link state of the aggregated Ethernet interface.
  2. Verify the state of the LACP protocol.


The aggregated Ethernet interface is operational and the LACP protocol is active between the LAG partners.
