WFS709TP ProSafe Smart Wireless Switch Software Administration Manual
11-6 Configuring Redundancy
v1.0, June 2007
any one of the local WFS709TPs becomes unavailable, the master takes over the APs controlled
by that local WFS709TP for the time that the local WFS709TP remains unavailable. When the
local WFS709TP comes back again, it resumes control over the APs.
This type of redundant solution is illustrated by Figure 11-2.
In the network shown in Figure 11-2, the master WFS709TP is connected to the local WFS709TPs
on VLANs 1, 2… n respectively through a Layer 2 network. To configure redundancy, configure
VRRP instances on each of the VLANs between the master and the respective local WFS709TP.
The VRRP instance on the local WFS709TP is configured with a higher priority to ensure that
when it is available, the APs always choose the local WFS709TP to terminate their tunnels.
To configure the master and local WFS709TPs for such a topology:
1. Configure the interface on the master WFS709TP to be a trunk port with 1, 2… n being
member VLANs.
2. Collect the following data:
• VLAN IDs on the WFS709TP corresponding to the VLANs 1, 2…n shown in the
topology above
Note: This solution requires that the master WFS709TP have Layer 2 connectivity to all
the local WFS709TPs.
