WFS709TP ProSafe Smart Wireless Switch Software Administration Manual
Configuring Redundancy 11-5
v1.0, June 2007
3. Enter the parameters shown in Table 11-1. For this topology, the following values are
recommended:
• Priority: Set the “initially preferred” master to 110 and set the backup master to 100.
• Enable pre-emption.
• Configure master up time or master state tracking with an add value of 20.
4. Configure the values in the respective fields, then click Done to enter the values.
5. Click Apply to apply the configuration and add the VRRP instance.
6. Associate the VRRP instance with the master WFS709TP redundancy (see Table 11-2).
7. Configure the APs to terminate their tunnels on the Virtual IP address. See “Configuring APs”
on page 10-3.
The master IP address is configured for local WFS709TPs during the initial setup of the switch.
You can also change the master IP address configured on the local WFS709TP in the
Configuration > Advanced > Switch > General page in the browser interface.
The WFS709TP requires a reboot after you change the master IP of the WFS709TP.
If Domain Name Service (DNS) resolution is the chosen mechanism for the APs to discover their
master WFS709TP, ensure that the name “netgear-master” resolves to the same VIP address
configured as a part of the master redundancy.
Master-Local WFS709TP Redundancy
This section outlines the concepts behind a redundancy solution where a master can act as a
backup for one or more local WFS709TPs, and shows how to configure the WFS709TPs for such
a redundant solution. In this solution, the local WFS709TPs act as the switches for the APs. When
