Manage Stacking and Redundancy

ProSAFE Wireless Controller WC9500
Stacking allows wireless clients to roam from an access point that is managed by one of the
controllers in the stacking group to any access point managed by the other controllers in the
same stacking group.
The master and slave controllers in a stack support the following capacities:
• Master controller. You can perform the following tasks:
- Manage the slave controllers
- Perform RF planning for the slave controllers
- Configure the entire network, including access point discovery and license
reinforcement
- Monitor the entire network
- Push new a firmware image to the slave controllers
• Slave controller.
Y
ou can perform the following tasks:
- Access the master controller’
s web management interface (all controllers share the
same administrative user name and password)
- Configure the subnetwork
- Monitor the subnetwork
- Upgrade the firmware image on the slave controller only
- Perform access point discovery for the subnetwork
- Reinforce licenses for the subnetwork
Note: A single wireless controller that does not function in a stack can
manage up to 300 access point; a single wireless controller in a stack
can manage up to 200 access points.
If a wireless controller does not function in a stack and manages more
than 200 access points and you add the wireless controller to a stack,
all access points are removed from its managed list.
The access
points are removed because of the reduction in maximum capacity
from 300 to 200 access points.
You must let the wireless controllers in the stack rediscover the
access points and add them to the managed lists of several wireless
controllers in the stack.
