6. Optionally define the following Cluster Settings and overrides:

7. Within the Cluster Member field, select Cluster VLAN to enable a spinner control to designate

the VLAN where cluster members are reachable. Specify a VLAN from 1 - 4094.

Specify the IP addresses of the VLAN’s cluster members using the IP Address table.

8. Select OK to save the changes and overrides made to the profile’s cluster configuration. Select

Reset to revert to the last saved configuration.

Access Point Radio Power Overrides (Access Points Only)

A profile can manage the transmit output power of the Access Point radios it supports within the
network.

Cluster Mode

A member can be in either an Active or Standby mode. All active member
controllers or service platforms can adopt Access Points. Standby members only
adopt Access Points when an active member has failed or sees an Access Point
that’s not yet adopted. The default cluster mode is Active and enabled for use
with the profile.

Cluster Name

Define a name for the cluster name unique to its configuration or profile support
requirements. The name cannot exceed 64 characters.

Master Priority

Set a priority value from 1 and 255 with the higher value being given higher
priority. This configuration is the device’s priority to become cluster master. In
cluster environment one device from cluster members is elected as cluster
master. This configuration is the device’s priority to become cluster master. The
default value is 128.

Handle STP Convergence

Select the radio button to enable Spanning Tree Protocol (STP) convergence for
the controller or service platform. In general, this protocol is enabled in layer 2
networks to prevent network looping. Spanning Tree is a network layer protocol
that ensures a loop-free topology in a mesh network of inter-connected layer 2
controller or service platform. The spanning tree protocol disables redundant
connections and uses the least costly path to maintain a connection between
any two controllers or service platforms in the network. If enabled, the network
forwards data only after STP convergence. Enabling STP convergence delays the
redundancy state machine execution until the STP convergence is completed
(the standard protocol value for STP convergence is 50 seconds). Delaying the
state machine is important to load balance APs at startup. The default setting is
disabled.

Force Configured State

Select the radio button to allow this controller or service platform to take over for
an active member if it were to fail. A standby controller or service platform in the
cluster takes over APs adopted by the failed active member. If the failed active
member were to come back up, the active member starts a timer based on the
Auto Revert Delay interval. At the expiration of the Auto Revert Delay, the standby
member releases all adopted APs and goes back to a monitoring mode. The Auto
Revert Delay timer is stopped and restarted if the active member goes down and
comes up during the Auto Revert Delay interval. The default value is disabled.

Force Configured State
Delay

Specify a delay interval in minutes (1 - 1,800). This is the interval a standby
member waits before releasing adopted APs and goes back to a monitoring
mode when an active cluster member becomes active again after a failure. The
default interval is 5 minutes.
