Configuring and managing Mobility Domain roaming 221

Nortel WLAN—Security Switch 2300 Series Configuration Guide

Clearing a Mobility Domain member from a seed

You can remove individual members from the Mobility Domain on the seed WSS. To remove a specific member of the
Mobility Domain, type the following command:

clear mobility-domain member ip-addr

This command has no effect if the WSS member is not configured as part of a Mobility Domain or the current WSS is
not the seed.

Smart Mobile Virtual Controller Cluster configuration

Virtual Controller Cluster configuration terminology

Domain configuration – Wireless parameters in the configuration file, include the following:
radio profiles
service profiles
AP configuration
The Domain configuration is typically duplicated among more than one WSS in a cluster.
Configuration Cluster – The cluster subset of WSSs in a Mobility Domain that share a domain configuration.
Primary AP Manager (PAM) – The WSS in the cluster responsible for actively managing APs that receive
configuration information from the PAM.
Secondary AP Manager (SAM) – The WSS in the cluster acting as the hot standby for an AP.

Centralized configuration using Virtual Controller Cluster Mode

Cluster mode is a subset of a Mobility Domain.
After the predetermined set of configuration parameters are distributed from the primary seed to members of the
cluster in a load balanced manner, the AP parameters are distributed to the APs on each WSS.
A member of a configuration cluster does not have a local copy of the domain configuration unless it is the primary
or secondary seed.
An WSS cannot boot an AP without network connectivity to the primary or secondary seed.
The domain configuration is created and managed by the active seed.
The secondary seed provides redundancy for configuration management to the primary seed.
The primary seed takes precedence over the secondary seed if there are conflicting configurations between
them. The only exception is if you explicitly override the configuration.
Changes to the secondary seed are not allowed while the primary seed is active on the network.
You can add more WSSs to the cluster to increase AP booting capacity seamlessly. This do not require any
configuration changes to more than one WSS in the cluster.
