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.
