2.2.1.2 Centralized
Campus
A second architectural option is to centralize the security switches within a data center
environment. The model most suited for this role is the WSS 2380, which has four gigabit
interfaces, no PoE ports, and supports up to 120 active APs. Each AP is powered at the edge by
a PoE switch or a PoE injector, and has a DAP connection back to the central WSS 2300s.

There are a number of advantages to centralization. Among them are the traditional benefits of
centralization, such as reduced numbers of manageable assets, lower operation costs, and
design simplicity. Within the context of the WLAN, there are additional benefits, such as simplified
security implementation (for example, fewer firewalls to deploy), simplified VLAN structure, and
simplified client management. With this architecture, you can also better leverage many other
Nortel core network features, such as Split MultiLink Trunking (SMLT) to a Nortel Switch Cluster
Core, and N-1 active-active resiliency capabilities.
