Overview
The standard small system reference design includes a Cisco 3750 L3 Switch which supports
20 Intelligent Access Points (IAPs). Four switch ports (ports 1-4) are also available for
network servers such as the One Point Wireless Manager™ server and RADIUS. IAPs are
connected to L3 switch (ports 5-24) via one of three methods:
•
Direct Ethernet
•
Connection via a wireless bridge (Motorola Canopy™ System)
•
Connection via a wireline media converter (e.g. Ethernet over Fiber media
converter)

The Cisco 3750 router provides the following services:
•
Routing between the wireless subnets 10.1.0.0 /16, 10.24.0.0/16, 10.49.0.0/16,
and the server network 172.31.0.0/16 (e.g. inter VLAN routing between VLANs
1, 24, 31, and 49).
•
DHCP relay from the wireless subnets to the DHCP server running on the One
Point Wireless server 172.31.0.20.
•
802.1Q VLAN tag recognition enabling the support of a trunked set of VLANs
terminating on a single physical interface
IP Directed Broadcasts
By default, the 3750 Switch drops IP directed broadcasts; thus preventing them from being
forwarded. The One Point Wireless Manager™ application utilizes SNMP broadcasts for
automatic network discovery. We have enabled IP directed broadcasts in the 3750 L3 switch
