Layer 3 Switch 
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
