2. Scenario 2 – L2/L3 Edge: 1 Unified Switch + 2 AP
The diagram in this section shows a L2/L3 edge/overlay setup. In this scenario, a Unified Switch
acts as an L3 device. Although the two APs are directly connected to the switch, they are in
different subnets. Both the APs are managed by the D-LINK Unified Switch. Since the Unified
Switch supports VLAN routing, L2 paths can be established between the AP switch ports
although they are on different IP subnets such that L3 Tunneling is not required.
This scenario has the following objectives:
• Understand how to implement a real plug & play deployment.
• Configure VLAN routing interfaces to simulate a L3 network with multiple subnets.
• Create an ACL to block IP traffic between clients on different SSIDs.
• Assign IP addresses of APs & wireless clients through the Unified Switch DHCP server.
• Configure multiple SSIDs with different VLANs.
• Enable wireless encryption.
An overview of the configuration steps needed to complete this scenario is as follows:
1. Configure VLANs
2. Configure VLAN routing interfaces
3. Enable routing
4. Create loopback interface for WLAN functions
5. Set up DHCP server and address pools for VLANs
6. Configure ACL
7. Configure the AP profile, including new SSIDs and security
8. Add VLANs to L2 discovery list
9. Attach, discover, and validate APs
10. Save configuration
