  • Page 9 Rule 1 Next, you must attach the ACL to port 0/1 and port 0/13 (the physical ports to which the APs will be connected) so that the rules are applied to the appropriate wireless client traffic that goes through the APs connected to the switch. 1.

  • Page 10: Wireless Configuration

    Wireless Configuration You configure and monitor all wireless settings from the WLAN tab on the navigation panel. Since the deployment is an L2 Edge and there are no subnet boundaries to cross, the switch can use the network management IP address for the wireless functions (Note: the wireless switch component uses an IP address to manage the APs and peer-switches.

  • Page 11: Device Connections

    Device Connections At this point, all the devices are ready to be connected. After the switch discovers the APs, they will appear on the Failed list because the MAC addresses of the APs are not configured in the Valid AP database (i.e. the switch has not been configured to accept any valid APs).

    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 Wireless Switch (WS1). Since the wireless 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.
