    1.2. Configure the DHCP Server The wireless switch can function as a DHCP server to assign addresses to wireless (or wired) clients that connect to each AP. To configure the DHCP Server, you must configure global settings and the address pool for the clients. For this scenario, wireless clients will be assigned addresses in the range of 10.90.91.1/8 –...

    1.4. 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 10: Device Connections

    1.5. 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). 1.

    1.8.4.1. Self Healing Cell Recovery When a Managed AP is powered down, the power of its neighboring AP(s) managed by the same switch is immediately increased by 20%. Power Adjustment Mode should be Interval to see an increase in power of neighboring AP. By default, Initial Power is 100%, so decrease power of APs below 80% or less to see 20% increase before powering down one AP.
  • Page 17 To reset the AP configuration, you will need to telnet into the AP CLI and use the “factory-reset” command. As mentioned earlier, you can place the AP into “debug” mode from the switch if the AP is currently managed to gain access to the UI.

    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.
