D-Link UWS User Manual
The DWL-3600AP has one radio and is capable of broadcasting in the following wireless modes:
• IEEE
802.11b
mode
• IEEE 802.11g mode
• IEEE 802.11n mode (2.4 GHz)
The DWL-X600AP access points support up to 16 virtual access points (VAPs) per radio. The VAP feature allows
you to segment each physical access point into multiple logical access points that each support a unique SSID,
VLAN ID, and security policy.
DWS-4000 Series Switch and AP Discovery Methods
The DWS-4000 Series switch and AP can use the following methods to discover each other:
•
•
IP Address of AP Configured in the Switch
•
IP Address of Switch Configured in the AP
L2 Discovery
When the AP and DWS-4000 Series switch are directly connected or in the same layer 2 broadcast domain and
use the default VLAN settings, the DWS-4000 Series switch automatically discovers the AP through its
broadcast of a L2 discovery message. The L2 discovery works automatically when the devices are directly
connected or connected by using a layer 2 bridge.
For more information about L2 Discovery, see
“L2/VLAN Discovery” on page 546
Note:
For an AP to be managed by a switch, the managed mode on the AP must be enabled. To enable
managed mode on the AP, log on to the AP CLI and use the
set managed-mode up
command or access
the Administration Web UI and go to the Managed Access Point page and enable the Managed Mode
option.
Note:
The AP and the switch that should manage the AP cannot be separated by a Network Address
Translation (NAT) device. The AP and switch exchange each other's IP addresses in the payload of the
discovery and other messages. These addresses are then used for the subsequent communication
between the switch and the AP. As those addresses do not undergo translation, the switch and AP will
fail to communicate. However, the switch and the AP will have no such communication issues for
remote sites or branch offices that are connected by Virtual Private Network (VPN). VPN functionality
is already commonly found on firewalls. This issue can be resolved by setting up VPN access between
the networks that use NAT.
