DWS-1008 User's Manual
The following sections list the configuration requirements for direct attached APs and
Distributed APs.
Local Connection Requirements
When an AP connects directly to a switch's 10/100 port, the switch's port must be configured
as a DWL-8220AP access port, which supports AP traffic only. There is no intermediate
networking equipment between the switch and AP and only one AP is connected to the
switch port. The switch's 10/100 port provides PoE to the AP. The switch forwards data only
to and from the configured AP on that port.
Distributed AP Network Requirements
When an AP connects indirectly to a switch, the switch must be configured with a Distributed
AP configuration. The switch can communicate with the Distributed AP through any network
port. (In the CLI, a Distributed AP configuration is referred to as a DAP.)
Because distributed APs are not directly attached to a DWS-1008 switch, they require
additional support from the network in order to function.
• Power - PoE must be provided on one of the Ethernet connections to the AP. Be sure
to utilize a PoE injection device that has been tested by D-Link. Providing PoE on
both of the Ethernet connections (if the AP has two) allows for redundant PoE.
• DHCP - A Distributed AP uses TCP/IP for communication, and relies on DHCP to
obtain IP parameters. Therefore, DHCP services must be available on the subnet
that the AP is connected to. DHCP must provide the following parameters to the
AP:
Optionally, the Offer message can also contain a list of switch IP addresses or hostnames,
in the option 43 field of the DHCP message.
