Appendix C - DHCP Server
DHCP Server
MSS has a DHCP server that the switch uses to allocate IP addresses to the following:
• Directly connected APs
• Host connected to a new (unconfigured) switch, to configure the switch using the
Web Quick Start
DHCP service for these items is enabled by default.
Optionally, you can configure the DHCP server to also provide IP addresses to Distributed
APs and to clients.
Configuration is supported on an individual VLAN basis. When you configure the DHCP
server on a VLAN, the server can serve addresses only from the subnet that contains the
host address assigned to the VLAN. By default, the VLAN can serve any unused address in
the subnet except the VLAN’s host address and the network and broadcast addresses. You
can specify the address range.
You can configure the DHCP server on more than one VLAN. You can configure a DHCP
client and DHCP server on the same VLAN, but only the client or the server can be enabled.
The DHCP client and DHCP server cannot both be enabled on the same VLAN at the same
time.
The MSS DHCP server is implemented according to “RFC 2131: Dynamic Host Configuration
Protocol” and “RFC 2132: DHCP Options and BOOTP Vendor Extensions”, with the following
exceptions:
• If the switch is powered down or restarted, MSS does not retain address allocations
or lease times.
• The MSS DHCP server will not operate properly when another DHCP server is
present on the same subnet.
• The MSS DHCP server is configurable on an individual VLAN basis only, and
operates only on the subnets for which you configure it.
Note:
Use of the MSS DHCP server to allocate client addresses is intended for temporary,
demonstration deployments and not for production networks. D-Link recommends that you
do not use the MSS DHCP server to allocate client addresses in a production network.
