222 | DHCP Configuration Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide
The following table describes the behavior of the DHCP Relay Agent and Option 82 in the W-IAP.
DHCP Relay

82
Behavior
Enabled Enabled DHCP packet relayed with the ALU-specific Option 82 string
Enabled Disabled DHCP packet relayed without the ALU-specific Option 82 string
Disabled Enabled DHCP packet not relayed, but broadcast with the ALU-specific Option 82 string

In the CLI
To configure a centralized,L2 DHCP profile:
(Instant AP)(config)# ip dhcp <profile-name>
(Instant AP)(DHCP Profile <profile-name>)# server-type <centralized>
(Instant AP)(DHCP Profile <profile-name>)# server-vlan <vlan-ID>
(Instant AP)(DHCP Profile <profile-name>)# option82 alu
(Instant AP)(DHCP Profile <profile-name>)# disable-split-tunnel
(Instant AP)(DHCP Profile <profile-name>)# end
(Instant AP)# commit apply
To configure a centralized,L3 DHCP profile:
(Instant AP)(config)# ip dhcp <profile-name>
(Instant AP)(DHCP Profile <profile-name>)# server-type <centralized>
(Instant AP)(DHCP Profile <profile-name>)# server-vlan <vlan-ID>
(Instant AP)(DHCP Profile <profile-name>)# dhcp-relay
(Instant AP)(DHCP Profile <profile-name>)# dhcp-server <DHCP-relay-server>
(Instant AP)(DHCP Profile <profile-name>)# vlan-ip <DHCP IP address> mask <VLAN mask>
(Instant AP)(DHCP Profile <profile-name>)# end
(Instant AP)# commit apply
Configuring the Default DHCP Scope for Client IP Assignment
The DHCP server is a built-in server, used for networks in which clients are assigned IP address by the Virtual
Controller. You can customize the DHCP pool subnet and address range to provide simultaneous access to
more number of clients. The largest address pool supported is 2048. The default size of the IP address pool is
512.
When the DHCP server is configured and if the Client IP assignment parameter for an SSID profile is set to
Virtual Controller Assigned, the Virtual Controller assigns the IP addresses to the WLANor wired clients.
By default, the W-IAP automatically determines a suitable DHCP pool for Virtual Controller Assigned
networks.
W-IAPs typically select the 172.31.98.0/23 subnet. If the IP address of the W-IAP is within the
172.31.98.0/23 subnet, the W-IAP selects the 10.254.98.0/23 subnet. However, this mechanism does not
guarantee that it would avoid all possible conflicts with the wired network. If your wired network uses either
172.31.98.0/23 or 10.254.98.0/23, and you experience problems with the Virtual Controller Assigned
networks after upgrading to Dell Networking W-Series Instant 6.2.1.0-3.4 or later, manually configure the
DHCP pool by following the steps described in this section.
