The following table describes the behavior of the DHCP Relay Agent and Option 82 in the W-IAP. Table 46: DHCP Relay and Option 82 DHCP Relay Option 82 Result 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 Disabled Disabled DHCP packet not relayed, but broadcast without the ALU-specific Option 82 string In the CLI To configure a Centralized, L2 DHCP profile: (Instant AP)(config)# ip dhcp (Instant AP)(DHCP Profile )# server-type (Instant AP)(DHCP Profile )# server-vlan (Instant AP)(DHCP Profile )# option82 alu (Instant AP)(DHCP Profile )# disable-split-tunnel (Instant AP)(DHCP Profile )# end (Instant AP)# commit apply To configure a Centralized, L3 DHCP profile: (Instant AP)(config)# ip dhcp (Instant AP)(DHCP Profile )# server-type (Instant AP)(DHCP Profile )# server-vlan (Instant AP)(DHCP Profile )# dhcp-relay (Instant AP)(DHCP Profile )# dhcp-server (Instant AP)(DHCP Profile )# vlan-ip mask (Instant AP)(DHCP Profile )# 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 VC. 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 a DHCP server is configured and if the Client IP assignment parameter for an SSID profile is set to Virtual Controller Assigned, the VC assigns the IP addresses to the WLAN or the 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 6.2.1.0-3.4.0.0 or later, manually configure the DHCP pool by following the steps described in this section. You can configure a domain name, DNS server, and DHCP server for client IP assignment using the Instant UI or the CLI. 214 | DHCP Configuration Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide
