AP Configuration This section provides information on configuration steps performed through the CLI or the UI. Table 78: W-IAP Configuration for Scenario-GRE: Single Datacenter Deployment with No Redundancy Configuration Steps CLI Commands UI Procedure 1. Configure Aruba GRE or manual GRE l Aruba GRE uses an IPSec tunnel to facilitate controller configuration and requires VPN to be configured. This VPN tunnel is not used for any client traffic. l Manual GRE uses standard GRE tunnel configuration and requires controller configuration to complete the GRE tunnel. Aruba GRE configuration (ap)(config)# vpn primary (ap)(config)# vpn gre-outside Manual GRE configuration (ap)(config)# gre primary (ap)(config)# gre type 80 Per-AP GRE tunnel configuration Optionally, per-AP GRE tunnel can also be enabled, which causes each W-IAP to form an independent GRE tunnel to the GRE endpoint. This requires each W-IAP MAC to be present in the controller whitelist if Aruba GRE is used, or GRE configuration for the IP of the each W-IAP on the controller for Manual GRE. (ap)(config)# gre per-ap-tunnel See Enabling Automatic Configuration of GRE Tunnel and Configuring an L2-GRE Tunnel NOTE: Starting with 6.4.3.1-4.2.0.0, if Virtual Controller IP is configured and per-AP GRE tunnel is disabled, W-IAP uses Virtual Controller IP as the GRE source IP. For Manual GRE, this simplifies configuration on controller, since only the Virtual Controller IP destined GRE tunnel interface configuration is required. 2. Configure routing profiles to tunnel traffic through GRE. (ap)(config)# routing-profile (ap)(routing-profile)# route 0.0.0.0 0.0.0.0 See Configuring Routing Profiles 3. Configure Enterprise DNS. The example in the next column tunnels all DNS queries to the client's original DNS server without proxying on W-IAP. (ap)(config)# internal-domains (ap)(domains)# domain-name * See Configuring Enterprise Domains 4. Configure centralized L2 DHCP profile with VLAN 20. Centralized L2 DHCP profile VLAN 20 (ap)(config)# ip dhcp l2-dhcp (ap)(DHCP profile "l2-dhcp")# server-type Centralized,L2 (ap)(DHCP profile "l2-dhcp")# server-vlan 20 See Configuring Centralized DHCP Scopes Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide IAP-VPN Deployment Scenarios | 395
