Recommended AP configuration settings CLI Commands Required Settings Default Settings Description Max-clients 40 0 Max clients that can associate with the AP. Beacon-interval Set to default 100 milliseconds The interval at which beacons are sent out . dtim-period 3 1 Delivery Traffic Indication Message interval in terms of beacon interval. hide-essid Enable Disable To disable the ESSID from being broadcasted. Max-retries 2 4 Maximum number of times the AP tries to send a packet to the client before discarding the packet. b/g-mode Mixed Mixed The radio mode of the b/g radio. Tx-power <0-4> 0 As per the environment. This need not be set if ARM is enabled. Channel 1 This is the channel assigned to the radio. Need not be set if ARM is enabled. 802.11b/g rates These rates should be determined from RF site survey.

Short preamble Tested: Enable Recommended: Disable Enable Set the short preamble to disable, to enable longpreamble- only support. PN: 1725-36080-001_J.doc Aruba Mobility Controllers: A200, A800, A2400, A6000 CLI command configuration All of the commands listed in the CLI Commands column above must be entered under the ap location command. The format is: ap location x.y.z phy-type g (To make the changes for the “g” radio.) commands ! phy-type a (To make the changes for the “a” radio.) commands ! Web-based configuration 1. Click the Configuration button. 2. In the navigation pane, select Radio from the WLAN sub-menu. 3. Click the 802.11b/g tab. 4. For Max Retries, enter 2 for voice. 5. Select the Short Preamble check box. 6. For the DTIM period, enter 3. 7. For Basic Rates and Supported Rates, consult the facility’s RF site survey to determine if coverage is sufficient to support all data rates. 8. To assign the power and channel setting manually: a. For ARM Assignment, select Disabled. b. Clear the ARM Scanning check box. c. Set the Default Channel and Initial Transmit Power from their drop- down lists. d. For Mode, click the Access-point option. 9. Click the Apply button. PN: 1725-36080-001_J.doc Configuration Guide PN: 1725-36080-001_J.doc Aruba Mobility Controllers: A200, A800, A2400, A6000 10.

PN: 1725-36080-001_J.doc Configuration Guide Dynamic RF Management — ARM Aware Scanning If Adaptive Radio Resource Management (ARM) Aware Scanning (RF scanning) is included in your firmware release, it can be enabled through the command line interface as follows: configure terminal ap location x.y.z phy-type g arm scanning enable arm assignment single-band arm voip-aware-scan enable phy-type a arm scanning enable arm assignment single-band arm voip-aware-scan enable write mem This feature was enabled during VIEW Certification testing in a screen room (strong signals in a clean environment). A real-world test with interfering RF signals was not simulated. PN: 1725-36080-001_J.doc Aruba Mobility Controllers: A200, A800, A2400, A6000 Security Policies and QoS Once the basic infrastructure is configured, it is necessary to configure the security policies to ensure that the data network and the voice network are secured and access to these networks is limited as required. The steps are as follows: 1. Setup aliases for the SVP Server. 2. Set policies for the wireless telephone user to the required voice server, DHCP and TFTP servers. Add other ACLs as required...
