Configuring Group Settings for Wireless

Aruba Central uses a two-level hierarchy for configuration tasks. A device’s final configuration is a result of configuration that is applied at the group level, along with configuration that is applied at a device level. Parameters added at the device level override the configuration performed at the group level. Aruba recommends performing the bulk of the configuration at the group level and only using device-level configurations when specific overrides are needed.

Configure AP Group Settings

Use this procedure to configure group settings for APs. An AP Group guarantees common settings are consistently applied across a group of APs in the network.

NOTE:
The best practice is to use the fewest groups necessary to provide logical organization for the network and consistent configuration between devices. Configuration cannot be shared between groups.

Step 1 Navigate to Central and login using administrator credentials.

Step 2 On the Aruba Central Account Home page, launch the Network Operations app.

Step 3 In the filter drop-down list, select an AOS10 Group name. In this example, select UI-WIRELESS.

Step 4 From the left menu, select Devices.

Step 5 In the upper right of the Access Points page, select Config, and then select Show Advanced.

Step 6 On the Access Points page, select the System tab.

Step 7 On the System tab, implement the following settings, and then select Save Settings.

  • Set Country code for group: US - United States
  • Timezone: Pacific-Time UTC-08
  • Preferred Band: All
  • NTP Server: 10.2.120.99, 10.2.120.98

CAUTION:
Incorrect time synchronization within the network can lead to authentication errors.
NOTES:
All APs in the group must have the same country code, so you must create a group for each country code in the network. The country code must be set before a configuration is pushed to an AP.
An NTP server defined in the Group configuration takes precedence over NTP configured with DHCP.

Step 8 On the Access Points page, select the Services tab, expand the AppRF section, implement the following settings, and then select Save Settings.

  • Deep Packet Inspection: All
  • Application Monitoring: Slide to the right
  • AirSlice Policy: Slide to the right

NOTES:
Aruba AppRF is an application aware firewall running within the APs providing application visibility and control capabilities. APs with Deep Packet Inspection (DPI) enabled can inspect the data payload within packets to identify applications in use. DPI also allows the creation of rules to determine client access to applications and websites, as well as traffic shaping policies. For a complete overview of Aruba AppRF, refer to the appropriate version ArubaOS User Guide.
Occasionally Central features are released under Select Availability. If a documented feature does not appear in the Central application, contact an Aruba SE or Aruba TAC to request feature access.

Configure Gateway Group Settings

Use this procedure to configure group settings for Gateways. The best practice is to put APs and Gateways in the same group in order to simplify navigation between the two settings tabs when deploying the network.

Step 1 Navigate to Central and login using administrator credentials.

Step 2 On the Aruba Central Account Home page, launch the Network Operations app.

Step 3 In the filter drop-down list, select an AOS10 Group name.

Step 4 From the left menu, select Devices, and then at the top, select Gateways.

Step 5 In the upper right of the Gateways page, select Config.

Step 6 If this is the first time using the AOS10 group to configure a Gateway, the Set Group Type popup will appear. Select Gateway and click Save Settings.

CAUTION:
If Branch Gateway is the only “Gateway” option, go back to the Global > Organization > Groups configuration page and convert the group to AOS10 before returning here to set the group type to Gateway. Do not select Branch Gateway or VPNC as they are only used for SD-Branch deployments and once the group type is set, it cannot be changed.

Step 7 Select the System tab and then the General tab.

Step 8 In the Basic Info section, implement the following settings, and the click Save Settings.

  • Password for user admin: password
  • Retype password: password

NOTE:
Configuration changes are not applied to a device until it has a System IP Address. This will be added later at the device level.

Step 9 Expand the Clock section and in the lower left corner of the NTP servers table, select the + sign.

Step 10 On the Add NTP Server page, implement the following settings, and then click Save Settings.

  • IPv4/IPv6/FQDN: IPv4
  • IPv4 address: 10.2.120.98
  • Burst mode: checkmark

Step 11 Repeat the two previous steps to enter additional NTP servers.

Step 12 In the Clock section at the bottom, click Choose a timezone, select the timezone from the drop-down list, and then click Save Settings.

Step 13 Expand the Domain Name System section, implement the following settings, and then click Save Settings

  • Domain name: Example.Local
  • Enable DNS name resolution: checkmark IPv4

Step 14 In the lower left corner of the DNS servers table, select the + sign.

Step 15 On the Add DNS server page, implement the following setting, and then click Save Settings.

  • IPv4 address: 10.2.120.98

Step 16 Repeat the two previous steps to enter additional DNS servers.

Step 17 In the upper right of the Gateways page, select Show Advanced.

Step 18 On the Gateways page, select the High Availability tab.

Step 19 In the Cluster mode section, disable Automatic clustering by moving the slider to the left.

Step 20 On the Cluster group mode popup, select Continue.
