Air Slice

Aruba's key RF Radio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. differentiation, Air Slice, designed for 11ax APs optimizes user experience and assures QoA to enterprise applications. Air Slice combines AppRF and UCC Unified Communications and Collaboration. UCC is a term used to describe the integration of various communications methods with collaboration tools such as virtual whiteboards, real-time audio and video conferencing, and enhanced call control capabilities. for classifying applications and it also supports custom flow definitions. Air Slice uses a combination of priority queuing, dynamic WMM Wi-Fi Multimedia. WMM is also known as WME. It refers to a Wi-Fi Alliance interoperability certification, based on the IEEE 802.11e standard. It provides basic QoS features to IEEE 802.11 networks. WMM prioritizes traffic according to four ACs: voice (AC_VO), video (AC_VI), best effort (AC_BE), and background (AC_BK). boosting, and 11ax based radio resource scheduling to prioritize enterprise applications in the presence of competing background traffic flows to meet latency and bandwidth requirements. Air Slice solution built on OFDMA, MU-MIMO Multi-User Multiple-Input Multiple-Output. MU-MIMO is a set of multiple-input and multiple-output technologies for wireless communication, in which users or wireless terminals with one or more antennas communicate with each other. , and TWT constructs offer the following services:

  • Guaranteed bit rate
  • Battery life extension
  • Bounded latency and jitter

Air Slice supports multiple services like gaming, IoT Internet of Things. IoT refers to the internetworking of devices that are embedded with electronics, software, sensors, and network connectivity features allowing data exchange over the Internet., voice and video, and so on. Air Slice support is available for all AP clients. However, 802.11ax clients have enhanced benefits due to efficient uplink and downlink traffic scheduling of 802.11ax standard. Air Slice also allows network administrators to select a list of applications to be prioritized.

Air Slice is supported only on 530 Series and AP-555 access points. It is mandatory to enable DPI Deep Packet Inspection. DPI is an advanced method of network packet filtering that is used for inspecting data packets exchanged between the devices and systems over a network. DPI functions at the Application layer of the Open Systems Interconnection (OSI) reference model and enables users to identify, categorize, track, reroute, or stop packets passing through a network. on the AP before configuring Air Slice, else an error will be reported.

The following procedure configures Air Slice Policy and Application Monitoring on an Instant AP:

  1. Navigate to Configuration > System > General.
  2. Click the Show advanced options tab.
  3. Slide the toggle switch next to AirSlice policy, to the right, to enable the feature.
  4. Slide the toggle switch next to Application monitoring, to the right, to enable the feature.
  5. Click Save.

ACL Rule Modifications

The session acl list and acl rule list are modified based on the network configuration. When rule action is permitted, the rule can configure the new option markapp with custom appid. Instant allows multiple rules to configure the same custom name, and once the ACL Access Control List. ACL is a common way of restricting certain types of traffic on a physical port. is active, the action takes effect with the custom application ID on the session.

The following procedure configures a custom application ID in the access rule:

  1. Navigate to Configuration > Security > Roles. The settings in the Roles tab are displayed.

  2. Select the role for which you want to configure access rules.

  3. In the Access rules section, click + to add a new rule. The New rule window is displayed.

  4. Ensure that the rule type is set to Access Control.

  5. Select Network under the Service category.
  6. Under Options, select the Mark Application checkbox.
  7. Select one of the custom values from the drop-down list.
  8. Click OK.

Alternatively, you can configure access rules for a wired or wireless client through the WLAN Wireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. wizard or the Wired Profile window.
