Downloadable Regulatory Table

The downloadable regulatory table feature allows for the update of country domain options without upgrading the ArubaOS software version. A separate file, called the Regulatory-Cert, containing AP regulatory information will be released periodically on the customer support site. The Regulatory-Cert file can then be uploaded to a managed device and pushed to deployed APs.

The Regulatory-Cert includes the following information for each AP:

• All countries supported in the current release of ArubaOS (not just United States or Rest of World or any subset of countries)
• Allowed channels for each country
• Max EIRP Effective Isotropic Radiated Power or Equivalent Isotropic Radiated Power. EIRP refers to the output power generated when a signal is concentrated into a smaller area by the Antenna. for each channel and each country in the allowed list. The max values are specified for each PHY-type at which the AP is allowed to transmit on. The classified PHY-types are

  • 802.11b 802.11b is a WLAN standard often called Wi-Fi and is backward compatible with 802.11. Instead of the Phase-Shift Keying (PSK) modulation method used in 802.11 standards, 802.11b uses Complementary Code Keying (CCK) that allows higher data speeds and makes it less susceptible to multipath-propagation interference. 802.11b operates in the 2.4 GHz band and the maximum data transfer rate is 11 Mbps. rates (CCK rates)
  • 802.11n 802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz.

Important Points to Remember

When a Regulatory-Cert is activated, the new file is checked against the default file built into ArubaOS. If the file is of a newer version, the activation is allowed. If the file is of a lower version, then the activation is not completed. The CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. of the managed device displays the following message upon failure:

(host) #ap regulatory activate reg-data-1.0_00002.txt

Failed to activate regulatory file reg-data-1.0_00002.txt. File Version should be greater than 1.0_43859

• APs do not rebootstrap or reboot on activation.
• If there is change in channel list or power level, APs will change the channel or power level. Impact is same as that of ARM Adaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. channel or power change in that case.
• Clients are not disconnected upon regulatory file activation. Max latency impact during activation (with no channel changes) is less than 1s (applies to power change too).
• With channel change, the impact is similar to ARM Adaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. channel change (depends on client behavior and if CSA Channel Switch Announcement. The CSA element enables an AP to advertise that it is switching to a new channel before it begins transmitting on that channel. This allows the clients, which support CSA, to transition to the new channel with minimal downtime. is enabled or not).
• If support for the AP (Country) is added, the AP will move from AM Air Monitor. AM is a mode of operation supported on wireless APs. When an AP operates in the Air Monitor mode, it enhances the wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more. However, clients cannot connect to APs operating in the AM mode. to AP mode (if the AP is configured in AP mode of operation).

Copying the Regulatory-Cert

You can use the following protocols to copy the regulatory file to a managed device:

• FTP File Transfer Protocol. A standard network protocol used for transferring files between a client and server on a computer network.
• TFTP Trivial File Transfer Protocol. The TFTP is a software utility for transferring files from or to a remote host.
• SCP Secure Copy Protocol. SCP is a network protocol that supports file transfers between hosts on a network.

Additionally, regulatory files saved to a USB Universal Serial Bus. USB is a connection standard that offers a common interface for communication between the external devices and a computer.

Activating the Regulatory-Cert

Once the Regulatory-Cert has been added to the managed device, the new regulatory information must be activated and pushed to the APs.

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command activates a specific regulatory file loaded on the managed device.

In a Mobility Conductor-Managed Device deployment, the file syncing profile can be enabled to ensure that the regulatory-cert that is stored on the Mobility Conductor is shared with the managed devices.

File synchronization occurs when the downloadable regulatory table is activated in the Mobility Conductor and the Mobility Conductor synchronizes the downloadable regulatory table to all managed devices within the synchronization time and is automatically activated. File syncing is enabled by default, with a default sync time of 30 minutes. The sync time can be set between 30 to 180 minutes. To configure the file syncing profile, use the following commands

(host) [md] (config) #file syncing profile

(host) [md] (File syncing profile) #file-syncing-enable

(host) [md] (File syncing profile) #sync-time 30
