The following parameters must be configured for the WLAN MDA:
country
frequency band
channel
bandwidth
administrative status
beacon interval
The country parameter is required to bring the radio up. The country must be configured before any other MDA-level configuration can proceed and before the WLAN radio can be enabled with the no shutdown command. The country parameter is configured by entering one of the following country names in the CLI: Australia, Belgium, Bolivia, Brazil, Canada, Chile, Colombia, France, Germany, India, Iran, Italy, Japan, Malaysia, Mexico, New Zealand, Peru, Russia, Singapore, South Africa, United States, or Venezuela.
The frequency-band can be configured as either 2.4 GHz or 5 GHz. The default is 2.4 GHz. If the configured country changes, the frequency band resets to the default value.
The channel can be configured either as auto or as a specific channel identifier. The channel ID supported by the node depends on the configured country. See the Appendix for channel ID and country mappings. The default channel setting is auto. If the configured country changes, the channel resets to the default value.
A network SSID can only be configured when the country parameter is configured.
The bandwidth can be configured as either 20 MHz or 40 MHz, depending on the configured country. See the Appendix for bandwidth and country mapping. The default bandwidth is 20 MHz. If the configured country or frequency band changes, the bandwidth resets to the default value.
The WLAN station port uses the configured frequency-band to scan for an SSID that it can connect to.
The WLAN AP broadcasts a beacon packet in order to synchronize the wireless network. The frequency with which the packet is sent can be configured using the beacon-interval command.
The WLAN radio can be turned off using the shutdown command in the config>card>mda>wlan-radio context. When the WLAN radio is turned off, any configured WLAN ports become operationally down if they were not already shut down. When the no shutdown command is issued in this context, the radio is turned on and configured WLAN ports can begin operating; however, the no shutdown command cannot be issued until the country parameter is configured.
The WLAN radio can be put into reset mode using the shutdown command in the config>card>mda context. Any configured WLAN ports become operationally down when the WLAN radio is in reset mode. When the no shutdown command is issued in this context, the radio comes out of reset and configured WLAN ports can begin operating.
