Configuring Radio Channel Settings Chapter 6 Configuring Radio Settings Note Cisco recommends that you use the world-mode dot11d country-code configuration interface command to configure a country code on DFS-enabled radios. The IEEE 802.11h protocol requires access points to include the country information element (IE) in beacons and probe responses. By default, however, the country code in the IE is blank. You use the world-mode command to populate the country code IE. Confirming that DFS is Enabled Use the show controller dot11radio1 command to confirm that DFS is enabled. This example shows a line from the output for the show controller command for a channel on which DFS is enabled: Current Frequency: 5300 MHz Channel 60 (DFS enabled) Blocking Channels from DFS Selection If your regulatory domain limits the channels that you can use in specific locations--for example, indoors or outdoors--you can block groups of channels to prevent the access point from selecting them when DFS is enabled. Use this configuration interface command to block groups of channels from DFS selection: [no] dfs band [1] [2] [3] [4] block The 1, 2, 3, and 4 options designate blocks of channels: • 1—Specifies frequencies 5.150 to 5.250 GHz. This group of frequencies is also known as the UNII-1 band. • 2—Specifies frequencies 5.250 to 5.350 GHz. This group of frequencies is also known as the UNII-2 band. • 3—Specifies frequencies 5.470 to 5.725 GHz. • 4—Specifies frequencies 5.725 to 5.825 GHz. This group of frequencies is also known as the UNII-3 band. This example shows how to prevent the access point from selecting frequencies 5.150 to 5.350 GHz during DFS: ap(config-if)# dfs band 1 2 block This example shows how to unblock frequencies 5.150 to 5.350 for DFS: ap(config-if)# no dfs band 1 2 block This example shows how to unblock all frequencies for DFS: ap(config-if)# no dfs band block 6-16 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points OL-8191-01
Chapter 6 Configuring Radio Settings Configuring Location-Based Services Configuring Location-Based Services This section describes how to configure location-based services using the access point CLI. As with other access point features, you can use a WLSE on your network to configure LBS on multiple access points. LBS settings do not appear on the access point GUI in this release. Understanding Location-Based Services Cisco recommends that you configure a minimum of three access points for LBS. When you configure location-based services (LBS) on your access points, the access points monitor location packets sent by LBS positioning tags attached to assets that you want to track. When an access point receives a positioning packet, it measures the received signal strength indication (RSSI) and creates a UDP packet that contains the RSSI value and the time that the location packet was received. The access point forwards the UDP packets to a location server. The location server calculates the LBS tag’s position based on the location information that it receives from the LBS-enabled access points. If your network has a WLSE, the location server can query the WLSE for the status of LBS-enabled access points. Figure 6-2 shows the basic parts of an LBS-enabled network. Figure 6-2 Basic LBS Network Configuration LBS access point WLSE LBS access point LBS access point LBS location server 127867 The access points that you configure for LBS should be in the same vicinity. If only one or two access points report messages from a tag, the location server can report that the location of the tag is somewhere in the coverage area of the two reporting access points. Consult the documentation for your LBS tags and location server for additional configuration details. Configuring LBS on Access Points Use the CLI to configure LBS on your access point. Beginning in privileged EXEC mode, follow these steps to configure LBS: Command Purpose Step 1 configure terminal Enter global configuration mode. Step 2 dot11 lbs profile-name Create an LBS profile for the access point and enter LBS configuration mode. OL-8191-01 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points 6-17
