Chapter 7 Controlling Lightweight Access Points
Cisco Aironet 1510 Series Lightweight Outdoor Mesh Access Points
Using the CLI to Enable Background Scanning
Follow these steps to enable background scanning through the CLI.
Step 1 To enable or disable background scanning on the controller, enter this command:
config mesh background-scanning {enable | disable}
The default value is enabled.
Step 2 To verify that background scanning is enabled, enter this command:
show mesh background-scanning
Using the CLI to View Neighboring Access Points and Channels
Use these commands to see neighboring access points and channels.
1. To view all access points associated to the controller, enter this command:
show ap summary
2. To view neighboring access points on all channels, enter this command:
show mesh neigh {summary | detail} Cisco_AP
Routing Around Interference
You can configure a wireless secondary backhaul between two Cisco Aironet 1510 Access Points to
provide a temporary path for traffic that cannot be sent on the primary backhaul due to intermittent
interference. Traffic is automatically diverted, as necessary, on a packet-by-packet basis from the
primary backhaul to the secondary backhaul.
Note You can configure a secondary backhaul only on mesh access points that have two radios, such as the
AP1510. This feature is not available on mesh access points with only one radio, such as the AP1505.
Possible causes of interference include:
Hidden node collisions (packets from a hidden node are sent to the access point at the same time as
an expected packet transmission)
Fading (signal attenuation)
Radio interference on the channel from a non-802.11 source
Background scanning of channels by the access point
Note See the “Background Scanning in Mesh Networks” section on page 7-33 for more details on
background scanning.
