AP Group NTP Server

From this release, the global NTP server configuration is replaced with the per-AP group NTP server configuration. Now, you cannot configure the Cisco Hyperlocation feature without the per-AP group NTP server.

Information About AP Group NTP Server

Features such as Cisco Hyperlocation, BLE Angle of Arrival (AoA), and Intelligent Capture (iCAP) require precise time across APs within an AP group to achieve location accuracy. Because the controller and controller global NTP server are configured on the WAN, they might have large synchronization delays from the APs, and this might compromise location accuracy.

If all the APs in an AP group synchronize with the same NTP server, accurate data can be obtained to calculate the location. Configuring the NTP server locally for all the APs in an AP group helps achieve better synchronization among APs.

Configuring an AP Group NTP Server

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ap profile profile-name

Example:

Device(config)# ap profile profile-name

Configures an AP profile and enters AP profile configuration mode.

Step 3

[no] ntp ip ip-address

Example:

Device(config-ap-profile)# [no] ntp ip 9.0.0.4

Sets the IP address of the NTP server. The no form of this command removes the NTP server.

Configuring AP Timezone

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

ap profile profile-name

Example:

Device(config)# ap profile test

Configures the AP profile and enters AP profile configuration mode.

Step 3

timezone {use-controller | delta hour offset-hour minute offset-minute}

Example:

Device(config-ap-profile)# timezone delta hour -12 minute 2

Configures the timezone offset for AP.

You can configure the AP timezone only for each AP profile. You cannot configure timezone for each AP.

To configure the timezone, either apply the current controller timezone or the time difference. By default, timezone is disabled.

Verifying Cisco Hyperlocation

To display the hyperlocation status values and parameters for all the AP profiles, use the following command:

Device# show ap hyperlocation summary

Profile Name: custom-profile

Hyperlocation operational status: Down
Reason: Hyperlocation is administratively disabled
Hyperlocation NTP server: 209.165.200.224
Hyperlocation admin status: Disabled
Hyperlocation detection threshold (dBm): -100
Hyperlocation trigger threshold: 10
Hyperlocation reset threshold: 8


Profile Name: default-ap-profile

Hyperlocation operational status: Up
Reason: N/A
Hyperlocation NTP server: 209.165.200.224
Hyperlocation admin status: Enabled
Hyperlocation detection threshold (dBm): -90
Hyperlocation trigger threshold: 22
Hyperlocation reset threshold: 8

To display both the overall and and the per-AP configuration values and operational status, use the following command:

Device# show ap hyperlocation detail

Profile Name: house24

Hyperlocation operational status: Up
 Reason: NTP server is not properly configured
Hyperlocation NTP server: 198.51.100.1
Hyperlocation admin status: Enabled
Hyperlocation detection threshold (dBm): -90
Hyperlocation trigger threshold: 8
Hyperlocation reset threshold: 7

To display the overall (profile specific) configuration values and operational status for a given profile, use the following command: 

Device# show ap profile profile-name hyperlocation summary

Profile Name: profile-name
Hyperlocation operational status: Up
   Reason: N/A
Hyperlocation NTP server: 209.165.200.224
Hyperlocation admin status: Enabled
Hyperlocation detection threshold (dBm): -100
Hyperlocation trigger threshold: 10
Hyperlocation reset threshold: 8

To display both the overall (profile specific) and per-AP configuration values and operational status for a given profile, use the following command. The APs listed are only those APs that belong to the specified join profile. 

Device# show ap profile profile-name hyperlocation detail

Profile Name: profile-name
Hyperlocation operational status: Up
 Reason: N/A
Hyperlocation NTP server: 209.165.200.224
