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.

AP group NTP server

An AP group NTP server is a time synchronization mechanism that

  • ensures precise time alignment across all APs within an AP group to achieve location accuracy

  • reduces synchronization delays compared to using a WAN-based global NTP server, and

  • supports features that rely on accurate timing, such as Cisco Hyperlocation, BLE AoA, and Intelligent Capture.

If your controller and global NTP server are configured on the WAN, the APs may experience significant synchronization delays. These delays can reduce location accuracy.

When all APs in a group synchronize with the same NTP server, you can obtain accurate data for location calculations. Configure the NTP server locally for all APs in an AP group to improve synchronization among the APs.

Feature Description

AP group NTP server

Cisco IOS XE 17.6.1

From this release, the global NTP server configuration is replaced with per-AP-group NTP server configuration. Per-group NTP is now required for the Cisco Hyperlocation feature.

These commands are introduced:

  • ntpauth-key

  • timezonedelta

  • timezoneuse-controller

  • showap name ntp status

  • showap ntp status

  • showap timezone

Configure an AP group NTP server (CLI)

Set a Network Time Protocol (NTP) server for AP groups to ensure time synchronization.

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Configure an AP profile and enter the AP profile configuration mode.

Example:

Device(config)# ap profile profile-name

Step 3

Set the IP address of the NTP server.

Example:

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

The no form of this command removes the NTP server.

Configure AP timezone (CLI)

Set the correct timezone for APs to ensure accurate time-stamping and scheduling using commands.

Procedure

Step 1

Enter the global configuration mode.

Example:

Device# configure terminal

Step 2

Configure the AP profile and enter the AP profile configuration mode.

Example:

Device(config)# ap profile test

Step 3

Configure the timezone offset for AP.

Example:

Device(config-ap-profile)# timezone {use-controller | delta hour -12 | minute 2}

You can configure the AP timezone for each AP profile only. It is not possible to configure the timezone for individual APs.

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

Verify Cisco Hyperlocation

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

Device# show ap hyperlocation summary
                
Profile Name: custom-profile
Hyperlocation operational status: Down
Reason: Hyperlocation is administratively disabled

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

Device# show ap profile profile-name hyperlocation summary
