Release	Feature	Feature Information
Cisco IOS XE Bengaluru 17.5.1	OEAP Link Test	The Cisco OEAP Link Test feature allows you to determine the DTLS upload, link latency, and jitter of the link between an AP and the controller.

Information About OEAP Link Test

The Cisco OEAP Link Test feature allows you to determine the DTLS upload speed of the link between an AP and the controller. This feature helps in identifying network bottlenecks and reasons for functionality failures. You can determine the link latency by running a test on demand.

A link test is used to determine the quality of the link between the controller and an AP in OEAP mode. The AP sends synthetic packets to the controller and the controller echoes them back to the AP, which can then estimate the link quality.

Feature Scenarios

Cisco OfficeExtend Access Point (OEAP) users are complaining of poor performance when connected to a teleworker AP.

Use Cases

This feature allows OEAP network admins to troubleshoot low throughput from the Cisco Catalyst 9800 Controller GUI by running OEAP link test.

The OEAP link test provides DTLS upload speed, link latency, and link jitter, all of which help the network administrators to narrow down the problem.

Configuring OEAP Link Test (CLI)

Procedure

Command or Action Purpose

	Command or Action	Purpose
Step 1	enable Example: `Device> enable`	Enters privileged EXEC mode.
Step 2	ap name `ap-name` network-diagnostic Example: `Device# ap name ap18 network-diagnostic`	Triggers network diagnostics on an OfficeExtend AP.

Step 1

enable

Example:

Device> enable

Enters privileged EXEC mode.

Step 2

ap name ap-name network-diagnostic

Example:

Device# ap name ap18 network-diagnostic

Triggers network diagnostics on an OfficeExtend AP.

Performing OEAP Link Test (GUI)

Procedure

Step 1

Choose Monitoring > Wireless > AP Statistics.

In the list of APs, a Link Test icon is displayed in the AP Name column for OEAP-capable APs.

Note

The Link Test icon is displayed only if an AP is OEAP capable and is configured to operate as OEAP.

Step 2

Click Link Test.

A link test is run and the results are shown.

Verifying OEAP Link Test

The following example shows how to verify network diagnostics information:

Device# show FlexConnect office-extend diagnostics
