Cisco Wireless LAN Controller Configuration Guide

OL-17037-01

Chapter 7      Controlling Lightweight Access Points

Configuring Link Latency

Note

Link latency calculates the CAPWAP response time between the access point and the controller. It does 
not measure network latency or ping responses.

The controller displays the current round-trip time as well as a running minimum and maximum 
round-trip time. The minimum and maximum times continue to run as long as the controller is up or can 
be cleared and allowed to restart.

You can configure link latency for a specific access point using the controller GUI or CLI or for all 
access points joined to the controller using the CLI.

Using the GUI to Configure Link Latency

Using the controller GUI, follow these steps to configure link latency.

Step 1

Click 

Wireless

 > 

Access Points

 > 

All APs

 to open the All APs page.

Step 2

Click the name of the access point for which you want to configure link latency.

Step 3

Click the 

Advanced

 tab to open the All APs > Details for (Advanced) page (see 

Figure 7-25

).

Figure 7-25

All APs > Details for (Advanced) Page

Step 4

Check the 

Enable Link Latency

 check box to enable link latency for this access point or uncheck it to 

prevent the access point from sending the round-trip time to the controller after every echo response is 
received. The default value is unchecked.

Step 5

Click 

Apply

 to commit your changes.

Step 6

Click 

Save Configuration 

to save your changes.

Step 7

When the All APs page reappears, click the name of the access point again.
