This document desribes how to resolve the IDLE client issues while using 5760/3850/3650 next
generation Wireless LAN Controllers (WLCs) in the network as when a client stucks in the IDLE
state, they are unable to reconnect back.

There are no specific requirements for this document.

The information in this document is based on these hardware versions:

Cisco Wireless LAN Controller 5760 Release 3.3.2 (Next Generation Wiring Closet [NGWC])

●

Cisco 3702 Series Lightweight Access Point

●

Cisco Catalyst 3560 Series Switch

●

The information in this document was created from the devices in a specific lab environment. All of
the devices used in this document started with a cleared (default) configuration. If your network is
live, make sure that you understand the potential impact of any command.

Clients are unable to connect through the wireless network. Over 2000 clients are stuck in the
IDLE state on show wireless client summary command. This issue occured twice within the ten
hours and the only way to restore the network is to reboot the WLC.

TAC provides the script to collect the data from all components of the product to indentify the one,
in which the client is in the IDLE state.

After the analysis of logs, it is found that this was due to the memory leak in AVC (Application
Visibility and Control) feature. This bug is filed to track the issue and is fixed on the latest release.
