Introduction

This document describes the most common wireless client connectivity issues scenarios and how to resolve them on Catalyst 9800 Wireless Controllers.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Cisco Catalyst 9800 Series Wireless Controllers

- Command Line Interface (CLI) access to the wireless controllers

Components Used

The information in this document is based on the Cisco IOS® XE Gibraltar 16.10 or later software and hardware versions.

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, ensure that you understand the potential impact of any command.

Collect Logs

WLC 9800 provides ALWAYS-ON tracing capabilities. This ensures all client connectivity-related errors, warnings, and notice-level messages are constantly logged and you can view logs for an incident or failure condition after it has occurred.

Note: Depending on the volume of logs generated, you can go back a few hours to several days.

In order to view the traces that 9800 WLC collected by default, you can connect via SSH/Telnet to the 9800 WLC and follow these steps (ensure your session is logged to a text file).

Step 1. Check the controller current time so you can track the logs in the time back to when the issue happened.

# show clock

Step 2. Collect syslogs from the controller buffer or the external syslog as dictated by the system configuration. This provides a quick view into the health and errors of the system if any.

# show logging

Step 3. Verify if any debug conditions are enabled.

# show debugging

IOSXE Conditional Debug Configs:

Conditional Debug Global State: Stop

IOSXE Packet Tracing Configs:

Packet Infra debugs:

Ip Address                                               Port

------------------------------------------------------|----------

Note: If you see any condition listed, it means the traces are logged up to debug level for all the processes that encounter the enabled conditions (mac address, ip address, and so on). This increases the volume of logs. Therefore, it is recommended to clear all conditions when not actively debugging.

Step 4. Assuming the mac address under test was not listed as a condition in Step 3., collect the always-on notice level traces for the specific mac address.

# show logging profile wireless filter { mac | ip } { <aaaa.bbbb.cccc> | <a.b.c.d> } to-file always-on-<FILENAME.txt>

You can either display the content on the session or you can copy the file to an external TFTP server.

# more bootflash:always-on-<FILENAME.txt>

or

# copy bootflash:always-on-<FILENAME.txt> tftp://a.b.c.d/path/always-on-<FILENAME.txt>

Conditional Debugging and Radio Active Tracing:

If the always-on traces do not give you enough information to determine the trigger for the problem under investigation, you can enable conditional debugging and capture Radio Active (RA) trace, which provides debug-level traces for all processes that interact with the specified condition (client mac address in this case). In order to enable conditional debugging, check these steps.

Step 5. Ensure there are no debug conditions enabled.

# clear platform condition all

Step 6. Enable the debug condition for the wireless client mac address that you want to monitor.

This command starts to monitor the provided mac address for 30 minutes (1800 seconds). You can optionally increase this time to up to 2085978494 seconds.

# debug wireless mac <aaaa.bbbb.cccc> {monitor-time <seconds>}

Note: In order to monitor more than one client at a time, run debug wireless mac  <aaaa.bbbb.cccc> command per mac address.

Note: You do not see the output of the client activity on the terminal session, as everything is buffered internally to be viewed later.

Step 7. Reproduce the issue or behavior that you want to monitor.

Step 8. Stop the debugs if the issue is reproduced before the default or configured monitor time is up.

# no debug wireless mac <aaaa.bbbb.cccc>

Once the monitor time has elapsed or the debug wireless has been stopped, the 9800 WLC generates a local file with the name:

ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

Step 9. Collect the file of the mac address activity. You can either copy the  ra trace  .log to an external server or display the output directly on the screen.

Check the name of the RA traces file.

# dir bootflash: | inc ra_trace

Copy the file to an external server:

# copy bootflash:ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log tftp://a.b.c.d/ra-FILENAME.txt

Display the content:

# more bootflash:ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

Step 10. If the root cause is still not obvious, collect the internal logs which are a more verbose view of debug-level logs. You do not need to debug the client again as this is only to take a further detailed look at debug logs that have been already collected and internally stored.

# show logging profile wireless internal filter { mac | ip } { <aaaa.bbbb.cccc> | <a.b.c.d> } to-file ra-internal-<FILENAME>.txt

Note: This command output returns traces for all logging levels for all processes and is quite voluminous. Engage Cisco TAC to help parse through these traces.

You can either copy the  ra-internal-FILENAME.txt to an external server or display the output directly on the screen.

Copy the file to an external server:

# copy bootflash:ra-internal-<FILENAME>.txt tftp://a.b.c.d/ra-internal-<FILENAME>.txt

Display the content:

# more bootflash:ra-internal-<FILENAME>.txt

Step 11. Remove the debug conditions.

# clear platform condition all

Note: Ensure that you always remove the debug conditions after a troubleshoot session.

Scenarios When the Client Cannot Connect

Web Authentication Credentials Do Not Work

Log example:

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-2}{1}: [auth-mgr] [27915]: UUID: 100000000015b, ra: 15, (info): [e4b3.1851.90ff:capwap_90800003] Authc failure from WebAuth, Auth event fail

Reason:

- The client is not using valid credentials

- There is no default authorization network defined on the 9800 WLC

Possible solutions:

- Ensure the client is using valid credentials

- Add a default authorization network method

GUI:

Navigate to  Configuration > Security > AAA > AAA Method List > Authorization > + Add  and create a new authorization method with these parameters.

CLI:

# config t

# aaa authorization network default local

No Valid VLAN Defined on Policy Profile

Log example:

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [epm] [25054]: UUID: 1000000000019, ra: 15, (ERR): EPM_PLUGIN_VLAN_ERR: [HDL = 0x0] Unable to get active_feature_ctx for vlan group name

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [sanet-shim-miscellaneous] [25054]: UUID: 1000000000019, ra: 15, (ERR): MAC: 0874.0277.1345  Error in fetching vlans

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [sanet-shim-miscellaneous] [25054]: UUID: 1000000000019, ra: 15, (ERR): MAC: 0874.0277.1345  building Mobile Announce Vlanid payload failed

Reason:

There is no valid VLAN defined on the policy profile assigned to the WLAN.

Solution:

1. Verify which Policy profile is used by the client.

GUI:

Navigate to  Monitoring > Wireless > Clients > Client row > Client Properties  (optional search for a specific client using its mac address).

CLI:

# show wireless client mac-address <aaaa.bbbb.cccc> detail | inc Policy Profile

Policy Profile : default-policy-profile

2. Verify which VLAN is assigned to that Policy Profile.

GUI:

Navigate to  Configuration > Tags & Profiles > Policy > Policy Profile row > Access Policies .

CLI:

# show wireless profile policy detailed default-policy-profile | inc VLAN

VLAN                          : VLAN2686

3. Ensure that the VLAN parameter has a VLAN name or VLAN ID valid and active.

GUI:

Navigate to  Configuration > Layer2 > VLAN > VLAN .

CLI:

# show vlan brief

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

1    default                          active    Te0/0/2, Te0/0/3

210  VLAN0210                         active

1002 fddi-default                     act/unsup

1003 token-ring-default               act/unsup

1004 fddinet-default                  act/unsup

1005 trnet-default                    act/unsup

VLAN Name                             Status    Ports

---- -------------------------------- --------- -------------------------------

2600 VLAN2600                         active

2601 VLAN2601                         active

2602 VLAN2602                         active

2686 VLAN2686                         active

Note: If a VLAN name is used, it is case sensitive so ensure it is exactly the same one seen on the  show vlan brief  command.

4. Fix the VLAN as needed.

GUI:

Navigate back to  Configuration > Tags & Profiles > Policy > Policy Profile row > Access Policies  and fix the VLAN.

CLI:

# config t

# wireless profile policy default-policy-profile

# shutdown

# vlan <vlan-# or vlan-name>

# no shutdown

Wrong Password

Log example:

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-1}{1}: [client-keymgmt] [27782]: UUID: 1000000000088, ra: 15, (ERR): MAC: e4b3.187c.3058  Keymgmt: Failed to validate eapol mic. MIC mismatch.

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-1}{1}: [client-keymgmt] [27782]: UUID: 1000000000088, ra: 15, (ERR): MAC: e4b3.187c.3058  Keymgmt: Failed to validate eapol key m2. MIC validation failed

Reason:

The client is entering a wrong password.

Possible solutions:

- Fix the password in the endpoint device

- Fix the password on the SSID

GUI:

Navigate to  Configuration > Wireless > WLANs > WLAN name > Security > Layer2 , and fix the password.

CLI:

# config t

# wlan <wlan-name>

# shut

# security wpa psk set-key ascii 0 <clear-text-password>

# no shut

Reason:

The client is not responding to the Extensible Authentication Protocol (EAP) packet sent by the 9800 WLC within the EAP-Request Timeout interval nor the EAP-Request Max Retries times.

Possible solutions:

- Update wireless client drivers to the latest one

- Ensure wireless client trust RADIUS' certificate

- Increase the EAP-Request Timeout and/or the EAP-Request Max Retries

CLI:

# config t

# wireless security dot1x request retries <0-20>

# wireless security dot1x timeout <1-120 seconds>

GUI:

Navigate to  Configuration > Security > Advanced EAP  and customize the needed settings.

Reason:

The AP with which the client was associated changed the channel or power, causing a radio reset.

Possible solutions:

- This is a normal behavior

- You could configure how often the 9800 WLC is allowed to make channel changes

CLI:

# config t

# ap dot11 { 5ghz | 24ghz } rrm channel dca interval <0-24>

Valid values 1,2,3,4,6,8,12 and 24 hours, 0 = 10 minutes (default)

GUI:

Navigate to  Configuration > Radio Configurations > RRM > 5 GHz Band/2.4 GHz Band > DCA > Increase Interval Setting.

Reason:

The client reached its session timeout.

Possible solutions:

- This is a normal behavior

- Increase the policy profile session timeout associated with the SSID

CLI:

# config t

# wireless profile policy <policy-profile-name>

# shutdow

# session-timeout <20-86400 seconds>

# no shutdown

GUI:

Navigate to  Configuration > Tags & Profiles > Policy > Policy Profile Name > Advanced > WLAN Timeout  and customize timers as needed.

Disconnected due to Idle Timeout

Reason:

The client did not send traffic (or enough traffic) within the idle timeout configured interval.

Possible solutions:

- This is a normal behavior

- Customize the policy profile idle settings associated with the SSID

CLI:

# config t

# wireless profile policy <policy-profile-name>

# shutdow

# idle-timeout <15-100000 seconds>

# idle-threshold  <0-4294967295 bytes>

# no shutdown

GUI:

Navigate to  Configuration > Tags & Profiles > Policy > Policy Profile Name > Advanced > WLAN Timeout  and customize the idle settings as needed.

Note: If you do not configure the idle-threshold, the client needs to send any amount of traffic within the idle-timeout period to not get disconnected. If you configure the idle-threshold, the client must send that amount of bytes within the idle-timeout to not get disconnected (that is, you configure an idle-threshold of 10 bytes and an idle-timeout of 30 seconds, the wireless clients need to send at least 10 bytes of traffic every 30 seconds to not be disconnected from the network).

The Client Moved Between SSIDs

Reason:

The client was connected to an SSID and moved to a different one.

Possible solutions:

- Normal behavior

- Remove the 2nd SSID from the client
