Introduction
Components used
Brief PEM State on show client output
Scenario 1: Mis-configured passphrase for WPA/WPA2 PSK authentication on client
Scenario 2: Wireless Phone Handsets(792x/9971) Failing to associate with wireless “leavingservice area”
Scenario 3: Client configured for WPA but AP configured only for WPA2
Scenario 4: Parsing AAA Return or Response codes.
Scenario 5: Client failing to associate to AP
Scenario 6: Client disassociation due to Idle Timeout
Scenario 7: Client disassociation due to Session Timeout
Scenario 8: Client disassociation due to WLAN changes
Scenario 9: Client disassociation due to manual deletion from WLC
Scenario 10: Client disassociation due to Authentication timeout
Scenario 11: Client disassociation due to AP Radio Reset (Power/Channel)
Scenario 12: Symantec Client issues with 802.1X 'timeoutEvt'
Scenario 13: Air Print service not showing up for clients with mDNS snooping turned on
Scenario 14: Apple IOS client 'Unable to join the network' due to disabled Fast SSID change
Scenario 15: Successful client LDAP association
Scenario 16: Client authentication failed on LDAP
Scenario 17: Client association issues due to LDAP is mis-configured on WLC
Scenario 18: Client association issues when LDAP server is unreachable
Scenario 19: Apple client roaming issues due to missing Sticky Roaming configuration
Scenario 20: Verifying Fast-Secure-Roaming (FSR) with CCKM
Scenario 21: Verifying Fast-Secure-Roaming (FSR) with WPA2 PMKID Caching
Scenario 22: Verifying Fast-Secure Roaming with Proactive Key Caching
Scenario 23: Verifying Fast-Secure-Roaming (FSR) with 802.11r

Introduction
This is a cheat sheet for parsing through debugs (usually "debug client <mac address>") for
common wireless issues. Parsing through “show client” and debugs will require us to first
understand some PEM states and APF states.

This document applies equally to all "AireOS" controllers. Those are, at time of writing this
document, the 440x, the 5508, 5520, 75xx,85xx, 2504 and vWLC as well as Wisms. Although
many concepts are identical in Converged Access IOS-XE controllers and switches, this document
does not apply to them as outputs and debugs are radically different.
