WLSE considers hardware, both client and access points, to be trusted sources, and assumes that vendors are reporting the field correctly. WLSE expects only client machines and peripherals to emit beacons with the IBSS flag set it is very unlikely that an access point would emit an IBSS beacon. In rare cases, however, a malicious station can spoof the field. If this happens, WLSE will report whatever value the field is set to 1-51–The rogue was not running 1-52APs in Scanning-OnlyMode Intrusion Detection System Troubleshooting1-53 Interference DetectionAdmin FAQs and Troubleshooting Admin FAQs1-54 Q.How can I verify the status of the database? 1-55Redundancy State 1-56Description Description Admin Troubleshooting1-57 Redundancy State–Users can log in using their local passwords 1-58Possible Cause Someone has deleted the link 1-591-60 a.Select Faults > Manage Fault Settings1-61 Troubleshooting Tools for the WLSE ApplianceGenerating Diagnostics for Technical Assistance Viewing Log FilesInternal AAA Server WLSE Express FAQs Consolidating and Saving Log Files1-62 C H A P T E R Fault DescriptionsExplanation Access Point /Bridge FaultsFault Description Related SettingRecommended Action Fault DescriptionRelated Setting ExplanationRecommended Action Fault DescriptionRelated Setting ExplanationRecommended Action Fault DescriptionRelated Setting ExplanationRecommended Action Fault DescriptionRelated Setting ExplanationExplanation Fault DescriptionRelated Setting MIC is disabled for theFault Description Radio Interface FaultsFault Description Related SettingRecommended Action Fault DescriptionRelated Setting ExplanationExplanation 2-10Fault Description Related SettingExplanation 2-11Fault Description Related SettingExplanation 2-12Fault Description Related SettingRelated Setting Verify RM Capability2-13 Fault DescriptionRelated Setting IDS Intrusion Detection System Faults2-14 Fault DescriptionExplanation 2-15Fault Description Related SettingExplanation 2-16Fault Description Related SettingExplanation 2-17Fault Description Related SettingExplanation 2-18Fault Description Related SettingExplanation 2-19Fault Description Related SettingExplanation 2-20Fault Description Related SettingExplanation 2-21Fault Description Related SettingRelated Setting cd11IfStationRole from the2-22 Fault DescriptionExplanation 2-23Fault Description Related SettingFault Settings, then Voice FaultsWLSE Faults Faults > ManageExplanation 2-25Fault Description Related SettingFault Description AAA Server FaultsServer Type 2-26Server Type 2-27Fault Description Related SettingServer Type 2-28Fault Description Related SettingServer Type 2-29Fault Description Related SettingServer Type 2-30Fault Description Related SettingRelated Setting Switch Faults2-31 Fault DescriptionExplanation 2-32Fault Description Related SettingFault Description Router FaultWLSM Faults 2-332-34 Chapter 2 Fault Descriptions WLSM FaultsOL-8376-01 I N D E IN-1IN-2 1-62IN-3 IN-4 IN-5 detection, frequency ofIN-6 IN-7 IN-8 management of multiple subnets IN-9WLSE-WDSauthentication failed WLSM discovery log errors fault descriptionsIN-10 IndexOL-8376-01
