**Table 2** Possible reasons and suggestions for STAs to go offline
Reason Why a STA Goes Offline	Suggestion
A STA goes offline properly.	No action is required.
STA entry addition times out or fails.	Check the intermediate network between the AP and AC or reassociate the STA with the network. If this fault persists, contact technical support personnel.
Authentication fails in the association stage.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The configuration is modified.	Check whether configuration change records exist.
Roaming check failed (on the eSAP).	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
Roaming failed (because of a roaming entry failure on the forwarding side or a failure to obtain the configuration).	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The AP is faulty.	Check the reason why the AP goes offline, and rectify the fault accordingly. For reasons why an AP goes offline, see display ap offline-record.
The AP is deleted.	No action is required.
Failed to synchronize user entries between the AP and AC.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
Failed to synchronize user entries in a mobility group.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
Failed to synchronize user entries between WMP and eSAP.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
A tunnel between ACs goes Down.	Check the network between the ACs.
The home AP goes offline or a network fault occurs.	Reassociate the STA with another AP. If this fault persists, contact technical support personnel.
The home AP is deleted.	Reassociate the STA with another AP. If this fault persists, contact technical support personnel.
The home VAP is deleted.	Reassociate the STA with another VAP. If this fault persists, contact technical support personnel.
The AC forcibly disconnects idle STAs.	Check whether this function is required. If so, no action is required. If not, run the undo idle-cut (service scheme view) command to modify the configuration as required.
The STA roams out of the device. The STA roamed.	No action is required.
The keepalive packet on the home AP times out.	Check the intermediate network between the AP and AC or reassociate the STA with the network. If this fault persists, contact technical support personnel.
The keepalive packet between ACs times out.	Check the intermediate network between the ACs or reassociate the STA with the network. If this fault persists, contact technical support personnel.
Layer 3 roaming is disabled.	Reassociate the STA with the network or enable Layer 3 roaming.
The STA fails the roaming security check: APs before and after roaming use different security policies.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The STA fails the roaming status check.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The STA fails the roaming check due to other reasons.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
Failed to add FPI item: Authorization information fails to be delivered.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The STA MAC is added to the STA blacklist.	Check whether the STA needs to be added to the blacklist.
Users go offline due to WDS link disconnection or other unknown reasons (reported by Wi-Fi).	Reassociate the STA with the network. If this fault persists, contact technical support personnel.
The STA disassociates with the network.	Check whether the user actively goes offline or whether the terminal is faulty.
The STA is deauthenticated.	Check whether the user actively goes offline or whether the terminal is faulty.
The STA ages out.	No action is required.
The VAP goes down because the configuration is modified.	Check whether configuration change records exist in the log.
The number of users exceeds the specifications (insufficient key slots).	Expand the AP capacity or reassociate the STA with another AP.
A user exception is detected.	Rectify the fault and reassociate the STA with the network. If this fault persists, contact technical support personnel.
The STA does not respond.	Check whether the STA works properly.
The STA is added to the dynamic blacklist.	Check whether the STA is an attacker.
The signal strength is too low.	Check whether the threshold for quickly disconnecting STAs by smart roaming is correctly configured, and check whether the WLAN coverage area is sufficient.
The STA rate is too low.	Check whether the threshold for quickly disconnecting STAs by smart roaming is correctly configured, and check whether the WLAN coverage area is sufficient.
The STA uses a bogus IP address.	Configure the STA to automatically obtain an IP address.
No control entry exists.	Reassociate the STA with the network. If this fault persists, contact technical support personnel.

Higher-priority STAs access the network.	Configure the STA as a high-priority STA, or increase the user CAC threshold or the maximum number of STAs on a VAP.
The number of STAs reached the CAC or VAP threshold.	Increase the user CAC threshold or the maximum number of STAs on a VAP.
