Parameters

Parameter

Description

Value

all

Displays going-online failure records of all STAs.

-

ap-name ap-name

Displays records of STAs' failures to go online on the AP with a specified name.

The AP name must exist.

ap-id ap-id

Displays records of STAs' failures to go online on the AP with a specified ID.

The AP ID must exist.

sta-mac sta-mac-address

Displays online failure records of the STA with the specified MAC address.

The STA's MAC address must exist.

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

If a STA fails to go online, you can run the command to check the failure reason, which helps locate the fault.

After the number of records of STAs' failures to go online reaches the maximum that can be stored, new records overwrite existing ones.

Example

# Display online failure records of all STAs.

<HUAWEI> display station online-fail-record all

Table 11-90  STAs' going-online failure reasons and handling suggestions

Reason Why a STA Fails to Go Online

Remarks

Handling Suggestion

STA authentication times out.

-

Reassociate the STA with the network. If the failure persists, contact technical support personnel.

Invalid association request packet.

-

Reassociate the STA with the network. If the failure persists, the STA may be incompatible with the AP. Contact technical support personnel.

The encryption mode is inconsistent on the STA and AP.

-

Ensure that the encryption mode is consistent on the STA and AP.

Authentication fails in the association stage.

-

Reassociate the STA with the network. If the failure persists, contact technical support personnel.

The STA is not authenticated.

-

Reassociate the STA with the network. If the failure persists, contact technical support personnel.

The AP does not support the rate set specified in the association request packet of the STA.

-

Change the basic rate set in the radio profile and reassociate the STA with the network.

The encryption algorithm is inconsistent on the STA and AP.

-

Ensure that the encryption algorithm is consistent on the STA and AP.

Failed to decrypt the challenge packet.

-

Verify that the STA works properly and reassociate the STA with the network. If the failure persists, contact technical support personnel.

Access from legacy STAs is denied.

-

Verify that access from legacy STAs is denied. To allow access from legacy STAs, run the undo legacy-station disable command.

The number of STAs exceeds the physical specifications allowed by the AP.

-

Expand the network capacity or retain the current configuration as required.

The WMM capability of the STA and VAP does not match.

-

Check whether the VMM function is enabled in the radio profile or check the WMM configuration on the STA.

STAs have a compatibility issue(Incorrect network type flag carried by STAs).

-

Verify that the STA works properly and reassociate the STA with the network. If the failure persists, contact technical support personnel.

STAs have a compatibility issue(STAs do not support short timeslots).

-

Check whether the STA supports 802.11g.

STAs have a compatibility issue(STAs do not support DFS.)

-

Check whether the STA supports 802.11h.

The number of associated STAs exceeds the maximum allowed by the AC.

The number of associated STAs on the AC exceeds the maximum.

Expand the network capacity or retain the current configuration as required.

The STA is not in the global whitelist.

-

Check whether the STA needs to be added to the global whitelist.

The STA is in the global blacklist.

-

Check whether the STA needs to be added to the global blacklist.

The STA is not in the VAP's whitelist.

-

Check whether the STA needs to be added to the VAP's whitelist.

The STA is in the VAP's blacklist.

-

Check whether the STA needs to be added to the VAP's blacklist.

The STA associates with a heavily loaded radio.

-

Check whether the threshold for load balancing is proper.

The STA is in the dynamic blacklist.

-

Check the attack records and check whether the STA has initiated attacks.

The association or reassociation packet check fails.

-

Reassociate the STA with the network. If the failure persists, contact technical support personnel.

-

Expand the network capacity or run the max-sta-number command to increase the maximum number of STAs associated with the VAP.

The STA uses a static IP address.

-

Check whether the STA uses a static IP address. If not required, configure the STA to obtain an IP address dynamically.

The STA's SNR is below the user CAC threshold.

-

Check whether the SNR-based user CAC threshold is proper. To change the threshold, run the uac client-snr threshold command. Reassociate the STA with the network. Alternatively, determine the STA location and provide coverage to the location.

The number of STAs exceeds the UAC threshold of the radio.

The number of associated STAs exceeds the user CAC threshold based on the number of users.

Check whether the user CAC threshold based on the number of users is properly set. If not, modify the threshold by running the uac client-number threshold command and reassociate the STA with the network.

-

Reassociate the STA with the network. If the failure persists, contact technical support personnel.

The number of associated STAs exceeds the maximum allowed by the central AP.

Expand the network capacity or retain the current configuration as required.

Key negotiation fails(the length of the key data(2/4) is invalid).

-

Verify that the correct password is entered on the STA. If this fault persists, contact technical support personnel.

Key negotiation fails(the length of the key data(4/4) is invalid).

-

Verify that the correct password is entered on the STA. If this fault persists, contact technical support personnel.

Key negotiation fails(fail to send the handshake packet).

-

Verify that the correct password is entered on the STA. If this fault persists, contact technical support personnel.
