Probable Cause
Possible Solution

Faults > Display Faults

The Display Fault view is blank.

There are no faults to report based on the filtering criteria you entered.

Not applicable.

The Description column in the Display Faults table shows, "SNMP query received authentication error response."

The user created for community strings does not have Admin, Ident, Firmware, and SNMP privileges.

Make sure the SNMP community string set on the WLSE (Administration > Discover > Device Credentials.) is the same as the string set on the access point (Setup > Security > User Information).

The Description column in the Display Faults table shows, "Authentication failed. Please check LEAP credentials."

The server is reachable but the credentials are incorrect.

Make sure that the credentials are set correctly by selecting Administration > Discover > LEAP, RADIUS, or EAP-MD5 Server.

Faults > Notification Settings

Probable Cause
Possible Solution

Configure > Templates

The access point is inaccessible through the HTTP port set through template configuration job.

The HTTP port setting does not take effect until the access point is cold restarted.

Cold restart the access point.

Template configuration job fails every time.

The access point is not set up properly.

Make sure the WLSE is configured as a TFTP server for the access point.

For additional information, see Set Up Devices.

Configure > Jobs

The Undo function does not work.

Your job includes custom values.

None.

Your job includes routing table configurations (only for versions prior to 11.23T).

Your job for undoing a user shows as successful but the user is not removed from the access point.

The Undo function only works for new users that are added to the access point.

If a user is being added in place of an existing user on the access point, the existing user will remain after the Undo job.

   

Your job includes the following Security options, which are not supported by the Undo function:

Local Admin Authentication under the Local Admin Access

Encryption Key Values under Local AP/Client Security

Shared Secret under Server-Based Security.

Shared Secret under Accounting.

 

Your job includes the FTP username and password.

You are trying to Undo a job that has already been undone.

Your job is HTTP-based but you have not set up the HTTP credentials.

Add HTTP credentials using Administration >Discover >Device Credentials > HTTP User/Password

You are trying to Undo a job that contains Custom values, which are not supported by the Undo function.

None.

Configure > Jobs

An HTTP job does not run or fails.

The credentials are not set properly.

Make sure the credentials on the WLSE are the same as the credentials on the access point or bridge using Administration > Discover > Device Credentials.

Make sure the credentials on the access point or bridge have firmware rights.

The TFTP server is not set up correctly.

The TFTP setting on the access point should point to the WLSE as its TFTP server. This can be done by applying a template configuration, containing TFTP server settings, through an SNMP job (only 11.08T and higher)

The device is not responding to HTTP jobs.

HTTP browsing is disabled on the AP because of this job run.

At the access point console, turn on non-console browsing, or schedule an SNMP job for the device if its version is11.08T or higher.

An SNMP job does not run or fails.

The community string is not set properly.

Make sure the SNMP community string set on the WLSE is the same as the string set on the access point or bridge using Administration > Discover > Device Credentials.

Make sure the SNMP community string on the access point or bridge has firmware rights.

Configure > Jobs

The job failed.

There are multiple reasons a job may have failed.

Make sure all the bootstrapping steps have been performed correctly on the access point.

Check the jobvm.log by selecting Administration > Appliance > Status > View Log File to further identify and report the problem.

When applying a configuration template on a job with multiple devices, if the job fails on even one of the devices, the job is categorized as Failed.

Check if the Job Run Detail > Job Run Log to identify exactly which job(s) failed.

The job is unverified.

If after applying a configuration template on a device, the device reboots, the job will be categorized as Unverified.

Check the access point to verify whether the job has completed and the new template has been applied.

The job failed and the Job Run Detail > Job Run Log indicates a timeout while reaching the device.

The configuration template you applied has caused the device to either reboot or made it inaccessible.

Make sure the configuration you apply will not cause the device to become inaccessible. For example, do not set up access lists that block all traffic to the Ethernet port.

If the device is inaccessible, it might have rebooted after the configuration template was applied. Refer to the template screens to see if any variable is set with an R indicating a possible reboot if the setting is applied.

Configure > Jobs

The job is reported as failed, but the configuration was applied successfully to the devices.

The SNMP timeout to the device is too short.

Select Administration > Discover > Device Credentials > SNMP Communities and increase the SNMP timeout.

The job completed with errors.

This error can be seen in jobs where pre- or post- configuration backups before or after applying the new configuration fail, but the new configuration is applied successfully.

Check if "Completed with errors" appears in the Job Run Detail > Job Run Log to identify this problem.

There is a time discrepancy in scheduled jobs.

The time is not set correctly on the WLSE.

1. Reset the WLSE time to Universal Coordinated Time (UTC) using CLI commands as follows:

a. Enter services stop to stop services.

a. Enter the clock command to reset the time.

a. Enter services start to restart the services.

2. Set the time in local browser time, select Administration > Appliance > Time/NTP/Name.

Firmware is not updated on all the devices included the job.

There were warnings during the job but Ignore Warnings was not set. A firmware job runs even though there are warnings, but the job fails for the devices that had warnings.

Select Ignore Warnings in Firmware > Jobs > Create Job before running the job. See Finishing the Job.

Email about job completion fails to arrive at destination.

The SMTP server is not specified.

Configure the mail route by selecting Administration > Appliance > Configure Mailroute. See Specifying an SMTP Mail Server.

Firmware > Jobs (continued)

An SNMP job fails

The read community string does not have sufficient permissions.

To allow SNMP reads, the access point mut have a user with at least SNMP and FIRMWARE permissions, and the read community defined on the WLSE must be equivalent to a user on the access point with SNMP and FIRMWARE permissions. For more information, see Set Up Devices and Specify Community Strings.
