Radio Manager FAQs and Troubleshooting
Possible Cause This is because the very first aggregations are based on day and time that the WLSE’s
system software was installed, and the formula for computing the next aggregation is causing this
discrepancy.
Recommended Action No action is required. Subsequent aggregations will occur at the normal
intervals.
Symptom In the Group Client Association Report, the Number of Clients Associated with this Group
displays a 0 (zero).
Possible Cause The devices in the group have IOS version 12.3(2)JA or earlier, which will provide
a negative value for the number of clients associated.The WLSE ignores negative values and reports
them as 0.
Recommended Action Upgrade the devices to the latest IOS version.
