Noted that there was a large unseen number of old BSS's , the premise is to purge the unseen devices from memory.
Need to create a rule to purge any BSS's not seen in 30 days
Under Configuration à
Operations Management à
Device Action Manager à
Choose to create new Rule Set
Under DEVICE LAST SEEN – Choose EDIT
For this example, we choose 30 days. This would be a good starting point
Under Device TYPE
Choose “Select All”
Remember to save your work
When Done make sure the rule is Assigned.
