Scalability Assumptions
Scalability is continuously tested based on the following assumptions. Deviations from these assumptions can
impact overall scalability of your AWMS server.
Table 8 Wireless Scalability Test Values
Category Value
Average density of client devices per access point 5
Device configuration auditing interval Daily
Up/Down status polling period (minutes) 5
User data polling period (minutes) 10
Thin AP discovery period (minutes) 15
Device-to-device link polling period (minutes) 20
Device bandwidth polling period (minutes) 10
802.11 counters polling period (minutes) 15
Rogue AP and device location data polling period (minutes) 30
CDP neighbor data polling period (minutes) 60
NOTE: Auditing more than once a day can have a tremendous impact on scalability.
