Memory Utilization
The memory utilization is affected by the number of AirGroup servers and users in an AirGroup cluster. In an
AirGroup cluster, the total number of AirGroup servers and users cannot exceed the limit defined by the top-
end controller. For example, in an AirGroup cluster of one W-3200 controller and two W-6000M3 controllers,
the cluster limit is determined as per the scaling limit of the top-end controller which is the W-6000M3
controller. For the W-3200 controller in the cluster, the controller platform limit of the W-3200 controller is
applied. Based on the memory utilization, Table 228 summarizes the maximum number of AirGroup servers
and users for all supported controller platforms.
CPU Utilization
The CPU utilization is measured by the rate at which the controller receives mDNS packets. The rate of mDNS
packets in the cluster depends on the number of AirGroup servers, users, and number of applications installed
on these devices. The rate of mDNS packets handled by the supported controller platform varies. Table 229
displays the total number of mDNS packets received per second by supported the controller platforms:
Controller Model mDNS packets per second (pps)
W-7240 100
W-7220 60
W-7210 60
W-7205 40
W-7030 50
W-7024 50
W-7010 30
W-7005 30
W-6000 20
W-3600 20
W-3400 20
W-3200 20
Table 229: mDNS Packet Limits in Controller
Use the following command to determine the number of mDNS packets received per second by the controller:
show airgroup internal-state statistics
Issue this command multiple times to measure the time difference and the mDNS packet count.
