Table 245: AirGroup Server and User Limits in Switch
In a multi-switch deployment, there is a scaling limit of 2,000 AirGroup servers and 16,000 AirGroup users for all
switches in a cluster. If you require more servers and users than the prescribed limit, configure multiple clusters, so
that each cluster is within the prescribed limit.
The AOS-W scaling limits are based on the following metrics:
n Memory Utilization
n CPU Utilization
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 switch. Based on the memory utilization, Table 245 summarizes the maximum number of AirGroup
servers and users for all supported switch platforms.
CPU Utilization
The CPU utilization is measured by the rate at which the switch 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 switch platform varies. Table 246
displays the total number of mDNS packets received per second by supported the switch platforms:
