Rate Limiting

The Inbound and Outbound Rate Limit is enforced on a per-station basis whether the rate limit is assigned to a rule, role or WLAN (Wireless Local Area Network). Each station has its own set of counters that are used to monitor its wireless network utilization. Traffic from other stations never count against a station's rate limits.

• Controllers support up to 128 system wide rate profiles when managed from the controller.
• Each role can use a maximum of 9 inbound rate profiles and 9 outbound rate profiles. For each direction there can be one rate profile assigned by the role's default CoS (Class of Service) and 8 other rate profiles assigned by the role's rules.
• There is no limit to how many rules allow CoS assignments as long as there are never more than 8 + 8 rate profiles assigned by Classes of Service.

If two or more rules in the same role assign the same named rate profile to a station's packets, then those rules "share" the rate profile. In Rate Limiter Example, a role's rules assign both HTTP and FTP traffic to the same rate limiter. The sum of the amounts of HTTP and FTP traffic determine whether the rate limit is being exceeded. Each station gets its own set of rate limiters. So the HTTP and FTP traffic of other stations never gets counted against a station's own rate profile limits.
