Does the Matrix C1 support Rate Limiting?
A1 Yes it does. A few Key points: 1. Rate limiting must be globally enabled before any enabled port rate limits will function. 2. Only Outbound rate limiting is supported. 3. The rate limiters are set per port per priority, which in turn maps to a unique Transmit Queue. The mapping cannot be altered. 4. The priority refers to the 802.1D (802.1p) port priority level associated with the port-string. The valid range is 0 – 7, with 0 being both the lowest priority and the port-level default. 5. The threshold specifies a port rate limiting threshold in kilobytes per second. The valid range is 64 up to the maximum rate for a given interface. Functionally, the specified rate limit is rounded up to the nearest 81.375 kilobytes per second, for actual application. This granularity is Functions as Designed, and is a factor of hardware.
