RADIUS Server Configuration for CoS (802.1p Priority) and Rate-Limiting
Applied Rates for RADIUS-Assigned Rate Limits
On the switches covered by this guide, rate limits are applied incrementally,
as determined by the RADIUS-applied rate. For any given bandwidth assign-
ment, the switch applies the nearest rate increment that does not exceed the
assigned value. The increments are in graduated steps, as described in table
7-3.
Table 7-3. RADIUS-Assigned Rate-Limit Increments
For example, some of the following RADIUS-assigned rates fall between their
respective incremental values, resulting in applied rates lower than the
RADIUS-assigned rates. However, others match their respective incremental
values, resulting in no difference between the RADIUS-assigned rate limits
and the applied rate limits.
