Viewing the Currently Active Per-Port CoS and Rate- Limiting Configuration Specified by a RADIUS Server

While a port-access authenticated client session is active, any RADIUS- imposed port settings override their counterparts in the port’s configuration. For example, if the switch configuration allows port B1 a rate-limit of 80% of the port’s available bandwidth, but the RADIUS server specifies a rate-limit of 50% for a given authenticated client, then the switch shows the RADIUS- imposed rate-limit for that port as long as the authenticated client session is active.
