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.
