Configuring RADIUS Server Support for Switch Services
RADIUS Server Configuration for CoS (802.1p Priority) and Rate-Limiting
N o t e s
Mixing CLI-configured and RADIUS-assigned rate-limiting on the same port
can produce unexpected results. Refer to “Per-Port Bandwidth Override” on
page 7-6.
Where multiple clients are currently authenticated on a given port where
outbound (egress) rate-limiting values have been assigned by a RADIUS
server, the port operates with the outbound rate-limit assigned by RADIUS for
the most recently authenticated client. Any earlier outbound rate-limit values
assigned on the same port for other authenticated client sessions that are still
active are superseded by the most recent RADIUS-assigned value. For exam-
ple, if client “X” is authenticated with an outbound rate-limit of 750 kbps, and
client “Y” later becomes authenticated with an outbound rate-limit of 500 kbps
while the session for client “X” is still active, then the port operates with an
outbound rate-limit of 500 kbps for both clients.
