Per-Port Bandwidth Override; Ingress (Inbound) Traffic; Egress (Outbound) Traffic - HP 2530 Manual Supplement

Table 5 RADIUS-assigned rate-limit increments
RADIUS-assigned bits-per-second rate limit
For example, some of the following RADIUS-assigned rates fall between their respective incremental
values, causing applied rates lower than the RADIUS-assigned rates. However, others match their
respective incremental values, so there is no difference between the RADIUS-assigned rate limits
and the applied rate limits.

Per-port bandwidth override

HP recommends that rate-limiting be configured either through RADIUS assignments or static CLI
configuration unless the override described below is specifically desired.

Ingress (inbound) traffic

RADIUS-assigned ingress rate-limits are applied to individual clients, not to the client's port. But if
you use the CLI to configure a per-port ingress rate-limit on the same port where an authenticated
client receives a RADIUS-assigned ingress rate-limit, the client's assigned ingress limit can be
reduced by the CLI-configured port ingress limit, if the port reaches its CLI-configured rate-limit
maximum before the client reaches its RADIUS-assigned rate-limit maximum, thus denying the client
its intended maximum.

Egress (outbound) traffic

The most recent RADIUS-assigned egress rate-limit specifies the maximum egress rate-limit for a
port, even if the CLI has also been used to configure an egress rate limit on the port.

Rate-limit actions and restrictions
Determines the maximum ingress bandwidth available on the port,
regardless of any RADIUS-assigned per-client rate-limits dynamically
assigned to the same port.
Each client is allowed the inbound bandwidth individually assigned to it
by the RADIUS server, up to the port's physical capacity, unless the
available bandwidth on the port has been reduced by a CLI-assigned
per-port bandwidth limit.
