HP ProCurve 6120G/XG Configuration Manual page 323

Syntax: [no] int <port-list> rate-limit all in <percent <0-100> | kbps
You can configure a rate limit from either the global configuration level or
from the port context level. For example, either of the following commands
configures an inbound rate limit of 60% on ports A3 - A5:
ProCurve (config)# int a3-a5 rate-limit all in percent 60
ProCurve (eth-A3-A5)# rate-limit all in percent 60
N o t e
You must execute a write mem to save the rate-limiting configuration to the
start-up config file.
< 0-10000000>>
Configures a traffic rate limit (on non-trunked ports) on the
link. The "no" form of the command disables rate-limiting on
the specified ports.
(Default: Disabled.)
Options include:
• in — Specifies a traffic rate limit on inbound traffic passing
through that port, or on outbound traffic.
• percent or kbps — Specifies the rate limit as a percentage of
total available bandwidth, or in kilobits per second.
Notes:
• Rate-limiting does not apply to trunked ports.
• Kbps rate-limiting is done in segments of 1% of the lowest
corresponding media speed. For example, if the media
speed is 100 Kbps, the value would be 1 Mbps. A 1-100 Kbps
rate-limit is implemented as a limit of 100 Kbps; a limit of
100-199 Kbps is also implemented as a limit of 100 Kbps,
a limit of 200-299 Kbps is implemented as a limit of 200
Kbps, and so on.
• Percentage limits are based on link speed. For example, if
a 100 Mbps port negotiates a link at 100 Mbps and the
inbound rate-limit is configured at 50%, then the traffic
flow through that port is limited to no more than 50 Mbps.
Similarly, if the same port negotiates a 10 Mbps link, then
it allows no more than 5 Mbps of inbound traffic.
Configuring a rate limit of 0 (zero) on a port blocks all traffic
on that port. However, if this is the desired behavior on the
port, ProCurve recommends using the < port-list > disable
command instead of configuring a rate limit of 0.
