d If you specified

KBytes/sec

for the rate limit, enter the value for the

rate limit in KBytes/sec (

0

through

65434

).

If you specify that you want a

percentage

for the rate limit, specify

the percentage in the range of from

0

through

100

percent. These

numbers are rounded to the nearest 16 KBytes/sec. A value of

0

makes all packets excess packets.

e Enter the burst size in KBytes (

16

through

8192

, with the default

value depending on your specified rate limit). The burst size is the
maximum amount of data that you can transmit at the line rate before
the transmission is policed.

f

Specify the receive ports for which you want to enable the rate limit
(specific bridge ports or all bridge ports).

If you apply the rate to only one or a subset of the bridge ports, you
are prompted to specify whether you want to define another rate limit
for another set of bridge ports. If you specify

yes

, you are prompted

to enter another rate limit and burst size for another set of ports. This
sequence of prompting continues until you specify

n

, meaning that

you do not want to define another rate limit for another set of ports.

If the receive port is the anchor port for a trunk, the rate limit applies to
each port that is associated with the trunk. For example, a rate limit of
1000 KBytes on a three-port trunk means that each port in the trunk has
the 1000-KByte limit.

7 Enter an IEEE 802.1p tag value in the range of from

0

through

7

or

none

(the default) to apply to forwarded frames.

8 Specify whether drop packets used to establish a TCP connection

(

yes,

no

). The default is

no

.

9 Set the start and end time for the control (

yes, no

). The default is

no

.

a If you specified a start and end time, enter the time type.

Time type selections are variations on days of the week and weekends
or it can be specific day (or range of days) and time. See Table 7 for a
complete listing of input time type options.

b Enter the starting day and/or time.

c Enter the ending day and/or time.
