QoS Controls 491
■
For the rate limit type receivePort or aggregate, the following:
■
Service level for nonconforming excess (packets exceeding the rate
limit)
■
Whether nonconforming excess are loss eligible. The default is yes.
■
How the rate limit is expressed (percentage of port bandwidth or
KBytes/sec)
■
Rate-limit value (0 to 65434 Kbytes or 0 to 100 percent).
■
A burst size in KBytes ( 16 through 8192 , with the default value
dependent on your specified rate limit).
■
Bridge ports for which you want to enable the specified rate limit
value (specific bridge ports or all bridge ports). If you specify a
subset of available ports, you can enter another rate-limit value for
another set of ports.
■
For any type of rate limit (and a service level other than drop), any
combination of IEEE 802.1p priority tag values in the range
0 to 7 or
none to apply to forwarded frames. By default, no tags are applied,
unless the associated classifier defines a tag value. In that case, the tag
value from the associated classifier is used for the forwarded frames.
■
Whether to drop packets used to establish TCP connections. This is a
form of one-way filtering for flow classifiers only. The default is no.
■
Enable control start and stop times. Similar to how a VCR operates,
this timer allows you to set the desired beginning and ending period
for a control. The default is no.
If you select yes, you set the following:
■
Input time type such as daily, weekdays, or weekends. You can also
choose a “specific” type that lets you choose an exact day.
■
One or more classifiers (classifier numbers) that are subject to this
control.
