Configuring Fair Bandwidth Sharing During Congestion
Step 3
Router(config-pmap-c)#
bandwidth
{
bandwidth-kbps
|
percent
percentage
|
remaining percent
percentage
}
Specifies the amount of bandwidth (in kbps or as a percentage of
available bandwidth) to be assigned to the class. The amount of
bandwidth configured should be large enough to also
accommodate Layer 2 overhead.
bandwidth-kbps
specifies or modifies the minimum bandwidth
allocated for a class belonging to a policy map. Valid values are
from 8 to 2,488,320, which represents from 1 to 99 percent of the
link bandwidth.
Note
The range of valid values for
bandwidth-kbps
might be
smaller than the values indicated above. Use the question
mark (?) in context-sensitive help to display the range of
valid values.
percent
percentage
specifies or modifies the minimum
percentage of the link bandwidth allocated for a class belonging
to a policy map. Valid values are from 1 to 99.
remaining percent
percentage
specifies or modifies the
minimum percentage of unused link bandwidth allocated for a
class belonging to a policy map. Valid values are from 1 to 99.
Step 4
Router(config-pmap-c)#
random-detect
Enables weighted random early detection (WRED).
Note
When you specify the
random-detect
command, the
policy map uses WRED to drop packets, not tail drop. If
you configure a class to use WRED, you must ensure that
WRED is not configured on the interface to which you
intend to attach the service policy.
