Chapter 5 Distributing Bandwidth Between Queues
Distribution of Remaining Bandwidth Using Ratio
Step 4
bandwidth remaining ratio ratio
(Optional) Specifies the bandwidth-remaining ratio for the
traffic class.
ratio is the value used to determine the amount of unused
bandwidth to allocate to each queue on the subinterface
during periods of congestion. The scheduler allocates the
excess bandwidth relative to other subinterfaces. Valid
values are 1 to 1000. The default value is
platform-dependent.
The router makes no distinction between interface types at
the class level when using the default bandwidth-remaining
ratio. On the Cisco 10000 series router the default
bandwidth-remaining ratio value is 1.
Step 5
exit
Exits policy-map class configuration mode.
Step 6
exit
Exits policy-map configuration mode.
Step 7
policy-map parent-policy-name
Creates or modifies a parent policy map. Enters policy-map
configuration mode.
parent-policy-name is the name of the parent policy map.
Step 8
class class-default
Configures the class-default class. Enters policy-map class
configuration mode.
Note The router interprets any features configured under
the class-default class as aggregate features on the
subinterface.
Step 9
shape {average | peak} cir [bc] [be]
Shapes the average or peak rate to the rate you specify.
average specifies average rate shaping.
peak specifies peak rate shaping.
cir specifies the committed information rate (CIR), in bits
per second (bps).
(Optional) bc specifies the committed burst size, in bits.
(Optional) be specifies the excess burst size, in bits.
Step 10
bandwidth remaining ratio ratio
(Optional) Specifies the bandwidth-remaining ratio for the
subinterface.
ratio is the value used to determine the amount of unused
bandwidth to allocate to each queue on the subinterface
during periods of congestion. The scheduler allocates the
excess bandwidth relative to other subinterfaces. Valid
values are 1 to 1000. The default value is
platform-dependent.
The router distinguishes between interface types at the
subinterface level when using default bandwidth-remaining
ratios. On the Cisco 10000 series router the default ratio
value is 1 for VLAN subinterfaces and Frame Relay DLCIs.
For ATM subinterfaces, the router computes the default
based on the subinterface speed.
