PurposeCommand or Action
Specifies the interface to be configured.interface {wideband-cable |
interface-cable }slot/subslot /port
:interface-num
Step 3
The valid values for the arguments depend
on CMTS router and cable interface line
card. See the hardware documentation for
your router chassis and cable interface line
card for supported values.
Note
Example:
Router(config)# interface
wideband-cable 1/0/0:0
Configures the maximum usable bonus bandwidth
for a BG.
cable acfe max-bonus-bandwidth
bonus-bandwidth
Example:
Router(config-if)# cable acfe
max-bonus-bandwidth 1000000
Step 4
Exits interface configuration mode and returns to
privileged EXEC mode.
end
Example:
Router(config)# end
Step 5
Verifying the Fairness Across DOCSIS Interfaces
To monitor the Fairness Across DOCSIS Interfaces feature, use the following procedures:
Verifying Reservable Bandwidth
To display the reserved and reservable bandwidth for a particular interface, use the show interface
{wideband-cable | modular-cable | integrated-cable} command as shown in the example:
Router# show interfaces wideband-cable 1/0/0:1 downstream
Total downstream bandwidth 1875 Kbps
Total downstream reserved/reservable bandwidth 20000/1500 Kbps
Total downstream guaranteed/non-guaranteed bonus bandwidth 20760/9741 Kbps
Router#
The “reservable bandwidth” is a part of the guaranteed bandwidth from the legacy configuration. When the
Fairness Across DOCSIS Interfaces feature is disabled, values of both the “guaranteed bonus bandwidth” and
“non-guaranteed bonus bandwidth” is zero. When the feature is enabled, the “reservable bandwidth” and
“guaranteed bonus bandwidth” represents the maximum CIR that can be reserved on the interface. Unicast
CIR flows exceeding this limit are rejected. The additional “non-guaranteed bonus bandwidth” allows the
multicast CIR flows to pass the AC module. However, the service flow may not be created successful because
the bandwidth comes from the shared pool.
