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.

Effective with Cisco IOS-XE Release 3.18.0SP, Capacity BW is also displayed. It is a summation of the channel capacity of the RF channels in this interface, and the capacity of OFDM channels is calculated considering the lowest profile rate.
