Restrictions for CMTS Dynamic Bandwidth Sharing

•The bandwidth sharing state of a modular, integrated, or wideband cable interface can be changed only when the interface is administratively shutdown.

Information About CMTS Dynamic Bandwidth Sharing

The following sections provide information on DBS:

•DBS for Modular, Integrated, and Wideband Cable Interfaces

•DBS Configuration

DBS for Modular, Integrated, and Wideband Cable Interfaces

Prior to DOCSIS 3.0 standards, cable service flows were associated with a single cable interface, which in turn corresponded to a physical downstream on a line card. Under DOCSIS 3.0 standards, cable service flows can be associated with more than one downstream channel.

DBS is the dynamic allocation of bandwidth for MC, IC, and WB cable interfaces sharing the same downstream channel. The bandwidth available to each MC, IC, WB cable, or narrowband channel is not a fixed value—it depends on the configuration and the traffic load on the MC, IC, or WB cable.

The available bandwidth for data traffic is calculated using the following formula: Actual Line Rate - (Bandwidth used by MAC Management Messages [MMM] + Bandwidth loss due to DOCSIS header)

The bandwidth required by MMM depends on the CMTS configuration. The maximum bandwidth reserved for MMM is 4 percent (if the MMM uses less than 4 percent of bandwidth, the remaining unused bandwidth is available for the data traffic).

DBS enables high burst rates with DOCSIS 2.0 cable modems as well as DOCSIS 3.0 cable modems. The DBS feature continues working across line card and performance routing engine (PRE) switchovers with no loss of functionality.

DBS Configuration

Dynamic bandwidth sharing and static bandwidth allocations are configured at the MC, IC, or WB cable interface level. By default, bandwidth for an MC, IC, or WB cable channel is statically allocated. When DBS is enabled on an interface, the static bandwidth percentage is converted to a committed information rate (CIR) value for the corresponding interface. The interface CIR value represents the guaranteed portion of the interface bandwidth and is used for admission control of the service flows with minimum reserved rate. When DBS is enabled, you can also specify the remaining ratio value of the excess bandwidth for the interface. If DBS is enabled and no bandwidth percentage is specified, no bandwidth is reserved for the MC, IC, or WB cable interface and the interface is effectively in protocol down state.

Dynamic bandwidth sharing does not preclude static bandwidth configuration. If a static portion of bandwidth is configured on any RF channel that one or more DBS-enabled channel utilizes, that portion is subtracted from the CIR value of the RF link. Therefore, such a portion is always reserved and is not available to dynamic MC, IC, or WB cable interfaces.

Note Starting with Cisco IOS Release 12.2(33)SCE, the DBS mode is enabled by default, on the WB/MC/IC interfaces. To disable the DBS mode, configure the no cable dynamic-bw-sharing command.

How to Configure CMTS Dynamic Bandwidth Sharing

This section contains the following procedures:

•Configuring DBS for a Modular Cable Interface

Configuring DBS for a Modular Cable Interface

To configure DBS for an MC interface on the Cisco uBR10012 router, use the cable dynamic-bw-sharing command in interface configuration mode.

Note The interface must be administratively shutdown before DBS can be configured on the MC interface.

Configuration Examples for CMTS Dynamic Bandwidth Sharing

This section provides the following configuration examples:

•Configuring DBS on a Modular Cable Interface: Example

•Configuring DBS on a Wideband Cable Interface: Example

•Configuring DBS on an Integrated Cable Interface: Example

Configuring DBS on a Modular Cable Interface: Example

In the following example, DBS is enabled on modular cable interface 1. Because DBS is enabled, the percent value is converted to a committed information rate (CIR) of 45, which means the modular cable channel is guaranteed 45 percent of the bandwidth. The ratio of excess bandwidth is assigned a value of 22, which means that if there is excess bandwidth available, a remaining ratio of 22 can be assigned to the MC channel.

Because DBS is enabled, the percent value is converted to a CIR value of 50, which means the wideband cable channel is guaranteed 50 percent of the bandwidth. The excess-value is assigned a value of 5, which means that if there is excess bandwidth available, a remaining ratio of 5 can be assigned to the wideband channel.
