The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Virtual Carrier Group (VCG) is bound to a Service Distribution Group (SDG) using a bind command (bind-vcg). This connects the virtual carriers to the physical ports listed in the SDG. After binding, a path from the Virtual Edge Input (VEI) is mapped to the RF ports.
In general, more than one VCG can be bound to the same SDG, only if the RF-channels in the VCG are not overlapping each other. However, one VCG cannot be bound to multiple SDGs.
If you want to configure one VCG to multiple SDGs, you should configure QAM replication instead. For more information, see Configuring QAM Replication section.
This section describes how to configure physical to virtual binding and QAM replication on Cisco cBR-8.
To bind a set of virtual RF-channels defined in the VCG to the physical port in the SDG, perform the following:
enable
configure terminal
cable video
bind-vcg
vcg vcg-name sdg sdg-name
exit
To configure QAM replication to one or more ports, add the ports to an SDG configuration as following:
enable
configure terminal
cable video
service-distribution-group name
rf-port integrated-cable slot/bay/port
rf-port integrated-cable slot/bay/port
exit
This section provides configuration examples for the physical to virtual binding configuration.
The following is a sample in which the port 7/0/2 of SDG west-region binds with 0 to 10 RF-channels of VCG movie-channels to physically identify the 7/0/2:0 to 7/0/2:10 QAM carriers.
Example 1 :
Router#config t
Router(config)#cable video
Router(config-video)#service-distribution-group west-region
Router(config-video-sdg)#rf-port integrated-cable 7/0/2
Router(config-video-sdg)#exit
Router(config-video)#virtual-carrier-group movie-channels
Router(config-video-vcg)#rf-channel 0-10 tsid 1-11 output-port-num 1-11
Router(config-video-vcg)#exit
Router(config-video)#bind-vcg
Router(config-video-bd)# vcg movie-channels sdg west-regions
The following is a sample in which the movie-channels VCG and news-channels VCG bind with west-regions SDG.
Example 2 :
Router#config t
Router(config)#cable video
Router(config-video)#service-distribution-group west-region
Router(config-video-sdg)#rf-port integrated-cable 7/0/2
Router(config-video-sdg)#exit
Router(config-video)#virtual-carrier-group movie-channels
Router(config-video-vcg)#rf-channel 0-10 tsid 1-11 output-port-num 1-11
Router(config-video-vcg)#exit
Router(config-video)#virtual-carrier-group news-channels
Router(config-video-vcg)#rf-channel 11-15 tsid 12-16 output-port-num 12-16
Router(config-video-vcg)#exit
Router(config-video)#bind-vcg
Router(config-video-bd)# vcg movie-channels sdg west-regions
Router(config-video-bd)# vcg news-channels sdg west-regions
The following is a sample in which video replication is set across 7/0/0 and 7/0/1 ports:
Example 3 :
Router#config t
Router(config)#cable video
Router(config-video)# service-distribution-group qrg-example
Router(config-video-sdg)# rf-port integrated-cable 7/0/0
Router(config-video-sdg)# rf-port integrated-cable 7/0/1
