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 Cisco® cBR-8 Converged Cable Access Router Supervisor 250G performs the data forwarding and routing processing functions of the carrier-class cBR-8 Converged Cable Access Router.
The complete supervisor consists of two Field-Replaceable Units (FRUs): supervisor and supervisor Physical Interface Card (PIC). The supervisor PIC has all the physical interface ports and related PHY components onboard.
The Supervisor 250G offers:
● Flexible data path interconnection between active and standby supervisors to support active-active backhaul connectivity across all 4x100G ports from two supervisors in a cBR-8 system
● 1+1 redundant supervisor support
● Two integrated 100G Network-Side Interface (NSI) backhaul interfaces and one RJ45 GE management port support for IEEE-1588 PTP
● Field-replaceable and hot-swappable capabilities for minimal service disruption
● Industry-leading Cisco IOS® Software features and services
