Cisco CMTS Feature Summary
Feature Category Item
Routing Protocols Border Gateway Protocol (BGP).
Intermediate System-to-Intermediate System (IS-IS).
Open Shortest Path First (OSPF).
Interior Gateway Routing Protocol (IGRP).
Enhanced Interior Gateway Routing Protocol (EIGRP).
Routing Information Protocol (RIP).
Note IS-IS support is provided only on CMTS platforms running Cisco IOS images
that have a “-p-” as part of the image name.
Security Features—DOCSIS 56-bit and 40-bit baseline privacy interface (BPI) Data Encryption Standard (DES).
Security Features—Generic Standard and extended access lists.
Authentication, authorization, and accounting (AAA).
Remote Authentication Dial-In User Service (RADIUS) authentication.
Terminal Access Controller Access Control System Plus (TACACS+).
Cisco IOS firewall enhancements.
Hypertext Transfer Protocol (HTTP) security.
Service Assurance Agent Application-aware agent that monitors network performance by measuring key
service-level agreement (SLA) metrics such as response time, availability, jitter
(interpacket delay variance), connect time, throughput, packet loss, and application
performance; enhanced UDP latency reporting.
Spectrum Management Supports creation of a maximum of 32 cable spectrum groups, allowing:
Multiple upstream ports in a single spectrum group and specifications of configured
channel widths for upstream segments.
Telco-Return Support and
Configurable Termination System
Information (TSI) Messages
Upstream frequencies to be assigned as fixed, single subband, multiple subbands, or
dynamically assigned based on defined thresholds or criteria when using the
Cisco uBR-MC16S cable interface line card.
Dynamic upstream modulation and creation of modulation profiles on
Cisco uBR-MC1xC, Cisco uBR-MC16S, and Cisco uBR-MC28C cable interface
line cards; software monitors the signal-to-noise ratio (SNR) and forward error
correction (FEC) counters in the return path of each upstream port, tracks whether
the current upstream channel signal quality can adequately support a higher
modulation scheme if needed, and proactively adjusts to the more robust Quadrature
Phase-Shift Keying (QPSK) modulation scheme when necessary.
Supports configuring the Cisco CMTS to support a mix of two-way and telco-return
traffic, as well as telco-return only, for plants yet to upgrade segments of their cable plant
or the entire plant; supports termination system information (TSI) messages where the
CMTS administrator can configure an alternate IP address to which the cable
telco-return CM can send its registration requests.
Wiretap Support Offers an interception (wire tapping) mechanism such that user-to-user traffic within a
single CMTS can be captured to meet requirements in countries where regulatory issues
mandate a method by which law enforcement agencies can view all traffic to and from
an individual subscriber.
