Determining RF or Configuration Issues on the CMTS - Cisco 7137-rf The majority of RF plant issues are diagnosed by a low upstream Signal-to-Noise Ratio SNR level, so heavy emphasis is placed on examining this value. This document first states some simple rules to follow, along with an explanation of how the upstream SNR level is calculated. It then illustrates the major configuration parameters and commands to issue to verify the downstream and upstream channels. It finishes with an explanation of the show cable flap-list command to further diagnose RF Cable Modem Termination Systems CMTS - Cisco c enDetermining RF or Configuration Issues on the CMTS 03/Sep/2006 Hardware Troubleshooting the Cisco uBR72xx / uBR7246 VXR Universal Broadband Router 03/Sep/2006 History of the Maximum Upstream Burst Parameter 10/Sep/2018 Cable Modem Termination Systems CMTS - Configuration c enConfiguring DHCP, ToD, TFTP services on Cisco& 39;s CMTS: All-In-One Configuration 10/Sep/2018 Configuring the UBR 7100 in Bridge Mode 04/Oct/2005 Determining RF or Configuration Issues on the CMTS 03/Sep/2006 Troubleshooting Slow Performance in Cable Modem Networks - Cisco c en High CPU Usage on the CMTS. In some circumstances a Cisco CMTS can become overloaded due to a sub-optimal configuration, over use of certain management functions, or a very high number of packets being routed by the CMTS. The best way to determine the CPU usage of a Cisco CMTS is to execute the show process cpu command. The current CPU usage is indi ed on the first line of the output of the command.

The RF switch is definitely needed in the upstream direction. However, in downstream direction if you are doing modular CMTS, then you do not need a RF switch in that direction. In this case redundancy will be provided via gigabit ports. You need a RF switch to switch feasible connection and to protect line card. Q.

Cisco Security Advisory: Cable Modem Termination System cisco-sa-20020617-cmts-md5-bypass The Cisco IOS Software configuration command cable tftp-enforce prohibits a cable modem from registering and coming on line if there is no matching TFTP traffic through the CMTS preceding the registration attempt. This feature has been introduced via CSCdx57688 and can be viewed by registered users of the Cisco website. Cable Monitor Feature - Cisco Community t5 networking-documentsFor a detailed overview of this feature refer to the Cisco CMTS feature guide on Cable Monitor 1 . This guide is intended for lab use specific to SJC-TAC Lab. Cable monitor is similar to the SPAN feature found on Catalyst switches. It allows the user to capture traffic both going to and from a particular device off of the RF Plant.

Silex: Chapter: Load Balancing, Dynamic Channel Change, and 2017 11The Cisco CMTS minimizes packet loss by dupli ing traffic on the new and old RCS until it receives a DBC-RSP from the cable modem. If the Cisco CMTS does not receive the DBC-RSP after six retries of the DBC-REQ, and the RCC change affects the primary downstream channel of the cable modem, the Cisco CMTS reinitializes the cable modem.
