How to change Cisco Console Speed or Buad Rate on Cisco Devices

To connect Cisco device using Console port using any terminal emulation program needs to be set to the following specifications: Baud rate: 9600 bps, Data bits: 8, Parity: None, Stop bits: 1, Flow control: None. These are the default settings required for both the console and the auxiliary ports. Advantages with Cisco Console Speed Cisco devices console port default baud rate is 9600 bps, some Router models will allow you to increase the console speed up to 115200. Increasing the console speed has its advantages. It will enhance the response time when typing at the console and will allow console messages to be sent to the console faster. It is very useful when you are upgrading the IOS through the console port from ROMmon Mode or Privilege EXEC Mode. It increases the transfer rate and reduces the transfer time. Change Console Speed from Cisco Router Line Console Mode: To change […]

How to Stop Cisco Console Logging messages

When you logged into a Cisco Router, Switch and other Devices via console port using HyperTerminal or other emulator software, the console messages make you hard to see the show commands output and enter new commands for configuration. Disable/Stop Cisco Console Logging Messages There is a command to turn off the messages on the console session. Log on to your Cisco Router or Switch and go to Global configuration mode by entering configuration terminal then enter  no logging console command.

Configure Logging Synchronous on Cisco Console to Minimize Logging Interruptions

Logging Synchronous on Cisco Router/Switch When you are working on the Cisco Router or Catalyst Switch console, sometimes it will display the messages even you were typing commands. It would be annoying to have the console or telnet logs to pop in between your commands. This can be even more irritating when it is busy Switch or a Router displaying messages continuously. You can use logging synchronous command under the console or vty line configuration mode to minimize this. Router still displays its messages but will redisplay the command you were typing on the line when it’s done. You can also turn off logging messages completely by using the command no logging console under global configuration mode. Note: This may cause you to miss some important messages from the Router. You can modify this command by specifying the severity level of the message you want to turn off. Configure  Logging […]

How to Upload Cisco IOS from ROMmon mode using xmodem via console cable

This document explains how to upload Cisco IOS® software onto Cisco Routers or Switches  from ROMmon mode using xmodem via Cisco console cable. This is used in disaster recovery situations where the Router Cisco IOS software is corrupted or crashed. I suggest you to use this procedure only where there are no Trivial File Transfer Protocol (TFTP) server software or RJ-45 network connections, and a direct PC connection to the router’s console port via console cable is the only viable option. Because this procedure depends on the console speed of the Router and the serial port of the PC, it can take a long time to download an image. The information in this document is based on Cisco IOS Software Release 12.1 and later. Xmodem command syntax on ROMmon Mode via Console cable xmodem [-c] [-y] [-e] [-f] [-r] [-x] [-s data-rate] In order to find out the syntax and […]

Cisco Console RJ45 to DB9 Cable Pinout details

The console port on Cisco IOS Routers or Switches is asynchronous serial port. The console port is configured as data terminal equipment (DTE). For Cisco 1000, 1600, 2500, 2600, and 3600 Series Routers, the console port use RJ-45 connectors. Adapters are available for connect RJ45 cable  to PC terminals. Generally we use the rollover cable +DB9 Terminal Adaptor to connect Router console port to Computer COM port. The below table shows the console port pinouts for the RJ-45 connector and  Pinout details from Rollover RJ45 cable to PC DB9 Female connector. Use this cable to configure a Cisco Router using the Console port on the Router. Below figure shows the Cisco Console port connectivity with RJ45 Rollover cable + DB-9 Adapter               Cisco Console port – Rollover – DB9 Cable Pinout and Signaling details This table shows the pinout details for the Cisco Console  […]
