In this section you will learn about the router commands, configurations, privileged mode commands, routing protocols, cisco labs and network configurations.

There are hundreds of basic and advance level commands of a router. It is not easy to remember all the commands. But some commands are frequently used and can be remembered with some practice. I have provided a list of the most commonly used commands based on their features and usage. You will find here some basic terminology of a router.

Routing: Routing is a process of moving the data (packets) through an inter network. Routing performs the two basic tasks. Define the paths for a packet and then forward the packets on the basis of defined paths. Routing can also be defined as the communication between two or more logically and physical networks and this communication (packet transfer) is brought by a router.

First of all you should remember the keyboard shortcuts of a router.

Configuring the Router

You will be able to learn the basic commands for configuring a router.sh running-config - details the running configuration file (RAM)sh startup-config - displays the configuration stored in NVRAMsetup - Will start the the automatic setup; the same as when you first boot the routerconfig t - use to execute configuration commands from the terminalconfig mem - executes configuration commands stored in NVRAM; copies startup-config to running-config

config net - used to retrieve configuration info from a TFTP servercopy running-config startup-config - copies saved config in running config (RAM) to NVRAM or "write memory" for IOS under ver.11copy startup-config running-config - copies from non-volatile (NVRAM) to current running config (RAM)boot system flash - tells router which IOS file in flash to boot fromboot system tftp - tells router which IOS file on the tftp server to boot fromboot system rom - tell router to boot from ROM at next bootcopy flash tftp - Copies flash to tftp servercopy tftp flash - Restores flash from tftp servercopy run tftp - Copies the current running-config to tftp servercopy tftp run - Restores the running-config from tftp server

General Commands

Here is a list of the general commands. These are the basic level commands and most commonly usedno shutdown - (enables the interface)reload - restarts the routersh ver - Cisco IOS version, uptime of router, how the router started, where system was loaded from, the interfaces the POST found, and theconfiguration register sh clock - shows date and time on routersh history - shows the history of your commandssh debug - shows all debugging that is currently enabledno debug all - turns off all debuggingsh users - shows users connected to routersh protocols - shows which protocols are configuredbanner motd # Your customized message here # - Set/change bannerhostname - use to configure the hostname of the routerclear counters - clear interface counters

Privileged Mode commands of a router

Learn how to work in the privileged mode of a router.enable - get to privileged modedisable - get to user modeenable password - sets privileged mode passwordenable secret - sets encrypted privileged mode passwordSetting Passwords on routerHere you will be able to learn how to set the password on a router.enable secret - set encrypted password for privileged accessenable password - set password for privileged access (used when there is no enable secret and when using older software)Setting the password for console access:(config)#line console 0(config-line)#login

(config-line)#password Set password for virtual terminal (telnet) access (password must be set to access router through telnet):(config)#line vty 0 4(config-line)#login(config-line)#password Set password for auxiliary (modem) access:(config)#line aux 0(config-line)#login(config-line)#password

Router Processes & Statistics

By these command you can see the statistics and different processes of the router.sh processes - shows active processes running on routersh process cpu - shows cpu statisticssh mem - shows memory statisticssh flash - describes the flash memory and displays the size of files and the amount of free flash memorysh buffers - displays statistics for router buffer pools; shows the size of the Small, Middle, Big, Very Big, Large and Huge Bufferssh stacks - shows reason for last reboot, monitors the stack use of processes and interrupts routines

IP Commands

Here is a list of the IP CommandsConfigure IP on an interface:int serial 0ip address 157.89.1.3 255.255.0.0int eth 0ip address 2008.1.1.4 255.255.255.0

Other IP Commands:

sh ip route - view ip routing tableip route [administrative_distance] - configure a static IP routeip route 0.0.0.0 0.0.0.0 - sets default gatewayip classless - use with static routing to allow packets destined for unrecognized subnets to use the best possible routesh arp - view arp cache; shows MAC address of connected routersip address 2.2.2.2 255.255.255.0 secondary - configure a 2nd ip address on an interfacesh ip protocol

CDP Commands (Cisco Discovery Protocol uses layer 2 multicast over a SNAP-capable link to send data):

sh cdp neighbor - shows directly connected neighborssh cdp int - shows which interfaces are running CDPsh cdp int eth 0/0 - show CDP info for specific interfacesh cdp entry - shows CDP neighbor detailcdp timer 120 - change how often CDP info is sent (default cdp timer is 60)cp holdtime 240 - how long to wait before removing a CDP neighbor (default CDP holdtime is 180)sh cdp run - shows if CDP turned onno cdp run - turns off CDP for entire router (global config)no cdp enable - turns off CDP on specific interface

IPX Commands

Enable IPX on router:ipx routingConfigure IPX + IPX-RIP on an int:int ser 0ipx network 4A

Other Commands:

sh ipx route - shows IPX routing tablesh ipx int e0 - shows ipx address on intsh ipx servers - shows SAP tablesh ipx traffic - view traffic statisticsdebug ipx routing activity - debugs IPS RIP packetsdebug ipx sap - debugs SAP packets

Routing Protocols

RIP, IGPR and OSPF are the routing protocols and here is a list of the commands for the working on the routing protocols.Configure RIP:router ripnetwork 157.89.0.0network 208.1.1.0Other RIP Commands:debug ip rip - view RIP debugging infoConfigure IGRP:router IGRP 200network 157.89.0.0network 208.1.1.0Other IGRP Commands:debug ip igrp events - view IGRP debugging infodebug ip igrp transactions - view IGRP debugging infoAccess Lists

WAN Configurations Commands

Networking over WAN is the main functionality of a router. The most common use of a router is for the WAN connectivity. Here is a list of the commands for the different methods of the WAN connectivity.

PPP Configuration

Point to point protocol is a method for the WAN connectivity and you will find here some commands of PPP.encapsulation pppppp authentication ppp chap hostname ppp pap sent-username sh int ser 0 - use to view encapsulation on the interface
