Cisco packet tracer commands

Cisco packet tracer commands and their use

Packet tracer allows us to practice various Cisco commands through simulation. Packet tracer supports lots of commands however it does not support some commands.

Updated versions of the packet tracer support more commands so with every new release of the packet tracer, we can see more supported commands and better features however it has enough commands to prepare for CCNA certification.

To check all the commands we have to practice of real Cisco device or we can use GNS3 software which is powerful emulation software that emulates a real router. It uses a real Cisco IOS to emulate the device so we can see all the available commands on the Cisco device.

GNS3 needs more learning curve and it does not support full switch commands.

Following are the packet tracer commands that we can use to configure the network in packet tracer.

Routing commands

R1# configure terminal (enter global configuration mode)

R1(config)# hostname NAME

R1(config)# service password-encryption

R1(config)# enable secret PASSWORD

R1(config)# no ip domain-lookup

R1(config)# banner motd MESSAGE

R1(config)# line console 0

R1(config-line)# password PASSWORD

R1(config-line)# login

R1(config-line)# logging synchronous

R1(config-line)# exec-timeout 1 1

R1(config)# line vty 0 4

R1# copy running-config startup-config

Switch Commands

S1(config)# interface vlan 1

S1(config-if)# description (Anything we want)

S1(config-if)# ip address (assign an IP address)

S1(config-if)# no shutdown

S1(config-if)# exit

S1(config)# ip default-gateway

S1(config)# enable secret SECRET

S1(config)# line vty 0 15

S1(config-line)# password PASSWORD

S1(config-line)# login

S1(config-line)# transport input telnet

VLAN commands

S1(config)# vlan 10

S1(config-vlan)# name Market

S1(config)# interface fa0/1

S1(config)# interface range fa0/1 – 20

S1(config-if)# switchport mode access

S1(config-if)# switchport access vlan 10

Above are the common commands available in the packet tracer, we can use these commands to create networks and configure devices.

Packet tracer includes lots of other commands required to prepare for the CCNA certification however for higher certification, you can try GNS3.

The packet tracer is lacking in security commands and some other advanced features like firewall, voice etc.
