Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
"Global configuration mode" provides commands to change the system's configuration, and "interface configuration mode" provides commands to change the configuration of a specific interface. All commands are assigned a privilege level, from 0 to 15, and can only be accessed by users with the necessary privilege. Through the CLI, the commands ...
The configuration software of choice is then used to configure the persistent configuration which is applied on boot. It is also possible to configure Linux networking ad-hoc using the ip command from the iproute2 package. The following command can be used to configure the route using ip: [10]
In the Cisco IOS, [1] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF. To indicate what IP addresses should be permitted or denied in access control lists (ACLs). A wildcard mask can be thought of as an inverted subnet mask.
Cisco's first implementation of this protocol was introduced in version 10 of their router software. [1] It is implemented through the use of the router configuration commands ip helper-address and ip forward-protocol.
It is based on Wind River Linux and is inter-operable with other Cisco operating systems. [citation needed] The command-line interface of NX-OS is similar to that of Cisco IOS. [2] Recent NX-OS has both Cisco-style CLI and Bash shell available. On NX-OS 7.0(3)I3, the output from uname with the -a command line argument might look like the text ...
Verifying the configuration of the administrative distance is done on Cisco equipment using the show ip route command in privileged exec mode on the console of the Cisco router. [8] [9] In the example shown below, the administrative distance is 1.
IOS XE is a release train of Cisco Systems' widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. [2]It is built on Linux [3] [4] and provides a distributed software architecture that moves many operating system responsibilities out of the IOS process [5] [6] and has a copy of IOS running as a separate process.
