Cisco IOS (originalmente Internetwork Operating System) é o software usado na grande maioria dos roteadores Cisco Systems e atuais switches de rede da Cisco (versões anteriores usavam o CatOS).<br />
<br />
IOS é um pacote de roteamento, switching, internetworking e funções de telecomunicações totalmente integrado com um sistema operacional de computador multi-tarefa.<br />
<br />
 A interface de linha de comando do IOS fornece um conjunto fixo de palavras de comando - o conjunto disponível é determinado pelo "modo" e o nível de privilégio do usuário atual. "Modo de configuração global" fornece comandos para mudar a configuração do sistema, e "modo de configuração de interface" fornece comandos para mudar a configuração de uma interface específica. Todos os comandos são atribuídos a um nível de privilégio, variando de 0-15, e só podem ser acessados por usuários com o privilégio necessário. Através do linha de comando, os comandos disponíveis para cada nível de privilégio pode ser definido.<br />
