Um comando interessante para ser utilizado em roteadores e switches Cisco é o terminal exec prompt timestamp.
Após adicionar este comando à configuração, toda vez que um comando show for utilizado, a saída será precedida pela utilização da CPU e pela hora atual do equipamento.
Exemplo:
RTBrainwork01#terminal exec prompt timestamp
RTBrainwork01#sh interface f0/0
