Eu quero filtrar os seguintes campos de cada dispositivo: ID do dispositivo, endereço IP, interface, porta ID (porta de saída)

Eu tentei (sem sucesso) pesquisar toda vez que a palavra "ID do dispositivo" aparece e salve até que "ID da porta" apareça para obter um arquivo como este:

Você poderia me ajudar com isso?

Você conhece uma maneira melhor de capturar essa informação?

Isso imprimirá qualquer linha que tenha correspondência para os campos que você está procurando: 

awk '/Device ID|IP address|Interface|Port ID/ { print }' /path/to/input

Você pode realizar o mesmo com grep , sed e outras ferramentas semelhantes.

Você pode até ficar um pouco mais chique: 

grep -Eo '(Device ID|IP address|Interface|Port ID): [^ ]+' /path/to/input

Você tem a opção de usar o egrep ao invés do awk? 

egrep "Device|IP\ address|Interface|Port\ ID" input-file.txt

Se não for um arquivo de log de muitos gigabytes, 

 perl -0ne 'for( /Device ID.*?Port ID.*?\n/sg ){ print "-"x 20,"\n$_\n"}' file
