===== Trabalhando com archive(arquivos de pacotes) =====

Os archives são como container de arquivos agrupamento de arquivos.

  * archive tar /create - Cria um arquivo e adiciona arquivos nele
  * archive tar /table - Mostra o conteudo do arquivo
  * archive tar /xtract - Extrai arquivos.

<code bash>
switch# archive tar /create tftp://172.20.10.30/saved flash:/new-configs
</code>

<code bash>
switch# archive tar /table flash:/new-configs
</code>

<code bash>
switch# archive tar /xtract tftp://172.20.10.30/saved flash:/new-configs
</code>
