iface eth0 inet manual和iface eth0 inet static有什么区别？

iface eth0 inet manual和之间有什么区别iface eth0 inet static？

谢谢

iface eth0 inet static：为eth0定义一个静态IP地址

iface eth0 inet manual：创建根本没有IP地址的网络接口。通常由作为桥接或聚合成员的接口，或在其上配置了VLAN设备的接口使用

# Set up an interface to read all the traffic on the network. This 
# configuration can be useful to setup Network Intrusion Detection
# sensors in 'stealth'-type configuration. This prevents the NIDS
# system to be a direct target in a hostile network since they have
# no IP address on the network. Notice, however, that there have been
# known bugs over time in sensors part of NIDS (for example see 
# DSA-297 related to Snort) and remote buffer overflows might even be
# triggered by network packet processing.

# Set up an interface which will not be allocated an IP address by
# ifupdown but will be configured through external programs. This
# can be useful to setup interfaces configured through other programs,
# like, for example, PPPOE scripts.
