奇怪的ip命令輸出

當我打電話時，ip addr show我會得到所有介面及其 IP 地址的輸出（查看eth7）：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:e9:3d:aa brd ff:ff:ff:ff:ff:ff
   inet 172.11.98.248/16 brd 172.11.255.255 scope global eth1
3: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc cbq state UP qlen 1000
   link/ether 00:1c:42:c6:d0:c4 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.242/19 brd 10.28.127.255 scope global eth2
4: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:56:14:28 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.249/24 scope global eth4
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:03:06:77 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.230/19 brd 10.28.127.255 scope global eth3
6: eth7: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
   link/ether 00:1c:42:4d:cb:d7 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.231/24 scope global eth7
   inet 192.168.13.0/18 scope global eth7
7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
   link/ether 00:1c:42:81:0a:a4 brd ff:ff:ff:ff:ff:ff
8: eth6: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
   link/ether 00:1c:42:5c:12:40 brd ff:ff:ff:ff:ff:ff
9: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/ether b2:c1:df:b1:29:c7 brd ff:ff:ff:ff:ff:ff
   inet 10.47.130.2/24 brd 10.47.130.255 scope global br0
10: br1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/ether 52:b4:3a:90:f2:05 brd ff:ff:ff:ff:ff:ff
11: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/void 

但是當我呼叫相同的命令時ip addr show up，但只針對升級介面，我得到了奇怪的結果：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   inet 127.0.0.1/8 scope host lo
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:e9:3d:aa brd ff:ff:ff:ff:ff:ff
   inet 172.11.98.248/16 brd 172.11.255.255 scope global eth1
3: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc cbq state UP qlen 1000
   link/ether 00:1c:42:c6:d0:c4 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.242/19 brd 10.28.127.255 scope global eth2
4: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:56:14:28 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.249/24 scope global eth4
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 00:1c:42:03:06:77 brd ff:ff:ff:ff:ff:ff
   inet 10.28.98.230/19 brd 10.28.127.255 scope global eth3
   inet 10.28.98.231/24 scope global eth7
   inet 192.168.13.0/18 scope global eth7
9: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/ether b2:c1:df:b1:29:c7 brd ff:ff:ff:ff:ff:ff
   inet 10.47.130.2/24 brd 10.47.130.255 scope global br0
10: br1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/ether 52:b4:3a:90:f2:05 brd ff:ff:ff:ff:ff:ff
11: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
   link/void 

我期望關閉的介面會從輸出中消失。但是，對我來說有點奇怪，我看到不僅它們消失了，而且以前分配給的 IP 地址192.168.13.0/18現在10.28.98.231/24也eth7分配給了eth3。

這是正常行為嗎？為什麼會這樣？為什麼這些 IP 地址被分配給eth3介面而不是其他介面？

這是一個錯誤。已經有一個更新檔，所以你可以期待它在下一個版本中得到修復。感謝wurtel報告它。
