以下命令：

~$ lsb_release -a
No LSB modules are available.

创建两个新的第 2 层接口（ovs-system& bridge1），如下所示：

~$ 
~$ 
~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether ff:ff:ff:19:f1:f6 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 10:0b:a9:0f:ff:f4 brd ff:ff:ff:ff:ff:ff
    inet 192.168.68.103/24 brd 192.168.68.255 scope global dynamic noprefixroute wlp2s0
       valid_lft 6717sec preferred_lft 6717sec
    inet6 fe80::6ce4:7dff:7ff8:3fff/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
6: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 6e:ed:1a:5e:a7:d1 brd ff:ff:ff:ff:ff:ff
7: mybridge: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 92:21:d4:14:9f:41 brd ff:ff:ff:ff:ff:ff
~$

ovs-system上面的接口列表中有什么？
下图中桥接器()的端口( Port "mybridge")和接口( )之间有什么不同？Interface "mybridge"Bridge "mybridge"
