Open switch得到port相关信息的命令

1.查看port所属bridge

zg@cp42:~$ sudo ovs-vsctl port-to-br qvo500b9699-47
br-int

2.查看一个br下的所有port，port的排列顺序为创建时间先后顺序

stack@cp42:/home/zg/kvm$ sudo ovs-ofctl show br-int

3.为一个port配置QoS

 

stack@cp42:~/data/nova/instances/locks$ sudo ovs-vsctl -- set port qvo5561051d-68 qos=@newqos -- --id=@newqos create qos type=linux-htb other-config:max-rate=100
53250b57-beff-45c0-9d1d-3a2e2d509ada

 这里是为qvo5561051d-68端口配置一条最大rate不超过100的QoS，返回的是这个QoS的uuid

 

 这时，在查看port qvo5561051d-68的信息，就能看到它所应用的qos的uuid

stack@cp42:~/data/nova/instances/locks$ sudo ovs-vsctl list port qvo5561051d-68_uuid               : 6dbd2080-d2b2-42bc-8d57-f6a26e79f91d
bond_downdelay      : 0
bond_fake_iface     : false
bond_mode           : []
bond_updelay        : 0
external_ids        : {}
fake_bridge         : false
interfaces          : [822b735b-c428-49bd-968f-44d329046f73]
lacp                : []
mac                 : []
name                : "qvo5561051d-68"
other_config        : {}
qos                 : 53250b57-beff-45c0-9d1d-3a2e2d509ada
statistics          : {}
status              : {}
tag                 : []
trunks              : []
vlan_mode           : []

使用list qos + qos uuid 命令能显示出这条QoS的详细信息

stack@cp42:~/data/nova/instances/locks$ sudo ovs-vsctl list qos 53250b57-beff-45c0-9d1d-3a2e2d509ada
_uuid               : 53250b57-beff-45c0-9d1d-3a2e2d509ada
external_ids        : {}
other_config        : {max-rate="100"}
queues              : {}
type                : linux-htb
