Question

如何在实际交换机上启用SDN？我已经使用迷你网成功模拟了SDN，但是当我使用实际的交换机时，我无法控制流入交换机的流量而无法ping主机。我正在使用ODL控制器和Cisco 3650交换机。有没有人成功做到了？

验证OpenFlow的Cisco插件

摘要步骤

show openflow copyright
show openflow switch switch-id
show openflow switch switch-id controllers [ stats ]
show openflow switch switch ports
show openflow switch-id flows [ configured | controller | default | fixed | pending | pending-del ] [ brief | summary]
show openflow switch switch-id stats
show interfaces type number counter
show running-config | section openflow
show openflow hardware capabilities

示例：使用物理接口指定到控制器的路由

Switch> enable
Switch# configure terminal
Switch(config)# interface GigabitEthernet1/0/1
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.0.1.4 255.255.255.0
Switch(config-if)# exit
Switch(config)# ip route 0.0.0.0 0.0.0.0 10.0.1.6
Switch# copy running-config startup-config
Switch(config)# exit

示例：使用管理界面指定到控制器的路由

Device> enable
Switch# configure terminal
Switch(config)# interface GigabitEthernet0/0
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.0.1.4 255.255.255.0
Switch(config-if)# exit
Switch(config)# ip route vrf mgmtVrf 0.0.0.0 0.0.0.0 10.0.1.6
Switch# copy running-config startup-config
Switch(config)# exit

示例：用于OpenFlow逻辑交换机配置的Cisco插件（默认VRF）

Switch> enable
Switch# configure terminal
Switch(config)# onep
Switch(config-onep)# exit

Switch(config)# openflow
Switch(config-ofa)# switch 1

! Specifies the pipeline that enables the IP Forwarding Table.
Switch(config-ofa-switch)# pipeline 1
Switch(config-ofa-switch)# tls trust-point local local-trustpoint-name remote remote-trustpoint-name
Switch(config-ofa-switch)# max-backoff 5
Switch(config-ofa-switch)# probe-interval 5
Switch(config-ofa-switch)# rate-limit packet-in 300 burst 50
Switch(config-ofa-switch)# controller ipv4 10.0.1.6 port 6323 security none
Switch(config-ofa-switch)# datapath-id 0x222

! Adding an interface to the Cisco Plug-In for OpenFlow logical switch.
Switch(config-ofa-switch)# of-port interface GigabitEthernet1/0/23
Switch(config-ofa-switch)#end
Switch# copy running-config startup-config

示例：为OpenFlow逻辑交换机（管理VRF）配置Cisco插件

Switch> enable
Switch# configure terminal
Switch(config)# onep
Switch(config-onep)# exit

Switch(config)# openflow
Switch(config-ofa)# switch 1
Switch(config-ofa-switch)# pipeline 1

! Specifying a controller that is part of a VRF.
Switch(config-ofa-switch)# controller ipv4 10.0.1.6 port 6323 vrf mgmtVrf security none

! Adding an interface to the Cisco Plug-In for OpenFlow logical switch.
Switch(config-ofa-switch)# of-port interface GigabitEthernet1/0/23
Switch(config-ofa-switch)# end
Switch# copy running-config startup-config
