How to configure openflow
Setup CAM
#configure (conf)#cam-acl l2acl 2 ipv4acl 2 ipv6acl 0 ipv4qos 0 l2qos 1 l2pt 0 ipmacacl 0 vman-qos 0 ecfmacl 0 openflow 8 (conf)#cam-acl-vlan vlanopenflow 1 vlaniscsi 1 vlanaclopt 0 (conf)#exit |
Reboot the switch
#reload |
Create openflow instance
#configure (conf)#openflow of-instance 1 (conf-of-instance-1)#controller 1 10.11.44.5 tcp [ change to your controller ip ] (conf-of-instance-1)#flow-map l2 enable (conf-of-instance-1)#flow-map l3 enable (conf-of-instance-1)#interface-type any (conf-of-instance-1)#multiple-fwd-table enable (conf-of-instance-1)#of-version 1.3 (conf)#exit |
Setup interfaces
(conf)#interface TenGigabitEthernet 0/0 [ change to your network ports] (conf-if-te-0/0)#of-instance 1 (conf-if-te-0/0)#no switch-port (conf-if-te-0/0)#no shutdown (conf)#exit |
Enable the openflow instance
(conf)#openflow of-instance 1 (conf-of-instance-1)#not shutdown (conf-of-instance-1)#exit |
