ofctl_script is openflow control shell scripts with Ryu SDN framework This scripts use Ryu application ofctl_rest.py.
Install Ryu SDN framework. Please see http://osrg.github.io/ryu/ .
Clone the source code.
$ git clone git://github.com/hibitomo/ofctl_script
$ git clone git://github.com/osrg/ryu.git
Install necessary package
$ sudo apt-get install jq
Run OpenFlow Switch and check the datapath_id.
Run Ryu application ofctl_rest.py
$ cd ryu
$ ryu-manager [your Ryu application] ryu/app/ofctl_rest.py
Configure the dataplane id and url with ofctl.conf.
$ cd ofctl_script
$ head ofctl.conf -n 2
dpid=1
url=127.0.0.1:8080
Or you can use options -d
and -u
to the scripts.
$ ./show_flow -d 1 -u 127.0.0.1:8080
show_flow can show and dump flow rules.
$ ./show_flow
$ ./show_flow > [dump file]
If you want to see other information in flow rules, you can configure them with ofctl.conf.
add_flow can set a flow rule.
$ ./add_flow '{"table_id":0,"priority":110,"actions":["OUTPUT:1"],"match":{"dl_dst":"00:00:00:01:02:03/ff:ff:ff:ff:ff:ff","in_port":2}}'
$ ./add_flow -t group '{"type":"ALL","group_id":4,"buckets":[{"actions":["OUTPUT:1"]}]}' # group_table
$ ./add_flow -t meter '{"meter_id":1,"flags":["KBPS"],"bands":[{"type":"DROP","rate":1000}]}' # meter_table
And It can set multi flow rules with dump file created show_flow.
$ ./show_flow > flow_dump
$ ./add_flow < flow_dump
If you dump flow rules with grep, you have to configure ofctl.conf to show table_id
.
Tips: flow integration tests
$ ./add_flow < flow_dump_appA
$ ./add_flow < flow_dump_appB
$ ### Your flow integration test ###
del_flow can delete the flow rule.
$ ./del_flow '{"table_id":0,"priority":110,"actions":["OUTPUT:1"],"match":{"dl_dst":"00:00:00:01:02:03/ff:ff:ff:ff:ff:ff","in_port":2}}'
$ ./del_flow -t group '{"type":"ALL","group_id":4,"buckets":[{"actions":["OUTPUT:1"]}]}' # group_table
$ ./del_flow -t meter '{"meter_id":1,"flags":["KBPS"],"bands":[{"type":"DROP","rate":1000}]}' # meter_table
And It can delete multi flow rules with dump flow created show_flow.
$ ./show_flow > flow_dump
$ ./del_flow < flow_dump
If you dump flow rules with grep, you have to configure ofctl.conf to show table_id
.
Tips: Delete all flow rules
$ ./show_flow | ./del_flow
You can set the datapath_id with lagopus.dsl.
channel channel01 create -dst-addr 127.0.0.1 -protocol tcp
controller controller01 create -channel channel01 -role equal -connection-type main
interface interface0 create -type ethernet-dpdk-phy -port-number 0
interface interface1 create -type ethernet-dpdk-phy -port-number 1
port port01 create -interface interface0
port port02 create -interface interface1
bridge bridge01 create -controller controller01 -port port01 1 -port port02 2 -port -dpid 0x1
bridge bridge01 enable
You can set the datapath_id by ovs-vsctl.
# ovs-vsctl set bridge br0 other-config:datapath-id=0000000000000001
