packet_in handler

Given

I set the environment variables to:

variable	value
TREMA_LOG_DIR	.
TREMA_PID_DIR	.
TREMA_SOCKET_DIR	.

And

a file named "trema.conf" with:

vswitch { datapath_id 0xabc }
vhost('host1') { ip '192.168.0.1' }
vhost('host2') { ip '192.168.0.2' }
link '0xabc', 'host1'
link '0xabc', 'host2'

Scenarios

@sudo invoke packet_in handler

Given

a file named "packet_in_controller.rb" with:

class PacketInController < Trema::Controller
  def packet_in(dpid, message)
    logger.info "new packet_in (dpid = #{dpid.to_hex})"
  end
end

And

I successfully run trema run packet_in_controller.rb -c trema.conf -d

And

sleep 3

When

I successfully run trema send_packets --source host1 --dest host2

Then

the file "PacketInController.log" should contain "new packet_in (dpid = 0xabc)"

@sudo invoke packet_in handler (OpenFlow 1.3)

Given

a file named "packet_in_controller.rb" with:

class PacketInController < Trema::Controller
  def switch_ready(dpid)
    send_flow_mod_add(
      dpid,
      match: Match.new,
      instructions: Apply.new(SendOutPort.new(:controller))
    )
  end

  def packet_in(dpid, message)
    logger.info "new packet_in (dpid = #{dpid.to_hex})"
  end
end

And

I successfully run trema run packet_in_controller.rb -c trema.conf --openflow13 -d

And

sleep 3

When

I successfully run trema send_packets --source host1 --dest host2

Then

the file "PacketInController.log" should contain "new packet_in (dpid = 0xabc)"
