Detailed Description

User-space switch.

Constructor & Destructor Documentation

◆ __init__()

def mininet.node.UserSwitch.__init__ (   self,
  name,
  dpopts = '--no-slicing',
**  kwargs 
)

Init.

Parameters
namename for the switch
dpoptsadditional arguments to ofdatapath (–no-slicing)

Reimplemented from mininet.node.Node.

Member Function Documentation

◆ start()

def mininet.node.UserSwitch.start (   self,
  controllers 
)

Start OpenFlow reference user datapath.

Log to /tmp/sN-{ofd,ofp}.log.

Parameters
controllerslist of controller objects

◆ stop()

def mininet.node.UserSwitch.stop (   self,
  deleteIntfs = True 
)

Stop OpenFlow reference user datapath.

Parameters
deleteIntfsdelete interfaces? (True)

Reimplemented from mininet.node.Switch.

◆ TCReapply()

def mininet.node.UserSwitch.TCReapply (   intf)
static

Unfortunately user switch and Mininet are fighting over tc queuing disciplines.

To resolve the conflict, we re-create the user switch's configuration, but as a leaf of the TCIntf-created configuration.
