switchd is a controller for software-defined networking (SDN) and is compatible with the OpenFlow protocol.
The options are as follows:
 
 
cachesize
Number of MAC addresses to cache. The default is 4096.
 
 
macro=value
Set a macro to a value. Macros can be referenced in the configuration files.
 
 
Debug mode. Don't detach or become a daemon. This allows for easy monitoring of switchd.
 
 
file
Specifies the configuration file. The default is /etc/switchd.conf.
 
 
Check that the configuration is valid, but don't start the daemon.
 
 
timeout
Timeout in seconds for learned MAC addresses. The default is 240 seconds.
 
 
Verbose mode. Multiple -v options increase the verbosity.

/etc/switchd.conf
Default configuration file.
