Hi controller experts,

After checking current GUI/NB API, I have got couple of questions:

-          Static route: What exactly is happening when I add a static route pointing to a known host in Host Tracker? I was expecting some flows were recreated to reach destination but this does not look the case…

-          SPAN port: what is a SPAN port?

Thanks in advance

Luis

The Static Route feature is used to resolve the MAC address of a next-hop gateway on an adjacent, non-OpenFlow switch.  It essentially resolves and tracks a next-hop gateway MAC address for use in future flow programming.  The feature itself doesn’t program anything on a switch.

SPAN = Switched Port Analyzer; a term used for a port interface that connects to a promiscuous analysis device (packet capture, DLP, etc.).  In the context of ODL, this allows you to define a port as a SPAN port (i.e. connected to an analysis device), which can be used later for replicating flow traffic.  Again here, configuring the feature in-an-of itself doesn’t program anything on a switch.

Regards,

Zach

Hi Zach, thanks very much for your quick answer.
