Rspec with one group
Rspec with multiple groups
Rspec with groups and datapaths
Rspec for ICMP traffic from all the datapaths
Rspec to get all traffic for an IP subnet including ARP

If you have written any interested OFv3 rspecs, feel free to add them at the bottom of this page and help others:-)

A complete example rspec can be found here example rspec

Rspec with one group

If you want to apply your packet filters to the same set of dpids, then you just need to create one group and use it in all your matches. In this example we only match on Ethernet addresses.

           <openflow:packet />
         <openflow:match>

    </openflow:sliver>

</rspec>

Rspec with multiple groups

If you need to apply different packet filters in different datapath sets, then you can create multiple groups and use them as needed in your matches. In this example we want all ARP packets of a specific vlan.

Rspec with groups and datapaths

If for only one of your matches you need a different set of datapaths, you don't need to create a group you can just add the datapaths directly in your match. In this example we match all ssh (TCP port 22) traffic.
