Examples with Ethernet org.onlab.packet.Ethernet used on opensource projects

Example 6 with Ethernet

use of org.onlab.packet.Ethernet in project aaa by opencord.

the class SocketBasedRadiusCommunicator method handlePacketFromServer.

// in the socket base case we don't care about packets coming from the server as nothing meaningful will be
// received from the southbound
