Olt Pre Provisioning
    [Documentation]     Olt Pre Provisioning
    ...                 This test preprovisions a ponsim-OLT with given IP address and TCP port 
    ...                 and then enables both it and a number of ponsim-ONUs with predefined IP/port
    ...                 information. It then verifies that all the physical and logical devices are ACTIVE

Radius Authentication

    ...                 This test attempts to perform a Radius Authentication from the RG
    ...                 It uses the wpa_supplicant app to authenticate using EAPOL.

Dhcp IP Address Assignment on RG
    [Documentation]     DHCP assigned IP Address
    ...                 A DHCP server is configured and Activated on Onos. We need to change
    ...                 the Firewall rules so as to allow packets to flow between RG and OLT/ONU
    ...                 We also must add a second DHCP flow rule in onos in the direction from NNI
    ...                 by calling 'add subscriber access' on onos. We then deassign the default
    ...                 IP address granted to RG upon instantiating the RG pod. Finally we invoke
    ...                 'dhclient' on RG to request a DHCP IP address.

    ...                 Destination Host Unreachable message. We then invoke tcpdump on 'pon1'
    ...                 network looking for ARP request from RG IP address. These packets should
    ...                 be double tagged with different s and c Tags but matching tag configuration
