    575 
    576 === Description ===
    577 
    578 OpenFlow-based experimental topologies (see [wiki:OpenFlow/CampusTopology] for example topologies) often need hardcoded ARP entries on participating hosts.  If your MyPLC PlanetLab hosts participate in such a topology, you may need to add static ARP entries.

    587 === Reference ===
    588 
    589 To configure static ARP installation on your system, and to ensure ARP entries are installed after each system boot, follow these steps.
    590 
    591 On each PlanetLab node in your MyPLC installation:
    592 
    593  1. Get the ARP installation shell script (e-mail `gpo-infra@geni.net` if you do not have this script), install it as `<script>`, and make sure it is executable:
    594 {{{
    595 sudo chown root <script>
    596 sudo chmod a+x <script>
    597 }}}
    598 
    599  2. Download the most recent version of the ARP entries config file into `/root`, where `<script>` expects it to be:
    600 {{{
    601 sudo wget -O <arp_file> <arp_url>
    602 }}}
    603 
    604  3. Run the script right away to seed the ARP entries.  This is just:
    605 {{{
    606 sudo <script>
    607 }}}
    608  and you can verify that ARP entries have been added by looking at the arp table, which should now contain many entries:
    609 {{{
    610 arp -a
    611 }}}
    612 
    613  4. Configure the local system startup script to add ARP entries every time the system boots.  GPO infra has an `/etc/rc.local` script which can be used to configure ARP entries after nodemanager successfully runs for the first time (and brings up secondary interfaces configured by PLC).  Install this script as `/etc/rc.d/rc.local`, and ensure it is executable:
    614 {{{
    615 sudo chown root /etc/rc.d/rc.local
    616 sudo chmod a+x /etc/rc.d/rc.local
    617 }}}
