+== Getting the nodes to work ==
+
+=== IP8800 configurations: setting port speed (7/17) ===
+The default port setting is autonegotiation. The port speeds can be forced to different speeds, but this breaks imaging especially if the nodes aren't willing to negotiate to 1Gbps. If set to autonegotiate at a certain speed, the port will be shut down unless the host also negotiates to that speed. the nodes seemed to have issues even if the port was purely set to function at 1Gbps and not to autonegotiate.
+
+=== disabling '''all''' forms of spanning tree ===
+Spanning tree can be disabled with the command 
+
+ no spanning-tree
+
+at the configuration prompt. Another similar protocol for VLANS, per-VLAN sanning tree plus (PVST+) is started automatically whenever VLANs are created. reference on PVST+: http://www.javvin.com/protocol/PVST+.html 
+ 
+PVST+ seems to seriously disrupt communication between the nodehandler and agent, so it was disabled on the switch.
