Message Protocols—Select one or more protocols to construct packets for fault analysis.
Options are:
− TCP
− UDP
− ICMP
− DHCP
When multiple protocols are selected, SDNM considers an OpenFlow instance unreachable if
packets in the instance failed to be forwarded through any of the protocols.
4. Click Trouble Analysis to start fault analysis.
The analysis results are displayed in a topology and a list.
{
The topology displays the OpenFlow instances in different colors according to their reachability
states:
− Green—The OpenFlow instance is reachable.
− Red—The OpenFlow instance is unreachable.
− Blue—The state of the OpenFlow instance is unknown.
The analysis result list displays the analysis result for each OpenFlow instance involved in
the service flow. Faulty instances are highlighted in red. Trouble analysis results include:
− Type—Protocol used for fault analysis.
− Analysis Process—Action that is taken to analyze the fault.
− Analysis Result—Result of the action.
5. If the service flow is unreachable, a Root Cause Analysis button is displayed. Click the button to
start root cause analysis.
SDN analyzes the faulty service flow in various aspects according to the information reported by
the controller, and displays the analysis results in a topology and a list.
{
The topology displays the OpenFlow instances in different colors according to their states:
− Green—The OpenFlow instance is normal.
− Red—The OpenFlow instance is faulty.
{
The root cause analysis result list displays the analysis results for each OpenFlow instance
involved in the service flow. Faulty instances are highlighted in red. Root cause analysis results
include:
− Type—Type of the root cause analysis.
− Analysis Process—Action that is taken to analyze the root cause.
− Analysis Result—Result of the action.
