MSR Lab Part 1

• Boot and Verify MSR
• Reset Switch (Hardware Reset, push reset button
  on switch)
• Use MSR_Config to boot and configure the MSR
• Check for booting kernel via serial ports (tip
  and cu)
• Use basic cmd protocol commands to check status
• User AAL5Generator to generate traffic.
• Monitor traffic using cmd protocol
• GUI Traffic Monitoring
• Start newGBNSC
• Start monitoring gui
• Use given AAL5Generator command to generate
  traffic
• Try changing options to AAL5Generator to change
  traffic load
• Change what you are monitoring
• Experiment with gui and traffic generator

6
MSR Lab Part 1 (continued)

• Rebuild the existing MSR Kernel
• MSR_SPC
• config
• make
• cp netbsd /usr/MSR
• Place symbol-only version of kernel in file
  system.
• Download and boot
• Retest with traffic generator and monitoring gui
• How many 1 cell packets can it forward?
• Build a Performance Kernel
• MSR_SPC_PERF
• config
• make
• cp netbsd /usr/MSR
• Place symbol-only version of kernel in file
  system.
• Repeat tests from above

7
MSR Lab Part 2

• Routing Tests and Tools
• Manually install routes using cmd protocol (FIPL
  or SIPL?)
• Test and monitor
• Plugins
• Pre-built plugin already in File System
• Load a plugin
• Install filter(s) and bind
• Generate test traffic and monitor
• Remove filter(s) and Plugin
• Modify Plugin and rebuild
• Change print output in the plugin
• Rebuild
• Load into File system
• Re-load MSR
• Re-test Plugin

8
MSR Lab Part 2 (Continued)

• Communicating with a Plugin
• Use cmd protocol to retrieve plugin packet count
• Modify plugin to accept other command(s)
• Use cmd protocol to send new command(s)
• Modify file system to include new plugin
• Retest
