Monitoring at a 0.3 sec interval:

• RLI: Port 2.6 => Egress => Port Bandwidth
  An Add Parameter dialog box appears.
• Add Parameter: Enter 0.3 seconds (select the 1 sec default if you wish).
  A monitoring window appears with the label OPPBW-2.
• Select the OPPBW-2 label.
  A label dialog box appears.
• Enter top to right as the new label.
• Repeat for the other three monitoring points
  • Port 1.6 => Egress => Port Bandwidth
    Label: bottom to left
  • Port 1.7 => Egress => Port Bandwidth
    Label: top to left
  • Port 2.7 => Egress => Port Bandwidth
    Label: bottom to right

Sending ping packets (default size and period):

• Enter: source /users/onl/.topology
  Define ONL environment variables. Use /users/onl/.topology.csh if your shell is a C-shell instead of the bash shell.
• ssh to $n2p2 from the ONL login host (note that $n2p2 is the external interface name)
• Enter: ping n1p2
  You should see the default ping output of one line every second showing how many bytes were sent and the round-trip time.
