Calculating packet loss in Example 4

To calculate packet loss for Example 4, perform these tasks.

  1. Display the value for IN_FRAME_UNICAST for each Ethernet port in the bridged VLAN, by entering this command:
    2. show port statistics bridged <ethernet port>
  2. Calculate the total of the IN_FRAME_UNICAST values.
  3. Display the value for OUT_FRAME for the ATM port to which the bridged PVC belongs, by entering this command:
    4. show port statistics bridged <atm port>
  4. Calculate the difference between the IN_FRAME_UNICAST total value and the OUT_FRAME value to estimate packet loss.
  5. Display the value for OutUcastPkts for the ATM port, by entering this command:
    6. show atm elan <elan number>
  6. Display the value for OUTPKTS for the ATM port, by entering this command:
    7. show port stats atmport <atm port>
  7. Calculate the difference between the OUT_FRAME value and the OutUcastPkts value. The result should be near or equal to the value displayed for OutDiscards when you enter this command
    8. show atm elan <elan number> output
