Calculating packet loss for routed PVCs in Example 6

To calculate packet loss for routed PVCs in Example 6, perform these tasks.

  1. Display the value for INPKTS received on the ingress ATM port, by entering this command:
    2. show port stats atmp <ingress atm port>
  2. Display the value for InUcastPkts on the ingress ATM port, by entering this command:
    3. show atm elan <elan number>
  3. Display the value for IN_FRAME_UNICAST from the ingress ATM port, by entering this command:
    4. show port stats routing <ingress atm port>
  4. Display the value for OUT_FRAME on the egress Ethernet port, by entering this command:
    5. show port stats routing <ethernet port>
  5. Calculate the difference between the IN_FRAME_UNICAST value and the OUT_FRAME value to estimate packet loss.

    Note Note: Packet loss for ingress ATM to egress Ethernet examples is lower than packet loss for ingress Ethernet to egress ATM examples.
