Frames Received The number of Ethernet frames received by the LEC.
Frames Transmitted The number of Ethernet frames transmitted by the LEC.
Octets Received The number of Ethernet octets received by the LEC.
Octets Transmitted The number of Ethernet octets transmitted by the LEC.
If you see the following symptoms, there may be a problem at the ATM Switch end of the connection:
The LEC is active and the LEC Operation at Failure is None, but the frames or octets counters are showing zero.
If you have followed the troubleshooting instructions in this section and within Appendix D, and you still have a problem, contact IBM Technical Support. Refer to Appendix E for details.
The following button is available on this screen:
CLEAR SCREEN COUNTERS To make it easier to note the changes in statistic values, you can use this button to reset the value of statistics shown on the screen to zero. Resetting the values shown on the screen does not reset the statistic values stored on this device.
ATM Physical Layer Statistics
The Physical Layer Statistics screen shows SONET
To access Physical Layer statistics, first access the ATM Port Statistics screen, as described in “ATM Port Statistics” on page
An example of the Physical Layer Statistics screen is shown in Figure
Port Identifies the currently selected port.
OCD State Shows the Out of Cell Delineation (OCD) state. The OCD State is set to Fail when seven consecutive cells have had Header Error Control violations. This implies that the cell has been corrupted and that there is probably a hardware problem with the ATM Module or ATM Switch.
The OCD State is only set to OK when six good cells are received by the ATM Module followed by approximately 10 seconds of good signal from the ATM fiber optic cable.
