Display Port Statistics
Figure 40 - Port Statistics Screen
The Port Statistics screen gives the ability to monitor port status and see how each port is
transferring data. Next to each port is a drop-down box that can also give the added ability to
monitor specific DLCI’s on a port, or all DLCI’s of a port. The ability to monitor a specific DLCI
gives “drill-down” diagnostics of the health of a circuit.
Below is a description of the fields on this screen:
Rx Bytes - The total number of bytes received since the unit was started, or since the last time
the counters were cleared.
Tx Bytes - The total number of bytes transmitted since the unit was started, or since the last
time the counters were cleared.
Rx Frames - The total number of frames received since the unit was started, or since the last
time the counters were cleared.
Tx Frames - The total number of frames transmitted since the unit was started, or since the last
time the counters were cleared.
Rx / Tx Errors - The total number of frames with illegal DLCI’s or bad LMI (Link Management
Information) frames received.
Rx /Tx Dropped - The total number of frames dropped because the DLCI is down or
unmapped, the port is down, or there is a lack of memory.
Link Status - Displays the status of the link. There are three possible values:
UP - Indicates that the link is operational.
DOWN - Indicates that the link is not operational.
NEVER UP - Indicates that the link has never been operational since the last power up or
reboot.
