Node Stats page (MoCA Network Statistics)
The Node Stats page provides an independent set of statistics for each node in the network, including
the unit itself. Each node has its own tab, on which the Tx column represents the link from the unit to the
respective node and the Rx column represents the link to the unit from the respective node. The first tab
always represents the unit itself, with other tabs representing other nodes on the network. Note the
following:
Link Control
Probe
Admission
Details on the count of frames received by and transmitted from the unit, according to
frame type:
• Tx - Frames transmitted from the unit, to any other node.
• Tx Err - Frames transmitted that did not reach the destination and/or contained
errors that could not be corrected by Reed-Solomon algorithms. These errors may
indicate a problem with the physical cable that caused frame corruption or possibly a
problem with the destination node(s).
• Rx - Frames received by the unit, from any other node.
• Rx Err - Frames received that contained uncorrectable errors. These errors
normally indicate frame corruption that occurred during the transit over the coaxial
cable.
• Drop - Received frames that could not be processed due to insufficient buffer space
(that is, too much traffic for the unit to handle) and/or frames that were expected to
be received based on NC scheduling, but never arrived.
Note the following:
• For more information on how Link Control, Probe, and Admission frames operate
on the network, see MoCA functional overview on page 7-35.
• The mechanisms by which a MoCA network manages traffic as related to these
frame counts is complex and beyond the scope of this document. See the respective
MoCA specification for more details.
Ethernet
statistics
Statistics on the Ethernet frames received and transmitted by the unit carrying user
data, such as IP video packets, as follows:
• Packets - Number of frames sent to and received from any other node on the
network
• Dropped - Frames dropped due to insufficient buffer space
These measurements are taken at the Ethernet switch “behind” the MoCA interface, as
frames transit from MoCA to standard Ethernet for internal processing. Note that these
statistics are stored in 16-bit registers and therefore may roll over periodically.
