Specs
• The unit arranges the table with the worst performing link shown at the top left, with improving
performance expanding towards the bottom right.
• The top of the screen indicates which node represents the unit (node 9 in this example). In the table
headings below, the network coordinator (NC) is indicated by an asterisk, which may or may not be
the unit.
• You can use the Display Version control to limit the table to nodes running a specific MoCA version.
• Any result shaded in red or yellow has violated a configured threshold (see Thresholds on
page 7-28).
• Gray (blank) table cells appear for the following reasons:
– When the cell would represent a link between a node and itself, which is not applicable.
– When the cell represents a link between two external nodes (neither of which are the unit) and the
network MoCA version is earlier than 1.1. Earlier versions of MoCA only support bandwidth
statistic retrieval for links involving the node from which they were queried (in this case, the unit).
– When the cell represents a link to or from a node that has been removed from the network, while
bandwidth reporting was in progress. If a node is removed, the unit does not remove the row and
column for that node; rather, it simply grays out any applicable cells.
• On the touchscreen, you can press any row or column header cell to jump to the node statistics page
for the respective node (see MoCA Statistics page (MoCA Network Statistics) on page 7-11).
• Real-world bandwidths will vary from the theoretical maximums allowed by the MoCA standards. A
lower bandwidth may indicate an issue with the physical network that is degrading performance, but
may not necessarily prove that the bandwidth reduction is causing any problems itself. As long as the
bandwidth is sufficient for the traffic that must traverse the respective link, a reduced bandwidth
should not exhibit any visible problems with the network.
Furthermore, the actual Ethernet bandwidth carried by a MoCA network is approximately 55% of the
MoCA-level bandwidth. Therefore, a MoCA network must maintain nearly 200 Mbps for a fully-
functional 100 Mbps Ethernet link.
• The bandwidth between two nodes is typically asymmetrical, with a different rate for each direction.
The difference is especially pronounced when the in/out polarity of splitters is reversed between
directions.
MoCA Statistics page (MoCA Network Statistics)
The MoCA Statistics page provides general details of the overall network. Note that unless otherwise
noted, results are cumulative since the time the unit joined the MoCA network. You can rest all counts to
zero by using the Reset command (F3).
Preliminary issue - Limited distribution only!
