UMAC Statistics
The UMAC functions occur in the unit’s processor. The UMAC statistics are
likely the most useful for radio troubleshooting. This window breaks down the
statistics into clean and failed packets.
The failed packets should be less than 10% in a normal operating environment. In
the TX statistics, there should be little to no Retransmits at Series 2, 3 or 4. Life
Statistics are reset on each reboot.
Ethernet Statistics
In this window, excessive collisions are usually a sign that the radio and the device
it is linked to are not on the same duplex settings. One is at full while the other is
at half. Try locking both to the same values.
Collisions do normally occur on an Ethernet network and are generally handled by
the Carrier Sense Multiple Access with Collision Detect (CSMA/CD) mechanism.
Alignment, length and excessive FCS errors could the result of a bad radio link, or
a bad Ethernet cable.
