Interpreting Data in the GPS Status Page
(AP)
pmp-0049 (September 2012)
4-35
Attribute
Meaning
PktToss Unsupported
MsgType Count
This field represents the number of packets tossed due to the receipt of
an unsupported message type (cannot be interpreted by DHCP client)
PktToss XID Mismatch
Count
The field represents the number of packets that were tossed due to a
transaction ID mismatch
PktToss NoSID Count
This field represents the number of packets that were tossed due to lack
of a DHCP session ID
PktToss SIT Mismatch
Count
This field represents the number of packets that were tossed due to a
session ID mismatch
Failure to Reset Client
Count
This field represents the number of times the DHCP client was unable
to be reset (resulting in no IP address being served).
Interpreting Data in the GPS Status Page (AP)
The GPS Status tab is only displayed when the Sync Input is set to Sync to Received Signal (Timing
Port), which is the configuration desired when connecting an AP to a CMM or UGPS.
The page displays information similar to that available on the web pages of a CMM, including Pulse
Status, GPS Time and Date, Satellites Tracked, Available Satellites, Height, Latitude, and Longitude.
This page also displays the state of the antenna in the Antenna Connection field as
Unknown—Shown for early CMM2s.
OK—Shown for later CMM2s where no problem is detected in the signal.
Overcurrent—Indicates a coax cable or connector problem, or a problem with the unit
Undercurrent—Indicates a coax cable or connector problem, or a problem with the unit
This information may be helpful in a decision of whether to climb a tower to diagnose a perceived
antenna problem.
