Description
Counter showing the number of slots that have been advertised on this
upstream port for bandwidth request opportunities since the router last
reset or the counters were last cleared.
Counter showing the number of slots that have been advertised on this
upstream port for request/data transmission opportunities since the
router last reset or the counters were last cleared.
Number of slots that have been granted on this upstream port for initial
maintenance requests (initial ranging) since the router last reset or the
counters were last cleared.
Number of slots that have been granted on this upstream port for station
maintenance requests (unicast ranging) since the router last reset or the
counters were last cleared.
Number of slots that have been granted on this upstream port for short
data requests since the router last reset or the counters were last cleared.
Number of slots that have been granted on this upstream port for long
data requests since the router last reset or the counters were last cleared.
Number of frames received by this upstream port that have been
fragmented according to the DOCSIS 1.1 fragmentation technique.
Displays fragmentation statistics. If fragmentation is disabled, no
statistics are available. If fragmentation is enabled, the fragmentation
mode is displayed (multiple grant mode or piggyback mode), and the
display shows the fragmentation threshold in the number of bytes and
minislots.
Total upstream bandwidth that is currently being used for upstream data
traffic and DOCSIS management traffic, expressed as a short-term
average percentage of total minislots being used.
See
Table 3-53 on page 3-218
Note
possible bandwidth for an upstream, based on the channel width
and modulation scheme.
the total upstream bandwidth that is currently dedicated to providing
bandwidth request opportunities, expressed as an average percentage of
total minislots being used. This value is calculated by dividing the
number of scheduled contention slots by the total number of minislots.
Note
This value is approximately 100 percent minus the percentage of
slots being used for upstream data, management traffic, and
initial ranging slots.
Total upstream bandwidth that is currently being used, on average, for
initial ranging requests for cable modems coming online, expressed as
an average percentage of total minislots being used.
