Interpretation of the relevant parameters:
CDR:
This parameter is only valid under proxy mode;
Robustness:
Robustness parameters:
Snooping Aging Time:
The aging time under snooping mode will be reset when report packet is received.
Proxy Member Aging Time:
The aging time of the proxy model, is calculated [General Query Interval] * [Robustness] + [Query
Max Resp Time], resets the received packet report time;
The
aging
time
under
proxy
mode
will
be
reset
when
report
packet
is
received,
the
calculation formula
is: [General Query Interval] * [Robustness] + [Query Max Resp
Time]
Query Max Resp Time:
Query packet maximum response time, the value is sent to ONU by inserting into the query package,
if there is multicast group table entry in ONU, one report message should be responded in random
in [1, Query, Max, Time], the unit is 0.1s.
General Query Interval:
General query interval, in proxy mode, OLT sends query packets to all dynamic members in every
[General, Query, Interval] seconds to maintain multicast group table entry.
Startup Query Interval:
