Chapter 2 - General Purpose Command Set Ipstat Command (IP-Statistics)
Alvarion BreezeNET B130/B300 GigE 23 Operational User Manual
If the record table in the router memory overflows, or if there is not enough
memory currently available, an appropriate warning is written into the system log,
and further statistical data are discarded. If enable "ipstat strict" option has been
specified, then at the overflow condition the transit routing is disabled, but the
router still responds to any protocol.
A more reliable method of remotely getting statistical info consists in using the
following commands:
 ipstat fixit - dumps the currently collected info from the device's memory into
an intermediate buffer. The memory is cleared, and continues receiving info
over again.
 ipstat fixget - shows the content of the dump buffer. This command may be
executed any number of times, with no damage to the dumped statistical info.
 ipstat fixclear - clears the temporary dump buffer
The listing of statistical info provides:
 time elapsed since the previous "clear" operation
 number of records effectively used, and total record space available
 number of bytes lost due to record memory overflow list of all records.
If the record table in the device memory overflows, or if there is not enough
memory currently available, an appropriate warning is written into the system log,
and further statistical data are discarded. If strict option is enabled then at the
overflow condition the transit routing is disabled but the device still responds to
any protocol.
The ipstat add [ifname] rule command makes it possible to filter packets for
statistic gathering, taking into account only those packets which satisfy the rule.
The syntax of the "rule" parameter is the same as defined in the ipfw command
description.
The ipstat del N command deletes the N-th rule from the list of rules.
The ipstat rearrange N command renumbers all the ipstat rules with the given
increment (default step is 1).
The ipstat traf [detail] [bytes | total_bytes] allows for visually inspecting
statistics collection process in real time. Detail option switch on detailed ip
