Obtaining IP Reassembly Statistics
Data packets too large to be transmitted are broken down into fragments and then
reassembled once they arrive at their destination. Obtain IP reassembly statistics if you
want to examine the reassembling and fragmenting activities an SSR is performing on IP
packets. To display such information:
1.
If you are not currently in the Front Panel view, switch to it by clicking the CoreWatch
main window.
2.
Select the Monitor menu, choose Performance, choose IP, and then choose
Reassembly Statistics.
An IP Reassembly Statistics graph similar to the following appears. By examining the
graph, you can determine how well the SSR is reassembling and fragmenting
information and when the reassembly or fragmenting activities occurred.

IP packets the SSR received, including those that have errors.
Packets that various IP protocols (including ICMP) supplied
to IP for the SSR to send out. The statistic for these packets
does not include any packets the SSR forwards.
Incoming IP packets that the SSR received and then
forwarded because the SSR was not their final destination.
Incoming IP packets the SSR successfully delivered to IP
user-protocols (including ICMP).
