The following table describes the abbreviations used in the legend located at the 
bottom of the graph. You can control the graph's appearance and pause or resume the 
gathering of statistics by using the Graph toolbar as discussed in 

.

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.

Table 40. IP Packet Statistics Graph Abbreviations

InRecv

IP packets the SSR received, including those that have errors.

OutReq

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.

ForwDatgrm

Incoming IP packets that the SSR received and then 
forwarded because the SSR was not their final destination.

InDelivers

Incoming IP packets the SSR successfully delivered to IP 
user-protocols (including ICMP).
