A Port Error Statistics graph similar to the following appears. By examining the graph,
you can determine how many of the different errors a port is experiencing and the time
at which those errors occurred.
Figure 177. Port Error Statistics Graph
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
“Using the Graph
Toolbar” on page 277 .

Abbreviation Description
InErrs Erroneous packets received on the port.
OutErrs Erroneous packets sent out from the port.
InDiscrd Incoming packets the SSR discarded although no errors had
been detected to prevent the SSR from delivering them to a
higher-layer protocol. Freeing buffer space is one possible
reason for discarding such packets.
OutDiscrd Outgoing packets the SSR discarded although no errors had
been detected to prevent the SSR from sending them
elsewhere. Freeing buffer space is one possible reason for
discarding such packets.
