9.2.7.2 Requesting Link Statistics From the ICP
The get statistics command requests a configuration report for a particular link. The ICP
maintains a set of statistics for each link that keeps track of events occurring on each
ICP physical port.
To request the statistics on an ICP link, the client sends a message with the optional
arguments structure shown in Figure 9–15. There is no data area for a link statistics
request.
At the ICP, the fields of the ICP and protocol headers that the ICP receives contain the
following values:
ICP_HDR
count = size of protocol header (16 bytes)
command = DLI_ICP_CMD_WRITE
status = high bits indicate byte ordering
