Displaying Connection Totals

To display a summary of TCP and UDP counts, press F10 on the Work with TCP/IP Connection Status display. The counts provided are a cumulative summary of all TCP and UDP activity since the last time the STRTCP (Start TCP) command was issued.

The information in Figure 44 on page 50 and Figure 45 on page 50 shows TCP and UDP counts that are maintained for Simple Network Management Protocol
