Step 2 (B): Identify an Available UDP Port Number
for NonStop TCP/IPv6 Use
you define the Expand-over-IP line-handler process in Step 4: Create the Line-Handler
Process.
Step 2 (B): Identify an Available UDP Port
Number for NonStop TCP/IPv6 Use
A User Datagram Protocol (UDP) port number enables multiple applications to use
the same IP address. An Expand-over-IP line-handler process might share a local IP
address with other applications or with other Expand-over-IP processes. Each must
specify a different port number. To avoid conflict, identify an available UDP port number
for the IP address you selected in Step 1 (B): Select a Process and SUBNET for
NonStop TCP/IPv6 Use.
You can use the SCF STATUS MON command to determine which UDP port numbers
are already in use for a particular SUBNET. To obtain a list of available UDP port
numbers, issue this SCF command:
> STATUS MON $ZZTCP.*
Example 8-8 shows a sample result of the SCF STATUS MON command.
Note. You must also perform this step on the destination system before you can define the
local Expand-over-IP line-handler process. The destination UDP port number must be
specified when the local Expand-over-IP line-handler process is defined.
