Handling z/OS Connectivity Problems

Ping is Successful
A successful “
ping
” usually indicates that the z/OS system can
communicate with the printer; however, you might receive a
successful “
ping
” even though the IP address of the TCP/IP-
attached printer is a duplicate of another IP address.
If PSF is unable to establish a network connection with the TCP/IP-
attached printer or if PSF output for this printer prints elsewhere,
follow these steps to determine whether the IP address of the
printer is unique:
1. Turn the printer off.
2. Wait at least 5 minutes for TCP/IP to clear the Address
Resolution Protocol (ARP) tables. (If your installation specified
a longer interval on the ARPAGE configuration statement in the
TCP/IP profile, you may need to wait longer. For information
about the ARPAGE statement, refer to the
TCP/IP z/OS
Customization and Administration Guide .)
3. Enter the “
ping
” command again from the z/OS system.
NOTE: If you receive a successful response to the “
ping
”
command, there is a duplicate IP address. Consult your
TCP/IP network administrator.
