Ping is Successful Ping is Successful A successful "ping" usually indicates that the MVS system can communicate with the printer; however, you might receive a successful "ping" even though the IP address of the TCP/IPattached printer is a duplicate of another IP address. If PSF is unable to establish a network connection with the TCP/IPattached 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 IBM TCP/IP MVS Customization and Administration Guide.) 3. Enter the "ping" command again from the MVS system. NOTE: If you receive a successful response to the "ping" command, there is a duplicate IP address. Consult your TCP/IP network administrator. 241
