VerifyCTohnefigPurrinateiornCPornonceecdtuiorne For printing on TCP/IP-attached printers, IBM recommends that you specify a shorter interval than the default, such as 10 minutes, for the interval between keep-alive transmissions. Also, if any target host requires that the keep-alive packet contain data, specify SENDGARBAGE TRUE. For example: KEEPALIVEOPTIONS INTERVAL 5 SENDGARBAGE TRUE ENDKEEPALIVEOPTIONS GATEWAY The Packet Size parameter of the GATEWAY statement defines the maximum transmission unit (MTU) for the MVS host. For IBM 10/100Base-T Ethernet Interface printers, the MTU size is fixed at 1024 bytes. The value cannot be adjusted. Verify the Printer Connection To verify that the MVS system can establish a connection with the TCP/IP-attached printer, "ping" the printer from the MVS system. From a TSO session, enter the following command: TSO PING ip_address In JES2, enter the following command from the System Display and Search Facility (SDSF) menu 6: ping ip_address ip_address specifies the IP address of the NIC. Here is an example of a successful "ping" command: EZA0458I Ping V3R1: Pinging host 9.99.12.33 (Use ATTN to interrupt.) EZA0463I PING: Ping #1 response took 0.084 seconds. Successes so far = 1. Here is an example of an unsuccessful "ping" command: EZA0458I Ping V3R1: Pinging host 9.99.12.33 (Use ATTN to interrupt.) EZA0464I PING: Ping #1 timed out NOTE: If you have problems "ping"-ing a printer, refer to "Handling MVS Connectivity Problems" on page 240. 231
