Configuration Procedure

Also, if any target host requires that the keep-alive packet contain data, specify SENDGARBAGE TRUE. For example:

KEEPALIVEOPTIONS INTERVAL 5 SENDGARBAGE TRUE ENDKEEPALIVEOPTIONSGATEWAY

The Packet Size parameter of the GATEWAY statement defines the maximum transmission unit (MTU) for the z/OS host. For 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 z/OS 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 Ethernet.

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 z/OS Connectivity Problems” on page 226.
