EZZ8164I

Explanation
 OMPROUTE has been informed by the TCP/IP stack
that the specified interface is  defined to the stack.  The subnet
mask value defined to the stack for the  interface is not the same
subnet mask value that is being used by OMPROUTE for  the interface. 
 In
the message text: stack_name
The name of the TCP/IP stack.
stack_val 
The subnet mask value that is defined to the stack for the interface.
interface
The name of the interface.
omproute_procname
The name of the OMPROUTE instance.
omproute_val
The subnet mask value that is being used by OMPROUTE for the interface.

System action
 OMPROUTE continues.  The direct route that is
added to the stack route table by  OMPROUTE, which is for the subnet
that is directly accessible over the interface, will use the subnet
mask value that is being used by OMPROUTE.   If the interface is configured
to OMPROUTE as an OSPF interface, OMPROUTE might incorrectly process
the interface  as if it is on the same LAN as another OSPF interface,
when they are not  actually on the same LAN.  The result of this incorrect
processing is that OMPROUTE puts one of the  interfaces in backup
state and will not communicate the OSPF protocol over  it.

Operator response
 Contact the system programmer.

System programmer response
 Take one of the following actions
so that the stack and OMPROUTE will use the same subnet mask value
for the interface:  If OMPROUTE is using the correct subnet mask value for the interface:
 Use the VARY TCPIP,,STOP command to stop the interface. 
Issue the VARY TCPIP,,OBEYFILE command with a profile that contains
an INTERFACE  DELETE statement for the interface, followed by an INTERFACE
DEFINE statement  for the interface that includes the correct subnet
mask value. 
Use the VARY TCPIP,,START command to start the interface.
(Optional) To make the change to the subnet mask value permanent
in the TCP/IP profile, modify the  INTERFACE statement that defines
the interface in the TCP/IP profile to specify the value that is being
used by OMPROUTE.  
To make the change in the subnet mask value permanent in
the TCP/IP profile, modify the INTERFACE statement that defines the
interface in the TCP/IP profile to specify the value being used by
OMPROUTE.  See IPAQENET OSA-Express QDIO  interfaces in z/OS Communications Server: IP Configuration
Reference for information about the INTERFACE  statement
in the TCP/IP profile.
 See VARY TCPIP,,START
or VARY TCPIP,,STOP in z/OS Communications Server: IP System Administrator's
Commands for information about the VARY TCPIP,,STOP
and VARY TCPIP,,START commands.  See VARY TCPIP,,OBEYFILE in z/OS Communications Server: IP System Administrator's
Commands for information about the VARY  TCPIP,,OBEYFILE
command.

If the stack is using the correct subnet mask value for the interface:  Modify any OSPF_INTERFACE, RIP_INTERFACE, and INTERFACE statements
 that define the interface in the OMPROUTE configuration file to specify
the  value being used by the stack.
 If the interface is configured to OMPROUTE using a wildcard configuration
statement, you might need to explicitly configure this interface with
a separate configuration statement.
If this interface is not configured to OMPROUTE and you do not
want to add it  to the OMPROUTE configuration, modify the OMPROUTE
configuration file to include a GLOBAL_OPTIONS statement that specifies
 IGNORE_UNDEFINED_INTERFACES=YES.  See OMPROUTE
configuration file in z/OS Communications Server: IP Configuration
Reference for information about the OSPF_INTERFACE,
 RIP_INTERFACE, INTERFACE, and GLOBAL_OPTIONS statements in the OMPROUTE
 configuration file.
After you have made the appropriate changes to the OMPROUTE configuration
file, restart OMPROUTE.

Automation
 This message is displayed on the system console.
 You can use automation to issue an alert when the stack and OMPROUTE
are using different subnet mask values for  an interface.

Example
  EZZ8164I TCPCS1 subnet mask value 255.255.255.0 for OSA1 differs from OMPROUT1 
         subnet mask value 255.255.0.0
