IST2387I

Explanation
 This message is the first in a group of messages
that VTAM® issues when a dial
fails for an Enterprise Extender (EE) connection across a connection
network. The complete description of the message group follows:     IST2387I DIAL FAILED - DUPLICATE IP ADDRESSES ON EXISTING CONNECTION
     IST2388I EE VRN = vrn_name
     IST1680I type IP ADDRESS ip_address
     IST1680I type IP ADDRESS ip_address
     IST314I END

IST1680I
This message
displays the IP addresses of the failing connection. In the message
text: type
Indicates which IP address is being displayed. The value is either
LOCAL or REMOTE.
ip_address
The IP address.

IST2387I
This message is issued
when a dial request for an EE connection across a connection network
fails. An existing connection network was found with the same local
and remote IP addresses. For a connection network, the IP address
applies to one of the following conditions:Specified on the IPADDR operand on the EE XCA GROUP statement
that defines the connection network (VNNAME)
Inherited from the IPADDR start option
Resolved from the HOSTNAME value specified on the EE XCA GROUP
statement that defines the connection network

IST2388I
This message displays the name of
the virtual routing node (VRN) of the existing EE connection network
that has the same local and remote IP addresses. In the message text: vrn_name
The name of the VRN of the existing EE connection network found
with the duplicate IP addresses.

System action
 The EE dial request fails, but the existing EE
connection is unaffected.

Operator response
 Contact the system programmer.

System programmer response
 Correct the EE XCA major node GROUP
definitions so that multiple connection networks do not have the same
local and remote IP addresses between two EE hosts. If you are using
the TCP/IP resolver to perform name-to-address resolution, ensure
that the HOSTNAME value on the GROUP definition for each connection
network resolves to a unique IP address. See Configuring
the EE connection network in z/OS Communications Server: SNA Network Implementation
Guide for more information about defining multiple
EE connection networks between two adjacent CPs. See z/OS Communications Server: IP Configuration
Guide for more information about defining name
servers to the resolver.
