Explanation
A DISPLAY EEDIAG,TEST=YES command was issued to
perform an Enterprise Extender connectivity test. This message
is the first message in a group of messages displayed when the test
fails because the remote IP address is not in the same IP address
family as the local IP address; for example, the local IP address
is an IPv4 address and the remote IP address is an IPv6 address.
If the addresses are in different families, the Enterprise Extender
connection cannot be established. A complete description of the message
group follows.
IST2129I CONNECTIVITY TEST FAILED - MISMATCH OF IP ADDRESS FAMILY
IST1680I type IP ADDRESS ip_address
[IST1909I REMOTE HOSTNAME value]
[IST1911I value]
IST1680I type IP ADDRESS ip_address
[IST1910I LOCAL HOSTNAME value]
[IST1911I value]
IST314I END
IST1680I - In the message text:
- type
- Identifies the IP address that is displayed. The type value
is either LOCAL or REMOTE..
- ip_address
- Either the remote IP address or the local IP address. The first
instance of the IST1680I message displays the local IP address, and
the second instance of the IST1680I message displays the remote IP
address.
IST1909I - In the message text:
- value
- The host name, owned by a target remote node, that was used to
acquire the remote IP address as part of name-to-address resolution.
If the host name is longer than 44 characters, then the first 44
characters are displayed as the value value and
the remaining characters are displayed in one or more IST1911I messages.
IST1910I - In the message text:
- value
- The host name used to acquire the local static VIPA address that
is used as part of the attempted route determination. If the host
name is longer than 45 characters, then the first 45 characters are
displayed as the value value and the remaining
characters are displayed in one or more IST1911I messages.
IST1911I - In the message text:
- value
- The continuation of the value value on message
IST1909I or IST1910I. Message IST1911I is repeated as many times
as necessary to display the entire character string.
System action
The DISPLAY EEDIAG,TEST=YES command is not performed.
Operator response
If both a local and remote IP address are
supplied as input to the D NET,EEDIAG,TEST=YES command, enter the
command again specifying both IPADDR filters from the same IP address
family. Otherwise, save the console log for problem determination.
System programmer response
The Enterprise Extender connectivity
test cannot be performed if the local and remote IP addresses are
not in the same address family. If the correct host name is being
specified on the display command, verify the following:
- The name-to-address resolution mapping for the host name yields
the expected static VIPA address (if on a z/OS® host) of the node that owns the host name.
- If network address translation (NAT) is in use, the name-to-address
resolution mapping for the host name yields the correct NAT address
to ultimately reach the target static VIPA address of the node that
owns the host name.
If the resolution is not correct, update the DNS zone
files or the appropriate local host files with the corrected name-to-address
resolution. If the resolution is intended to yield an IPv6 address,
ensure that the TCP/IP stack is enabled for IPv6 processing so that
the resolver searches for IPv6 addresses. See the information about
resolvers in z/OS Communications Server: IP Configuration
Guide for more information about the resolver
function.
