EZZ0726I

Explanation
 A reserved IPv6 address cannot be specified on
the IP configuration statement  at line lineno. 
 A reserved
IPv6 address is one of the following:  Universal/local bit is set (bit 71). 
Individual/group bit is set (bit 72). 
The first four bytes of the interface ID are X'00005EFE'. 
The first 57 bits of interface ID, except universal/local and
individual/group  bits, are set to 1 (for example, FCFFFFFFFFFFFF8/57).

See the z/OS Communications Server: IPv6 Network and
Application Design Guide for information about IPv6 addresses.   

System action
 If processing an initial profile or
a VARY TCPIP,,OBEYFILE command, TCP/IP ignores the statement. TCP/IP
continues. 
This message is also displayed as part
of VARY TCPIP,,SYNTAXCHECK processing when the VARY TCPIP,,SYNTAXCHECK
command detects this error in a profile data set.  No changes are
applied to the active configuration by VARY TCPIP,,SYNTAXCHECK processing.

Operator response
 Contact the system programmer.

System programmer response
Correct the statement.
If this message was displayed as a result of a VARY TCPIP,,SYNTAXCHECK
command, issue the command again to verify that you have corrected
all syntax errors in the profile. Otherwise, use the VARY TCPIP,,OBEYFILE
command to rerun the configuration statement. 

Module
 EZACFPV6

Automation
This message is directed to the console.
You can use automation to detect and respond to TCP/IP profile errors
reported during initial profile and VARY TCPIP,,OBEYFILE processing.
This
message can also be displayed during VARY TCPIP,,SYNTAXCHECK processing.
Because the VARY TCPIP,,SYNTAXCHECK command does not affect the active
configuration, you might want to adjust your automation to ignore
the configuration messages that are displayed after EZZ0061I and before
EZZ0065I.
