IT35910: ANS1017E / ANR0443W INVALID "MACADDRESS" IF THE IPV6 ADDRESS EXCEEDS 30 CHARACTERS

APAR status

• Closed as program error.

Error description

• When using IBM Spectrum Protect client version 8.1.11, clients
  fail to connect to the server when using COMMMETHOD V6TCPIP if
  the IPv6 address is longer than 30 characters.
  
  The following error happens at client side (as seen in the
  dsmerror,log):
  
  
   ANS0361I DIAG: ..\..\common\cu\cucommon.cpp(2216):
    cuSignOnEResp(): Error -50 receiving SignOnEResp
   ANS1017E Session rejected: TCP/IP connection failure.
  
  The server shows the following protocol errors in his actlog:
  
   ANR0443W Protocol error on session xx for node yy (WinNT) -
    invalid "MacAddress" field found in "SignOnEnhanced2" verb
    (offset 75).
  
   ANR0421W Session xx for node yy (WinNT) refused - sign-on
    protocol violation.
  
  Customer/Support Diagnostics:
   On Windows platforms, the command "ipconfig /All" will show
      the "IPv6 Address" .
   On Unix, it is command "ifconfig -a" , which lists
      the "inet6" address.
  
  IBM Spectrum Protect Versions Affected:
    Client V8.1.11 on all supported platforms
     | MDVREGR 8.1.11.0-TIV_5698MCL |
  
  Initial Impact: Medium
  
  Additional Keywords: TSM TS004688992 character chars
  

Local fix

• Rollback to client level 8.1.10 until a solution for COMMMETHOD
   V6TCPIP is available.
    - or -
  
  Switch to COMMMETHOD TCPIP if possible.
