EZD1223I
MLSCHK LOCAL ZONE HAS INCORRECT SECLABEL zonesl IPADR ipaddress IF ifcname ZONE zonename zoneentry RESNM resourcename PRFNM profilename

Explanation

In a multilevel secure environment, an interface is configured into a NETACCESS security zone with an incorrect security label for the TCPIP job that owns the interface. See message EZD1215I for the security label of the TCPIP job. Local interface addresses must be in zones with the same security label as the TCPIP job. VIPAs on an unrestricted stack may be in a security zone with any security label that is currently active on that system. VIPAs on a restricted stack must be in zones with a security label that is not SYSMULTI and is equivalent to the TCPIP job.

zonesl is the security label defined in the SECLABEL field in this SERVAUTH profile. If the SECLABEL field is blank, zonesl will be <NONE>.

ipaddress is the IPv4 or IPv6 address on the local interface.

ifcname is the name of the INTERFACE or IPv4 LINK statement that defined this IP address.

zonename is the security zone name defined in the NETACCESS zone entry for this IP address.

zoneentry is the NETACCESS zone entry for this IP address. zoneentry will one of the following:
  • DEFAULT
  • DEFAULTHOME
  • ipaddress/masklength

resourcename is the name of the SERVAUTH resource.

profilename is the name of the SERVAUTH profile that covers this resource name.

System action

TCPIP continues.

Operator response

Contact the system programmer.

System programmer response

Verify that:
  • The IP address is intended to be owned by this TCPIP JOB.
  • The NETACCESS statement maps the IP address into the correct security zone.
  • The resource name is covered by the intended profile in the SERVAUTH class.
  • The profile has the correct security label defined.
  • The security label is defined and active on this system.

See z/OS Communications Server: IP Diagnosis Guide for more information about diagnosing TCPIP access control problems.
