EZD1770I

Explanation
 The Internet Key Exchange (IKE) daemon was unable
to accept a proposal because the local and remote  IKEv2 Security
Association (SA) transform attribute values are not the same.   IKE
daemon processing continues to the next proposal. If no proposals
are  accepted, the SA negotiation fails. This failure is indicated
by message EZD0985I, EZD1021I, or EZD1022I  being issued later in
syslog.
 In the message text:  transform_name 
The name of the transform for which the mismatch occurred.
local_attribute_type  and remote_attribute_type 
The attribute types.
local_proposal_number  and remote_proposal_number 
The proposal numbers.

 The attribute values are not included in
the message because they are variable length and might be as large
as 64 kilobytes of data.  To obtain the remote proposal value, activate
the formatting of IKE messages by using IKE syslog level 8 and attempt
the SA negotiation.

System action
 IKE daemon processing continues.

Operator response
 Contact the system programmer.

System programmer response
 If the proposal that contains the
mismatch is the one that should be accepted,  either alter the local
policy to accept the value in this proposal or notify  the administrator
of the remote security endpoint about the mismatch and ask  the administrator
to alter the remote configuration to use the correct values.  See
the information about Policy Agent and policy applications in z/OS Communications Server: IP Configuration
Reference for more information  about configuring policy
and the  IkeSyslogLevel statement. 

User response
 None.

Problem determination
