EZD1786I

Explanation
 IKEv1 does not support the negotiation of tunnels
for specific ICMP types and  codes, ICMPv6 types and codes, or MIPv6
types and codes.  The filter rule specified by the rulename value
uses an IpService definition that specifies either individual types
and codes or a range of types and codes, for ICMP, ICMPv6, or MIPv6
traffic. A tunnel negotiation was attempted that used the specified
filter rule with a KeyExchangeAction statement that requires IKEv1
to initiate the negotiation.  Tunnels that use either individual types
and codes or a range of types and codes can be negotiated for IKEv2,
but not for IKEv1.
 In the message text:  rulename
The name of the filter rule.

System action
 The tunnel activation fails; IKE daemon processing
continues.

Operator response
 None.

System programmer response
 Examine the policy definition for
the rule name and modify it to correct the error.   Potential changes
include:  Specify HowToInitiateVersion IKEv2. 
Do not code specific values or ranges of ICMP, ICMPv6, or MIPv6
types and  codes.

User response
 Not applicable.
