IST924I - This message is a line separator between message IST2133I subgroups.
IST1680I - The first occurrence of this message identifies the local IP address
used for the Enterprise Extender (EE) connectivity test. The second
occurrence identifies the remote IP address used for the EE connectivity
test.
- In the message text:
- type
- Indicates which IP address is being displayed. The type value
is either LOCAL or REMOTE.
- ip_address
- The IP address.
IST2119I - In the message text:
- correlator
- A unique display correlator associated with this DISPLAY EEDIAG
command. This correlator can be used to locate the various message
groups associated with this DISPLAY EEDIAG command.

IST2133I - This is the first message of a message subgroup. The message subgroup
is displayed for each TCP/IP interface that has a valid path to the
remote IP address. When LIST=DETAIL is specified, message IST2137I
(IPv4) or IST2138I (IPv6) is repeated for each time-to-live (TTL)
hop for which an LDLC probe command was sent. When LIST=SUMMARY
is specified or is the default value on the DISPLAY EEDIAG command,
message IST2137I or IST2138I is displayed only once with the information
related to the last hop that sent a reply to the LDLC probe command.
- In the message text:
- intfname
- The name of the TCP/IP interface that was used to perform the
EE connectivity test.
- intftype
- The device type that was configured on the TCP/IP profile DEVICE
statement or that was generated based on the INTERFACE statement.

IST2134I - This message indicates that the EE connectivity test to the partner
EE endpoint was successful for this specific EE port and TCP/IP interface.
- In the message text:
- portnum
- The Enterprise Extender User Datagram Protocol (UDP) port that
was tested. The default EE port numbers are as follows:
- 12000 - Signal Priority
- 12001 - Network Priority
- 12002 - High Priority
- 12003 - Medium Priority
- 12004 - Low Priority
IST2135I - This message indicates that the EE connectivity test to the partner
EE endpoint was unsuccessful for this specific EE port and TCP/IP
interface. This message might be issued if the test was unable to
contact the partner EE node, or if a TTL hop in the route returned
an unexpected Internet Control Message Protocol (ICMP) message in
response to the LDLC probe command.
- In the message text:
- sense
- The SNA sense code that was sent in the LDLC probe response from
the Enterprise Extender partner. The sense might display as ***NA*** if
a response to the LDLC probe is not received from the EE partner.
If a SNA sense code is displayed, see SNA
sense codes in z/OS Communications Server: IP and SNA Codes for more information about this sense code.
- portnum
- The Enterprise Extender User Datagram Protocol (UDP) port that
was tested. The default EE port numbers are as follows:
- 12000 - Signal Priority
- 12001 - Network Priority
- 12002 - High Priority
- 12003 - Medium Priority
- 12004 - Low Priority
IST2136I - This is an optional message in the IST2133I message subgroup
that is issued when the EE connectivity test is unsuccessful. This
message indicates that the EE connectivity test exceeded the amount
of time allowed for the test to run. This time limit is specified
or is the default value on the MAXTIME operand on the D NET,EEDIAG,TEST=YES
command.
IST2137I - This message displays information gathered during the EE connectivity
test over an IPv4 route.
- When LIST=SUMMARY is specified or is the default value on the
DISPLAY EEDIAG command, this message is displayed only once with the
information related to a reply to the LDLC probe command.
- When LIST=DETAIL is specified on the DISPLAY EEDIAG command,
this message is displayed for each TTL hop in the route to the EE
partner. To reduce repetitive information in the detailed display,
when a TTL hop is unresponsive to the LDLC probe, message IST2137I
is displayed only for the first unresponsive hop and the last unresponsive
hop. In these cases, all hops in between were also unresponsive
to the LDLC probe command.
- In the message text:
- hop
- The TTL hop count used in the LDLC probe command. The TTL hop
count is *NA (not applicable) when LIST=SUMMARY is specified.
- ipv4addr
- The source IPv4 address from the ICMP response. The source IPv4
address might display as an asterisk (*) if the TTL hop did not
respond to the LDLC probes.
- flags
- This is an optional field. The flags field
has one of two forms:
- t-ccc
- The t value is a representative character of the error
detected in response to the LDLC probe and the ccc value is
the specific code associated with an ICMP message type (if the error
detected is not associated with an ICMP message then the code value
will be 0).
The error message type is displayed as one of the
following:
- D - Destination unreachable ICMP type 3
- P - Parameter problem ICMP type 12
- Q - Source quench ICMP type 4
- H - Hop limit was exceeded. A maximum of 255 hops can be tested
when performing the EE connectivity test. The EE connectivity test
will terminate for the route being tested.
- L - A route loop condition was detected. This specific hop was
already found as a previous hop for this route being tested. Because
a route loop condition was detected the EE connectivity test will
terminate for the route being tested.
For a list of the ICMP types and codes, go to .
- (a)
- The a value is the number of LDLC probe attempts, if more
than one.
- time
- One of the following:
- The round-trip time required for the LDLC probe to be sent to
an intermediate hop for which an ICMP response was received
- The round-trip time required for the LDLC probe to be sent to
the destination hop for which either an ICMP response or LDLC probe
response was received.
This field is displayed in milliseconds (ms). If the time field
displays as 0, the round-trip time was less than 1 millisecond.
Result: The
round-trip time for intermediate hops is computed when an ICMP message
is received from the intermediate hop. Even though the round-trip
time calculated to the Enterprise Extender remote partner is based
on the receipt of a UDP datagram responding to the query that was
received, intermediate hops might delay the returning of an ICMP message.
The remote Enterprise Extender partner should always respond immediately
to the query received. Therefore, in some instances the round-trip
time to the remote Enterprise Extender node might be less than the
value computed to intermediate hops.
IST2138I - This message displays information gathered during the EE connectivity
test over an IPv6 route.
- When LIST=SUMMARY is specified or is the default value on the
DISPLAY EEDIAG command, this message is displayed only once. The information
displayed is related to the reply from the last hop that received
the LDLC probe command.
- When LIST=DETAIL is specified on the DISPLAY EEDIAG command,
this message is displayed for each TTL hop in the route to the EE
partner. To reduce repetitive information in the detailed display,
when a TTL hop is unresponsive to the LDLC probe, message IST2138I
is displayed only for the first unresponsive hop and the last unresponsive
hop. In these cases, all hops in between were also unresponsive
to the LDLC probe command.
- In the message text:
- hop
- The TTL hop count used in the LDLC probe command. The TTL hop
count is *NA when LIST=SUMMARY is specified.
- ipv6addr
- The source IPv6 address from the ICMPv6 response. The source
IPv6 address might display as an asterisk (*) if the TTL hop did
not respond to the LDLC probes.
- flags
- This is an optional field. The flags field
has one of two forms:
- t-ccc
- The t value is a representative character of the ICMPv6
message type returned in response to the LDLC probe and the ccc value
is the specific code associated with the ICMPv6 message type.
The
ICMP message type is displayed as one of the following:
- B - Packet too big ICMPv6 Type 2
- D - Destination unreachable ICMPv6 Type 1
- P - Parameter problem ICMPv6 Type 4
For a list of the ICMPv6 types and codes, go to .
- (a)
- The a value is the number of LDLC probe attempts, if more
than one.
- time
- One of the following:
- The round-trip time required for the LDLC probe to be sent to
an intermediate hop for which an ICMPv6 response was received
- The round-trip time required for the LDLC probe to be sent to
the destination hop for which either an ICMPv6 response or LDLC probe
response was received.
This field is displayed in milliseconds (ms). If the time field
displays as 0, the round-trip time was less than 1 millisecond.
Result: The
round-trip time for intermediate hops is computed when an ICMP message
is received from the intermediate hop. Even though the round-trip
time calculated to the Enterprise Extender remote partner is based
on the receipt of a UDP datagram responding to the query that was
received, intermediate hops might delay the returning of an ICMP message.
The remote Enterprise Extender partner should always respond immediately
to the query received. Therefore, in some instances the round-trip
time to the remote Enterprise Extender node might be less than the
value computed to intermediate hops.
IST2139I - In the message text:
- tested_routes
- The number of TCP/IP routes that were tested and displayed in
the EE connectivity test output.
- total_routes
- The number of valid TCP/IP routes that were found between the
EE endpoints.
IST2205I - This message is a line separator between various sections of
the message group.
IST2224I - This message is displayed when policy-based routing is being
used to determine an IPv4 route between two Enterprise Extender endpoints.
IST2225I - This message is displayed as a heading for displaying EE UDP
port numbers and their associated route tables and policy-based routing
rules.
IST2226I - In the message text:
- portnum
- The EE UDP port number.
- route_table
- The route table being used for IPv4 route calculations. If the
main routing table is being used, then the value EZBMAIN is
displayed. If the value *NONE* is displayed, then
no route could be calculated between the EE endpoints for this specific
EE UDP port and the EE connectivity test was unsuccessful.
- routing_rule
- The policy-based routing rule associated with this EE UDP port.
If no policy-based routing rule is associated with the port, then
the value NONE is displayed.
IST2227I - This message is an optional message in the IST2133I message subgroup
that is issued when the EE connectivity test is not performed because
the route is not associated with the specific EE UDP port. This message
does not indicate an error. The EE connectivity test is not performed
because the policy-based routing rule has indicated that this route
is not associated with the EE UDP port that is being tested.
- In the message text:
- portnum
- The Enterprise Extender User Datagram Protocol (UDP) port that
was tested.
