IST924I - This message is a line separator between subgroups.
IST1315I - This message is issued when the number of EE connections displayed
exceeds the value specified for the MAX operand.
- number is the value specified for the MAX
operand.
IST1909I - value is the host name used to acquire the
remote IP address associated with this connection to the remote node.
If the host name is longer than 44 characters, then the first 44
characters are displayed as value and the remaining
characters are displayed in one or more IST1911I messages.
IST1910I - value is the host name used to acquire the
local static VIPA address displayed in message IST1680I. If the host
name is longer than 45 characters, then the first 45 characters are
displayed as value and the remaining characters
are displayed in one or more IST1911I messages.
IST1911I - value is the continuation of value on
messages IST1909I and IST1910I. IST1911I is repeated as many times
as necessary to display the entire character string.
IST2023I - This message is issued when the ID operand is specified with
a switched PU name that has an active Enterprise Extender connection.
- linename is the name of the Enterprise Extender
line used for this Enterprise Extender connection.
IST2024I - This message is not issued in the case where the ID operand
is specified with a switched PU name that has an active Enterprise
Extender connection. In this case, message IST2023I is issued.
For all other cases, this message is issued as part of the DISPLAY
EEDIAG connection display.
- puname is the name of the switched PU used
for this Enterprise Extender connection.

IST2035I
IST2036I - This message is associated with a subgroup of messages that begins
with message IST2030I, IST2031I, IST2032I, IST2033I, IST2034I or
IST2035I.
- nlps_sent is the total number of network layer
packets (NLP) that have been sent across this EE connection for this
specific priority. This value is maintained from the time this connection
was activated, or since the last DISPLAY EEDIAG command was issued
specifying the CLEAR=ALL|REXMIT parameter.
- estimate is an estimate of the displayed nlps_sent.
It is in the form xxxU, where xxx is a numeric value
and U is the unit of measure for xxx as follows:
- K
- Estimate is in units of 1000 NLPs.
- M
- Estimate is in units of 1 000 000 NLPs.
- G
- Estimate is in units of 1 000 000 000 NLPs.
- T
- Estimate is in units of 1 000 000 000 000 NLPs.
- P
- Estimate is in units of 1 000 000 000 000 000 NLPs.
IST2038I - This message is associated with a subgroup of messages that begins
with message IST2030I, IST2031I, IST2032I, IST2033I, IST2034I or
IST2035I.
- nlps_retransmitted is the total number of network
layer packets (NLP) that have been retransmitted across this EE connection
for this specific priority. This value is maintained from the time
this connection was activated, or since the last DISPLAY EEDIAG command
was issued specifying the CLEAR=ALL|REXMIT parameter.
- estimate is an estimate of the displayed nlps_retransmitted value.
It is in the form xxxU, where xxx is a numeric value
and U is the unit of measure for xxx as follows:
- K
- Estimate is in units of 1000 NLPs.
- M
- Estimate is in units of 1 000 000 NLPs.
- G
- Estimate is in units of 1 000 000 000 NLPs.
- T
- Estimate is in units of 1 000 000 000 000 NLPs.
- P
- Estimate is in units of 1 000 000 000 000 000 NLPs.
IST2042I - count is the number of matching EE connections
displayed in the output.
- total is the total number of EE connections
that match the parameters specified on the DISPLAY EEDIAG command.
The total might be larger than the displayed count because the number
of EE connections displayed is governed by the MAX parameter.
IST2065I - This message is the header message for the Enterprise Extender
connection retransmission information display output.
IST2067I - The date and time values
specify when this DISPLAY EEDIAG command was issued. See DATE and TIME formats for information about the date and time values.
IST2068I - This message is associated with a subgroup of messages that begins
with message IST2030I, IST2031I, IST2032I, IST2033I, IST2034I, or
IST2035I.
- nlp_retransmit_rate is the current network
layer packet (NLP) retransmission rate for this EE connection.
This rate is maintained for each specific priority. Issuing the
LIST=DETAIL on the DISPLAY EEDIAG,REXMIT command displays the current
retransmission rate for each priority level. The LIST=SUMMARY output
displays the average retransmission rate for all priorities associated
with this EE connection. This value is maintained from the time
this connection was activated, or since the last DISPLAY EEDIAG
command was issued specifying the CLEAR= ALL|REXMIT parameter.
- It is in the form xxx%, where xxx is the numeric
value of the retransmission rate, specified as a percentage.
IST2069I - The date and time values
specify when the retransmission counters were last cleared for this
EE connection. The date and time values displayed in this message,
combined with the date and time values displayed in message IST2067I,
provide the time interval during which the retransmission metrics
were collected. See DATE and TIME formats for
information about the date and time values.
IST2071I - count is the number of EE connections that
had both their REXMIT and SRQRETRY counters cleared as a result of
the CLEAR=ALL parameter.
IST2072I - count is the number of EE connections that
had their retransmission counters cleared as a result of the CLEAR=REXMIT
parameter.
IST2073I - count is the number of EE connections that
had their SRQRETRY counters cleared as a result of the CLEAR=SRQRETRY
parameter.
IST2119I - This is an optional message that is issued when the DISPLAY EEDIAG
command contains HOSTNAME filters.
- The correlator value is a unique display correlator
associated with this DISPLAY EEDIAG command, which requires host name
resolution. This correlator can be used to locate the various message
groups associated with this DISPLAY EEDIAG command.
System action
Operator response
If the nlp_retransmit_rate value
displayed in message IST2068I is unusually high, the Enterprise
Extender network might need to be diagnosed to determine why the packets
are being discarded or lost. If the nlp_retransmit_rate value
displayed in message IST2068I is unacceptable, and an alternate
non-EE path to the partner exists, the EE connection might need
to be deactivated so RTP pipes can pathswitch to the non-EE path.
