IST1101I

Explanation
 This message is the first of a subgroup of messages
that VTAM® issues in response
to a DISPLAY ADJCP command for an adjacent control point.
 Possible
message groups follow.  If there are active TG connections, VTAM issues
the following messages:   IST350I   DISPLAY TYPE = ADJACENT CONTROL POINT
 IST486I   STATUS= ACTIV, DESIRED STATE= ACTIV
 IST1197I  ADJCP MAJOR NODE = majornode
 IST1101I  ADJCP DISPLAY SUMMARY FOR adjcpname

If there are no active TG connections, VTAM issues the following messages:   IST350I   DISPLAY TYPE = ADJACENT CONTROL POINT
 IST486I   STATUS= ACTIV, DESIRED STATE= ACTIV
 IST1197I  ADJCP MAJOR NODE = majornode

 IST1101I  adjcpname is the name of the adjacent control
point. If the network where the resource resides is known to VTAM, adjcpname is
issued as a network-qualified name in the form netid.name.

 IST1102I  This message is a header message for the information displayed
in message IST1103I.

 IST1103I  nodename is the name of the adjacent control
point. If the network where the resource resides is known to VTAM, nodename is
issued as a network-qualified name in the form netid.name.
nodetype is the type of node and can be EN (end
node), NN (network node), or VN (virtual node). *NA* is
displayed in either of the following situations:  The device is connected and is a LEN node.
The node type has not been predefined for the adjacent CP. The
correct node type will be displayed when a connection to the node
is made.

connections is the number of active connections
to the node.
cp_connections is the number of active connections
that show support for CP-to-CP sessions.
native indicates whether nodename is
in the same APPN topology subnetwork as the node issuing the DISPLAY
command. Possible values are :  YES
If nodetype is NN and nodename shares
APPN topology information with the node issuing the DISPLAY command.
NO
If nodetype is NN and nodename does
not share APPN topology information with the node issuing the DISPLAY
command.
*NA*
If nodetype is EN or VN.

 See the z/OS Communications Server: SNA Network Implementation
Guide for more information on APPN connections and nodetypes.

 IST1104I  adjcpname is the name of the adjacent control
point. If the network where the resource resides is known to VTAM, adjcpname is
issued as a network-qualified name in the form netid.name.

 IST1105I  This message is a header message for the information displayed
in message IST1106I.

 IST1106I  resource is the name of the PU, CDRM, PORT,
or LINE associated with the transmission group number.
status is the connection status and can be
one of the following:  AC/N
Active, but not reported to APPN topology and routing services
AC/R
Active and reported to APPN topology and routing services
AO/N
Active with override but not reported to APPN topology and routing
services
AO/R
Active with override and reported to APPN topology and routing
services
AP/N
APPN connection pending, but not reported to APPN topology and
routing services
AQ/N
Quiesced, but not reported to APPN topology and routing services
AQ/R
Quiesced and reported to APPN topology and routing services
IN/N
Inactive, but not reported to APPN topology and routing services
IN/R
Inactive and reported to APPN topology and routing services
NEV
Never reported to APPN topology and routing services

tgn is the transmission group number.
cp-cp is a user-defined value that can be specified
on the GROUP, LINE, or PU definition statements or on the VARY ACT
command. This value indicates whether the connection is capable of
supporting CP-CP sessions.  Possible values are: YES or NO.
For additional information on the CPCP operand, see the z/OS Communications Server: SNA Resource Definition
Reference.

tg_characteristics is a 16-byte hexadecimal
string representing the transmission group characteristics for puname. ****
NA **** is displayed if puname is a low
entry networking (LEN) node. LEN PUs do not have transmission groups
associated with them.  Byte

2
Capacity. This value corresponds to the CAPACITY value coded in
the TGP definition statement. The displayed value is an internal representation
of the coded value. For more information on how the CAPACITY value
coded in the TG profile is mapped to the internal representation used
by VTAM, see the z/OS Communications Server: SNA Resource Definition
Reference.
3–7
Reserved (zero). 
8
Cost per unit time. This value corresponds to the COSTTIME value
coded in the TGP definition statement.

X'91'
PACKET
X'99'
LONG

13
Reserved (zero). 
14–16
User-defined. These values correspond to the values coded for
UPARM1, UPARM2, and UPARM3 respectively in the TGP definition statement.

 IST2157I  The searchoption value indicates which ALIASRCH
operand has been coded on the adjacent CP major node specified in
message IST1100I. Possible values are: YES
ALIAS searches entering this non-native entry border node are
permitted. This is also the default value.
NO
ALIAS searches entering this non-native entry border node are
not permitted.
*NA
This value is displayed if this node is not an entry border node
(BN).

 IST2251I  This message is a header message for the information displayed
in message IST2252I.

 IST2252I  The netid value is a NETID specified on the
AUTHNETS operand of the adjacent CP minor node that is specified in
message IST1103I. If the netid value is *NONE*,
then the AUTHNETS operand was specified without any NETID values.
IST2252I is repeated until all NETIDs are displayed.

System action
 Processing continues.

Operator response
 Save the system log for problem determination.

System programmer response
 If there are transmission group characteristics
(contained in tg_characteristics) that you do not
want, recode the resource definition statements.
