Purpose

The DISPLAY TOPO (topology) command displays information about the topology of an APPN network.

This command is valid in all APPN-capable hosts. However, because end nodes and migration data hosts do not receive topology updates (TDU) from other nodes, only local topology resources and brief information about adjacent nodes can be displayed at end nodes. For example, you can display detailed information about the local end node and the TGs originated at that end nodes. The end node's topology database does not have information about any TGs originated at an adjacent node to the end node itself. End nodes know the following information about an adjacent node:
  • Network-qualified CP name
  • Node type (network node, end node or virtual node)
  • Status of the CP-CP sessions between the local end node and the adjacent node
This command displays only the information that is found in the topology database. Some resources might not be displayed in a network node or an interchange node for the following reasons:
  • No CP-CP session path exists between the resource and the node from which this command is issued.
  • Information about end nodes and the resources they own is not broadcast to the network.
  • Information between two nonnative nodes is limited to keep them from being used as intermediate nodes.

When you display transmission group (TG) information, the order in which you specify the origin and destination can make a difference. ORIG=A,DEST=B does not necessarily display the same results as ORIG=B,DEST=A.

The following examples illustrate how this command works.

Figure 1. DISPLAY TOPO topology example 1
DISPLAY TOPO topology example 1
In Figure 1, end node A (ENA) has a CP-CP session with network node 1 (NN1) and an active link to network node 2 (NN2). Also, a CP-CP session exists between NN1 and NN2. The command:
D NET,TOPO,ORIG=NN2,DEST=ENA
issued from NN2 displays the requested TG information. However, the command:
D NET,TOPO,ORIG=ENA,DEST=NN2

issued from NN2 causes an error message, RESOURCE NOT FOUND. Because ENA is an end node, its TGs are not broadcast to the network, so NN2 does not know that ENA has a TG from ENA to NN2.

Figure 2. DISPLAY TOPO topology example 2
DISPLAY TOPO topology example 2
In Figure 2, CP-CP sessions exist between NN1 and NN2 and between NN2 and NN3. Suppose the link between NN2 and NN3 goes down. The command:
D NET,TOPO,ORIG=NN2,DEST=NN3
issued from NN1 indicates that the TG is inactive, but the command:
D NET,TOPO,ORIG=NN3,DEST=NN2

issued from NN1 indicates that the TG is still active. This is because the link between NN2 and NN3 appears to VTAM®'s topology component to be two one-way TGs, and there is no CP-CP session path available to NN1 so that NN3 can report that the TG from NN3 to NN2 is inactive.

Operands

APPNCOS=cos_name
Specifies the Class of Service to be used to calculate the node weight or the TG weight.
CLEAR
Specifies whether the TDU information in the topology database is cleared after the current display operation. After you clear the TDU information, you can re-enter the command to display the TDU information that was collected in the time interval between the two commands. See z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for additional information about using the DISPLAY TOPO command with LIST=TDUINFO and LIST=TDUDIAG to diagnose TDU problems.
CLEAR=NO
No TDU information is cleared.
CLEAR=YES
When specified with LIST=TDUINFO or LIST=TDUDIAG summary (no other operands included), all TDU information is cleared.

When specified with LIST=TDUDIAG for a node or a TG, only TDU diagnostic information for the specified topology resource is cleared.

DEST=cp_name
Specifies the destination node (a control point) for a transmission group (TG), or, when used with the LIST=UNRCHTIM operand, the name of an unreachable partner (destination) on an unreachable partner path through an Enterprise Extender connection network. The cp_name value can be network qualified (netid.cpname) or a CP name without a network ID. If just the CP name is entered without a network ID, the network ID of the node on which the command is entered will be used. Depending on the value of the DSPLYWLD start option, wildcard values can be used for this operand.
FORMAT
Specifies the format of the display output of TDU information entries when LIST=TDUINFO is specified or TDU diagnostic entries when LIST=TDUDIAG is specified without node or TG operands.

When LIST=TDUINFO,SCOPE=RECENT is specified, the FORMAT operand specifies the format of the display output of each TDU information entry for each category of topology resources that were most recently included in TDUs. The TDU information categories are topology resources received and topology resources sent.

When LIST=TDUINFO,SCOPE=ACTIVITY is specified, the FORMAT operand specifies the format of the display output of each TDU information entry for each category of topology resources that were most frequently included in TDUs. The TDU information categories are topology resources received, topology resources sent, and topology resources with RSNs updated by this node.

When LIST=TDUDIAG is specified without node or TG operands, the FORMAT operand specifies the format of the display output of each TDU diagnostic entry for each category of topology resources that were most frequently included in TDUs, and that also have saved TDU diagnostic RSN update records. The TDU diagnostic categories are topology resources received, topology resources sent, and topology resources with RSNs updated by this node.

FORMAT=SHORT
Displays one line of output for each TDU information entry or each TDU diagnostic entry. FORMAT=SHORT is the default.
FORMAT=LONG
Displays two lines of output for each TDU information entry or each TDU diagnostic entry.
Result: The number of TDU information entries or TDU diagnostic entries that are displayed is determined by the NUM operand value, and is the same whether FORMAT=SHORT or FORMAT=LONG is specified.
ID
Specifies the name of the resource to display.
ID=cp_name
Specifies the name of a control point to display. The cp_name value can be network qualified (netid.cpname) or a CP name without a network ID. If just the CP name is entered without a network ID, the network ID of the node on which the command is entered will be used.
ID=name
Specifies the name of a resource to display when used with the following operands:
  • LIST=BN
  • LIST=CDSERVR
  • LIST=EN
  • LIST=ICN
  • LIST=NN
  • LIST=VN

Depending on the value of the DSPLYWLD start option, wildcard values can be used for this operand. For more information about using wildcards, see Using wildcard names.

ID=*
Specifies that all resources are to be displayed.
LIST
Specifies the type of information to be displayed.
LIST=ADJ
Displays information about nodes that are adjacent to the node specified on the ID operand. (For this command, a node is considered to be adjacent if it is attached by an active transmission group.)
LIST=ALL
Displays detailed information about the node specified on the ID operand. If you omit LIST=ALL, VTAM displays brief information about the node.
LIST=BN
Displays information about the border nodes specified on the ID operand. If you omit the ID operand, information about all border nodes is displayed. LIST=BN is not valid in end nodes or migration data hosts.
LIST=CDSERVR
Displays information about the central directory servers specified on the ID operand. If you omit the ID operand, information about all central directory servers is displayed. LIST=CDSERVR is not valid in end nodes or migration data hosts.
LIST=EN
Displays information about the end nodes specified on the ID operand, including migration data hosts (MDH). If you omit the ID operand, information about all end nodes is displayed.
LIST=ICN
Displays information about the interchange nodes specified on the ID operand. If you omit the ID operand, information about all interchange nodes is displayed. LIST=ICN is not valid in end nodes or migration data hosts.
LIST=NN
Displays information about the network nodes specified on the ID operand, including interchange nodes (ICN). If you omit the ID operand, information about all network nodes is displayed.
LIST=SUMMARY
Displays a summary, including how many nodes of each type are in the database. LIST=SUMMARY is the default.
LIST=TDUDIAG
Displays diagnostic information about topology database updates (TDUs).

When no node or TG operands are specified on the command, LIST=TDUDIAG displays summary TDU diagnostic information.

When the ID operand is specified to identify a node, LIST=TDUDIAG displays detailed diagnostic information about resource sequence number (RSN) updates for that node.

When the ORIG, DEST, and TGN operands are specified to identify a TG, LIST=TDUDIAG displays detailed diagnostic information about resource sequence number (RSN) updates for that TG.

Rule: The value LIST=TDUDIAG is valid only when it is entered on a network node.
LIST=TDUINFO

Displays information about the topology database updates (TDUs) that are received and sent by this node. This information can be used to detect a TDU war in the network. Because end nodes or migration data hosts never receive TDUs from other nodes and are never involved in TDU wars, LIST=TDUINFO is not valid in end nodes or migration data hosts. See z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for additional information about using the DISPLAY TOPO command with LIST=TDUINFO and LIST=TDUDIAG to diagnose TDU problems.

LIST=UNRCHTIM
Displays unreachable partner information for Enterprise Extender connection networks. Unreachable partner information is maintained only by network nodes and, for this reason, LIST=UNRCHTIM is valid only on network nodes. Unreachable partner information identifies paths from one node through an Enterprise Extender virtual node to a second node that is considered unreachable because of a connection network dial failure or connection network link INOP condition. When this occurs, the problem path is remembered for the period of time specified for the UNRCHTIM for that connection network. During this period, the problem path will not be considered for new sessions or HPR path switches.
To display unreachable partner information, you can specify one of the following names:
  • The name of an origin node on an unreachable partner path, using the ORIG operand
  • The name of a virtual node on an unreachable partner path, using the VRN operand
  • The name of an unreachable partner (destination) on an unreachable partner path, using the DEST operand
The ORIG, VRN, and DEST operands can be used in any combination to control the scope of the unreachable partner information that is displayed. If you omit all three of these operands, all Enterprise Extender unreachable partner information is displayed. Depending on the value of the DSPLYWLD start option, a wildcard value can be used for the ORIG, VRN, and DEST operands.
LIST=VN
Displays information about the virtual nodes specified on the ID operand. If you omit the ID operand, information about all virtual nodes is displayed.
LOCSIZE=locate_size
Specifies that only nodes which support the specified LOCATE message size are displayed.

If you specify the LOCSIZE operand, you must specify either LIST=EN or LIST=NN.

The LOCATE message size supported by a node is one of the node's resource characteristics distributed to other nodes by TDU broadcasts. Because end nodes and migration data hosts do not receive TDUs from other nodes, this parameter is valid only in network nodes and interchange nodes.

Table 1. LOCSIZE values
Value Description
1K Display all network nodes that support Locate message size of 1K.
1K+ Display all network nodes that support Locate message size of 1K and above.
2K Display all network nodes that support Locate message size of 2K.
2K+ Display all network nodes that support Locate message size of 2K and above.
4K Display all network nodes that support Locate message size of 4K.

64K+ Display all network nodes that support Locate message size of 64K and above.
128K Display all network nodes that support Locate message size of 128K.
MAX
Specifies the maximum number of unreachable partner paths that VTAM displays for this command. This operand is valid only with LIST=UNRCHTIM.
MAX=*
Specifies that the value of the DSPLYMAX start option is used to limit the display output.
MAX=number_of_unreachable_partner_paths
Specifies the number of unreachable partner paths that VTAM displays for this command. The valid range is 1–value of DSPLYMAX. The default is the value specified for the DSPLYDEF start option.

Specifying MAX limits the display output. VTAM searches only for the number of instances that you have specified. When that number is found, VTAM does not search any further. This saves processing time for the command and gives you control over the amount of display output generated by the command. If fewer unreachable partner paths are found than you have specified on MAX, VTAM displays only the unreachable partner paths that are found.

NUM
Specifies the number of TDU information entries or TDU diagnostic entries to be displayed. The default value is 10.

When LIST=TDUINFO,SCOPE=RECENT is specified, the NUM operand specifies the number of TDU information entries to be displayed for each category of topology resources that were most recently included in TDUs. The TDU information categories are topology resources received and topology resources sent.

When LIST=TDUINFO,SCOPE=ACTIVITY is specified, the NUM operand specifies the number of TDU information entries to be displayed for each category of topology resources that were most frequently included in TDUs. The TDU information categories are topology resources received, topology resources sent, and topology resources with RSNs updated by this node.

When LIST=TDUDIAG is specified without node or TG operands, the NUM operand specifies the number of TDU diagnostic information entries to be displayed for each category of topology resources that were most frequently included in TDUs, and that also have saved TDU diagnostic RSN update records. The TDU diagnostic information categories are topology resources received, topology resources sent, and topology resources with RSNs updated by this node.

When LIST=TDUDIAG is entered with the ID operand for a node or the ORIG, DEST, and TGN operands for a TG, NUM specifies the number of saved TDU diagnostic RSN update entries to be displayed. The maximum value is 50.

ORIG=cp_name
Specifies the origin node (a control point) for a transmission group (TG) or, when used with the LIST=UNRCHTIM operand, the name of an origin end node or network node on an unreachable partner path through an Enterprise Extender connection network. The cp_name value can be network qualified (netid.cpname) or a CP name without a network ID. If just the CP name is entered without a network ID, the network ID of the node on which the command is entered will be used. Depending on the value of the DSPLYWLD start option, wildcard values can be used for this operand.
SCOPE
Specifies the type of TDU information to be displayed.
SCOPE=RECENT

Displays information about topology resources that were most recently included in TDUs.

SCOPE=ACTIVITY

Displays information about topology resources with the most frequent TDU activity.

TGN=tg_number
Specifies the transmission group number of the route to be displayed. The number must be an integer in the range 1–255.
VRN=cp_name
Specifies the name of a virtual node on an unreachable partner path through an Enterprise Extender connection network. The cp_name value can be network qualified (netid.cpname) or a CP name without a network ID. If just the CP name is entered without a network ID, the network ID of the node on which the command is entered will be used. Depending on the value of the DSPLYWLD start option, wildcard values can be used for this operand.

    • The node type
  • For detailed information for a specific node, VTAM network node displays the short form plus the following information:
    • An indication of whether the node is a border node
    • An indication of whether the node is a central directory server

  • For a display of adjacent nodes, VTAM displays the short form of node information for all nodes known to be adjacent to the node specified on the ID operand. If ID specifies the name of (a) the node from which you are issuing this command, or (b) a node immediately adjacent to the node from which you are issuing this command, the display indicates whether a CP-CP session exists between this node and the adjacent nodes. The existence of a CP-CP session is not displayed if there is one or more nodes between the node from which the command is issued and the node that is named on the ID operand.

    If ID specifies the name of the node from which you are issuing this command, it is possible for the display to indicate TDU congestion, which means that many topology update transactions are in progress on the CP-CP session with an adjacent node. This is a transient condition; the congestion should clear in a short time.

    • The network-qualified name of the origin control point
    • The network-qualified name of the destination control point
    • The TG number
    • The TG status
    • The TG type
    • An indication of CP-CP session support
    • The current weight of the TG, if a Class of Service was specified on the command. If the origin or destination of the TG is a virtual node, the weight of the TG is divided by two. This smaller weight value is shown in the display.
    • The resource sequence number
    • The number of days remaining until the TG is removed from the topology database
    • An indication of whether the TG is HPR-capable
    • The capacity (line speed) of the TG. The value displayed for capacity might not exactly match the value you coded for the resource. See the z/OS Communications Server: SNA Resource Definition Reference for information about how VTAM maps the defined value to the value it actually uses.
    • The propagation delay
    • The cost per unit time
    • The cost per byte
    • The security level of the TG
    • Three user-defined parameters (default is zero)
    • The name of the physical unit if the origin node of the TG is the local node
    • The time and date when the TDU statistics counts for the TG were reset
    • The time and date when the last TDU about this TG is received, and the name of the CP that sent the TDU
    • The number of TDUs about this resource sent
    • The number of TDUs about this resource received
    • The number of TDUs about this resource accepted
    • The number of TDUs about this resource rejected
    • The number of TDUs about this resource ignored
  • For a display of a particular type of node, VTAM displays the short form of node information for each node in the topology database that matches the pattern specified on the ID operand and the type specified on the LIST operand (BN, CDSERVR, EN, ICN, NN, or VN).
  • For a display of an unreachable partner path through an Enterprise Extender connection network, VTAM displays the following information:
    • The network-qualified name of the Enterprise Extender virtual node
    • The total number of unreachable partner paths associated with the virtual node
    • If the unreachable partner limit is exceeded for the virtual node, an indication that it is exceeded, along with the lower unreachable partner threshold that must be reached before the virtual node will be used again
    • The network-qualified name of the origin node on the unreachable paths through the connection network
    • The network-qualified name of the unreachable partner (destination) on the unreachable paths through the connection network
    • The unreachable time value specified for the Enterprise Extender connection network
    • The time the unreachable time expires for the unreachable paths through the connection network
  • For topology database update (TDU) information, LIST=TDUINFO and LIST=TDUDIAG display the following information:
    • Nodes and TGs for which control vector corruption has been detected
    • Nodes and TGs whose control vectors have been received in TDUs
    • Nodes and TGs whose control vectors have been sent in TDUs
    • Nodes and TGs whose resource sequence numbers (RSNs) have been updated, and the network nodes that made the RSN updates
