[hung-pu-awareness timer-value] [hung-session-awareness timer-value] [locate-timeout
timeout-value] [max-pacing-window max-value] [remove-rscvs] [station-segmentation]
no snasw cpname
Syntax Description
netid.cpname
|
Fully qualified CP name for this node, consisting of both network ID and CP name.
|
netid
|
Partial CP name, which consists of only a network ID. If this option is selected, you must also configure the hostname or IP address operands to complete the fully qualified CP name.
|
hostname
|
(Optional) Indicates a CP name that is defined by using the hostname which is configured on the router. When configuring this operand, code a netid only. The last eight characters of the hostname are used to complete the CP name.
|
ip-address interface-name
|
(Optional) Indicates the CP name that is defined by deriving the CP name from the IP address on the interface that is indicated in the interface-name. When configured, this operand requires a netid operand. In addition, a portion of the CP name can be configured. The remaining characters of the CP name that are not configured are generated from the IP address that is indicated.
The generated characters are derived from a hexadecimal format of the IP address for the interface that is specified.
|
hung-pu-awareness timer-value
|
(Optional) Indicates the interval at which Dependent Logical Unit Requestor (DLUR) supported physical units (PUs) are checked to see if they are hung in a pending activate PU state. If a PU is in this state for two consecutive iterations of this timer, then the PU is considered hung. No attempt is made to recover the hung PU, but for diagnostic purposes message DLUR_LOG_23 (A REQACTPU RSP has not been received. Possible hung PU problem) is written to the problem determination log. If the PU later becomes activated, message DLUR_LOG_24 (A PU previously logged as possibly hung is no longer possibly hung) is issued. The valid range is from 5 to 65535 seconds. If this keyword is not specified, the default timer-value is 300 seconds.
|
hung-session-awareness timer-value
|
(Optional) Indicates the length of time when a new intermediate session that is still in a non-active state is considered hung. No attempt is made to clean up the hung session, but for diagnostic purposes message SCM_LOG_16 (Slow session activation detected) is issued. The valid range is from 5 to 65535 seconds. If this keyword is not specified, the default timer-value is 180 seconds.
|
locate-timeout timeout-value
|
(Optional) Indicates the time when an Advanced Peer to Peer Networking (APPN) Locate Search message is considered lost and is cleaned up. This will likely result in the failure of the session for which the Locate Search message was sent. When this condition occurs message DS_LOG_18 (Locate search timed out) is issued. The valid range is from 0 to 65535 seconds. A value of 0 indicates that no timeout occurs. A value from 1 to 29 seconds is rounded up to 30 seconds. If this keyword is not specified the default timeout-value is 540 seconds.
|
max-pacing-window max-value
|
(Optional) Indicates the upper limit of the Receive Pacing window size for intermediate sessions. When variable pacing is used, the Receive Pacing window size will not exceed this value. It may be necessary to configure a small Receive Pacing window size (such as 7) to improve performance when both batch and interactive traffic share the same network. The valid range is from 7 to 65535. If a value is not specified, the default is 64.
|
remove-rscvs
|
(Optional) Indicates that Route Selection Control Vectors (RSCVs) will be removed from incoming BINDs that are received from an upstream node before forwarding the BINDs downstream. Removing RSCVs from BINDs enables a downstream network node (NN) that is connected over a low entry networking (LEN) link to receive the BINDs and forward them to the destination node.
|
station-segmentation
|
(Optional) Sends all segments (for example, FIS, MIS, and LIS) to a particular LU before sending segments to another LU, which prevents PU 2.0 devices (that do not support segment interleaving) from generating sense code 80070000. Use this keyword for XID0 devices.

Usage Guidelines
You can also deactivate SNASw without removing the snasw cpname definition by using the snasw stop privileged EXEC command which enables you to stop and restart SNASw without losing the SNASw configuration. If you use no snasw cpname, all SNASw configuration commands that were entered will be lost.
Coding a CP name is required for SNASw. Only one snasw cpname command is allowed at a time. You cannot change the snasw cpname command without first deleting the previous definition by using the no form of the command. If SNASw is active, the no form deactivates it. If SNASw is inactive, using snasw cpname activates it.
Examples
The following are examples of how to configure the snasw cpname command:
snasw cpname NETA.BRANCH5
snasw cpname NETBANK2.DLUR0005
snasw cpname NETWORKA hostname
snasw cpname NETA.CP ip-address Loopback0

Usage Guidelines
The snasw dlcfilter command is typically used to limit the output of the snasw dlctrace command to a manageable amount of trace data. Running the snasw dlctrace consumes CPU and memory. Using the snasw dlctrace command limits the CPU and memory consumption to only the frames that are targeted for tracing.
Up to four different types of filters can be in place at once. If multiple filters are coded for all filters except the type filter, the frame only has to pass a single filter to be included in the trace. If the type filter is coded, the frame must pass the type filter and at least one of the other filters that is coded to be included in the trace.
Examples
The following are examples of how to configure the snasw dlcfilter command:
snasw dlcfilter link cmc1link

snasw dlctrace
To trace frames arriving and leaving SNASw, use the snasw dlctrace global configuration command. To deactivate the capture of frame data and free the storage buffer used to capture the data, use the no form of this command.
snasw dlctrace [buffer-size buffer-size-value] [file filename [timestamp]] [frame-size
frame-size-value | auto-terse] [format [brief | detail | analyzer]] [nostart]
no snasw dlctrace
Syntax Description
buffer-size buffer-size-value
|
(Optional) Specifies the size (in kilobytes) of the DLC trace buffer requested. The minimum buffer size is 100, while the maximum is 16000.
|
file filename
|
(Optional) Specifies the file name for the DLC trace buffer file when writing this file to the file server. Use the following format: protocol://host/path/filename.
|
timestamp
|
(Optional) Appends the current date and time to the end of the file when it is dumped.
|
frame-size frame-size-value
|
(Optional) Indicates the size of the frame that is traced within the DLC trace. All data beyond the size value are truncated and are not included in the trace. The default is that the entire frame is traced.
|
auto-terse
|
(Optional) Indicates LU-LU and SSCP-LU session data frames should be truncated after the SNA RH. Also truncates NMVTs on the SSCP-PU session. Control frames (for example, XID, BIND, ACTPU) are traced in their entirety.
|
format
|
(Optional) Indicates the format the DLC trace is written to when writing to a file server. Valid values are brief, detail, and analyzer:
• brief—Indicates a text file is written with a one-line-per-frame summary for each frame.
• detail—Indicates a text file is written with a frame summary line followed by a complete hexadecimal dump of the frame.
• analyzer—Indicates a binary file is generated that is readable by several popular network analyzer products. This format uses the Network Associates Sniffer file format.
|
nostart
|
(Optional) Indicates that the specified trace is not to be started when the subsystem is started.
|
Defaults
Tracing is off.
If a value for the buffer-size-value argument is not specified, then the default is 500, creating a 500 KB buffer.

Usage Guidelines
Use the snasw dlctrace command when directed by service personnel or when analysis of frame data entering and leaving SNASw is necessary.
The snasw dlctrace command copies frames into a memory buffer, which can degrade router performance. Therefore, care should be taken when using this command. When issued on a highly used system, the snasw dlcfilter command should be used in conjunction with the snasw dlctrace command to limit the output of the trace.
Use the snasw dump command to dump the trace data to a file server or the show snasw dlctrace command to display captured frames on the console.
When using the analyzer format, portions of the frame are reconstructed from their actual representation on the data link. Because of this format, portions of the data in the header portion of the frame are modified. Specifically, if there was routing information field (RIF) data present on the actual data-link frame, that information is omitted in the dlctrace. In addition, information in the LLC header (for example, Nr, Ns counts) are not reliably transferred to the traced frame. However, the remainder of the frame, including all SNA content, is a reliable representation of the frame as it appeared on the actual upstream or downstream link.

The following are examples of how to configure the snasw dlctrace command:
snasw dlctrace buffer-size 5000 file tftp://171.69.120.21/dlcfiles/dlc/trc

Syntax Description
primary-dlus-name
|
Specifies the fully qualified name of the primary DLUS (3 to 17 characters).
|
backup backup-dlus-name
|
(Optional) Indicates configuration of a backup DLUS. A backup DLUS is used when the primary DLUS is unreachable or cannot service a specific downstream device. The fully qualified name of the backup DLUS is 3 to 17 characters in length.
|
prefer-active
|
(Optional) Indicates that if an active DLUS/DLUR connection was established, an incoming PU will retry exclusively on the active DLUS connection and will not attempt to connect to a different DLUS.
|
retry interval count
|
(Optional) Indicates that the DLUR retry parameters follow this statement. The interval argument indicates the time period between attempts to connect a DLUS if one is not serving a specific PU. The count argument indicates the number of times the current or primary DLUS is retried before an attempt is made to connect to a backup or inactive DLUS.
|
once
|
(Optional) Instructs the DLUR to attempt only one retry cycle (with primary and backup (if configured) DLUS, according to either the default retry values or to the retry values specified by the retry keyword) to request DLUS services. If the service requests are not answered, the downstream link will be disconnected.
|
Defaults
If the prefer-active argument is not specified, each connected downstream station will attempt to connect to the primary DLUS or backup DLUS until the device receives DLUS services.

Usage Guidelines
Only one snasw dlus command is allowed at a time. The snasw dlus command cannot be changed without first deleting the previous definition using the no form of the command.
The prefer-active keyword supersedes the once keyword, which means that if the prefer-active keyword is configured and there is an active DLUS, then all DLUS services requests will be negotiated only with the active DLUS. The DLUR will not send DLUS service requests to other DLUSs. In this situation, the once keyword has no effect.

Usage Guidelines
Use the snasw link command to configure upstream connections to SNA data hosts, services, and DLUS nodes. Do not use this command to establish downstream connections to client workstations and devices that are serviced by the SNA switch. Configure client workstations and devices to connect into the SNA switch by configuring an outbound connection on these devices that specifies the MAC address of a port that is active on SNASw. SNASw then creates the downstream link dynamically when the workstation or device connects to SNASw.
If using the ip-dest keyword and using a DNS name instead of an IP address, the DNS name is resolved to an IP address at the time the definition is entered (or the time SNASw is started) and will remain resolved to that same address for the duration that SNASw is active. The DNS name is not resolved to an IP address each time the link is restarted.
If the link fails and SNASw switches to a non-preferred NNS (one without the nns keyword configured), SNASw will return CP-CP sessions to the preferred NNS when the NNS link becomes active again. Also, when the nns keyword is configured on a link, that link can be automatically restarted, even after the snasw stop link command is issued. See the snasw stop link command for details.
Examples
The following are examples of how to configure the snasw link command:

Usage Guidelines
The snasw location command is typically used when a LEN node link is established with a destination LU. The snasw location command allows SNASw to route session requests over the LEN node link to the resources named.
When a LEN node connects into an SNASw node, SNASw dynamically learns the CP name of the LEN and places it in its directory. In addition, SNASw dynamically learns the LU names of all LUs on the LEN that initiate independent sessions. Only define the location when an ILU on a LEN device is not sharing the node's CP name and does not initiate the first session. In all other cases the LU's location will be learned dynamically.
The directory entry is created the next time the LEN node connects in. If there is already a link to the LEN node active and you add a new snasw location statement, it will not take effect until the next time the LEN CP connects in.
Do not use the snasw location command to predefine the location of any resource that can be found dynamically using APPN searches (for example, resources on upstream APPN nodes or upstream/downstream ENs).
It is permissible to use the wildcard character "*" in location definitions to allow a definition to generate name associations for multiple devices. When using the wildcard character for this purpose, the * symbol must be coded in both the resource-name and the cpname. If any real device attaches with a CP name that matches the non-wildcard portion of the owning-cp cpname specified, a location association will be made that replaces the wildcard characters of the CPname in the position of the resource-name. For example, if a definition snasw location NETA.LU*01 owning-cp NETA.CP* is coded and CP with the name NETA.CPABCD connects in, then the resource name NETA.LUABCD01 will be defined to SNASw with owning-cp NETA.CPABCD.
You can also use the wildcard character "*" in location definitions to allow a specific device to connect under different CP names, but a single device cannot connect under multiple CP names at the same time. In this case, the * symbol must be used in only the cpname argument and not the resource-name argument. When the device connects with a CP name that matches the non-wildcard portion of the cpname argument, a corresponding location association will be made for the resource-name with that CP name.
Examples
The following is an example of how to configure the snasw location command:
snasw location NETA.INDEPLU owning-cp NETA.LENHOSTA

no snasw port port-name
Syntax Description
port-name
|
The one- to eight-character name for the port. This argument is used to refer to this port in informational messages and the show snasw port command.
|
interface-name
|
The name of the interface over which the port will communicate. Allowable interfaces are Token Ring, Ethernet, VLAN, or loopback.
|
hpr-ip
|
Indicates that the port is High-Performance Routing (HPR)/IP.
|
ldlc
|
(Optional) Overrides the default Logical Data Link Control (LDLC) parameters for all links which use the port. This keyword allows the LDLC parameters for SNASw links to be configured to match those at the other Rapid Transport Protocol (RTP) endpoint, which is often a host z/OS or CS/390.
|
liveness-time
|
(Optional) Number of seconds for the liveness timer. This parameter matches the z/OS or CS/390 LIVTIME keyword. The allowed range is from 5 to 25 seconds, and the default is 2 seconds.
|
t1-retry-time
|
(Optional) Number of seconds between T1 retry attempts. This parameter matches the z/OS or CS/390 SRQTIME keyword. The allowed range is from 3 to 20 seconds, and the default is 2 seconds.
|
t1-retry-count
|
(Optional) Number of times to retry before the HPR-IP TG becomes inoperative. This parameter matches the z/OS or CS/390 SRQRETRY keyword. The allowed range is from 3 to 9 retries, and the default is 10 retries.
|
maxbtu max-btu-size
|
(Optional) Indicates the maximum basic transmission unit (BTU) size for the remote end (both inbound and outbound). This value is used in XID3 negotiation. The valid range is from 1 to 17800.
|
vnname virtual-node-name
|
(Optional) Indicates the network qualified virtual node name 3 to 17 characters) of the connection network being defined.
|
nostart
|
(Optional) Indicates that the port will not open automatically when defined.
|
vdlc ring-group
|
Indicates that the port is virtual data-link control (VDLC). No interface-name argument is required. The ring-group argument indicates the source-bridge ring group of which this VDLC port is a member.
|
mac mac-address
|
Indicates the virtual source MAC address used for the VDLC port.
|
virtual-TokenRing-interface-name
|
Indicates the name of the virtual Token Ring interface.
|
conntype nohpr | len | dyncplen
|
(Optional) The conntype keyword indicates the connection type for the port. The connection type can be set to one of three values: nohpr, len, or dyncplen. If this keyword is not configured, HPR-capable links are established. The nohpr keyword indicates that the HPR is not supported but Advanced Peer-to-Peer Networking (APPN) connections with control point (CP)-CP sessions are permitted. The len keyword indicates that APPN connections are not allowed; only low-entry networking node (LEN) node-level connectivity is negotiated. The dyncplen keyword (similar to LEN node in functionality) also replaces the cpname keyword. This option is specifically intended for users with XID3-capable devices that send CP names, but whose CP names configured on these devices have not been configured uniquely across the devices. Therefore, a default cpname must be generated to have a properly functioning APPN connection management and directory function.
|
hpr-sap hpr-sap-value
|
(Optional) Indicates the local HPR-service access point (SAP) value.
|
max-links link-limit-value
|
(Optional) Indicates the number of links permitted on this port. When this link limit is reached, the port will not respond to inbound connection requests from stations attempting to connect to this port. Outbound connections are still permitted. The max-links can be coded only on VDLC and Virtual Token Ring port types.
|
maxbtu max-btu-size
|
(Optional) Indicates the maximum basic transmission unit (BTU) size for the remote end (both inbound and outbound). This value is used in XID3 negotiation. The valid range is from 1 to 17800.
|
nns-required
|
(Optional) Enables configurations with redundant downstream MAC addresses to only allow SNASw nodes that have appropriate upstream connectivity to accept and retain connections from downstream devices.
• When a port is configured with the nns-required keyword, the port does not respond to downstream connection requests unless this SNASw node has active CP-CP sessions to an upstream network management system (NNS).
• If a connection has already been made through this SNASw node and then upstream NNS CP-CP connectivity is lost, this SNASw node deactivates all non-HPR links using this port that do not have active logical unit (LU)-LU or Intermediate Session Routing (ISR) sessions.
Note This keyword is relevant only for ports that will be accepting downstream connections from devices. It is not relevant for upstream ports.
|
sap sap-value
|
(Optional) Indicates the local SAP (LSAP) value.
|
Defaults
No default behaviors or values.

Usage Guidelines
More than one port can be configured (with different port names). A configured port cannot be redefined without first deleting the port using the no form of the port command.
Note
Two ports cannot be defined on the same interface unless different values are configured for the `sap' and `hrp-sap' keywords on the ports.
Note
SNASw ports do not dynamically adjust to interface configuration changes that are made when SNASw is active. For example, if you change an interface MAC address or MTU, SNASw may not recognize the new value. If you want to make changes to an interface and want SNASw to adjust to the new interface changes, you may need to either delete and redefine the port that is using that interface or stop and restart SNASw.
The interface must be defined before the ports that use them are defined and activated.
SNASw does not support EtherChannel interfaces (neither port-channel interfaces nor Fast Ethernet interfaces configured with the channel-group command). Do not try to configure a SNASw port with either of these EtherChannel interface types.
Examples
The following are examples of how to configure the snasw port command:
snasw port SRBG Virtual-TokenRing0 conntype nohpr
snasw port UPSTREAM TokenRing1/1
snasw port dlswport vdlc 30 mac 4000.33333.4444
snasw port HPRIP hpr-ip Loopback0
snasw port TRVLAN Vlan1/1 vnname NETA.CONNET

Usage Guidelines
The arguments for this command should be tuned to match the values specified at the other end of the RTP connection. This endpoint could be another SNASwitch router or any other HPR-capable control point, which will most often be an IBM z/OStm mainframe. In this case, you should match the settings of the HPRPST start option.
The value for each path-switch timer argument must be greater than or equal to the value for the next highest priority timer argument. In other words, the low-priority argument >= medium-priority argument >= high-priority argument >= network-priority argument.
Examples
The following example tunes the RTP path-switch timers:
router(config)# snasw rtp pathswitch-timers 160 80 40 20

Usage Guidelines
Use the snasw start cp-cp command if CP-CP sessions fail permanently or temporarily, but beyond the timeframe for automatic CP-CP session retry. If the current state of the node mandates that CP-CP sessions cannot be started to the partner (for example, CP-CP sessions already exist on a different upstream link) or no active adjacent CP matches the cpname named, the command fails.
Typically, SNASw automatically activates CP-CP sessions as necessary and the snasw start cp-cp command is rarely needed. Frequent CP-CP session failure beyond the timeframe for automatic session retry indicates a problem, and should be reported.
Examples
The following is an example of the snasw start cp-cp command:
snasw start cp-cp NETA.CMCHOST

Usage Guidelines
If the primary NN server (uplink) fails, CP-CP sessions are established with a backup, if one is available. When the link to the primary recovers, SNASw retains the CP-CP sessions established with the backup and does not automatically switch back to the primary. To force SNASw to switch back to the primary, use the snasw stop cp-cp command. (If the link to the backup fails, SNASw does switch back to the primary automatically.)
You can also use the snasw stop cp-cp command to clear some fault scenarios, such as hung or nonresponsive CP sessions, allowing the SNA switch to potentially restart sessions with the same or alternate destination LU.

Usage Guidelines
Use the snasw stop link command to deactivate a link to a specified partner CP. All non-HPR sessions established using the link are disconnected. HPR sessions are disrupted only if there is no alternate route available.
Normally a link stopped with the snasw stop link command must be restarted by issuing the snasw start link command. However, it will be automatically restarted under the following conditions:
•
The nns keyword is specified on the snasw link command, and
•
The SNASw CP did not already re-establish CP-CP sessions with a network node server over another upstream link.
