DSPU and SNA Service Point Configuration Commands

DSPU and SNA Service Point Configuration Commands

This chapter describes the commands you use to configure the downstream physical unit (DSPU) feature, which provides a gateway facility for downstream Systems Network Architecture (SNA) physical units (PUs), and SNA Service Point support. For DSPU and SNA Service Point configuration tasks and examples, refer to the "Configuring DSPU and SNA Service Point Support" chapter of the Bridging and IBM Networking Configuration Guide.

dspu activation-window

Use the dspu activation-window global configuration command to define the number of activation request units (RUs) and response messages (such as ACTLUs or DDDLU NMVTs) that can be sent without waiting for responses from the remote PU. Use the no form of this command to return to the default window size.

dspu activation-window window-size
no dspu activation-window
Syntax Description

window-size

Number of outstanding unacknowledged activation RUs. The default is 5.

Default

The default window size is 5 outstanding unacknowledged activation RUs.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

You do not typically need to define the number of activation RUs, but doing so can enhance activation performance in some situations. Increasing the DSPU activation window allows more LUs to become active in a shorter amount of time (assuming the required buffers for activation RUs are available). Conversely, decreasing the DSPU activation window limits the amount of buffers the DSPU can use during PU/LU activation. This command provides pacing to avoid depleting the buffer pool during PU activation.

Example

In the following example, the DSPU activation window is configured to 10. The DSPU can send up to 10 activation RUs without a response from the remote PU. However, the DSPU cannot send any additional activation RUs until a response is received. The DSPU can only have 10 activation RUs awaiting response at any given time.

dspu activation-window 10

dspu default-pu

Use the dspu default-pu global configuration command to enable the default PU feature to be used when a downstream PU attempts to connect, but does not match any of the explicit PU definitions. Use the no form of this command to disable the default PU feature.

dspu default-pu [window window-size] [maxiframe max-iframe]
no dspu default-pu [window window-size] [maxiframe max-iframe]
Syntax Description

window window-size

(Optional) Send and receive window sizes used across the link. The range is 1 to 127. The default is 7.

maxiframe max-iframe

(Optional) Maximum size (in bytes) of an I-frame that can be transmitted or received across the link. The range is 64 bytes to 18,432 bytes. The default is 1472.

Defaults

The default window size is 7.
The default maximum I-frame size is 1472.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

If the DSPU default PU is not defined, a connection attempt by a downstream PU that does not match any explicit PU definition is rejected.

The dspu default-pu command must be followed by at least one dspu lu command to define which pool the default LUs will be assigned from. Note that default LUs cannot be defined as dedicated LUs from a host.

The maximum I-frame size includes the SNA transmission header (TH), request header (RH), and request unit (RU), but does not include the DLC header. The DSPU feature segments frames being transmitted to fit within this frame size. If an XID is received from a remote PU which indicates that it supports a different maximum I-frame size, then the smaller of the two values is used.

Example

In the following example, the default PU feature is enabled with a window size of 5 and a maximum I-frame size of 128. Each default PU can have up to 3 LUs assigned from the hostpool pool of LUs.

dspu pool hostpool host ibm3745 lu 2 254

(Optional) Interval of inactivity (in minutes) on either the SSCP-LU or LU-LU sessions, which will cause the downstream LU to be disconnected from the upstream LU. The default is disabled.

Default

The inactivity-timeout is disabled.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

You can include multiple dspu pool commands that specify the same pool name. In this way, an LU pool can include several LU ranges from the one host PU, or it can include LUs from different host PUs. The LUs from host host-name starting at lu-start and ending with lu-end, inclusive, will be included in the pool pool-name. For the LUs in this pool, if there is no traffic on either the SSCP-LU or LU-LU sessions for the inactivity-timeout number of minutes, the downstream LU will be disconnected from the upstream LU, and the upstream LU will be allocated to any downstream LU waiting for a session. A value of zero for inactivity minutes means no timeouts. (Note that the inactivity-timeout applies to all LUs in this pool, not just the LUs defined by this dspu pool command. The last value configured will be used.)

Examples

The following example defines a pool of host LUs. A pool of 253 host LUs is defined with all LUs supplied from the ibm3745 host PU:

dspu host ibm3745 xid-snd 065000001 rmac 4000.3745.0001 
dspu pool hostpool host ibm3745 lu 2 254

The following example defines multiple pools and defines a disjoint pool of host LUs. One pool with a total of 205 host LUs and second pool with a total of 48 host LUs are defined with all LUs supplied from the same ibm3745 host PU. Host LUs with addresses 2 to 201 and 250 to 254 are defined in hostpool1. Host LUs with addresses 202 to 249 are defined in hostpool2.

dspu host ibm3745 xid-snd 065000001 rmac 4000.3745.0001 
dspu pool hostpool1 host ibm3745 lu 2 201
dspu pool hostpool2 host ibm3745 lu 202 249
dspu pool hostpool1 host ibm3745 lu 250 254

The following example defines a pool of LUs from multiple hosts. A pool of 506 host LUs is defined with 253 LUs supplied by the ibm3475 host PU and 253 supplied by the ibm3172 hostPU.

dspu host ibm3745 xid-snd 065000001 rmac 4000.3745.0001

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

The local SAP address must be enabled by one of the following commands:

dspu enable-pu (Ethernet, Frame Relay, Token Ring, FDDI) lsap
dspu ncia enable-pu lsap
dspu rsrb enable-pu lsap
dspu vdlc enable-pu lsap

The send and receive maximum I-frame size includes the SNA TH and RH, but does not include the data link control header. The DSPU feature will segment frames being transmitted to fit within this frame size. If an XID is received from a remote PU which indicates that it supports a different maximum I-frame size, then the smaller of the two values is used.

If you want the DSPU to attempt a ConnectOut to the remote node using the dspu start command, you must configure the rmac keyword and argument. If you want this PU to match against a ConnectIn attempt, then several combinations of rmac, rsap, xid-rcv are possible. The matching algorithms are as follows:

If an XID is received from a remote PU which indicates that it supports a different maximum I-frame size, then the smaller of the two values is used.

Examples

In the following example, a downstream PU is defined with only the MAC address and SAP address specified. A downstream PU that attempts an incoming connection to the DSPU will only be accepted if the remote MAC/SAP address matches the configured values for this downstream PU (and the proper local SAP address is enabled).

dspu pu ciscopu rmac 1000.5AED.1F53 rsap 20
dspu lu 2 5 pool hostpool
interface tokenring 0
dspu enable-pu lsap 8

In the following example, a downstream PU is defined with only an xid-rcv value. Any downstream PU that attempts an incoming connection specifying the xid-rcv value, 05D00001, will be accepted without regard to remote MAC or SAP address (although the proper local SAP address must be enabled).

dspu pu ciscopu xid-rcv 05d00001
dspu lu 2 5 pool hostpool
interface tokenring 0
dspu enable-pu lsap 8

In the following example, a downstream PU is defined with xid-rcv, rmac, and rsap keywords. Any downstream PU that attempts to ConnectIn to the DSPU must match all three configured values for the connection to be accepted (the proper local SAP address must also be enabled).

dspu pu ciscopu xid-rcv 05d00001 rmac 1000.5AED.1F53 rsap 20

Usage Guidelines

This command first appeared in Cisco IOS Release 10.3.

The bridge number parameter can be specified only once in a configuration.

Use the dspu rsrb command to enable DSPU host and downstream connections to be established across an RSRB link.

If the local-ack parameter is specified on the source-bridge remote-peer statement, DSPU will establish host connections across RSRB using local acknowledgment. DSPU cannot support local acknowledgment for downstream PU connections across RSRB.

Examples

The following example defines DSPU to start a connection to the host across an RSRB link (without local acknowledgment). The DSPU is identified by its local ring number 88 and its virtual MAC address 4000.FFFF.0001. When the DSPU attempts an outgoing connection to the ibm3745 host, the connection will be established across the RSRB virtual ring 99.
