Description

The DlurLinkSta parameter specifies a LinkStation for downstream DLUr nodes. Using the ADD command, you specify a DLUr link station for a port, including the DLUr's destination address and downstream physical unit name (DSPU).

Values

<max_btu_size>

Specifies the maximum BTU size for the DLUr link station. The value range is 256-8912.

<dest media addr>

Specifies the destination MAC address for the DLUr link station. If you have specified the -SYS MacAddrFormat parameter as noncanonical, enter the address in noncanonical format; if you have not changed the -SYS MacAddrFormat parameter, enter the address in noncanonical format but add the prefix "NcMac."

<dspu name>

Specifies the downstream PU (DSPU) name. If the host will be activate the session with the DLUr link station, then the DSPU name you configure here must match the name on the host configuration.

Sap

Enters the service access point (SAP) of the DLUr link station. The valid range in hexadecimal of SAP values for this parameter is from 0x4 to 0xEC in multiples of 4. The default SAP value is 0x04. Note that the SAP is always displayed using the hexadecimal value, but is not shown with the 0x prefix.

Nodeid

Specifies the node ID that is checked by the XID. The node ID must be entered in hex and must include all eight hex digits. A node ID of 0x00000000 means that the Node ID will not be checked.

<LinkName>

Specifies the name assigned to the link. All link names must be unique on the local network node. For example, you cannot use the same link name on more than one port, and you cannot use the same link name for two types of links (such as for adjacent link stations or DLUr link stations) at the same time. The link name is limited to eight characters, and cannot start with special characters. If no link name is specified, the system assigns a link name LINKXXXX where XXXX is a number between 0001 and 9999. When deleting a DLUr link station, you must specify the link name.

Dlus

Specifies the primary DLUs name used by this DLUr link station. If no primary DLUs is specified, then the DLUs configured with the DlurDefaults parameter are used. To remove the primary DLUs name, enter Undef.

Backup

Specifies the backup DLUs name used by this DLUr link station. If no backup DLUs is specified, then the backup DLUs configured with the DlurDefaults parameter are used.To remove the backup DLUs name, enter Undef.

TGprof

Specifies the TG profile assigned to the DLUr link station. The TG profile is a set of default values that apply to the link if chosen. When a TG profile is specified, the proper effective capacity and propagation delay values are assigned to the link station based on the link speed of the media. For a list of TG profiles, see Table 15 earlier in this chapter.

AutoStart

If you specify Yes, the link is automatically activated when the local network node is enabled, and is restarted automatically if the link stops. If you specify No, the link is not automatically started and you will have to activate the link using the SET -APPN LinkStaCONTrol command. The default value is yes. In the SHow -APPN DlurLinkSta display, AutoStart support is shown in the "A" column.

CPSess

Specifies whether CP-CP sessions is activated with the adjacent node. If you specify yes, CP-CP sessions are activated with the node, and if you specify no, they are not. The default value is no if the adjacent node type is a network node, and yes if the adjacent node type is an end node or the node type is set to LEARN. In the SHow -APPN DlurLinkSta display, CP-CP session support is shown in the "CP" column.

PU2

Specifies whether the link station is a PU 2.0 node or a PU 2.1 node. If you specify Yes, the link supports communication to PU 2.0 nodes but supports DLUr services only (and not APPN services). If you specify No, the link supports communication to PU 2.1 nodes and can support both APPN and DLUr over the same link. The default is No.

If you specify Yes, the link can be activated by the host. If you specify No, the link cannot be activated by the host. Specify Yes if the downstream node does not support APPN, or you do not want APPN services from the local network node.

HPR

Specifies whether the link station supports High Performance Routing (HPR) on this link. If you specify Yes, then HPR is supported on the link between the local node and the DLUR link station. If you specify No, HPR is supported, and the link uses Intermediate Session Routing (ISR). The default is Yes, which means HPR is supported by default, so if you want the adjacent link station to support only ISR, you must specify No. If HPR is set to Yes, then PU2 must be set to No.

ErrorRecovery

For HPR links only, specifies whether link-level error recovery is used for an outgoing connection on the link. If you specify Yes, error recovery is preferred, but can be negotiated down. If you specify No, error recovery for HPR will not take place. If you want link level error recovery for the incoming connection, then you must set the ErrorRecovery value for the PortDef parameter (see "PortDef" later in this chapter). The default is the ErrorRecovery value defined using the PortDef parameter (the port the adjacent link station belongs to). If you use link-level error recovery, additional overhead is created on your links. This value is only valid if the HPR value is set to "Yes."
