Properties
Name
Data Type: String Qualifiers: MAXLEN(8), TOUPPERCASE Access Type: Read-Only
The mode name.
Comment
Data Type: String Qualifiers: MAXLEN(25) Access Type: Read/Write
An optional comment field.
SessionLimit
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(15000) Access Type: Read/Write
The maximum number of parallel sessions allowed with this mode.
MinContWin
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(15000) Access Type: Read/Write
The minimum contention winner limit.
PartMinContWin
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(15000) Access Type: Read/Write
The partner minimum contention winner limit.
AutoActivate
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(15000) Access Type: Read/Write
The number of contention winner sessions to be activated for the local LU whenever the connection for this mode is started.
Priority
Data Type: Boolean Access Type: Read/Write
true to give preference to communication with this mode over communication with a low-priority mode; otherwise, false.
TxPacing
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(63) Access Type: Read/Write
The maximum number of frames for the local LU to send without an SNA pacing response from the partner LU. Setting TxPacing to 0 indicates a unlimited number of frames.
RxPacing
Data Type: sint32 Qualifiers: MINVALUE(0), MAXVALUE(63) Access Type: Read/Write
The maximum number of frames for the local LU to receive from the partner LU before the local LU sends an SNA pacing response. Setting RxPacing to 0 (zero) indicates a unlimited number of frames.
TxRu
Data Type: sint32 Qualifiers: MINVALUE(256), MAXVALUE(65527) Access Type: Read/Write
The maximum size for RUs sent by the TPs on the local system.
RxRu
Data Type: sint32 Qualifiers: MINVALUE(256), MAXVALUE(65527) Access Type: Read/Write
The maximum size for RUs received from the TPs on the remote system.
MaxSendCompression
Data Type: sint32 Access Type: Read/Write
The maximum compression allowed when sending. The following table describes the possible values for MaxSendCompression.
| Values | Description |
|---|---|
| 0 | None |
| 1 | RLE |
| 2 | LZ9 |
MaxRcvCompression
Data Type: sint16 Access Type: Read/Write
The maximum compression allowed when receiving. The following table describes the possible values for MaxRcvCompression.
| Values | Description |
|---|---|
| 0 | None |
| 1 | RLE |
| 2 | LZ9 |
AllowLZandRLE
Data Type: Boolean Access Type: Read/Write
true to compress data using RLE before being further compressed using LZ9; otherwise, false. AllowLZandRLE is valid only if you are using LZ9.
EndpointOnly
Data Type: Boolean Access Type: Read/Write
true to allow intermediate nodes to use compression if one of the endpoints does not support or otherwise does not use compression; otherwise, false.
Remarks
MsSna_AppcMode defines properties of an LU 6.2 session.
Requirements
Platforms: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows 11, and Windows 10
