llc2template \- Description of LLC2 configuration file
|
|
.SH DESCRIPTION
|
|
An LLC2 configuration file contains 14 lines of
|
|
various parameters.
|
|
Configuration of the llc2 driver is performed by
|
|
.IR "lltune"(1M)
|
|
using files with this format.
|
|
These parameters are detailed
|
|
below:
|
|
.PP
|
|
.IP " 1) \fBN2_VAL\fR" 12
|
|
Maximum number of times that a Protocol Data Unit is sent following
|
|
the expiry of the Acknowledgement Timer, the P-bit timer, or the Reject
|
|
Timer. This parameter also limits the number of times an RR is sent with
|
|
the P-bit set when remote busy is true and the Busy timer expires.
|
|
|
|
.IP " 2) \fBT1_VAL\fR"
|
|
The time interval during which the LLC expects to receive an
|
|
acknowledgement to an outstanding I Protocol Data Unit(PDU) or an expected
|
|
response to a sent unnumbered PDU (units in 0.1 seconds).
|
|
|
|
.IP " 3) \fBTPF_VAL\fR"
|
|
The time during which the LLC2 expects to receive a PDU with
|
|
the F-bit set to 1 in response to a command with the P-bit
|
|
set to 1. Value is in 0.1 second units and should be less than
|
|
the value specified for the Acknowledgement Timer.
|
|
|
|
.IP " 4) \fBTREJ_VAL\fR"
|
|
The time interval during which the LLC2 expects to receive a reply
|
|
to a sent REJ TPDU (units in 0.1 seconds).
|
|
|
|
.IP " 5) \fBTBUSY_VAL\fR"
|
|
The time interval during which the LLC2 waits for an indication of
|
|
the clearance of a busy condition at the other LLC2 (units in 0.1 seconds).
|
|
|
|
.IP " 6) \fBTIDLE_VAL\fR"
|
|
The time interval during which the LLC2 expects to receive a PDU
|
|
from the other LLC2.
|
|
|
|
.IP " 7) \fBACK_DELAY\fR"
|
|
RR delay time (units in 0.1 seconds).
|
|
|
|
.IP " 8) \fBNOTACK_MAX\fR"
|
|
Maximum number of unacknowledged Rx I-frames.
|
|
|
|
.IP " 9) \fBTX_WINDOW\fR"
|
|
Transmit window (if no XID received).
|
|
|
|
.IP "10) \fBTX_PROBE\fR"
|
|
The position before the window is closed at which an I PDU
|
|
is sent with the P-bit set to solicit an acknowledgement from
|
|
the receiver.
|
|
|
|
.IP "11) \fBMAX_I_LEN\fR"
|
|
Maximum size of LLC2 I frame. LLC2 requires all incoming I frames
|
|
above a certain size to be rejected by a FRMR.
|
|
This parameter specifies the maximum size of
|
|
data you may receive starting from the LLC2 protocol header.
|
|
.sp 1
|
|
In a X.25 network, it is constructed as (maximum X.25 data length + X.25
|
|
protocol header length + LLC2 protocol header length).
|
|
In a SNA network, it is constructed as (maximum SNA data length + SNA
|
|
request header length + SNA transmission header length + LLC2 protocol
|
|
header length).
|
|
.IP "12) \fBXID_WINDOW\fR"
|
|
XID window size (receive window),
|
|
when the remote window size is unknown or zero.
|
|
|
|
.IP "13) \fBXID_NDUP\fR"
|
|
Duplicate MAC XID count (0 means no test).
|
|
|
|
.IP "14) \fBXID_TDUP\fR"
|
|
Duplicate MAC XID time (units in 0.1 seconds).
