LLC2TEMPLATE(4)LLC2TEMPLATE(4)NAMEllc2template - Description of LLC2 configuration file
DESCRIPTION
An LLC2 configuration file contains 14 lines of various parameters.
Configuration of the llc2 driver is performed by lltune(1M) using files
with this format. These parameters are detailed below:
1) N2_VAL 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.
2) T1_VAL 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).
3) TPF_VAL
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.
4) TREJ_VAL
The time interval during which the LLC2 expects to receive a
reply to a sent REJ TPDU (units in 0.1 seconds).
5) TBUSY_VAL
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).
6) TIDLE_VAL
The time interval during which the LLC2 expects to receive a
PDU from the other LLC2.
7) ACK_DELAY
RR delay time (units in 0.1 seconds).
8) NOTACK_MAX
Maximum number of unacknowledged Rx I-frames.

9) TX_WINDOW
Transmit window (if no XID received).
10) TX_PROBE
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.
11) MAX_I_LEN
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.
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).
12) XID_WINDOW
XID window size (receive window), when the remote window size
is unknown or zero.
13) XID_NDUP
Duplicate MAC XID count (0 means no test).
14) XID_TDUP
Duplicate MAC XID time (units in 0.1 seconds).
