Set
Use the set command to configure the LLC.
Attention: Changing LLC parameters from the defaults can affect how the LLC
protocol works.

count
n2-max-retry
The maximum number of retries by LLC protocol. For example, N2 is the
maximum number of times the LLC transmits an RR without receiving an
acknowledgment when the inactivity timer expires. Default is 8. Minimum is
1. Maximum is 127.
Example:
set n2-max-retry
Max Retry value (N2) [8]?
n3-frames_rcvd-before-ack
This value is used with the T2 timer to reduce acknowledgment traffic for
received I-frames. Set this counter to a specified value. Each time an
I-frame is received, this value decrements. When this counter reaches 0 or
the T2 timer expires, an acknowledgment is sent. Default is 1. Minimum is
1. Maximum is 255.
Example:
set n3-frames_rcvd-before-ack
Number I-frames received before sending ACK(N3) [1]?
rw-receive-window
Indicates the maximum number of unacknowledged sequentially numbered
I-frames that an LLC can receive from a remote LLC peer. This value must
be equal to or less than 127.
Example:
set rw-receive-window
Receive Window (Rw), 127 Max. [2]?
nw-acks-to-inc-ww
This field is set to a default value of 1.
t1-reply-timer
This timer expires when the LLC fails to receive a required acknowledgment
or response from the other LLC station. When this timer expires, an RR is
sent with the poll bit set and T1 is started again. If the LLC receives no
response after the configured maximum number of retries (N2), the link
underneath is declared inoperative. Default is 1. Minimum is 1. Maximum is
256.
