5.3.6 NW-ACKS-TO-INC-WW
When sending I-frames is not enabled, LLC goes into a mode where the working window (Ww) is set back to 1 be-
fore slowly reaching its normal size (Tw). This is known as the dynamic window algorithm. This value is the number
of I-frames LLC must receive before incrementing Ww by 1. Values range from 1 to 127. Default is 1.
Syntax:
ethernetX/X LLC config>nw-acks-to-inc-ww <value>
Example:

5.3.7 RW-RECEIVE-WINDOW
Maximum number of unacknowledged sequentially numbered I-frames that LLC can receive from a remote LLC
peer. This value must be equal to, or lower than, 127. Default is 2.
Syntax:
ethernetX/X LLC config>rw-receive-window <value>
Example:
ethernet0/0 LLC config>rw-receive-window 2
ethernet0/0 LLC config>
5.3.8 T1-REPLY-TIMER
Times out when LLC fails to respond on receiving a required acknowledgment or a response from another LLC sta-
tion. When this timer times out, an RR is sent with the poll bit set and T1 is re-started. If LLC receives no response
after the maximum number of retries configured has timed out (N2), the lower link is declared inoperative. Values
range from 1s to 4m16s. Default is 1 second.

ethernet0/0 LLC config>t1-reply-timer 1
