Note that you need to remove all IP related configurations on the interface before 
enabling SDLC, because SDLC cannot underlie the IP protocol. For example, you 
need to delete the IP address of the interface.

length: The maximum number of information frames the router can receive before 
it must send an acknowledgment, in the range of 1 to 127.

Use the llc2 max-ack command to configure namely the maximum number of 
information frames the device can receive before it must send an 
acknowledgment to the peer router.

Use the undo llc2 max-ack command to restore the default setting.

By default, the maximum number of information frames the router can receive 
before it must send an acknowledgment is 3.

# Set the maximum number of information frames the router can receive before it 
must send an acknowledgment to 5 on Ethernet 1/0.
