5.3.9 T2-RECEIVE-ACK-TIMER
Delays acknowledging I-format frames. This timer starts when the router receives an I-frame and stops when the
router sends an acknowledgment. If this timer times out, LLC2 sends an acknowledgment as soon as possible. T2
must be set to a value that is lower than T1 to ensure the remote LLC2 peer receives the delayed acknowledgment
before the T1 timer expires. Values range from 1 to 2560. Default is 1 (100 ms), which disables the timer.
Syntax:
ethernetX/X LLC config>t2-receive-ack-timer <value>
Example:
ethernet0/0 LLC config>t2-receive-ack-timer 1
ethernet0/0 LLC config>
5.3.10 TI-INACTIVITY-TIMER
This timer times out when LLC does not receive a frame during a specified time period. When this occurs, the LLC
transmits an RR until the other LLC station responds or the N2 retry count is exceeded. Values range from 1s to
4m16s. Default is 30 seconds.
Syntax:
<interface name> LLC config>ti-inactivity-timer <value>
Example:
ethernet0/0 LLC config>ti-inactivity-timer 30
ethernet0/0 LLC config>
5.3.11 TW-TRANSMIT-WINDOW
Maximum number of I-frames that can be sent before receiving an RR. Assuming the other end of the LLC session
can actually receive this many consecutive I-frames, and the router has enough heap memory to keep copies of
these frames until an acknowledgment is received, increasing this value may increase the performance. Values
range from 1 to 127. Default is 2.
Syntax:
ethernetX/X LLC config>tw-transmit-window <value>
Example:
ethernet0/0 LLC config>tw-transmit-window 2
ethernet0/0 LLC config>
5.3.12 EXIT
Returns to the LAN interface (Ethernet, Token Ring or Ethernet subinterface) configuration menu.
Syntax:
ethernetX/X LLC config>exit
Example:
ethernet0/0 LLC config>exit
ethernet0/0 config>
