Configuring LLC2 parameters
SNA was designed to transmit LLC2 frames over Ethernet. Modify some LLC2 parameters by using LLC2 related commands.
To configure LLC2 parameters:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Configure the maximum number of information frames the router can receive before it must send an acknowledgement. | llc2 max-ack length | 3 by default. |
4. Configure the maximum number of consecutive information frames the router can send before receiving an acknowledgement from the peer. | llc2 receive-window length | Optional. 7 by default. |
5. Configure the LLC2 output queue length. | llc2 max-send-queue length | Optional. 50 by default. |
6. Configure the modulus value of LLC2. | llc2 modulo { 8 | 128 } | Optional. 128 by default. |
7. Configure the number of LLC2 transmission retries. | llc2 max-transmission retries | Optional. 3 by default. |
8. Configure the maximum LLC2 PDU. | llc2 max-pdu length | Optional. 1493 bytes by default. |
9. Configure the LLC2 local acknowledgment delay time. | llc2 timer ack-delay mseconds | Optional. 100 ms by default. |
10. Configure LLC2 acknowledgment waiting time. | llc2 timer ack mseconds | Optional. 200 ms by default. |
11. Configure the LLC2 busy-station polling interval. | llc2 timer busy mseconds | Optional. 300 ms by default. |
12. Configure the LLC2 P/F waiting time. | llc2 timer poll mseconds | Optional. 5,000 ms by default. |
13. Configure the LLC2 REJ status time. | llc2 timer reject mseconds | Optional. 500 ms by default. |
14. Configure the LLC2 POLL timer. | llc2 timer detect mseconds | Optional. 30,000 ms by default. |
