Step | Command | Remarks |
---|---|---|

2. Enter interface view. | interface interface-type interface-number | N/A |
3. Configure the length of the SDLC output queue. | sdlc max-send-queue length | Optional. 50 by default. |
4. Configure the maximum number of consecutive frames the device can send before receiving an acknowledgement from the peer. | sdlc window length | Optional. 7 by default. |
5. Configure the modulus value of SDLC. | sdlc modulo { 8 | 128 } | Optional. 8 by default. |
6. Configure the maximum SDLC PDU size. | sdlc max-pdu number | Optional. 265 bytes by default. The maximum PDU size of some PU2.0 devices is 265 bytes, and that of an IBM AS/400 is 521 bytes. This maximum PDU size should be configured to be the same as on the peer SDLC device. |
7. Configure the maximum number of SDLC transmission retries. | sdlc max-transmission retries | Optional. 20 by default. |
8. Configure the local and remote SAP addresses for SDLC-to-LLC2 frame conversion. | sdlc sap-map local lsap sdlc-addr | Optional. 0x04 by default. A SAP address refers to the address of one or more application processes running on a computer or network device. |
sdlc sap-map remote dsap sdlc-addr | ||
9. Enable SDLC simultaneous mode. | sdlc simultaneous | Optional. Alternate mode by default. Generally, this configuration is not required. |
10. Configure the SDLC polling interval. | sdlc timer poll mseconds | Optional. 1000 ms by default. |
11. Configure the amount of time the primary SDLC station waits for an acknowledgment from the receiving secondary station. | sdlc timer ack mseconds | Optional. 3000 ms by default. |
12. Configure the amount of time a secondary SDLC station waits for an acknowledgment from the receiving primary station. | sdlc timer lifetime mseconds | Optional. 500 ms by default. |
