Configuring basic functions of a CPOS interface
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CPOS interface view. | controller cpos cpos-number | N/A |
3. (Optional.) Configure the interface description. | description text | By default, the description of a CPOS interface is interface name Interface, for example, Cpos2/1/1 Interface. |
4. Set the framing format. | frame-format { sdh | sonet } | The default setting is SDH. |
5. Set the clock mode. | clock { master | slave } | The default setting is slave. |
6. (Optional.) Set the loopback mode. | loopback { local | remote } | By default, loopback is disabled. |
7. Set the AUG multiplexing mode. | multiplex mode { au-3 | au-4 } | The default setting is AU-4. The command is available only in SDH framing. |
8. Configure the SOH and higher-order path overhead bytes. | flag { c2 path-number c2-value | s1s0 path-number s1s0-value } flag { j0 | j1 path-number } { sdh | sonet } flag-value | By default:
|
9. Set the physical state change suppression interval on the interface. | link-delay seconds | By default, the physical state change suppression interval is 0 seconds. |
10. Set the signal degrade (SD) or signal fail (SF) alarm threshold for the interface. | threshold { sd sdvalue | sf sfvalue } * | By default, the SD threshold is 10e to the power of negative 6 (10e–6) and the SF threshold is 10e to the power of negative 3 (10e–3). |
11. (Optional.) Configure the action to take when an RDI, SD, or SF alarm occurs on the CPOS interface. | alarm-detect { rdi | sd | sf } action link-down | By default, the device does not take any actions on the interface when an RDI, SD, or SF alarm occurs. |
12. (Optional.) Restore the default settings for the CPOS interface. | default | N/A |
13. Bring up the CPOS interface. | undo shutdown | By default, a CPOS interface is up. If no cable is connected to a physical interface, shut down the interface with the shutdown command to prevent problems. |
