Configuring autoconnect parameters
You can configure the CPE to connect to the ACS periodically, or at a schedule time for configuration or software update. To protect system resources, limit the number of retries that the CPE can make to connect to the ACS.
Configuring the periodic Inform feature
To connect to the ACS periodically for CPE information update:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CWMP view. | cwmp | N/A |
3. Enable the periodic Inform feature. | cwmp cpe inform interval enable | By default, this function is disabled. |
4. (Optional.) Set the Inform interval. | cwmp cpe inform interval interval | By default, the CPE sends an Inform message to start a session every 600 seconds. |
Scheduling a connection initiation
To connect to the ACS for configuration or software update at a scheduled time:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CWMP view. | cwmp | N/A |
3. Schedule a connection initiation. | cwmp cpe inform time time | By default, no connection initiation has been scheduled. |
Setting the maximum number of connection retries
The CPE retries a connection automatically when one of the following events occurs:
The CPE fails to connect to the ACS.
The connection is disconnected before the session on the connection is completed.
The CPE considers a connection attempt as having failed when the close-wait timer expires. This timer starts when the CPE sends an Inform request. If the CPE fails to receive a response before the timer expires, the CPE resends the Inform request.
To set the maximum number of connection retries that the CPE can make:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CWMP view. | cwmp | N/A |
3. Set the maximum number of connection retries. | cwmp cpe connect retry retries | By default, the CPE retries a failed connection until the connection is established. |
Setting the close-wait timer
The close-wait timer specifies the amount of time the connection to the ACS can be idle before it is terminated. The CPE terminates the connection to the ACS if no traffic is transmitted before the timer expires.
The timer also specifies the maximum amount of time the CPE waits for the response to a session request. The CPE determines that its session attempt has failed when the timer expires.
To set the close-wait timer for the CPE:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter CWMP view. | cwmp | N/A |
3. Set the close-wait timer. | cwmp cpe wait timeout seconds | By default, the close-wait timer is 30 seconds. |
