Next, embodiments of the present application will be described in detail.
The embodiment of the application provides a chip configuration method, which is applied to a driving module in a routing device, as shown in fig. 1, and the method comprises the following steps:
s11, when the PHY chip of any interface on the routing equipment needs to be initialized and configured, if the optical module of the interface is detected to be in an in-place state and no LOS alarm event occurs, judging whether a bus for accessing the optical module fails or not; when the judgment result is yes, executing a step S12; if the determination result is negative, step S13 is executed.
S12, polling the acquired pieces of configuration type information, and executing the following operations when one piece of configuration type information is polled: initializing and configuring the PHY chip according to configuration information corresponding to the configuration type information which is currently polled, and judging whether state information associated with the configuration type information which is currently polled meets preset conditions or not; when the judgment result is yes, determining that the currently polled configuration type information is matched with the optical module type of the optical module, and ending the flow; and deleting the configuration content of the PHY chip when the judgment result is negative, and continuing to poll the next piece of configuration type information until the currently polled configuration type information is determined to be matched with the optical module type of the optical module.
In this step, when the plurality of pieces of configuration type information include a plurality of optical module types supported by the interface, the above-mentioned state information includes an interface state of the interface.
When the plurality of configuration type information includes a plurality of configuration modes supported by the PHY chip, the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module.
S13, acquiring the type of the optical module and the corresponding configuration information of the optical module, and initializing and configuring the PHY chip according to the acquired configuration information.
Specifically, in this step S11, the above-described driving module may determine whether the bus for accessing the optical module has failed by:
accessing an optical module register of an optical module;
if the access result is that the access is successful, determining that the bus for accessing the optical module is not failed;
if the access result is that the access fails, determining that the bus for accessing the optical module fails.
It should be noted that, a specific access procedure of the driving module to access the optical module register of the optical module is a prior art, and will not be described in detail herein.
Specifically, in the step S12, the pieces of configuration type information may be acquired by the driving module when the PHY chip needs to be configured in an initializing manner; the driving module may be acquired when it is determined that the bus for accessing the optical module is faulty.
In addition, in the step S12, in a case where the state information includes an interface state of the interface, the driving module may determine whether the interface state of the interface is an UP state when determining whether the state information associated with the currently polled configuration type information satisfies a preset condition.
In the case that the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module, the driving module may determine whether a total number of link states of the plurality of Serdes links, which are UP states, is identical to a total number of Serdes links corresponding to the currently polled configuration mode when determining whether the state information associated with the currently polled configuration type information satisfies a preset condition.
The above chip configuration method will be described in detail with reference to the following embodiments
Example 1
Assuming that the driver module 11 in a certain routing device (e.g., the routing device 1) in a certain network needs to perform initialization configuration on the PHY chip 121 of a certain interface (e.g., the interface 12) on the routing device 1, the driver module 11 accesses the optical module register of the optical module 122 when detecting that the optical module 122 of the interface 12 is in a bit state and no LOS alarm event occurs.
If the access result is that the access is successful, the driving module 11 determines that the optical module 122 has not failed, in which case, the driving module 11 performs the existing configuration procedure, that is, acquires the optical module type of the optical module 122 and the configuration information corresponding thereto, and performs the initialization configuration on the PHY chip 121 according to the acquired configuration information.
Here, the optical module type of the optical module 122 may be an optical module type packaged according to a protocol such as Small Form-factor pluggable transceiver (SFP), small Form-factor pluggable transceiver (Quad Small Form-factor Pluggable transceiver, QSFP), and C-Form-factor pluggable transceiver (C Form-factor Pluggable transceiver, CFP). For example, the optical module 122 has an optical module type of 100G BASE-LR4 or the like.
If the access result is that the access fails, the driving module 11 determines that the optical module 122 fails, in which case the driving module 11 starts to poll the acquired plurality of optical module types supported by the interface 12, and performs the following operations when one optical module type is polled: initializing and configuring the PHY chip according to configuration information corresponding to the type of the currently polled optical module, and judging whether the interface state of the interface 12 is an UP state or not; when the judgment result is yes, determining that the type of the optical module currently polled is matched with the type of the optical module 122, and ending the flow; and deleting the configuration content of the PHY chip when the judgment result is negative, and continuing to poll the next optical module type until the currently polled optical module type is determined to be matched with the optical module type of the optical module 122.
For example, assuming that the optical module type of the optical module 122 is 100G BASE-LR4, assuming that the interface 12 supports 3 optical module types, and assuming that when the driving module 11 polls the 2 nd optical module type, after initializing the PHY chip 121 according to the configuration information corresponding to the 2 nd optical module type, it is found that the 2 nd optical module type is consistent (i.e. matched) with the optical module type of the optical module 122, at this time, it is indicated that the interface 12 is in an UP state, and can normally transmit traffic, and the driving module 11 does not continuously poll the 3 rd optical module type any more.
Example two
Taking the routing device 1 in the first embodiment as an example, when the driver module 11 needs to perform the initialization configuration on the PHY chip 121 of the interface 12 on the routing device 1, it detects that the optical module 122 of the interface 12 is in a bit state and no LOS alarm event occurs, and at this time, the driver module 11 accesses the optical module register of the optical module 122.
If the access result is that the access is successful, the driving module 11 determines that the optical module 122 has not failed, in which case, the driving module 11 performs the existing configuration procedure, that is, acquires the optical module type of the optical module 122 and the configuration information corresponding thereto, and performs the initialization configuration on the PHY chip 121 according to the acquired configuration information.
Here, the optical module type of the optical module 122 may be the same as that mentioned in the above-described embodiment one.
If the access result is an access failure, the driving module 11 determines that the optical module 122 is malfunctioning, in which case the driving module 11 starts to poll the acquired plurality of configuration modes supported by the PHY chip 121, and performs the following operations each time one configuration mode is polled: initializing and configuring the PHY chip according to configuration information corresponding to the currently polled configuration mode, and judging whether the total number value of the link states of the plurality of Serdes links between the PHY chip 121 and the optical module 122, which is the UP state, is consistent with the total number value of the Serdes links corresponding to the currently polled configuration mode; when the judgment result is yes, determining that the currently polled configuration mode is matched with the optical module type of the optical module 122, and ending the flow; and if the judgment result is negative, deleting the configuration content of the PHY chip 121, and continuing to poll the next optical module type until the currently polled configuration mode is determined to be matched with the optical module type of the optical module 122.
For example, assuming that the configuration modes supported by the PHY chip include a CAUI-4 mode and a CAUI-10 mode, these configuration modes are both additional unit interface modes, and assuming that when the driver module 11 polls the CAUI-4 mode, after initializing the PHY chip 121 according to configuration information corresponding to the CAUI-4 mode, it is found that the total number of link states of the Serdes links between the PHY chip 121 and the optical module 122 is 4, and the total number of the Serdes links corresponding to the CAUI-4 mode is identical (i.e., 4), this indicates that the CAUI-4 mode matches with the optical module type (e.g., 100G BASE-LR 4) of the optical module 122, i.e., the interface 12 is in the UP state, and traffic can be normally transmitted without further polling.
As can be seen from the above technical solutions, in the embodiments of the present application, when a driver module in a routing device needs to perform initialization configuration on a PHY chip of any interface on the routing device, once an optical module of the interface is detected to be in an in-place state and no LOS alarm event occurs, the driver module will first determine whether a bus for accessing the optical module fails.
Then, under the condition that the judgment result is yes, the acquired pieces of configuration type information are polled, and when one piece of configuration type information is polled, the following operation is executed: initializing and configuring the PHY chip according to configuration information corresponding to the configuration type information which is currently polled, and judging whether state information associated with the configuration type information which is currently polled meets preset conditions or not; when the judgment result is yes, determining that the currently polled configuration type information is matched with the optical module type of the optical module, namely, the interface is in an UP state, and ending the flow; and deleting the configuration content of the PHY chip when the judgment result is negative, and continuing to poll the next piece of configuration type information until the currently polled configuration type information is determined to be matched with the optical module type of the optical module.
Here, when the plurality of pieces of configuration type information include a plurality of optical module types supported by the interface, the state information includes an interface state of the interface; when the plurality of pieces of configuration type information includes a plurality of configuration modes supported by the PHY chip, the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module.
Therefore, through the configuration flow, the interface can be ensured to be in an UP state, so that the service flow can be normally transmitted, and the network communication quality is improved.

wherein, when the plurality of pieces of configuration type information include a plurality of optical module types supported by the interface, the state information includes an interface state of the interface; when the plurality of configuration type information includes a plurality of configuration modes supported by the PHY chip, the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module.
Preferably, the judging unit 21 is specifically configured to judge whether a bus for accessing the optical module is faulty by:
accessing an optical module register of the optical module;

Preferably, the apparatus further comprises:

Preferably, when the state information includes an interface state of the interface, the first configuration unit 22 is specifically configured to determine whether the interface state of the interface is an UP state.

As can be seen from the above technical solutions, in the embodiments of the present application, when a driver module in a routing device needs to perform initialization configuration on a PHY chip of any interface on the routing device, once an optical module of the interface is detected to be in an in-place state and no LOS alarm event occurs, the driver module will first determine whether a bus for accessing the optical module fails.
