In the initialization process of any interface on the routing device, a driving module in the routing device generally needs to perform initialization configuration on a PHY chip of the interface according to configuration information corresponding to the type of an optical module of the interface.

An embodiment of the present application provides a chip configuration method, where the method is applied to a driver module in a routing device, and as shown in fig. 1, the method includes the following steps:
s11, when the PHY chip of any interface on the routing device needs to be initialized, if the optical module of the interface is detected to be in the on-position state and no LOS alarm event occurs, judging whether the bus for accessing the optical module has a fault; if yes, go to step S12; when the determination result is no, step S13 is executed.
S12, polling the acquired configuration type information, and executing the following operations when polling to a piece of configuration type information: performing initialization configuration on the PHY chip according to configuration information corresponding to the currently polled configuration type information, and judging whether state information associated with the currently polled configuration type information meets a preset condition or not; if so, determining that the currently polled configuration type information is matched with the type of the optical module, and ending the process; and if not, deleting the configuration content of the PHY chip, and continuing polling the next piece of configuration type information until the current polled configuration type information is matched with the 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 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.
And S13, acquiring the optical module type of the optical module and the corresponding configuration information thereof, and performing initialization configuration on the PHY chip according to the acquired configuration information.
Specifically, in this step S11, the 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 successful, determining that the bus for accessing the optical module has no fault;
and if the access result is access failure, determining that the bus for accessing the optical module has a fault.
It should be noted that, a specific access flow of the driver module accessing the optical module register of the optical module is the prior art, and is not described in detail herein.
Specifically, in step S12, the configuration type information may be obtained by the driver module when the PHY chip needs to be initially configured; the driver module may acquire the information when determining that the bus for accessing the optical module has failed.
In addition, in the step S12, in a case that the status information includes the interface status of the interface, when determining whether the status information associated with the currently polled configuration type information satisfies the preset condition, the driving module may determine whether the interface status of the interface is an UP status.
In a case that the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module, when determining whether the state information associated with the currently polled configuration type information satisfies a preset condition, the driving module may determine whether a total number value of link states in the link states of the plurality of Serdes links that are UP states is consistent with a total number value of Serdes links corresponding to the currently polled configuration mode.
The chip configuration method is described in detail with reference to specific embodiments
Example one
It is assumed that when a PHY chip 121 of an interface (e.g., interface 12) on a routing device 1 needs to be initialized and configured, a driving module 11 in a routing device (e.g., routing device 1) in a network detects that an optical module 122 of the interface 1 is in an in-place state and no LOS alarm event occurs, and at this time, the driving module 11 accesses an 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, and in this case, the driving module 11 executes an existing configuration process, that is, acquires an optical module type of the optical module 122 and configuration information corresponding to the optical module type, and performs 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 a Small Form-factor Pluggable transceiver (SFP), a Small Form-factor Pluggable transceiver (QSFP), a C-package Pluggable transceiver (CFP), or the like. For example, the optical module type of the optical module 122 is 100G BASE-LR 4.
If the access result is an access failure, the driving module 11 determines that the optical module 122 fails, in which case the driving module 11 starts polling the acquired plurality of optical module types supported by the interface 12, and performs the following operations each time when polling reaches to one optical module type: according to the configuration information corresponding to the type of the optical module polled currently, performing initialization configuration on the PHY chip, and judging whether the interface state of the interface 12 is an UP state; if so, determining that the currently polled optical module type is matched with the optical module type of the optical module 122, and ending the process; if not, deleting the configuration content of the PHY chip, and continuing polling the next optical module type until it is determined that the currently polled optical module type matches the optical module type of the optical module 122.
For example, assuming that the optical module type of the optical module 12 is 100G BASE-LR4, assuming that the interface 1 supports 3 optical module types, assuming that the drive module 11 polls the 2 nd optical module type, after performing initialization configuration on the PHY chip 11 according to configuration information corresponding to the 2 nd optical module type, it is found that the 2 nd optical module type is consistent with (i.e., matched with) the optical module type of the optical module 12, at this time, it indicates that the interface 1 is in an UP state, and may normally transmit traffic, and the drive module 11 does not poll the 3 rd optical module type any more.
Example two
Still taking the routing device 1 in the first embodiment as an example, when the driving module 11 needs to perform initialization configuration on the PHY chip 121 of the interface 12 on the routing device 1, it is detected that the optical module 122 of the interface 1 is in an in-place state and no LOS alarm event occurs, at this time, the driving module 11 accesses an 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, and in this case, the driving module 11 executes an existing configuration process, that is, acquires an optical module type of the optical module 122 and configuration information corresponding to the optical module type, and performs 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 the optical module type mentioned in the first embodiment.
If the access result is an access failure, the driving module 11 determines that the optical module 122 has a failure, in this case, the driving module 11 starts to poll the acquired plurality of configuration modes supported by the PHY chip 11, and performs the following operations each time when polling reaches one configuration mode: according to the configuration information corresponding to the currently polled configuration mode, performing initialization configuration on the PHY chip, and judging whether the total number value of links with the UP state in the link states of the plurality of Serdes links between the PHY chip 11 and the optical module 12 is consistent with the total number value of Serdes links corresponding to the currently polled configuration mode; if so, determining that the currently polled configuration mode is matched with the optical module type of the optical module 122, and ending the process; if not, deleting the configuration content of the PHY chip, and continuing polling the next optical module type until it is determined that the currently polled configuration mode matches 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, where the configuration modes are both additional unit interface modes, when the driving module 11 polls the CAUI-4 mode, after initializing and configuring the PHY chip 11 according to configuration information corresponding to the CAUI-4 mode, it is found that the total number value of the link states of the Serdes link between the PHY chip 11 and the optical module 12, which is an UP state, is 4, and the total number value (i.e., 4) of the Serdes link corresponding to the CAUI-4 mode is consistent, at this time, it is described that the CAUI-4 mode matches the optical module type (e.g., 100G BASE-LR4) of the optical module 12, that is, the interface 1 is in the UP state, and can normally transmit traffic, and does not continue polling.
It can be seen from the foregoing technical solutions that, in the embodiment of the present application, for a driving module in a routing device, when a PHY chip of any interface on the routing device needs to be initialized and configured, once it is detected that an optical module of the interface is in an in-place state and a LOS alarm event does not occur, the driving module may first determine whether a bus for accessing the optical module fails.
Then, in the case that the determination result is yes, polling the acquired multiple pieces of configuration type information, and executing the following operations every time one piece of configuration type information is polled: performing initialization configuration on the PHY chip according to configuration information corresponding to the currently polled configuration type information, and judging whether state information associated with the currently polled configuration type information meets a preset condition or not; if so, determining that the currently polled configuration type information is matched with the type of the optical module, namely that the interface is in an UP state, and ending the process; and if not, deleting the configuration content of the PHY chip, and continuing polling the next piece of configuration type information until the current polled configuration type information is matched with the type of the optical module.
Here, when the plurality of configuration type information includes 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.
Therefore, through the configuration process, 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.
Based on the same inventive concept, the present application further provides a chip configuration apparatus, where the apparatus is applied to a driving module in a routing device, and a schematic structural diagram of the apparatus is shown in fig. 2, and specifically includes:

wherein the state information includes an interface state of the interface when the plurality of configuration type information includes a plurality of optical module types supported by the interface; when the plurality of pieces of configuration type information include 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 determining unit 21 is specifically configured to determine whether a bus for accessing the optical module fails by:
accessing an optical module register of the optical module;
if the access result is successful, determining that the bus for accessing the optical module has no fault;
and if the access result is access failure, determining that the bus for accessing the optical module has a fault.
Preferably, the apparatus further comprises:
a second configuration unit (not shown in fig. 2), configured to, if the determination result of the determining unit 21 is negative, acquire an optical module type of the optical module and configuration information corresponding to the optical module type, and perform initialization configuration on the PHY chip according to the acquired configuration information.
Preferably, when the state information includes the 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.
Preferably, when the state information includes link states of a plurality of Serdes links between the PHY chip and the optical module, the first configuration unit 22 is specifically configured to determine whether a total number value of the link states of the plurality of Serdes links that are in an UP state is consistent with a total number value of Serdes links corresponding to a currently polled configuration mode.
It can be seen from the foregoing technical solutions that, in the embodiment of the present application, for a driving module in a routing device, when a PHY chip of any interface on the routing device needs to be initialized and configured, once it is detected that an optical module of the interface is in an in-place state and a LOS alarm event does not occur, the driving module may first determine whether a bus for accessing the optical module fails.
