Embodiment two
See Fig. 3, based on embodiment one, embodiments provide a kind of method that PXE starts, be described in more detail for starting PXE, the method comprises the following steps:
The port arrangement of oneself is aggregation port by step 201, switch.
In the present embodiment, before carrying out static LACP negotiation with BMC, the port arrangement of oneself is first aggregation port by switch, such as, in Fig. 1, forms aggregation port after the port 3 of switch and port 4 being polymerized.
After step 202, BMC detect processor reset, at least two corresponding for the MII of oneself network interfaces are configured to Bond pattern, then carry out static LACP negotiation with switch, after setting up the first link, open the first aggregation port of switch.
In the present embodiment, as shown in Figure 1, after BMC detects processor reset, network interface 3 and network interface 4 are set to Bond pattern, such as, under Linux environment, Bond mode can be set to 4, thus at least two of a BMC network interface can be bound a network interface use, the NCSI of the corresponding network interface card of network interface of this binding, when network interface 3 breaks down, network interface 4 can work on, available to ensure that the network interface of this binding continues.The first aggregation port opening switch refers to and allows the first aggregation port of switch be in selected state, and namely the port 3 of switch and the aggregation port of port 4 formation are in normal condition, can forward user's message.
Step 203, processor pass through intelligent platform management interface (Intelligent PlatformManagement Interface, IPMI) passage to BMC transmission lag message.
In the present embodiment, this delay message is specifically as follows starting device list message, and starting device list message comprises PXE and starts mark, and BMC starts mark according to PXE and knows that processor needs to carry out PXE startup, and then the time that judgement is carried out needed for PXE startup.
