The user utilizes the BMC to monitor the physical characteristics of the server, such as temperature, voltage, fan operating status, power supply, and chassis intrusion of the components.
IPv6 is an abbreviation for "Internet Protocol Version 6", also known as next generation Internet Protocol, which is a new IP Protocol designed by IETF (Internet Engineering Task Force) group to replace the current IPv4 Protocol.
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and the detailed description.
Fig. 1 is a flowchart illustrating a method for testing the functionality of the BMC IPV6 based on a virtual machine according to an exemplary embodiment, where the method includes the following steps:
SS1, configuring virtual machine system environment;
SS2, configuring a virtual machine IPV6, and configuring a virtual machine to be bridged with a local machine;

In an embodiment, for the technical solution shown in fig. 1, as shown in fig. 3, the step SS2 of configuring the virtual machine IPV6 specifically includes the following steps:
SS201, establishing a scope through DHCP;

performing a BMC IPV6 address lease test;
performing a BMC IPV6 connectivity test;
a BMC IPV6 packet loss test is performed.
It should be noted that, the IPV6 lease refers to the lease time of the IP address, and when the lease time reaches a set value, the IP address must be released and leased again.
The IPV6 address lease, IPV6 connectivity test, and IPV6 packet loss test are very important parts of the IPV6 function, and need to be tested to ensure that the IPV6 functions normally.
In one embodiment, for the solution shown in fig. 1, the BMC IPV6 address lease test of one of the BMC IPV6 function tests executed in step SS3 includes the following steps, and is shown in fig. 4:

SS312, configuring the new IP as IP2, binding mac1 with IP2, and configuring an address lease of IP 2;
and the SS313 confirms whether the IP of the BMC is changed into the IP2 after the address lease period.
It should be specially noted that after step SS2 is completed, no operation is performed on the BMC port, including but not limited to restarting the BMC, switching the dhcp, stateful, and plugging and unplugging the BMC network.
It should be noted that IP1 is assigned randomly for DHCP, and IP2 is mandatory for DHCP server.
In one embodiment, for the solution shown in fig. 1, the BMC IPV6 connectivity test of step SS3, which is performed as one of the BMC IPV6 functional tests, includes the following steps, and is shown in fig. 5:

In an embodiment, for the technical solution shown in fig. 1, the performing of the BMC IPV6 packet loss test, which is one of the BMC IPV6 function tests in step SS3, includes the following steps, and is shown in fig. 6:
SS331, a data network IP and network pressure, ping a node to be tested BMC IP for a plurality of times, and detecting that the packet loss rate cannot be higher than a set threshold value;
SS332, reboot tested nodes, and BMC IP ping the tested nodes for a plurality of times, and packet loss can not occur;
SS333, power cycle tested node, ping tested node BMC IP several times, can not appear losing the packet.
It should be specially noted that, the set threshold of the packet loss rate is usually 0.5%; the "number of times" is usually set to 1000 times.
It should be noted that ping belongs to a communication protocol and is part of the TCP/IP protocol. The 'ping' command can be used for checking whether the network is connected or not, and can well help us to analyze and judge network faults.
Finally, it is to be specially noted that the BMC IPV6 address lease test, the BMC IPV6 connectivity test, and the BMC IPV6 packet loss test may be executed individually or sequentially, and when the tests are executed sequentially, if the IP address obtained by the BMC DHCP is finished after the lease, the IP address can be normally obtained; after the BMC is restarted, the dedicate NIC can restore the connection within the preset time; and no packet loss occurs in the processes of pressurizing and restarting the node by the BMC, so that the function test result of the BMC IPV6 is good.
