The following shows an example of outputting a message when a command is executed, change the MTU length, deleting the concerned information from the ARP table, and checking the communication (executes the ping command).
Note that three-digit numbers placed on the left end of this example need not be placed in the actual script file because they just indicate line numbers for the purpose of explanation.
* An example of setting operated only in IPv4.

The following explains this setting example. In the explanation, [xxx] represents a line number in this setting example.
[031-071]: Describe the processing of activating the interface.
[042-050]: Outputs a message that a command is executed and sets the interface information (MAC address) depending on the interface type to be processed before the interface is activated.
[055-064]: Outputs a message for executing command. Then, changes the length of MTU after activating the interface. Finally, it deletes the corresponding ARP information and checks for a communication.
[072-099]: Describe the processing of inactivating the interface.
[083-084]: Outputs a message that a command is executed before the interface is inactivated.
[090-092]: Outputs a message that a command is executed after the interface is inactivated.
