The following shows the procedure for changing configuration information for Fast switching mode:

1. Inactivate the concerned virtual interface using the "stphanet" command. For information, see "7.3 stphanet Command".
2. Change the configuration information.
3. After changing the configuration information, activate the concerned virtual interface using the "strhanet" command. For information, see "7.2 strhanet Command".

The procedure to change the information of a monitoring function is as follows:

1. Change the information of a monitoring function using a "hanetparam" command. See "7.6 hanetparam Command" for the detail. In this case, it is not necessary to reactivate a virtual interface. The information becomes valid immediately after changed.
