Command connectivity options

This topic describes the command connectivity options, which are a set of parameters that relate to the ASU connection on the IMM.

The connectivity options might be required when you connect the ASU to a local IMM. When you attempt to connect the ASU to a local IMM and none of the connectivity parameters are specified, the ASU attempts to connect to the IMM by using the default LAN over USB interface settings.

The default settings include user ID, password, and host. The values for these settings are defined by the IMM hardware. If none of these settings are specified on a local connection and the default LAN over USB interface settings fail, the ASU attempts to connect over the KCS interface. The KCS interface does not require any of these parameters.

To connect the ASU remotely to the IMM, also referred to as out-of-band way, the host, "user, and password must all be specified. Beginning with version 9.41, ASU will not provide a default user and password in out-of-band way.

ASU also supports connecting the ASU remotely to the IMM with the mtsn parameter, which is a string composed with machine type and model and serial number if the server running ASU and the IMM are in one LAN.

When mtsn is specified, the net parameter is optional. The net parameter is used to specify the network interface through which the ASU sends messages to a LAN.

If the mtsn and net parameters are specified, the ASU tries to search the target IMM whose machine type, model, and serial number are equal to the mtsn parameter in the LAN the network interface specified by the net parameter is in. If the mtsn parameter is specified and the net parameter is not specified, the ASU will try to search the target IMM whose machine type, model, and serial number are equal to the mtsn parameter in the LAN to which the server running ASU is linked.

If the server running ASU has more than one network interface that is linked to different LANs, ASU tries to search the target IMM in the LANs one by one. After the target IMM is found, ASU obtains the host IP address from the target IMM and tries to use it to connect to the IMM.

In the Linux version of ASU, the net parameter should be the name of the network interface, such as eth0, eth1, lo, and so on.

In the Windows version of ASU, the net parameter should be an integer that indicates the index of the network interface. You can use the command arp -a to get all of the indexes of the network interfaces that exist. For example, the information in the following table may be shown when you use the command: arp -a:

Table 56 shows two interfaces whose indexes are 0xc and 0xf and whose IP addresses are 9.111.23.166 and 9.111.30.161, respectively. The indexes shown in Table 56 are in hexadecimal format. Before being input to ASU as the --net parameter, they should be transferred to decimal integers.

In the following example, the two decimal integers should be 12(0xc) and 15(0xf). If you want ASU to scan IMMs in the LAN to which the network interface 12 is linked, add --net 12 to the list of parameters for the ASU command.

Any local or remote LAN over USB connection requires authentication. The default authentication parameters are the default user ID and password that come configured with each IMM. For the default authentication settings, see the documentation that comes with the server or optional devices.
