| Chapter 3 Configuration |
Operation information for MPNET on each interface is defined. This configuration cannot be omitted.
The following configuration samples are provided in this file. Copy the line to be used from the sample to configure the configuration for the communication type.
The form of the entry is shown below.
Each parameter is explained as follows.
This indicates the interface name of the MPNET.
See the section "3.2 /etc/opt/FJSVmpnet/conf/config" to specify the interface name.
Unique values must be specified in the same configuration.
This indicates MAC address.
The specified MAC address is used to take over in the communication path that are composed of one interface.
To have the MAC address taken over in the communication path, specify "-" in the global MAC address.
To replace the MAC address with other values for takeover, specify your MAC address with the 12 digit number.
- When the ATM card is used, "-" (global MAC address) cannot be specified for the MAC address. Please specify a local MAC address, and apply the following regulations.
The MAC address of the first logical device (li0 and li32, etc.) becomes base point, and the MAC address of the next logical device becomes the MAC address plus 1 (hexadecimal number).
For instance, when the MAC address of li0 is "020000000000", the MAC address of li1 is "020000000001", and the MAC address of li16 becomes "020000000010".
The Multipath function should set the MAC address according to these regulations. Refer to "Example of ATM connection and environment configuration."- In the cluster system, "-" (global MAC address) cannot be used when SNA or FNA protocol is used for the high-layer protocol. The MAC address value must be specified.
Function mode
The following values can be specified.
- 0 : Use Multipath method.
- 1 : Use Multilink Ethernet method.
If any other value is specified, the mode cannot be activated.
Multilink Ethernet data distribution method
This parameter is valid if 1 (Multilink Ethernet method) is specified in the func-mode parameter. If 0 (Multipath method) is specified, specify 0 for this parameter.
The following values can be specified.
- 0 : Use the MAC address distribution method.
- 1 : Use the round-robin distribution method.
- 2 : Use the destination IP address distribution method
- 3 : Use the destination/source IP address distribution method
If any other value is specified, the Multilink Ethernet data distribution method cannot be activated.
This indicates the cluster configuration.
Choose one of the following for the target interface:
Specify "none" for no cluster target.
Specify space (blank) for the cluster target.
When using ATM, the MPNET interface which takes over by the cluster, and the MPNET interface which is not so cannot be intermingled.
Refer to "Chapter 7 Administration on a Cluster System" for the environmental configuration method of cluster system.
The configuration example is shown in the following:
- Environmental configuration example of Ethernet connection or FDDI connection
- Example of ATM connection and environment configuration
The example of setting the MAC address is described based on the interface of "Example of ATM connection and environmental configuration" described to the /etc/opt/FJSVmpnet/conf/config file.
- Interface mpnet0 (Logical device name:li0/li32)
- Interface mpnet1 (Logical device name:li1/li33)
- Interface mpnet2 (Logical device name:li16/li48)
When the MAC address which mpnet0 uses is set as "020000000000", the MAC address of mpnet1 adds 1 (hexadecimal number) from the MAC address of mpnet0, and becomes "020000000001".
Similarly, the MAC address of mpnet2 adds 0x10 from The MAC address of mpnet0, and becomes "020000000010".
The configuration example is shown in the following:
