From the viewpoint of BS2000 devices, the ZASLAN and LOCLAN are devices which are used for the LAN connection to the external physical network or for internal communication in the Server Unit. They can be created in the SE Manager (see section "Managing LAN devices") and must, in the case of VM2000, then be assigned to the BS2000 VM concerned.
BS2000 ZASLAN
In the case of a ZASLAN connection, BS2000 uses a LAN interface of its own (Ethernet controller) independently of other LAN interfaces. Only via such a connection does BS2000 obtain a direct view of the physical network.
In VM2000 mode a LAN interface can be used jointly by all connected BS2000 guest systems. To permit this, a separate ZASLAN connection is configured for each BS2000 VM. The associated devices are connected to their particular VM (using the /ADD-VM-DEVICES command).
The ZASLAN interfaces are displayed or modified in the SE Manager using Devices -> [<se server> (SE<model>) ->] <unit> (SU<model>) on the LAN tab.
All PCI ports can be used for the ZASLAN connections.
LOCLAN
The local LAN is a network implemented by software in the Linux-based basic system concerned (X2000/M2000/HNC). The local LAN connections are consequently not included in the figure illustrating the LAN structure (see Figure 2 in section "Networks"). The connection of BS2000 to the local LAN is implemented on an SU x86 system with connections implemented by software (MANLO: Management Network LOCLAN), and on an SU /390 by FC connections between SU /390 and MU (MANLO) or HNC.
The following addresses are preconfigured for BS2000 and the basic system (X2000/M2000):
System | IP address |
Basic system | 192.168.138.12 |
BS2000 (Native or monitor system) | 192.168.138.21 |
BS2000 guest systems on other VMs | 192.168.138.22 etc. |
A second MU (in case of SU /390) is automatically assigned the addresses 192.168.139.x. If address conflicts occur, Customer Support can configure other address ranges.
