each partition.
ports in the relevant partition must have IP addresses. (Assign
IP addresses to the ports used for actual operation.)
*1 The default IP address (172.30.0.[partition number + 2]) is assigned during installation of SVS. The default
IP address can be used unless it is in conflict with the one in the other subnet.
Remarks
- The NIC in PCH on the Home SB is used as the NIC of the partition for internal LAN. The network device
name is not defined uniquely. The NIC in PCH on the Home SB is searched by using the bus number,
device number, and function number assigned to NIC.
- Even if the Home SB is switched by Reserved SB function, Internal LAN is kept communicating. MMB
writes over the MAC address of the NIC in PCH on the Home SB and keeps the same MAC address as
that before the SB was switched.
For this MAC address, a unique value is assigned to each partition and managed as system FRU
information so that it is unique per cabinet.
- Only “AutoNego” is supported as setting of GbE port speed in IOU_10GbE.
1.3 Management LAN
This section describes the configuration of the management LAN for the PRIMEQUEST 2000 series.
1.3.1 Overview of the management LAN
The MMB has two GbE LAN ports (USER ports) dedicated to the management LAN.
The partition side can use the LAN port on the IOU as a management LAN port. The PCL communications/
operations management server is connected to the MMB USER port through an external switch.
IP addresses of the management LAN (MMB)
Each MMB has one physical IP address for the management interface of the PRIMEQUEST 2000 series
server. In addition to that, the primary MMB shares a common virtual IP address in the system. You can set
these IP addresses from the MMB Web-UI or CLI.
Remarks
Virtual LAN interfaces are used for the management LAN interfaces. The physical LAN interfaces are used
only for recognizing the respective MMBs.
The physical LAN interface of each MMB makes redundant the two User ports located in that MMB, using the
interface redundancy function, to create a single LAN interface.
Virtual LAN interfaces handle the common virtual IP address shared between the two redundant MMBs. The
Virtual LAN interfaces share the physical LAN interfaces, which are ports on the two MMBs. The ports are
treated as valid channels on the active MMB. Any switching of the active MMB causes switching of the
corresponding connections to Virtual LAN channels.
The following shows a management LAN configuration diagram. The IP addresses are examples. The
addresses depend on the settings.
