Management Interface Connection Using Tag-Vlan - Hitachi Compute Blade 2000 User Manual

Management interface connection
using Tag-VLAN
Tag-VLAN (IEEE802.1Q) can be used between MGMT0 or MGMT1 and their
associated switches for connecting to the management interfaces. This allows
various configurations, such as the following:

To enhance security, each server blade can be assigned to a different VLAN,
so that the user of a server blade cannot connect physically to a different server
blade.
 Each module can be assigned to a different virtual local area network (VLAN),
so that the network is clearly segmented by the management target (when
division between ports MGMT0 and MGMT1 is insufficient for this purpose).
A maximum of 19 VLANs can be created, with between 2 and 4000 VLAN IDs.
Either one of ports MGMT0 and MGMT1 must be assigned to each VLAN; both ports
cannot be assigned to the same VLAN.
The Tag-VLAN functionality can be used in conjunction with
management interface

Connect to the management module and switch module through MGMT0, not
via a VLAN. Connect to server blades 0 to 3 through MGMT0 with VLAN IDs 10
to 13, and to server blades 4 to 7 through MGMT1 with VLAN IDs 20 to 23. This
allows separation of the network for specific purposes and distributes the
network load.
VLAN ID 1 and VLAN IDs 4001 to 4094 are used internally
and cannot be used by the customer.
To use Tag-VLAN, the associated switches must also
support IEEE802.1Q VLAN.
