Naming Scheme; Switch Name; Naming/Addressing Within A Stack - Fujitsu PRIMERGY BX900 User Manual

6.7

Naming Scheme

The naming scheme for the stack member is described in this section. It will provide an easy way for
user to identify and manipulate the specific switch module, and port of a switch module.
The MMB has to provide the following information via ISMIC to be read by Switch:
1. Rack Name (read only): reserved for future use, will be empty.
2. Enclosure Name (read only): MMB will retrieve the Serial No. from the FRU data of the enclosure
and make it as the Enclosure Name. (This name MUST be unique.)
3. Bay Number (1-8) (read only): Static bay number is assigned by MMB via ISMIC.
4. SWM User Assigned Name (read/write): This field is just used as the hostname for the switch and
might be used as DNS name so that this name can be used to access the Switch from Web UI.
6.7.1

Switch Name

The name of Switch is using Ethernet Connection Blade Module's User-Assigned Name as its name.
This default name may be changed by either MMB or Switch through the available interfaces (CLI/Web
UI) and is written to the ISMIC memory. During the Ethernet Connection Blade Module booting stage, it
always reads and uses this name as the hostname and will be used as DNS name. (Notes: DNS name is
only valid if the DNS client is support.)
If there is no name was specified by MMB, it will use the stored name from the configuration file as its
hostname.
6.7.2

Naming/Addressing within a Stack

MMB has to prepare the necessary naming information as the Ethernet Connection Blade Module is
plugged into the chassis. After Ethernet Connection Blade Module is powered on by Management Blade
(MMB), it will read those information via ISMIC.
The MMB will use <Rack Name>-<Enclosure Name>-CB<Bay Number> (or <Enclosure
Name>-CB<Bay Number> if <Rack Name> is not defined) as the identifier for the Ethernet Connection
Blade Module and put this identifier on the field of SWM User Assigned Name of ISMIC to Ethernet
Connection Blade Module. Ethernet Connection Blade Module will use this name "<Rack
Name>-<Enclosure Name>-CB<Bay Number>/<Slot ID>/<Port>" to manipulate the ports of that
Ethernet Connection Blade Module. <Slot ID>/<Port> is used to identify physical ports or logical ports
(port-channel). For example, the first port-channel on enclosure 1 and bay 1 will be represented as
"Rack1-Encl1-CB1/1/1".
