To statically build a fabric, you must manually configure a domain ID for each switch.
To dynamically build a fabric, you can configure a desired domain ID for a switch, but the domain ID
assigned to the switch might not be the desired one.
The configured domain ID can be static type or preferred type.
• In a statically built fabric, the two types make no difference.
• In a dynamically built fabric, when a non-principal switch fails to obtain the desired domain ID from
the principal switch, the following rules apply:
{
If the desired domain ID is of the preferred type, the non-principal switch can use another
domain ID assigned by the principal switch.
{
If the desired domain ID is of the static type, the non-principal switch will isolate the upstream
link and refuse other domain IDs assigned by the principal switch.
H3C recommends that you configure domain IDs of the same type to all switches in a VSAN.
To configure a domain ID for a switch:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VSAN view. vsan vsan-id N/A
3. Configure a domain ID for
the switch. domain-id domain-id { preferred |
static } By default, the domain ID of a switch is
0 and is of the preferred type.
Binding the WWN of an N_Port to an FC address
If you bind the WWN of an N_Port to an FC address, the switch assigns the bound FC address to the
N_Port when the N_Port requests an FC address.
The WWN of an N_Port can be bound to only one FC address, and vice versa.
The N_Port here indicates an N_Port on a node or an NP_Port on an NPV switch.
To bind the WWN of an N_Port to an FC address:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VSAN view. vsan vsan-id N/A
3. Bind the WWN of an
N_Port to an FC address.
wwn wwn-value area-port-id
area-port-id-value
By default, no binding is
configured.
If the N_Port has been assigned
another FC address or the FC
address has been assigned to
another N_Port, the binding is
not allowed.
