Configuring Domain Attributes - Cisco DS-C9216I-K9 Configuration Manual

Configuring the Domain
Figure 26-2
The behavior for a subordinate switch changes based on the allowed domain ID lists, on the configured
domain ID, and on the domain ID that the principal switch has assigned to the requesting switch:
•
•
•
You must restart the domain if you want to apply the configured domain changes to the runtime domain.
Caution

Configuring Domain Attributes

From this dialog box you can specify a fabric name for fabric logins on the VSAN and set the priority
for the switch used in the principal switch selection process.
Configure the principal attributes for the domain.

Configuration Process Using the "preferred" Option
Switch 7 (subordinate)
Local WWN
20:02:ab:ba:cd:dc:f4:00
Configured domain ID
7 preferred
Runtime domain ID = 7
Configured priority = 128
Runtime priority = 128
Runtime fabric name
20:01:ab:ba:cd:cd:dc:f4
Local WWN
20:03:ab:ba:cd:dc:f4:00
Configured domain ID
7 preferred
Runtime domain ID = 51
Configured priority = 128
Runtime priority = 128
Runtime fabric name
20:01:ab:ba:cd:cd:dc:f4
Switch 7 (subordinate)
When the received domain ID is not within the allowed list, the requested domain ID becomes the
runtime domain ID and all interfaces on that VSAN are isolated.
When the assigned and requested domain IDs are the same, the preferred and static options are not
relevant, and the assigned domain ID becomes the runtime domain ID.
When the assigned and requested domain IDs are different, the following cases apply:
If the configured option is static, the assigned domain ID is discarded, all local interfaces are
–
isolated, and the local switch assigns itself the configured domain ID, which becomes the
runtime domain ID.
If the configured option is preferred, the local switch accepts the domain ID assigned by the
–
principal switch and the assigned domain ID becomes the runtime domain ID.
1. Request configured
domain ID (7).
2. Requested domain
ID assigned,
if available (7).
3. Otherwise, another
available domain
ID assigned (51).
