Cisco Nexus 5000 Series - Contiguous Domain ID Assignments; Enabling Contiguous Domain ID Assignments

Contiguous Domain ID Assignments
By default, the contiguous domain assignment is disabled. When a subordinate switch requests the principal
switch for two or more domains and the domains are not contiguous, the following situations can occur:
•
If the contiguous domain assignment is enabled in the principal switch, the principal switch locates
contiguous domains and assigns them to the subordinate switches. If contiguous domains are not available,
the switch software rejects this request.
•
If the contiguous domain assignment is disabled in the principal switch, the principal switch assigns the
available domains to the subordinate switch.
Enabling Contiguous Domain ID Assignments
You can enable contiguous domains in a specific VSAN (or a range of VSANs).
SUMMARY STEPS
1.
configure terminal
2.
fcdomain contiguous-allocation vsan vsan-id - vsan-id
3.
no fcdomain contiguous-allocation vsan vsan-id
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
switch# configure terminal
switch(config)#
Step 1
Enables the contiguous allocation option in the specified
VSAN range.
fcdomain contiguous-allocation vsan vsan-id - vsan-id
Example:
switch(config)# fcdomain contiguous-allocation
vsan 22-30
Step 2
The contiguous-allocation option takes immediate
effect at runtime. You do not need to restart the
fcdomain.
Note
Disables the contiguous allocation option and reverts it to
the factory default in the specified VSAN.
no fcdomain contiguous-allocation vsan vsan-id
Example:
switch(config)# no fcdomain contiguous-allocation
vsan 7
