Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)
Enabling the Persistent FC ID Feature
To enable the persistent FC ID feature, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Activates (default) persistency of FC IDs in
the specified VSAN.
switch(config)# fcdomain fcid persistent
vsan vsan-id
Step 2
Disables the FC ID persistency feature in the
specified VSAN.
switch(config)# no fcdomain fcid persistent
vsan vsan-id
Step 3
Persistent FC ID Configuration Guidelines
When the persistent FC ID feature is enabled, you can enter the persistent FC ID submode and add static or
dynamic entries in the FC ID database. By default, all added entries are static. Persistent FC IDs are configured
on a per-VSAN basis.
When manually configuring a persistent FC ID, follow these requirements:
• Ensure that the persistent FC ID feature is enabled in the required VSAN.
• Ensure that the required VSAN is an active VSAN. Persistent FC IDs can only be configured on active
VSANs.
• Verify that the domain part of the FC ID is the same as the runtime domain ID in the required VSAN.
If the software detects a domain mismatch, the command is rejected.
• Verify that the port field of the FC ID is 0 (zero) when configuring an area.
Configuring Persistent FC IDs
To configure persistent FC IDs, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enters FC ID database configuration submode.switch(config)# fcdomain fcid
database
Step 2
Configures a device WWN (33:e8:00:05:30:00:16:df)
with the FC ID 0x070128 in the specified VSAN.
switch(config-fcid-db)# vsan vsan-id
wwn 33:e8:00:05:30:00:16:df fcid fcid
Step 3
To avoid assigning a duplicate FC ID, use the
show fcdomain address-allocation vsan
command to display the FC IDs in use.
