Rejecting Incoming RCFs

To reject incoming RCF request frames, perform this task:
Command
Step 1
switch# configuration terminal
switch(config)#
Step 2
switch(config)# interface fc slot/port
switch(config-if)#
Step 3
switch(config-if)# fcdomain rcf-reject vsan
vsan-id
switch(config-if)# no fcdomain rcf-reject vsan
vsan-id

About Autoreconfiguring Merged Fabrics

By default, the autoreconfigure option is disabled. When you join two switches belonging to two
different stable fabrics that have overlapping domains, the following situations can occur:
•
•
The autoreconfigure option takes immediate effect at runtime. You do not need to restart the fcdomain.
If a domain is currently isolated due to domain overlap, and you later enable the autoreconfigure option
on both switches, the fabric continues to be isolated. If you enabled the autoreconfigure option on both
switches before connecting the fabric, a disruptive reconfiguration (RCF) will occur. A disruptive
reconfiguration may affect data traffic. You can nondisruptively reconfigure the fcdomain by changing
the configured domains on the overlapping links and eliminating the domain overlap.

Enabling Autoreconfiguration

To enable automatic reconfiguration in a specific VSAN (or range of VSANs), perform this task:
Command
Step 1
switch# configuration terminal
switch(config)#
Step 2
switch(config)# fcdomain auto-reconfigure vsan
vsan-id
switch(config)# no fcdomain auto-reconfigure vsan
vsan-id
Domain IDs
Domain IDs uniquely identify a switch in a VSAN. A switch may have different domain IDs in different
VSANs. The domain ID is part of the overall FC ID.

If the autoreconfigure option is enabled on both switches, a disruptive reconfiguration phase is
started.
If the autoreconfigure option is disabled on either or both switches, the links between the two
switches become isolated.
