Configuring Fabric Names
To set the fabric name value for a disabled fcdomain, follow these steps:
About Incoming RCFs
You can configure the
rcf-reject
option on a per-interface, per-VSAN basis. By default, the
rcf-reject
option is disabled (that is, RCF request frames are not automatically rejected).
The
rcf-reject
option takes immediate effect takes effect immediately. No fcdomain restart is required.
Rejecting Incoming RCFs
To reject incoming RCF request frames, follow these steps:
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 cases apply:
•
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.
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 getting rid of the domain overlap.
Command
Purpose
Step 1
switch#
config t
switch(config)#
Enters configuration mode.
Step 2
switch(config)#
fcdomain fabric-name
20:1:ac:16:5e:0:21:01 vsan 3
Assigns the configured fabric name value in VSAN 3.
switch(config)#
no fcdomain fabric-name
20:1:ac:16:5e:0:21:01 vsan 3010
Changes the fabric name value to the factory default
(20:01:00:05:30:00:28:df) in VSAN 3010.
Command
Purpose
Step 1
switch#
config t
switch(config)#
Enters configuration mode.
Step 2
switch(config)#
interface fc1/1
switch(config-if)#
Configures the specified interface.
Step 3
switch(config-if)#
fcdomain rcf-reject vsan 1
Enables the RCF filter on the specified
interface in VSAN 1.
switch(config-if)#
no fcdomain rcf-reject vsan 1
Disables (default) the RCF filter on the
specified interface in VSAN 1.
