Forcing Fabric Binding Activation
Note After activation, any already logged in switch that violates the current active database will be logged out, and
all switches that were previously denied login because of fabric binding restrictions are reinitialized.
To activate the fabric binding feature, follow these steps:
Procedure
Step 1
switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2 switch(config)# fabric-binding activate vsan 10
Activates the fabric binding database for the specified VSAN.
Step 3
switch(config)# no fabric-binding activate vsan 10
(Optional) Deactivates the fabric binding database for the specified VSAN.
Forcing Fabric Binding Activation
If the database activation is rejected due to one or more conflicts listed in the previous section, you may decide
to proceed with the activation by using the force option.
To forcefully activate the fabric binding database, follow these steps:
Procedure
Step 1 switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2
switch(config)# fabric-binding activate vsan 3 force
Activates the fabric binding database for the specified VSAN forcefully—even if the configuration is not
acceptable.
Step 3 switch(config)# no fabric-binding activate vsan 3 force
(Optional) Reverts to the previously configured state or to the factory default (if no state is configured).
