Command Mode CONFIGURATION
Usage
Information
● To verify the currently configured mode on a Fabric Engine, use the show switch-operating-
mode command. If a Fabric Engine is in Full Switch mode, you must manually provision a Fabric
Expander using the unit-provision command. This command assigns a unit ID to a service tag or
provision name. To transmit server traffic, you must configure the virtual port on the Fabric Expander
by entering the unit ID as the virtual-slot number using the interface ethernet node/
virtual-slot/port command.
● The no version of the command removes the Fabric Expander provisioning.
Example
OS10(config)# unit-provision 1/78 403RPK2
Supported
Releases
