Auto Fabric is a feature that allows plug-and-play for Brocade VDX switches.
A type of configuration known as bare-metal is required for a switch to join an existing VCS cluster by means of plug and play. The cluster must be a logical chassis cluster.
Bare-metal configuration is a profile that contains a WWN-to-RBridge ID mapping. You first must pre-configure this mapping in the existing VCS cluster to allow the bare-metal switch to join the cluster. A switch with its bare-metal flag set to true (which is the factory default) can request the following required configuration settings from a physically connected neighbor that already belongs to the cluster:
- VCS ID
- RBridge ID
- VCS mode
- Global VLAN state
From this information, the bare-metal switch auto-configures itself and reboots with the bare-metal flag now disabled. (Any configuration performed on the switch disables the bare-metal flag, but you may need to toggle the ISL. However the bare-metal configuration on the remaining nodes in the cluster remains intact. ) Bare-metal state must be disabled for cluster formation to occur.
