Enabling or Disabling Automatic Fabric
Automatic Fabric is enabled globally for the switch when any of the following events occur:
• The switch boots up with no configuration file or the configuration file size is zero.
• The switch boots up with an existing configuration file that has the following Automatic Fabric entry:
-> show configuration snapshot auto-fabric
! Dynamic auto-fabric:
auto-fabric admin-state enable
• The auto-fabric admin-state command is used with the enable parameter option while the switch is
up and running. For example:
-> auto-fabric admin-state enable
Automatic Fabric is also enabled on a per port basis using the auto-fabric admin-state command with the
interface parameter. For example:
-> auto-fabric interface 1/1 admin-state enable
It is important to note that the port level setting for Automatic Fabric overrides the global switch setting.
For example, if Automatic Fabric is globally enabled for the switch but disabled on port 1/2, Automatic
Fabric does not activate automatic discovery on that port.
To disable Automatic Fabric globally or on a per-port basis, use the auto-fabric admin-state command
with the disable parameter option. For example:
-> auto-fabric interface 1/1 admin-state disable
-> auto-fabric admin-state disable
When Automatic Fabric is globally disabled for the switch, the following configuration settings are
removed unless they were previously saved to the switch configuration file:
• Spanning Tree is set back to the default 1x1 mode. This only occurs if there are no VLAN registrations
on any port or link aggregate.
• SPB is globally disabled, which removes BVLANs 4000-4015 and administratively disables SPB. This
only occurs if there are no SPB adjacencies formed on any ports or link aggregates.
