Quick Steps for Configuring Automatic Fabric
The following steps provide a quick tutorial for setting up a basic Automatic Fabric configuration. This
scenario applies to the default operation of a switch without a configuration file, as well as configuring a
switch with an existing configuration file. Additional information about how to configure Automatic
Fabric is provided in the section
“Configuring Automatic Fabric” on page 14-24.
Automatic Fabric Operation with No Configuration File
When the switch boots up and there is no configuration file, the Automatic Fabric operation is
automatically enabled and triggers the following discovery process:
1 The switch will attempt to discover and automatically set up an LACP configuration.
2 After the LACP discovery process completes, the switch will attempt to discover and automatically set
up a Shortest Path Bridging (SPB) configuration. This includes discovering and configuring SPB
adjacencies, UNP SPB access ports, and UNP SPB Service Access Points (SAPs).
3 After the SPB discovery process completes, the switch will attempt to discover and automatically set
up an MVRP configuration.
4 The automatic discovery process for IP protocols takes place in parallel with the discovery process for
the other supported Automatic Fabric protocols (as described in Steps 1, 2, and 3).
Once the switch boots up and the Automatic Fabric process has completed, the default settings for the
Automatic Fabric parameters can be configured.
Configuring Automatic Fabric Parameters
When a switch is already up and running with an existing configuration file, it is possible to change
default parameter settings (see
“Automatic Fabric Default Values” on page 14-4) to fine tune the
Automatic Fabric operation going forward.
1 To change the global administrative status of Automatic Fabric for the switch, use the auto-fabric
admin-state command. For example:
-> auto-fabric admin-state disable
2 To change the status of Automatic Fabric on specific ports, use the auto-fabric admin-state command
with the interface parameter. For example:
-> auto-fabric interface 1/1/1-4 admin-state disable
The Automatic Fabric status configured for a port takes precedence when the global status is enabled
for the switch. For example, if Automatic Fabric is disabled on a port but globally enabled for the
switch, Automatic Fabric will not run the discovery process on that port.
3 To change the status of Automatic Fabric discovery for specific protocols, use the auto-fabric
protocols command. For example:
-> auto-fabric protocols lacp admin-state enable
-> auto-fabric protocols mvrp admin-state enable
-> auto-fabric protocols spb interface 1/1/3 admin-state disable
-> auto-fabric protocols ip ospfv2 admin-state enable
-> auto-fabric protocols ip ospfv3 admin-state disable
-> auto-fabric protocols ip isis admin-state disable
