You can use a CLI script to quickly configure the SPB and IS-IS infrastructure to enable Fabric Connect on a switch. You can use the SPB script, rather than manually configure the minimum SPBM and IS-IS parameters.

You can use the command run spbm to quickly configure the following:

Configure the SPB Ethertype.
Create an SPB instance.
Create an SPBM backbone VLAN and associate it to the SPB instance.
Create an SPBM secondary backbone VLAN and associate it to the SPB instance.
Add an SPB nickname.
Create a manual area.
Enable IS-IS on one of the switch interfaces.
Enable IS-IS globally.
Configure the IS-IS system name.
Configure the IS-IS system ID.
Configure SPBM port and MLT interfaces.
Clean up any SPBM configuration.

The following table displays the default values applied if you use the run spbm command. The SPB script creates some of the default values based on the MAC address of the switch, including the nickname and System ID value.


Parameter	Default values
Ethertype	0x8100
Primary B-VLAN	4051
Secondary B-VLAN	4052
Manual area	49.0000
Nickname	Derived from the chassis MAC
System name	IS-IS system name. By default, the system uses the global system name as the IS-IS system name, until you manually configure it. Also, the system does not save the global system name in the running configuration on the switch.
System ID value	Derived from the chassis MAC, using a different algorithm from that for the Nickname

Note

The SPB script only creates the SPBM instance, VLAN, and other parameters if they do not exist. For example, if the SPBM instance and VLAN already exist, the SPB script does not create them. If the SPB script is unable to create a parameter because it already exists, then the script stops and the system displays an error message.
