Configuring minimum SPBM and IS-IS parameters
Use the following procedure to configure the minimum required SPBM and IS-IS parameters to enable SPBM operation on the switch.

Variable definitions
The following table defines parameters for the isis command.
Variable |
Value |
---|---|
enable |
Enables or disables the IS-IS circuit/interface on the specified port or MLT. The default is disabled. Use the no option to disable IS-IS on the specified interface. |
spbm <1–100> |
Enable the SPBM instance on the IS-IS interfaces. |
The following table defines parameters for the manual-area command.
Variable |
Value |
---|---|
<xx.xxx.xxx...xxx> |
Specifies the IS-IS manual-area (1–13 bytes in the format <xx.xxx.xxx...xxx>). Only one manual area is supported. For IS-IS to operate, you must configure at least one area. Use the no option to delete the manual area. |
The following table defines parameters for the spbm command.
Variable |
Value |
---|---|
<1–100> |
Creates the SPBM instance. Only one SPBM instance is supported. |
b-vid {<vlan-id [-vlan-id] [,...]} |
Sets the IS-IS SPBM instance data VLANs. Use the no option to remove the specified B-VLAN from the SPBM instance. |
nick-name <x.xx.xx> |
Specifies a nickname for the SPBM instance globally. The value is 2.5 bytes in the format <x.xx.xx>. Use the no or default options to delete the configured nickname. |
primary <1-4059> |
Sets the IS-IS instance primary data B-VLAN. |
The following table defines parameters for the vlan create command.
Variable |
Value |
---|---|
<2-4059> |
Specifies the VLAN ID. Creates an SPBM Backbone VLAN (B-VLAN). You can optionally specify a name for the SPBM B-VLAN. |
type {port-mstprstp|protocol-mstprstp|spbm-bvlan} |
Specifies the type of VLAN created.

Job aid
Important
After you have configured the SPBM nickname and enabled IS-IS. To maintain the same nickname with a different system ID, perform the following steps:
-
Disable IS-IS.
-
Change the system ID.
-
Change the nickname to a temporary one.
-
Enable IS-IS.
-
Wait up to 20 minutes for the LSPs with the original system ID to age out.
Note
To check the age out time, use the show isis lsdb sysid <original-sys-id> command on any of the other SPB nodes in the network. When there is no output from this command, proceed to the next step. The time left (in seconds) for the LSPs to age out is shown under the column LIFETIME.
-
Disable IS-IS.
-
Change the nickname to the original nickname.
-
Enable IS-IS.
