Configuring Shortest Path Bridging VLAN

This section provides default Shortest Path Bridging values and a procedure for configuring a Shortest Path Bridging system.

Default Shortest Path Bridging Parameters

Parameter	Description	Default Value
SPB Status	Shortest Path Bridging device global state.	enabled
SPB Port Status	Shortest Path Bridging port state.	disabled
SPB System VLAN Mode	Configures the mode that determines whether the base-VID to SPVID mapping is manual or dynamic (auto).	auto
SPB Digest-Convention	Configures the SPB agreement digest convention.	loopfreeboth
Spanning Tree Version	Configures the Spanning Tree version; SPB requires SPT version 4	MSTP (version 3)

The following procedure describes Shortest Path Bridging configuration on the S- K- and 7100-Series devices. All commands used to configure Shortest Path Bridging can be entered in any command mode.

Configuring Shortest Path Bridging

Step	Task	Command(s)
1	Configure Spanning Tree on all SPB region devices.	See the S-, K-, and 7100 Series CLI Reference Guide for Spanning Tree Configuration information.
2	Enable SPB globally on the device. SPB is globally enabled by default.	set spb status {enable | disable}
3	Set the Spanning Tree version to SPT on all devices in the SPB region.	set spantree version spt
4	Configure the same Spanning Tree MST configuration name on all devices in the SPB region.	set spantree mstcfgid {[cfgname name] [rev level]}
5	Configure an SPVID pool for this SPB region.	set spantree mstmap spvid-list sid {4095 | spvid}
6	Configure base-VLANs to use SPB.	set spantree mstmap baseVid-list sid {4093 | spbv}
7	Assign the ECT algorithm for each base-VLAN on this device.	set spb basevid baseVid ect-alg ieee ect-alg
8	Optionally, set SPB system parameters: IS-IS area, digest convention, VLAN mode, or system ID.	set spb system [area-address isis-area] [digest-convention {off | loopfreeboth}] [mode-vlan {auto | manual}] [system-id system-id]
9	Optionally, administratively assign the base-VLAN to SPVID mapping for the base-VLAN on each device in the SPB region.	set spb basevid baseVid spvid spVid
10	Enable SPB on all ports that will take part in the SPB region.	set spb port port-string status enable
