Base-VLAN Configuration

There are two aspects to base-VLAN configuration:

• ECT algorithm assignment
• Base-VLAN to SPVID mapping

The base-VLAN belongs to the boundary port where packets ingress and egress the SPBV region. The base-VLAN manages operations in the SPT and provides access to the SPB network. A given base-VLAN in an SPBV region must be assigned the same ECT algorithm. The ECT determines the next switch in the path through the SPB. There are 16 ECT algorithms defined in IEEE 802.1Qaq.

Use the set spb basevid ect-alg command in any command mode to assign an ECT algorithm to a base-VLAN.

The following example assigns ECT algorithm 2 to base-VLAN 100:

System(rw)->set spb basevid 100 ect-alg ieee 2
System(rw)->

By default, base-VLANs are dynamically mapped to a unique SPVID from the SPVID pool for each node in the SPBV region. You can administratively map the base-VLAN to an SPVID for each node in the SPBV region. To administratively configure the base-VLAN to SPVID mapping:

• Set the SPB VLAN mode to manual using the set spb system mode-vlan command in any command mode
• Map the SPVID to the base-VLAN using the spvid option of the set spb basevid ect-alg command

The following example maps SPVID 2000 to base-VLAN 100:

System(rw)->set spb system mode-vlan manual
System(rw)->set spb basevid 100 ect-alg ieee 2 spvid 2000
System(rw)->
