Create a platform VLAN using the command vlan create <vlan-id> type port-mstprsp <msti-instance>. Enable Layer 3 services on the platform VLAN and is associated with the Switched UNI (S-UNI) Service Instance Identifier (I-SID). All S-UNI ports are added to the platform VLAN.
You must associate the S-UNI I-SID to the platform VLAN. After you associate the platform VLAN with the I-SID, it becomes a CVLAN.
The switch performs MAC and ARP learning on the platform VLAN.
Note
You cannot add S-UNI ports or MLT to the S-UNI platform VLANs directly. Add the ports to the I-SID and assign the I-SID to the platform VLAN.
You can associate only port based VLAN with S-UNI I-SID.
