Creating an SPB VSI
SPBM uses a unique I-SID to identify an SPB VSI. An SPB VSI's I-SID must be the same across the SPBM network.
I-SID 255 is reserved for the fast channel. You cannot associate any Ethernet service instance with the VSI that uses I-SID 255.
To use the fast-channel feature, you must create a VSI and assign I-SID 255 to the VSI.
To create an SPB VSI:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a VSI. | vsi vsi-name | By default, no VSIs exist. |
3. Assign an SPB I-SID to the VSI. | spb i-sid i-sid | By default, a VSI does not have an SPB I-SID. You can configure one SPB I-SID and one PBB I-SID for one VSI, but the two I-SIDs cannot be the same. For more information about PBB, see Layer 2—LAN Switching Configuration Guide. |
