Usage Guidelines

This command does not apply to all hardware platforms. For more information about feature support, see Fabric Engine User Guide.

If you enable this boot config flag, it decreases the scaling limits for the following features:

• Switched UNI (S-UNI) endpoints

• Layer 2 and Layer 3 I-SIDs

• IP Multicast over Fabric Connect local streams

The scaling numbers for the following items are limited by the use of a shared hardware resource, and thus they affect one another:

• the number of SPB nodes per area

• the number of SPB nodes that send IP Multicast streams that the local BEB receives

• local SPB services:

  • Layer 2 I-SIDs

  • Layer 3 I-SIDs

  • IP Multicast over Fabric Connect remote IP Multicast stream data I-SIDs

  • I-SID mirroring instances

For more information about maximum scaling numbers, see Fabric Engine Release Notes.
