• no boot config flags spbm-node-scaling

Default

The default is disabled.

Command Mode

Global Configuration

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

If you enable this boot config flag:

1. The switch supports up to 500 nodes per area.

2. The switch supports up to 200 nodes per area, when all of them are concurrently sending IP Multicast over Fabric Connect streams while local BEB receives.

3. The switch supports a maximum of 500 Switched UNI (S-UNI) endpoints.

If you disable this boot config flag (default configuration):

1. The switch supports up to 350 nodes per area.

2. The switch supports up to 150 nodes per area, when all of them are concurrently sending IP Multicast over Fabric Connect streams while local BEB receives.

3. The switch supports a maximum of 1,000 Switched UNI (S-UNI) endpoints.
