Enables the switch to support advanced features such as SPB, SMLT, and vIST by reserving ports as loopback ports.
boot config flags advanced-feature-bandwidth-reservation high
boot config flags advanced-feature-bandwidth-reservation low
default boot config flags advanced-feature-bandwidth-reservation
no boot config flags advanced-feature-bandwidth-reservation
The boot flag is enabled by default in the low level configuration, which means the switch operates in Full Feature mode but with less bandwidth to support minimum functionality for advanced features.
Global Configuration
This command does not apply to all hardware platforms. For more information about feature support, see VOSS Feature Support Matrix.
If your switch does not support this boot configuration flag, it is because the hardware reserves the bandwidth automatically with no user interaction.
You must save the configuration and restart the switch for a configuration change to take effect.
You must ensure your configuration does not include reserved ports before you enable this feature. If the configuration includes reserved ports after you enable this feature and restart the switch, the switch aborts loading the configuration.
