boot config flags advanced-feature-bandwidth-reservation

Enables the switch to support advanced features such as SPB, SMLT, and vIST by reserving ports as loopback ports.

Syntax

Command Parameters

high
Reserves the maximum bandwidth for the advanced features. Depending on the hardware platform, the number of reserved ports is different.
low
Reserves less bandwidth to support minimum functionality for advanced features. Depending on the hardware platform, the number of reserved ports is different.
vim
Reserves the internal Versatile Interface Module (VIM) ports as loopback ports.

Default

The default for XA1400 and 5420 series is enabled with low level which means the switch operates in Full Feature mode but with less bandwidth to support minimum functionality for advanced features. The default for 5520 series is enabled with vim level if VIM is not installed in the switch, else low level is enabled.

Usage Guidelines

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.

The vim parameter is only supported on the 5520 Series.
