Advanced Feature Bandwidth Reservation Note:
If your switch does not have this boot flag, it is because the hardware reserves the bandwidth automatically with no user interaction. |

The switch enables the boot config flags advanced-feature-bandwidth-reservation command by default to use advanced features on the switch. If you disable the boot config flags advanced-feature-bandwidth-reservation command and attempt to enable an advanced feature, the switch displays an error message to explain why the advanced feature failed to start, and to remind you that you must enable this boot configuration flag for that advanced feature.
Important
If you change the configuration, you must save the configuration, and then reboot the switch for the change to take effect.
If you disable this feature and save the configuration, any configuration for advanced features remains saved in the configuration file but is not used.
By default, this boot configuration flag is enabled with the low level option.
When disabled, you can use all ports for Layer 2 or Layer 3 forwarding of standard unicast and multicast features. Use this mode if you are not configuring advanced features. The syntax for disabling this boot configuration flag is no boot config flags advanced-feature-bandwidth-reservation.
When enabled, also known as Full Feature mode, the switch supports advanced features by reassigning some of the front panel ports to be loopback ports.
The following advanced features require loopback ports:
Note
Full Feature mode does not support PIM.
The syntax for enabling the boot flag for this mode is: boot config flags advanced-feature-bandwidth-reservation [low | high ].
When you select low or high, the corresponding bandwidth of the reserved Ethernet ports is allocated to the loopback required for advanced feature functionality.
Note
You can consider using low bandwidth mode instead of high bandwidth mode to free up two reserved ports for use as regular ports.
After the switch reserves the appropriate ports to become loopback ports, the ports are no longer visible in the output when you enter show interfaces gigabitEthernet.
Important
If you change the configuration, you must save the configuration, and then reboot the switch for the change to take effect.
If you disable this feature and save the configuration, any configuration for advanced features remains saved in the configuration file but is not used.
The following table lists the ports reserved as loopback ports:
| Product | Reserved loopback ports |
|---|---|
| VSP 7432CQ |
Low reserves ports 1/31 and 1/32. High reserves ports 1/29, 1/30, 1/31, and 1/32. |
| VSP 7400-48Y |
Low reserves ports 1/55 and 1/56. High reserves ports 1/53, 1/54, 1/55, and 1/56 |
Important
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 stops loading the configuration.
Note
Product Notice: This feature is available in demo mode only on XA1480 and supports low level parameter configuration automatically, which cannot be modified.
When disabled, all I-SID bindings are removed and the switch can only operate as a Backbone Core Bridge (BCB). The syntax for disabling this boot configuration flag is: no boot config flags advanced-feature-bandwidth-reservation.
When enabled, the switch reserves CPU cores for Backbone Edge Bridge (BEB) functionality. The syntax for enabling the boot flag for this mode is: boot config flags advanced-feature-bandwidth-reservation low.
