configure forwarding switch-fabric protocol

configure forwarding switch-fabric protocol [standard | enhanced]


Configures the switch-fabric protocol on a BlackDiamond 8800 series switch.

Syntax Description

standard Specifies the standard protocol, which is supported on all switches.
enhanced Specifies the enhanced protocol, which is supported only on BlackDiamond 8900 series modules, BlackDiamond X8, and Summit series switches. The enhanced protocol is required to support MPLS.



Usage Guidelines

To support MPLS, the BlackDiamond 8800 series switch must use one or two 8900-MSM128 cards and only the following BlackDiamond 8900 series modules: 8900-G96T-c and all BlackDiamond 8900 xl- and xm-series modules.



You do not need to reboot the switch to activate the protocol change, but there will be some traffic interruption during protocol activation.

If MPLS is enabled on the switch, you must disable MPLS before you can change the stacking protocol to standard.

To display the switch-fabric protocol configuration, enter the show forwarding configuration command.


To configure a switch to use the enhanced protocol, enter the following command:

configure forwarding switch-fabric protocol enhanced


This command was first available in ExtremeXOS 12.5.

Platform Availability

This command is available only on BlackDiamond 8800 series switches that have the proper hardware installed as described in the Feature License Requirements document.
