Configuring Bridge Port Extenders
    
    
        
            To set up bridge port extenders:
         
        
            - 
                Physically set up the bridge port extender. See
                    the V400 Port Extender Quick Reference Guide.
            
- 
                On the controlling bridge switch, enable VPEX
                    mode. Use the command:
                enable vpex This command enables VPEX mode and allows
                    you to refer to ports in the  slot: port notation in applicable commands. A reboot is required for
                    the command to take effect. After rebooting, the CLI prompt changes to show that
                    the switch is now slot 1 (for
                    example): Slot-1 VPEX X670G2-48x-4q.14 # 
- 
                (Optional) Set up a LAG with LACP on the switch to
                    operate as the cascade port. Use the command:
                enable sharing port
                grouping
                port_list {algorithm [address-based {L2 | L3 | L3_L4 | custom}  | 
                    port-based
                 }]} {resilient-hashing [on |
                    off]} {distribution-mode
                    [all | local-slot | port-lists]} {lacp | health-check} 
- 
                Assign a slot number identifier to the attached
                    BPE on the specified cascade port. Use the command:
                configure vpex
        ports
        port_list
        slot
        slot_num Note    If the cascade
                        port is part of a LAG, then configure the LAG master port as the VPEX
                        port. 
 The behavior of this command is similar
                    to configuring slots within a chassis. After assigning a slot number to the port
                    extender, you can make port-level configuration choices with the familiar
                        slot:port notation in other
                    commands involving the port extender's ports (for example, configure vlan v1 add port
                    100:1).
