Use manual configuration when you want precise control over items such as slot number
                assignment.
            To manually setup up Extended Edge
					Switching:
        
        - 
                Physically set up the bridge
                    port extender(s) (BPEs). See the applicable Virtual Port Extender Quick
                        Reference Guide.
                
                    
Note   
If you are using
                        unconfigured (
unconfigure switch all) or "out-of-the box" controlling bridge
                        switches (CBs), to ensure that full automation does not start to run, do 
not reboot the CBs
                        after connecting the BPEs. 
 
                 
             - 
                On the CB, 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 5520.14 #
 
             - 
                (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}
Note   
You cannot convert a
                        cascade port to a LAG after the cascade port is created without first
                        unconfiguring the slot from the cascade port.
 
 
             - 
                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 BPE,
                    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).
             - 
                (Optional) Add a descriptive name to a BPE. Use the command:
                
configure slot
        slot
        description [ slot_description | none ]
