**Breakout Interfaces**

**QSFP+** Ethernet Interface Configuration **Each QSFP+ module Ethernet interface is configurable as a single 40G port or as four 10G ports**. 

The switch displays four ports for each interface. Each port’s status depends on the interface configuration: 
• The /1 port is active (**connected** or **not connected**), regardless of the interface configuration. 
• The /2, /3, and /4 ports are **error-disabled** when the interface is configured as a single 40G port; 
• all ports are active (**connected** or **not connected**), when the interface is configured as four 10G ports. 

__Example:__
 
• On DCS-7050S-64, interface 49 is a QSFP+ interface. Its ports are listed as 49/1, 49/2, 49/3, and 49/4. Port status depends on the interface configuration: 

— 40G port configuration: 49/1 is **connected** or **not connected**; 49/2, 49/3, and 49/4 are **error-disabled**.
 
— 4x10G port configuration: 49/1, 49/2, 49/3, and 49/4 status is **connected** or **not connected**. 

The **speed forced 40gfull** command configures a QSFP+ Ethernet interface as a 40G port. The **no speed forced 40gfull** command configures a QSFP+ Ethernet interface as four 10G ports. These commands reset the forwarding agent, which disrupts traffic on all switch ports. These commands must be applied to the /1 port.


Unordered List ItemEnter Interface Ethernet configuration mode for port /1 of the QSFP+ Ethernet interface. 

switch(config)#**interface ethernet 49/1**

Enter speed force 40gfull command: 

switch(config-if-Et49/1)#**speed forced 40gfull**

//Note: This step **restarts the forwarding agent**, which **disrupts traffic on all switch ports**. The agent may require more than a minute to restart.//

Enter show interface status to confirm the change in configuration. 

switch(config-if-Et49/1)#**show interface status**

To configure a **QSFP+ Ethernet** interface as **four 10G port interfaces**:

Enter Interface Ethernet mode for port /1 of the QSFP+ interface. 

switch(config)#**interface ethernet 49/1** 

switch(config-if-Et49/1)#

Enter no speed force 40gfull command. 

switch(config-if-Et49/1)#**no speed forced 40gfull**

  spanning-tree vlan 504 priority 12288
  spanning-tree vlan 505 priority 12288
  spanning-tree vlan 506 priority 12288


For access ports (**connected to endpoints like PCs/servers**), use PortFast to speed up link transitions:

  interface Ethernet1
    spanning-tree portfast
    no shutdown

**This prevents unnecessary STP calculations when connecting non-switch devices.**

  spanning-tree vlan 1 priority 4096
  spanning-tree vlan 10 priority 4096

**This forces VLAN 1 and VLAN 10 to select this switch as the root.**

  interface Ethernet3
    spanning-tree bpdufilter enable
    spanning-tree bpduguard enable
    no shutdown

**BPDU Filter**: Stops sending/receiving STP packets on that port.
**BPDU Guard**: Disables the port if it receives STP packets (useful on access ports).
