====== Arista Switch:DCS-7050QX-32-R ====== ---- * DCS-7050QX-N(config-if-Et24/2)#**show inventory** * DCS-7050QX-N(config-if-Et32)#**show interface ethernet 23/1-4 status** ---- ---- **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.
