Configuring a Username and Password

To access the C9010 remotely, configure a system user name and password.

• Configure a user name and password to access the switch remotely.

CONFIGURATION mode

Dell(conf)# username username password [encryption-type] password

An encryption-type parameter is not necessary because it is 0 by default, which allows you to

enter the password in clear text.

Configure Layer 2 (Data Link) Mode

To enable Layer 2 data transmissions on a specified interface, use the switchport command in

INTERFACE mode.

You cannot configure switching or Layer 2 protocols, such as the Spanning Tree Protocol (STP), on an

interface unless the interface has been set to Layer 2 mode.

1. Enter interface configuration mode.

CONFIGURATION mode

Dell(conf)# interface tengigabitethernet 1/6

2. Enable the interface.

INTERFACE mode

Dell(conf-if-te-1/6)# no shutdown

3. Place the interface in Layer 2 (switching) mode.

INTERFACE mode

Dell(conf-if-te-1/6)# switchport

To view the interfaces in Layer 2 mode, enter the show interfaces switchport command in EXEC

or EXEC Privilege mode:

Dell# show interfaces switchport

Splitting QSFP+ Ports into SFP+ Ports

On a 6-Port 40GbE QSFP+ line card, you can split a single 40GbE QSFP+ port into four 10GbE SFP+

ports using one of the supported breakout cables. For a list of supported optics, contact your Dell

Networking representative or reseller.

A 40GbE (quad) port must be in a default configuration before you can split it into four 10GbE SFP+ ports.

When you split the port, the 40GbE interface configuration is lost in the running configuration. The CLI

split-port change immediately takes effect due to the dynamic fan-out feature; it is not necessary to

reload the system. Be sure that you also remove the 40GbE port from other L2/L3 feature configurations.

• Configure the switch to recognize the port mode change.
