Default Configuration; Configuring Layer 2 (Data Link) Mode; Port Numbering Convention - Dell Networking Z9500 Getting Started Manual

Navigate CLI modes
The Dell prompt changes to indicate the CLI mode. You must move linearly through the command
modes, except for the end command which takes you directly to EXEC Privilege mode and the exit
command which moves you up one command mode level.

Default Configuration

A version of Dell Networking OS is preloaded onto the system; however, the system is not configured
when you power up for the first time (except for the default host name, which is Dell). You must
configure the system using the CLI.

Configuring Layer 2 (Data Link) Mode

To enable Layer 2 data transmissions through an individual interface, use the switchport command in
INTERFACE mode. You cannot configure switching or Layer 2 protocols, such as spanning tree protocol
(STP), on an interface unless the interface has been set to Layer 2 mode.
1. Enable the interface.
INTERFACE mode
no shutdown
2. Place the interface in Layer 2 (switching) mode
INTERFACE mode
switchport
To view the interfaces in Layer 2 mode, use the show interfaces switchport command in EXEC
mode.

Port Numbering Convention

On the switch, all ports operate by default in 40GbE mode. If you use a breakout cable, each port can
operate in 4x10GbE mode.
Ports are located on three line cards as shown below. The line cards are factory-installed and are not
hot-swappable or field-replaceable. On each line card, the fixed 40GbE ports are numbered from bottom
to top in multiples of four, starting with zero; for example, 0, 4, 8, 12, and so on. When a breakout cable is
installed, the resulting four 10GbE ports are numbered with the remaining numbers. For example, 40GbE
port 0 contains 10GbE ports 0, 1, 2, and 3; 40GbE port 4 contains 10GbE ports 4, 5, 6, and 7.
Line card 0 consists of ports 0 to 143; line card 1 consists of ports 0 to 191; line card 2 consists of ports 0
to 191.
