• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port
information.
2. Enable the interface.
INTERFACE mode
no shutdown
To confirm that the interface is enabled, use the show config command in INTERFACE mode. To leave
INTERFACE mode, use the exit command or end command. You cannot delete a physical interface.
Physical Interfaces
The Management Ethernet interface is a single RJ-45 Fast Ethernet port on a switch.
The interface provides dedicated management access to the system.
Line card interfaces support Layer 2 and Layer 3 traffic over 10-Gigabit Ethernet and 40-Gigabit Ethernet
interfaces. These interfaces can also become part of virtual interfaces such as virtual local area networks
(VLANs) or port channels.
For more information about VLANs, refer to Bulk Configuration. For more information on port channels,
refer to Port Channel Interfaces.
Dell Networking OS Behavior: The Z9500 system uses a single MAC address for all physical interfaces.

Port Pipes

A port pipe is a Dell Networking-specific term for the hardware packet-processing elements that handle
network traffic to and from a set of front-end I/O ports. The physical, front-end I/O ports are referred to
as a port set.
In the command-line interface, a Z9500 port pipe is entered as portset port-pipe-number.
A line card is a Dell Networking-specific term that describes the subsystem for a logical grouping of one
or more port pipes. The Z9500 has three line-card subsystems (0-2) with fixed, front-end ports. Each
Z9500 line card consists of several port pipes. Line card 0 consists of three port pipes: 0 to 2; line cards 1
and 2 consist of four port pipes: 0 to 3.
The ports and port pipes on each Z9500 line card are as follows:
• On line card 0, ports 0 to 47 belong to port pipe 0; ports 48 to 95 belong to port pipe 1; ports 96 to
143 belong to port pipe 2.
• On line card 1, ports 0 to 47 belong to port pipe 0; ports 48 to 95 belong to port pipe 1; ports 96 to
143 belong to port pipe 2; ports 144 to 191 belong to port pipe 3.
• On line card 2, ports 0 to 47 belong to port pipe 0; ports 48 to 95 belong to port pipe 1; ports 96 to
143 belong to port pipe 2; ports 144 to 191 belong to port pipe 3.
Refer to Port Numbering Conventionfor the exact port location on Z9500 line cards.

Network Processing Units (NPUs)

The Z9500 uses network processing units (NPUs) to process traffic from front-end I/O ports and
interconnect packet-processing elements in the chassis to form one fully connected logical switch. The
