Slot/Port Naming Convention
FASTPATH software references physical entities such as cards and ports by using a slot/port naming convention.
The FASTPATH software also uses this convention to identify certain logical entities, such as Port-Channel
interfaces.
The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case
of logical and CPU ports it also identifies the type of interface or port.
The port identifies the specific physical port or logical interface being managed on a given slot.

Using the “No” Form of a Command
The no keyword is a specific form of an existing command and does not represent a new or distinct command.
Almost every configuration command has a no form. In general, use the no form to reverse the action of a command
or reset a value back to the default. For example, the no shutdown configuration command reverses the shutdown
of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature
that is disabled by default. Only the configuration commands are available in the no form.

FASTPATH Modules
FASTPATH software consists of flexible modules that can be applied in various combinations to develop advanced
Layer 2/3/4+ products. The commands and command modes available on your switch depend on the installed
Table 3: Type of Slots
Slot Type
Description
Physical slot numbers
Physical slot numbers begin with zero, and are allocated up to the maximum
number of physical slots.
Logical slot numbers
Logical slots immediately follow physical slots and identify port-channel (LAG)
or router interfaces.
CPU slot numbers
The CPU slots immediately follow the logical slots.
Table 4: Type of Ports
Port Type
Description
Physical Ports
The physical ports for each slot are numbered sequentially starting from zero.
Logical Interfaces
Port-channel or Link Aggregation Group (LAG) interfaces are logical interfaces
that are only used for bridging functions.
VLAN routing interfaces are only used for routing functions.
Loopback interfaces are logical interfaces that are always up.
Tunnel interfaces are logical point-to-point links that carry encapsulated
packets.
CPU ports
CPU ports are handled by the driver as one or more physical entities located on
physical slots.
Note: In the CLI, loopback and tunnel interfaces do not use the slot/port format. To specify a loopback
interface, you use the loopback ID. To specify a tunnel interface, you use the tunnel ID.
