ONVENTION
Unified Switch software references physical entities such as cards and ports by using a slot/port naming convention. The
Unified Switch 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.

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.
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.
CPU ports CPU ports are handled by the driver as one or more physical entities located on physical
slots.
Note: In the CLI and loopback interfaces do not use the slot/port format. To specify a loopback interface, you use
the loopback ID.
