2.3.3 Unit-Slot-Port Naming Convention

7300S Series Stackable Switch software references physical entities such as cards and
ports by using a Unit-Slot-Port (USP) naming convention. The 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.

Overview
Description
Logical slot and port number. This is applicable in the case of a
port-channel (LAG). You can use the logical unit/slot/port to
configure the port-channel.
Use double quotation marks to identify character strings, for
example, "System Name with Spaces". An empty string ("") is not
valid.
Description
Physical slot numbers begin with zero, and are allocated up to the
maximum number of physical slots.
Logical slots immediately follow physical slots and identify port-
channel (LAG) or router interfaces.
The CPU slots immediately follow the logical slots.
Description
The physical ports for each slot are numbered sequentially starting
from zero. For example, port one will be "0/1" with slot number
always as zero.
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.
CPU ports are handled by the driver as one or more physical
entities located on physical slots.
