1.3 Slot/Port Naming Convention
FASTPATH software references physical entities such as cards and ports by using a
unit/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.
NOTE: In the CLI, loopback and tunnel interfaces do not use the unit/slot/port
format. To specify a loopback interface, you use the loopback ID. To
specify a tunnel interface, you use the tunnel ID.
Interface or
unit/slot/port Valid slot and port number separated by forward slashes. For example,
0/1 represents slot number 0 and port number 1.
Logical Interface Represents a 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.
Character strings Use double quotation marks to identify character strings, for example,
“System Name with Spaces”. An empty string (“”) is not valid.
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 encap-
sulated packets.
CPU ports CPU ports are handled by the driver as one or more physical enti-
ties located on physical slots.
