Unit/Slot/Port Naming Convention - NETGEAR M6100 Series Reference Manual

unit/slot/port Naming Convention

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

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.
M6100 Series Switches
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 value of logical slot numbers depend on the
type of logical interface and can vary from platform to platform.
The CPU slots immediately follow the logical slots.
Description
The physical ports for each slot are numbered sequentially starting from one.
For example, port 1 on slot 0 (an internal port) for a switch is 1/0/1, port 2 is
1/0/2, port 3 is 1/0/3, and so on.
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 are handled by the driver as one or more physical entities located
on physical slots.
