Netgear GSM7228PS-100NAS 사용자 설명서

The port identifies the specific physical port or logical interface being managed on a given 
slot.

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.

Using a Command’s “No” Form

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.

Managed Switch Modules

Managed switch 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 modules. Additionally, for some 
show

 commands, the output fields might change based on the modules included in the 

software.

The software suite includes the following modules:

Switching (Layer 2)

Routing (Layer 3)

IPv6—IPv6 routing

Multicast

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.
