1. Configuration command line interface
This section describes methods to use the command line interface, you can manage the network
equipment by using the command line interface
1.1. Command mode
Device management interface is divided into a number of different models, the user the command
mode determines the commands that you can use.
Enter a question mark button at the command prompt (?) can list every command mode to support the
use of command. When a user and network equipment management interface, a new session is
connected, the user first in the user model (User EXEC model)，You can use the user mode command.
In user mode, can only use a small amount of commands, and command functions also have some
limitations, such as the show command. User mode command operating results will not be saved.
To use all of the commands, you must first enter privilege mode (Privileged EXEC).Usually, enter
privilege mode password must enter privilege mode. In privileged mode, the user can use all the
privileges of command, and can enter global configuration mode.
Use the configuration mode (global configuration mode, interface configuration mode) command, will
have an impact on the current running configuration. If the user to save the configuration information,
these commands will be preserved, and perform again at system restart. To enter configuration mode,
you must first enter global configuration mode. Starting from the global configuration mode, can enter
interface configuration mode and other configuration sub model.
The following table lists the command mode, how to access each mode, mode of prompt, how to leave

3. Configuration interface
3.1. Interface type Summary
This chapter mainly to Ruijie equipment interface types are divided, and a detailed definition of each
interface type interface type Ruijie equipment can be divided into the following two categories：
(L2 interface)
(L3 interface) (Layer three device support)
3.1.1. This section describes the type two layer interface and the related
definition, can be divided into the following types (L2 interface)
This section describes the type two layer interface and the related definition, can be divided into the
following types
Switch Port
Link-aggregation Port
3.1.2. Switch Port
Switch Port consists of a single physical port on the device, only the two layer switching function. The
port can be a Access Port, Hybrid Port or a Trunk Port, you can use the Switch Port interface
configuration command, a port configured as a Access Port, Hybrid Port or Trunk Port.Switch Port is
used to manage the physical interface and the second related protocols, and does not handle routing
and bridging.
3.1.3. Access Port
Each Access Port can only belong to one VLAN, it only belongs to the VLAN transmission frame is
generally used to connect computers..
The default VLAN:
Each Access Port belongs to only one VLAN, so the default VLAN it is the VLAN, can not use the
settings.
Computer
Receiving and sending frames
Access Port sends out the data frame is not with the TAG, and it can only receive the following three
forms of frame：
Untagged Frame
VID IS Access Port VLAN Tagged Frame
Untagged Frame
The Access Port to receive frames without the TAG ,And for the without TAG frame add default
VLAN TAG, Before sending to remove add TAG, send again.
Tagged Frame
The received data frame to the Access port with TAG, will be in accordance with the following
conditions for processing:

When the TAG VID (VLAN ID) the same with the default VLAN ID, receiving the data frame, and
removed when it is sent
The TAG sign and send.
When the TAG VID (VLAN ID) as the default VLAN ID, receiving the data frame. In TAG, VID =
default VLAN ID for the identification of priority.
3.1.4. Trunk Port
Trunk port can belong to multiple VLAN, capable of receiving and transmitting belong to more than
one VLAN frame, generally used for connection between devices, can also be used to connect the
user's computer.
The default VLAN
Because Trunk Port can belong to more than one VLAN, so we need to set up a Native VLAN as the
default VLAN. when switching Trunk port received no VLAN tag with the frame to the frame, it
increases the Native VLAN label, the frame belongs to Native VLAN; when Trunk port sends frame, if
the frame of VLAN and Native same as VLAN, will remove the VLAN label.
Tip
Recommend the end device Trunk port of the native VLAN and the end
Trunk port of the native VLAN configuration is consistent, otherwise may
not be the correct port forwarding packets.

Receiving and sending frames
Trunk port can receive Untagged frame and tagged frame.Trunk port allows Port to send VLAN range
of non Native VLAN frame are TAG, sending Native VLAN frame without TAG.
Untagged Frame
If the received Trunk port frame without IEEE802.1Q TAG, then the frame in the interface of the Native
VLAN transmission.
Tagged Frame
If the received frame is Trunk port TAG, will be in accordance with the following conditions for
processing:
receiving the data frame; in sending the frame, remove and send TAG.
AN, but
VID
Tip The Untagged message is ordinary Ethernet message, the PC card can
identify this message communication; change of the TAG message
structure is in the source MAC address and a destination MAC address,
plus the 4bytes VLAN information, namely VLAN TAG head.

3.1.5. Hybrid port
Hybrid type of port can belong to multiple VLAN, can message receiving and transmitting a plurality of
VLAN, can be used for the connection between devices, can also be used for different user
computer.Hybrid port and the Trunk port is sending Hybrid port allows multiple VLAN message without
a label, and only allowed to send the default Trunk port VLAN message without a label, the need to pay
attention to is: Hybrid port with VLAN must already exist.
3.1.6. Link-aggregation Port
Link-aggregation Port is formed by multiple physical member port aggregation. We can take multiple
physical links tied together to form a simple logical link, link, the logic we call a Link-aggregation Port.
For the two layer switch AP is like a high bandwidth Switch port, it allows multiple port bandwidth
stacking up,,,,,,,,, expanding the bandwidth. In addition, through the Link-aggregation, Port frames
transmitted will be in the Link-aggregation Port member port on flow balance, if a member link in AP
failure, Link-aggregation Port will automatically transfer the link traffic to other effective members of the
link, improve the reliability of the connection.
3.1.7. (L3 interface)
This section describes the type three layer interface and the related definition, can be divided into the
following types
SVI (Switch virtual interface)
The SVI is switched virtual interface, to achieve the three layer switch interface to.SVI logic can be
used as a management interface of the machine, through the management interface, administrators
can manage the equipment.
You can through the interface VLAN interface configuration command to create a SVI, and then to the
SVI IP address assigned to the establishment of VLAN
Routing between.
3.2. Configuration interface
This section describes the default configuration, interface configuration guide, configuration steps,
configuration example
3.2.1. Interface ID rules
For Switch Port, the numbers start at 1.
For Link-aggregation Port, the number of the number of AP support the 116 equipment. For SVI, its
number is the SVI corresponding VLAN VID.
3.2.2. Using the interface configuration command
You can be in the global configuration mode. Use the Interface command to enter interface
configuration mode..
command
Function
Switch(config)# Interface
gigabitEthernet port- ID
Enter the Interface gigabitEthernet _ID
command in global configuration mode, enter
interface configuration mode.
Under the given into the Gigabitethernet 0/1 interface example：
Switch(config)# interface gigabitEthernet 0/1
Switch(config-if-gigabitEthernet-0/1)#

In interface configuration mode you can attribute configuration interface.
You can use interface in global configuration mode command into the SVI interface configuration
mode.
Command
Function
Switch(config)# interface vlan vlan ID
Enter the interface command in global configuration
mode, enter the SVI interface configuration mode.
Under the given into the interface vlan1 interface example：
Switch(config)# interface vlan 1
Switch(config-if-vlan1)#
In the SVI interface configuration mode you can configure the IP address of the interface.
3.2.3. Select the interface media type
Some of these interfaces, can have a variety of media types for the user to choose. You can choose
one kind of medium. Once you have selected the medium type, connection status, speed, duplex,
fluidic attribute interface all refer to the properties of the medium type, if you change the media type, the
new media types of these properties will use the default values, you can according to need to set these
properties.
This configuration command only to the physical port.Link-aggregation Port and the SVI interface is not
supported media type setting. This configuration command only for media port.
Configuration for the Link-aggregation Port member export port, the medium type must be consistent,
otherwise cannot be added to the AP.
The Link-aggregation port type Port members and can not be changed.
3.2.4. Configuration interface description and management state
In Command to help you remember an interface function for each interface, you can come up with a
name that identifies this interface, also is the description of the interface (Description). You can set the
interface according to the specific name, to express the meaning of such as: you want to put the
Gigabitethernet 0/1 assigned to the user A special use, you can use this interface description is set to
"User A”.
Command
Function
Switch(config-if-gigabitEthernet-0/2)#
description string
Set interface description, up to a maximum of
240 characters.
The following example shows how to set the interface Gigabitethernet 0/1 description：
Switch# config terminal
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if-gigabitEthernet-0/1)#description User A

Command
Function
Switch(config-if-gigabitEthernet-0/1)#

The rate parameter setting interface, or set to
auto:
1000 only to Gigabit mouth;
Switch(config-if-gigabitEthernet-0/1)#
duplex {auto | full | half }
Duplex mode interface.
Be careful.
Gigabit ports can only be set to Full mode;
In some cases, may need to disable an interface. By setting the interface management state to close
the corresponding interface. If you close an interface, the interface will not receive and transmit any
frames, all functions will lose the interface corresponding to. Also by setting up the management state
to re open the closed interface interface management state has two types: Up and Down, when the
interface is closed, interface management state is down, otherwise up
Command
Function
Switch(config-if-gigabitEthernet-
0/1)# {shutdown|no
shutdown}
Close an interface or open an interface
The following example describes how to close the interface 0/1：
Switch# config terminal
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if-gigabitEthernet-0/1)# shutdown
The following example describes how to enable the interface 0/1:
Switch# config terminal
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if-gigabitEthernet-0/1)#no shutdown
3.2.5. This section describes how to configure the interface speed, duplex mode.

Step 1
Step 2
3.2.6. The configuration interface MTU
When a port for high throughput data exchange, may encounter greater than Ethernet frame length
frame, this frame is called
Jumbo frame. The user can set the port MTU to control the maximum frame the port allows the
transceiver. MTU is the effective data frame length, not including Ethernet encapsulation overhead.
Port received or forwarding of frames, if the length is more than the MTU, will be discarded.
MTU allows setting for 64~10240 bytes, 1518 bytes by default.
This configuration command only to the physical port.SVI interface does not support the MTU setting.
