Using the CLI

1.1 Accessing the CLI
You can log on to the switch and access the CLI by logging on to the switch remotely by a
Telnet or SSH connection through an Ethernet port.

1.1.1 Logon by Telnet
To log on to the switch by a Telnet connection, please take the following steps:
1.

Click Start and type in cmd in the Search programs and files window and press the Enter
button.

Figure 1-1 Run Window
2.

Type in telnet 192.168.0.1 in the cmd window and press Enter.

Figure 1-2 Type in the telnet command

3.

Type in the login username and password (both admin by default). Press Enter and you will
enter User EXEC Mode.

Figure 1-2 Log in the Switch
4.

Type in enable command and you will enter Privileged EXEC Mode.

By default no

password is needed. Later you can set a password for users who want to access the
Privileged EXEC Mode.

Figure 1-3 Enter into Priviledged EXEC Mode

1.1.2 Logon by SSH
To log on by SSH, a Putty client software is recommended. There are two authentication modes
to set up an SSH connection:

Password Authentication Mode: It requires username and password, which are both admin by
default.
Key Authentication Mode: It requires a public key for the switch and a private key for the SSH
client software. You can generate the public key and the private key through Putty Key
Generator.
Note:

Before SSH login, please follow the steps shown in Figure 1-4 to enable the SSH function
through Telnet connection.

Password Authentication Mode

1.

Open the software to log on to the interface of PuTTY. Enter the IP address of the switch
into Host Name field; keep the default value 22 in the Port field; select SSH as the
Connection type.

Figure 1-5 SSH Connection Config

2.

Click the Open button in the above figure to log on to the switch. Enter the login user name

and password to log on the switch, and then enter enable to enter Privileged EXEC Mode,
so you can continue to configure the switch.

2.

Note:

The key length is in the range of 512 to 3072 bits.

During the key generation, randomly moving the mouse quickly can accelerate the key

generation.

2.

After the key is successfully generated, please save the public key and private key to a
TFTP server.

Figure 1-8 Save the Generated Key
3.

Log on to the switch by Telnet and download the public key file from the TFTP server to the
switch, as the following figure shows:

Figure 1-9 Download the Public Key

Note:

1.

The key type should accord with the type of the key file.

Click Browse to download the private key file to SSH client software and click Open.

Figure 1-11 Download the Private Key
6.

After successful authentication, please enter the login user name. If you log on to the
switch without entering password, it indicates that the key has been successfully
downloaded.

1.2 CLI Command Modes
The CLI is divided into different command modes: User EXEC Mode, Privileged EXEC Mode,

Global Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode.

10

Interface Configuration Mode can also be divided into Interface Ethernet, Interface
link-aggregation and some other modes, which is shown as the following diagram.

The following table gives detailed information about the Accessing path, Prompt of each mode
and how to exit the current mode and access the next mode.

1.3 Privilege Restrictions
This switch’s security is divided into four privilege levels: User level, Power User level, Operator
level and Admin level. You can define username and password pairs, and assign a specific

privilege level to each pair. Different privilege levels have access to specified commands,

which is illustrated in the Privilege Requirement in each command. For details about how to

configure usename and password pairs, please refer to user name (password) and user name
(secret).

Users can enter Privileged EXEC mode from User EXEC mode by using the enable command. In

Etherchannel Commands

Etherchannel Commands are used to configure LAG and LACP function.
LAG (Link Aggregation Group) is to combine a number of ports together to make a single
high-bandwidth data path, which can highly extend the bandwidth. The bandwidth of the LAG is
the sum of bandwidth of its member port.

LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic

link aggregation and disaggregation by exchanging LACP packets with its partner. The switch
can dynamically group similarly configured ports into a single logical link, which will highly
extend the bandwidth and flexibly balance the load.

no ip dos-prevent type { land | scan-synfin | xma-scan | null-scan |

port-less-1024 | blat | ping-flood | syn-flood | win-nuke | smurf |

ping-of-death }

Parameter
land ——The attacker sends a specific fake SYN (synchronous) packet to the

destination host. Because both of the source IP address and the destination

IP address of the SYN packet are set to be the IP address of the host, the
host will be trapped in an endless circle of building the initial connection.

scan-synfin ——The attacker sends the packet with its SYN field and the FIN

field set to 1. The SYN field is used to request initial connection whereas the

FIN field is used to request disconnection. Therefore, the packet of this type
is illegal.

xma-scan ——The attacker sends the illegal packet with its TCP index, FIN,
URG and PSH field set to 1.

null-scan ——The attacker sends the illegal packet with its TCP index and all
the control fields set to 0. During the TCP connection and data transmission,
the packets with all control fields set to 0 are considered illegal.

port-less-1024 ——The attacker sends the illegal packet with its TCP SYN
field set to 1 and source port smaller than 1024.

blat ——The attacker sends the illegal packet with the same source port and

destination port on Layer 4 and with its URG field set to 1. Similar to the Land
Attack, the system performance of the attacked host is reduced because the
Host circularly attempts to build a connection with the attacker.

ping-flood ——The attacker floods the destination system with Ping packets,

creating a broadcast storm that makes it impossible for the system to
respond to legal communication.

syn-flood ——The attacker uses a fake IP address to send TCP request

packets to the server. Upon receiving the request packets, the server

responds with SYN-ACK packets. Since the IP address is fake, no response
will be returned. The server will keep on sending SYN-ACK packets. If the

attacker sends overflowing fake request packets, the network resource will
be occupied maliciously and the requests of the legal clients will be denied.

win-nuke ——Because the Operation System with bugs cannot correctly
process the URG (Urgent Pointer) of TCP packets, the attacker sends this
type of packets to the TCP port139 (NetBIOS) of the host with the Operation
91

System bugs, which will cause the host with a blue screen.
smurf —— The attacker broadcasts large numbers of Internet Control

Message Protocol (ICMP) packets with the intended victim’s spoofed source
IP to a computer network using an IP broadcast address. Most devices on a

network will respond to this by sending a reply to the source IP address. If the
number of devices on the network that receive and respond to these packets

is very large, the victim’s host will be flooded with traffic, which can slow down
the victim’s host and cause the host impossible to work on.

ping-of-death —— The attacker sends an improperly large Internet Control
Message Protocol (ICMP) echo request packet, or a ping packet, with the

purpose of overflowing the input buffers of the destination host and causing
the host to crash.

Chapter 14 IEEE 802.1X Commands
IEEE 802.1X function is to provide an access control for LAN ports via the authentication. An
802.1X system include three entities: supplicant, authenticator and authentication server.



Supplicant: the device that requests access to the LAN.

Authentication server: performs the actual authentication of the supplicant. It validates the

identity of the supplicant and notifies the authenticator whether or not the supplicant is
authorized to access the LAN.


Authenticator: controls the physical access to the network based on the authentication

status of the supplicant. It is usually an 802.1X-supported network device, such as this

TP-Link switch. It acts as an intermediary (proxy) between the supplicant and the

authentication server, requesting identity information from the supplicant, verifying that
information with the authentication server, and relaying a response to the supplicant.

This chapter handles with the authentication process between the supplicant and the switch.

To realize the authentication and accounting function, you should also enbable the AAA
function and configure the RADIUS server. Go to Chapter 44 AAA Commands for more details.

Port Security. To return to the default configurations, please use no mac

address-table max-mac-count command. Port Security is to protect the

switch from the malicious MAC address attack by limiting the maximum

number of the MAC addresses that can be learned on the port. The port with
Port Security feature enabled will learned the MAC address dynamically.

When the learned MAC address number reaches the maximum, the port will
stop learning. Therefore, the other devices with the MAC address unlearned

Syntax

can not access to the network via this port.

mac address-table max-mac-count { [ max-number num ] [ mode { dynamic |

static | permanent } ] [ status { forward | drop | disable } ] }

the port. It ranges from 0 to 64. By default this value is 64.

dynamic | static | permanent —— Learn mode for MAC addresses. There are
three modes, including Dynamic mode, Static mode and Permanent mode.

When Dynamic mode is selected, the learned MAC address will be deleted

automatically after the aging time. When Static mode is selected, the learned

MAC address will be out of the influence of the aging time and can only be

deleted manually. The learned entries will be cleared after the switch is
rebooted. When permanent mode is selected, the learned MAC address will

be out of the influence of the aging time and can only be deleted manually too.
However, the learned entries will be saved even the switch is rebooted.

status —— Select the action to be taken when the number of the MAC

addresses reaches the maximum learning number on the port. By default this
function is disabled.

When the schedule mode is specified as WRR, the weight value ranges from 1
to 127. The 8 queues will take up the bandwidth according to their ratio. The

default values of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are 1, 2, 4, 8, 16,
32, 64 and 127 respectively.

When the schedule mode is specified as SP+WRR, the weight value ranges

from 0 to 127. TC7 and the queue with its weight value set as 0 are in the SP
group; other queues, with none-zero weight value, belong to the WRR group.

In this SP+WRR scheduling mode, the queues in the SP group is scheduled

preferentially (TC6>TC5>TC4>TC3>TC2>TC1>TC0 in strict priority). When
there is no packets to be sent in the SP group, the queues in the WRR group

will be scheduled according to the weight value of each queue. The default

Chapter 33 AAA Commands
AAA stands for authentication, authorization and accounting. This feature is used to
authenticate users trying to log in to the switch or trying to access the administrative level
privilege.


Applicable Access Application

The authentication can be applied on the following access applications: Telnet, SSH and HTTP.


Authentication Method List

A method list describes the authentication methods and their sequence to authenticate a user.
The switch supports Login List for users to gain access to the switch, and Enable List for
normal users to gain administrative privileges.


RADIUS/TACACS+ Server

User can configure the RADIUS/TACACS+ servers for the connection between the switch and
the server.


Server Group

User can define the authentication server group with up to several servers running the same
secure protocols, either RADIUS or TACACS+. Users can set these servers in a preferable
order, which is called the server group list. When a user tries to access the switch, the switch
will ask the first server in the server group list for authentication. If no response is received, the
second server will be queried, and so on.
