How Do I Configure the Telnet Login Function

How Do I Configure the Telnet Login Function?

You can log in to a switch (I use the S2700-26TP-EI-AC most time) through Telnet only when the switch has an IP address and the VTY

user authentication method and VTY user level have been configured. By default, the preceding

configurations are unavailable on the switch, and you must log in to the switch through the

console interface and complete the configurations.

Perform the following configurations:

1. Set a management IP address for the switch.

A # If the switch has an management interface, configure an IP address for the management

interface.

<HUAWEI> system-view

[HUAWEI] interface meth 0/0/1

[HUAWEI-MEth0/0/1] ip address ip address 192.168.1.2 24

[HUAWEI-MEth0/0/1] quit

B # If the switch has no management interface, configure an IP address for the WLANIF

interface.

<HUAWEI> system-view

[HUAWEI] vlan 4094

[HUAWEI-vlan4094] quit

[HUAWEI] interface gigabitethernet 0/0/48

[HUAWEI-GigabitEthernet0/0/48] port link-type hybrid

[HUAWEI-GigabitEthernet0/0/48] port hybrid untagged vlan 4094

[HUAWEI-GigabitEthernet0/0/48] quit

[HUAWEI] interface vlanif 4094

[HUAWEI-Vlanif4094] ip address ip address 192.168.1.2 24

[HUAWEI-Vlanif4094] quit

2. Configure reachable routes between the PC and switch so that the PC can successfully ping

the switch.

A If the PC is directly connected to the switch, ensure that the IP address of the PC is in

the same network segment as the management IP address of the switch.

B If the PC is not directly connected to the switch, configure reachable routes between

the PC and switch.

3. Set the authentication mode for Telnet login to AAA.

[HUAWEI] user-interface vty 0 4

[HUAWEI-ui-vty0-4] authentication-mode aaa

[HUAWEI-ui-vty0-4] quit

4. Configure the Telnet login user parameters. Set the user name and password to admin, and

user level to 3.

[HUAWEI] aaa

[HUAWEI-aaa] local-user admin password cipher admin

[HUAWEI-aaa] local-user admin privilege level 3

[HUAWEI-aaa] local-user admin service-type telnet

Note:

This configuration works for Huawei S2700, Huawei S3700, Huawei S5700 and Huawei S6700.

1 business card

Now, access route not only supports the E1, SA and other wide area net card, and with thedegree of integration and ALL-in-One device concept, the two layer switching card, voice card, PON card and so on have access.

Exchange board 24 Gigabit Ethernet Huawei AR G3 support switching port, friends are shocked!

"Sounded the alarm security prism gate" incident on the network, the cryptographic card(data encryption card) is sometimes necessary

Even the same type of card, manufacturers will access density customized various, different access density board different price, buyers can choose according to needs and their own funds.

The same is to realize the function of E1 AR G3, Huawei can provide 1, 2, 4, 8 ports of theE1 card

The board is unceasingly rich, on the one hand makes the original router business greatly expanded at the same time, but also reduce the number of equipment, simplify the network management. Huawei AR G3 currently has as many as nearly 50 kinds of business cardsare available, including the common E1, SA, Ethernet two / three layer, voice card etc..

2 The board hot swap

The board support hot plug, which was originally proposed to telecom equipment requirements. But now with the enterprises and units of office IT comprehensive popularization, the network caused by interruption losses are increasing, more and more attention to the reliability of equipment.

Therefore, for large and medium enterprises, or router network location where the critical(such as access to the key server), the board support hot plug is essential. When a router on the part of the board in the event of a failure or expansion needs to be replaced, do not needto cut off the power of the equipment, direct online card replacement treatment.

To achieve without power to Huawei AR G3 router, hot swapping business cards.

The above is the access level modular access router needs to pay attention, these factors are also the router vendors in the strength of the most important factors. In addition to the factors mentioned above, simple richness, management and maintenance of software functions and protocols supported by (Web network), whether to support the redundant power supplies, and memory are the factors that need to be considered.

Huawei AR G3 series routers not only in several of the above mentioned showed excellent,relying on Huawei in the telecommunications industry, technology accumulation, theequipment reliability, ease of use and richness of business support are leading the industrylevel, and rich, convenient choice, price is relatively high, is the choice of enterprise access level modular router good.

Huawei Access also is one choice of these.

Today the fixed network has entered an ultra-broadband era featuring abundant video services. Broadband is booming worldwide. As a leader in the global access network market, Huawei’s access products cover three main domains: traditional fixed access (MSAN, DSLAM), fiber broadband access (FTTx), fiber and copper infrastructure (ODN and MDF).

How to Fix Huawei Switch Terminal Garbled Characters

How to Fix Huawei Switch Terminal Garbled Characters, I use the switch S5700S-52P-LI-AC most time daily.

Fault Description

After a terminal connecting to a switch starts, it cannot display anything or displays garbled characters.

Possible Cause

The power module of the switch is faulty or the switch is not powered on.

The serial interface connecting to the switch is incorrectly configured.

The cable between the terminal and switch is faulty or not firmly connected to the serial interface.

Troubleshooting Procedure

1. Check the power indicator on the switch's front panel. If the RUN/ALM indicator is On, the power module is working properly. If the power indicator is Off, rectify the fault according to Power Module Failures.

2. Check whether the parameters of the serial interface are correctly configured.

# Verify that the connection interfaces are configured correctly. Some PCs have multiple serial interfaces and each serial interface has a number. When configuring connection interfaces, you must select the correct connection interface number, as shown in Figure1.

Figure 1 Setting a connection port

# Verify that the physical attributes of the serial interface on the PC are the same as those of the console interface on the device, as shown in Figure 5-2. When the attributes of the console interface on the device are not changed, the details are as follows:

l Baud rate: 9600

l Data bit: 8

l Stop bit: 1

l Parity check: None

l Flow control: None

Figure 2 Setting the parameters of the serial interface on the PC

3. Ensure that the cable is firmly connected to the serial interface. You can replace it with a new cable to verify whether the cable is faulty.
