How to Powering on Huawei S2700&S3700&S5700&S6700 Switch for the First Time?

When you get a new Huawei S2700&S3700&S5700&S6700, do you know how to power it on in the correct way?

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Multimeter
  • Console cable

Procedure
Step 1 Perform the following checks before powering on a switch:
1. Use a multimeter to check that there is no short-circuit condition between the phase wire
(live wire), earth wire, and neutral wire in each power outlet.
2. Use the multimeter to check that the input voltage provided by the external power supply
system is within the operating voltage range for the switch. For the operating voltage
range.
3. Check that the power switches of the external power supply system and the switch or the
power module are both turned off.
4. Check that the power cables are correctly connected.
Step 2 Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that it is in
close contact with your wrist and grounded properly.
Step 3 Connect the DB-9 connector of the console cable to the 9-pin serial port on a maintenance
terminal. Then, connect the RJ45 connector of the console cable to the console port on the
switch.

How to Operate MAC Address Table Configuration?

How to Configure MAC Address Table on Huawei S2300 and S3300 Switch

Networking Requirements
As shown in Figure, the MAC address of the user host PC1 is 0002-0002-0002 and that
of the user host PC2 is 0003-0003-0003. PC1 and PC2 are connected to the Switch through the
LSW. The LSW is connected to Eth0/0/1 of the Switch, which belongs to VLAN 2. The MAC
address of the server is 0004-0004-0004. The server is connected to Eth0/0/2 of the Switch.
Eth0/0/2 belongs to VLAN 2.

  • To prevent hackers from using MAC addresses to attack the network, configure two static MAC address entries for each user host on the Switch.
  • To prevent hackers from stealing user information by forging the MAC address of the server, configure a static MAC address entry on the Switch for the server.



Configuration Roadmap
The configuration roadmap is as follows:
1. Create a VLAN and add an interface to the VLAN to implement Layer 2 forwarding.
2. Configure static MAC address entries to prevent MAC address attacks.
3. Configure the aging time of dynamic MAC address entries to update the entries.

Procedure
Step 1 Configure static MAC address entries.
# Create VLAN 2 and add Ethernet0/0/1 and Ethernet0/0/2 to VLAN 2.
<Switch> system-view
[Switch] vlan 2
[Switch-vlan2] quit
[Switch] interface ethernet 0/0/1
[Switch-Ethernet0/0/1] port hybrid pvid vlan 2
[Switch-Ethernet0/0/1] port hybrid untagged vlan 2
[Switch-Ethernet0/0/1] quit
[Switch] interface ethernet 0/0/2
[Switch-Ethernet0/0/2] port hybrid pvid vlan 2
[Switch-Ethernet0/0/2] port hybrid untagged vlan 2
[Switch-Ethernet0/0/2] quit
# Configure a static MAC address entry.

[Switch] mac-address static 3-3-3 Ethernet 0/0/1 vlan 2
[Switch] mac-address static 4-4-4 Ethernet 0/0/2 vlan 2
Step 2 Set the aging time of a dynamic MAC address entry.
[Switch] mac-address aging-time 500
Step 3 Verify the configuration.
# Run the display mac-address command in any view to check whether the static MAC address
entries are successfully added to the MAC address table.
[Switch] display mac-address static vlan 2

Terminal Does Not Display Anything Or Displays Garbled Characters

Fault Description

After a terminal connecting to the switch S5700S-28P-LI-AC 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 Figure 1.

The Difference Between Layer 2 & Layer 3 Switches

The layer 2 switching and layer 3 switching are the most commonly used switches. This article will tell you a detail of layer 2 switching and layer 3 switching.

The difference between layer 2 & layer 3 switches

A Layer 2 switch does switching only. This means that it uses MAC addresses to switch the packets from a port to the destination port (and only the destination port). It therefore maintains a MAC address table so that it can remember which ports have which MAC address associated.
A Layer 3 switch also does switching exactly like a L2 switch. The L3 means that it has an identity from the L3 layer. Practically this means that a L3 switch is capable of having IP addresses and doing routing. For intra-VLAN communication, it uses the MAC address table. For extra-VLAN communication, it uses the IP routing table.

Layer 2 Switching

A Layer 2 switch works at the second layer of the OSI model and forwards data packets based on media access control (MAC) addresses. Ports on a Layer 2 switch send and receive data independently and belong to different collision domains. Collision domains are isolated at the physical layer so that collisions will not occur between hosts (or networks) connected through this Layer 2 switch due to uneven traffic rates on these hosts (or networks).
This section describes how Layer 2 switching is implemented on an Ethernet network.
A layer 2 switch parses and learns source MAC addresses of Ethernet frames and maintains a mapping table of MAC addresses and ports. This table is called a MAC address table. When receiving an Ethernet frame, the switch searches for the destination MAC address of the frame in the MAC table to determine through which port to forward this frame.
  • When the Layer 2 switch receives an Ethernet frame, it records the source MAC address and the inbound port of the frame in the MAC address table to guide Layer 2 forwarding. If the same MAC address entry exists in the MAC address table, the switch resets the aging time of the entry. An aging mechanism is used to maintain entries in the MAC address table. Entries that are not updated within the aging time are deleted from the MAC address table.
  • The switch looks up the MAC address table based on the destination MAC address of the Ethernet frame. If no matching entry is found, the switch forwards the frame to all its ports except the port that receives the frame. If the destination MAC address of the frame is a broadcast address, the switch forwards the frame to all its ports except the port that receives the frame. If a matching entry is found in the MAC address table, the switch forwards the frame to the port specified in the entry.
According to the preceding forwarding process, a Layer 2 switch maintains a MAC address table and forwards Ethernet frames based on destination MAC addresses. This forwarding mechanism fully uses network bandwidth and improves network performance. The below figure shows an example of Layer 2 switching.
layer-2-switch

Although Layer 2 switches can isolate collision domains, they cannot isolate broadcast domains. As described in the Layer 2 forwarding process, broadcast packets and packets that do not match nay entry in the MAC address table are forwarded to all ports (except the receiving port). Packet broadcasting consumes much bandwidth on network links and brings security issues. Routers can isolate broadcast domains, but high costs and low forwarding performance of routers limit the application of routers in Layer 2 forwarding. The virtual local area network (VLAN) technology is introduced to solve this problem in Layer 2 switching.

Layer 3 Switching

The layer 3 switches divide a Layer 2 network into multiple VLANs. They implement Layer 2 switching within the VLANs and Layer 3 IP connectivity between VLANs. Two hosts on different networks communicate with each other through the following process:
  • Before the source host starts communicating with the destination host, it compares its own IP address with the IP address of the destination host. If IP addresses of the two hosts have the same network ID (calculated by an AND operation between the IP addresses and masks), the hosts are located on the same network segment. In this case, the source host sends an Address Resolution Protocol (ARP) request to the destination host. After receiving an ARP reply from the destination host, the source host obtains the MAC address of the destination host and sends packets to this destination MAC address.
  • If the source and destination hosts are located on different network segments, the source host sends an ARP request to obtain the MAC address mapping the gateway IP address. After receiving an ARP reply from the gateway, the source host sends packets to the MAC address of the gateway. In these packets, the source IP address is the IP address of the source host, and destination IP address is still the IP address of the destination host.

The following is the detailed Layer 3 switching process.
As shown in the below figure, the source and destination hosts connect to the same Layer 3 switch but belong to different VLANs (network segments). Both the two hosts are located on the directly connected network segments of the Layer 3 switch, so the routes to the IP addresses of the hosts are direct routes.
Layer 3 forwarding
layer-3-switch

The above figure shows the MAC addresses, IP addresses, and gateway addresses of the hosts, MAC address of the Layer 3 switch, and IP addresses of Layer 3 interfaces configured in VLANs on the Layer 3 switch. The process of a ping from PC A to PC B is as follows (the Layer 3 switch has not created any MAC address entry):
1. PC A finds that the destination IP address 2.1.1.2 (PC B) is on a different network segment than its own IP address. Therefore, PC A sends an ARP request to request for the MACaddress mapping the gateway address 1.1.1.1.
2. L3 Switch receives the ARP request from PC A and finds that 1.1.1.1 is the IP address of its own Layer 3 interface. L3 switch then sends an ARP reply to PC A. The ARP reply carries the MAC address of its Layer 3 interface (MAC Switch). In addition, L3 switch adds the mapping between the IP address and MAC address of PC A (1.1.1.2 and MAC A) to its ARP table. The IP address and MAC address of PC A are carried in the ARP request sent from PC A.
3. After PC A receives the ARP reply from the gateway (L3 Switch), it sends an ICMP request packet. In the ICMP request packet, the destination MAC address (DMAC) is MAC Switch; the source MAC address (SMAC) is MAC A; the source IP address (SIP) is 1.1.1.2; the destination IP address (DIP) is 2.1.1.2.
4. When L3 Switch receives the ICMP request packet, it updates the matching MAC address entry according to the source MAC address and VLAN ID of the packet. Then L3 Switch looks up the MAC address table according to the destination MAC address and VLAN ID of the packet and finds the entry with the MAC address of its Layer 3 interface, the packet needs to be forwarded at Layer 3. Then L3 Switch looks up Layer 3 forwarding entries of the switching chip to guide Layer 3 forwarding.
5. The switching chip loops up Layer 3 forwarding entries according to the destination IP address of the packet. The entry lookup fails because no entry has been created. The switching chip then sends the packet to the CPU for software processing.
6. The CPU looks up the software routing table according to the destination IP address of the packet and finds a directly connected network segment, network segment of PC B. Then the CPU looks up its ARP table, and the lookup still fails. Therefore, L3 Switch sends an ARP request to all ports in VLAN 3 (network segment of PC B), to request the MAC address mapping IP address 2.1.1.2.
7. After PC B receives the ARP request from L3 Switch, it checks the ARP request and finds that 2.1.1.2 is its own IP address. PC B then sends an ARP reply carrying its MAC address (MAC B). Meanwhile, PC B records the mapping between the IP address and MAC address of L3 Switch (2.1.1.1 and MAC Switch) in its ARP table.
8. When L3 Switch receives the ARP reply from PC B, it records the mapping between the IP address and MAC address of PC B (2.1.1.2 and MAC B) in its ARP table. L3 Switch changes the destination MAC address in the ICMP request packet sent from PC A to MAC B and changes the source MAC address to its own MAC address (MAC Switch), and then sends the ICMP request to PC B. The Layer 3 forwarding entry containing the IP address and MAC address of PC B, outbound VLAN ID, and outbound port is also added to the Layer 3 forwarding of the switching chip. Subsequent packets sent from PC A to PC B are directly forwarded according to this hardware entry.
9. When PC B receives the ICMP request packet from L3 Switch, it sends an ICMP reply packet to PC A. The forwarding process for the ICMP reply packet is similar to that for the ICMP request packet except that the ICMP reply packet is directly forwarded to PC A by the switching chip according to the hardware entry. The reason is that L3 Switch has obtained the mapping between the IP address and MAC address of PC A and added matching Layer 3 forwarding entry to the L3 forwarding table of the switching chip.
10. Subsequent packets exchanged between PC A and PC B are forwarded following the same process: MAC address table lookup, Layer 3 forwarding table lookup, and hardware forwarding by the switching chip.
In a summary, a Layer 3 switch provides high-speed Layer 3 switching through one routing process (forwarding the first packet to the CPU and creating a hardware Layer 3 forwarding entry) and multiple switching processes (hardware forwarding of subsequent packets).

Basic Configuration on the Device at First Login for Huawei Switches

Huawei Switches Basic Configuration:  How to first login the device on console port or mini USB port.
Here, we will describe how to configure the time and date, device name, management IP address, and the user level and authentication mode for Telnet users at first login through the console port or mini USB port. This configuration apply to all the Huawei switches, such as the popular switch: Huawei S5700,S3700S2700

Procedure


1 Set the time and date on the device.

Run:
system-view
The system view is displayed.

Run:
clock timezone time-zone-name { add | minus } offset
The time zone is set.

By default, the system uses the Coordinated Universal Time (UTC) time zone.
add: adds the specified time zone offset to the UTC. That is, the sum of the default UTC time zone and offset equals the time zone specified by time-zone-name.
minus: subtracts the specified time zone offset from the UTC. That is, the remainder obtained by subtracting offset from the default UTC time zone equals the time zone specified by time-zone-name.

Run:
quit
Return to the system view.

Run:
clock datetime HH:MM:SS YYYY-MM-DD
The current time and date are set.
If the time zone is not set, the time set using this command is considered as the UTC time. Before setting the current time, you are advised to confirm the current zone and set the correct time zone offset.

Run:
system-view
The system view is displayed.

Run:
clock daylight-saving-time time-zone-name one-year start-time start-date end-time end-date offset
Or clock daylight-saving-time time-zone-name repeating start-time { { first | second | third | fourth | last } weekday month | start-date1 } end-time { { first | second | third | fourth | last } weekday month | end-date1 } offset [ start-year [ end-year ] ]
Daylight saving time (DST) is set.
By default, DST is not configured.

NOTE:
If you configure periodic DST, the combination of the DST start time and end time can be any of the following: date+date, day of the week+day of the week, date+day of the week, and day of the week+date.
When DST is used, you can run the clock timezone time-zone-name { add | minus } offset command to set the time zone. The time zone in the output of the display clock command is, however, the name of the DST time zone. When DST ends, the system displays the original time zone.

2, Set the device name and management IP address.

Run:
sysname host-name
The device name is set.
By default, the device name is HUAWEI.
When the network management tool needs to obtain the network element (NE) name of a device, you can run the sys-netid command to set an NE name for the device.

Run:
interface interface-type interface-number
The interface view is displayed.
In addition to the management interface on the device, you can also assign the management IP address to Layer 3 interfaces such as VLANIF interfaces on the device.

Run:
ip address ip-address { mask | mask-length }
The management IP address is assigned.
NOTE:
The management IP address is used to maintain and manage the device. Configure the IP address and routes based on the network plan to ensure that the routes between the terminal and device are reachable.

3 Set the user level and authentication mode for Telnet users.

Run:
telnet [ ipv6 ] server enable
The Telnet server is enabled.
By default, the Telnet server is disabled.

Run:
user-interface vty first-ui-number [ last-ui-number ]
The VTY user interface view is displayed.

Run:
protocol inbound { all | telnet }
he VTY user interface is configured to support the Telnet protocol.
By default, a VTY user interface supports the SSH protocol.

Run:
user privilege level level
The Telnet user level is set.
By default, users who log in through the VTY user interface can access commands at level 0.

Run:
authentication-mode aaa
The authentication mode for Telnet users is set to AAA authentication.
By default, no authentication mode is configured for the VTY user interface.
NOTE:
The system provides three authentication modes: AAA authentication, password authentication, and non-authentication modes. AAA authentication requires both the user name and password, and is therefore more secure than password authentication. Non-authentication mode is not recommended because it cannot ensure system security. This section describes how to configure AAA authentication..

Run:
aaa
The AAA view is displayed.

Run:
local-user user-name password irreversible-cipher password
The user name and password for login through Telnet are configured.
The value of password can be a plain-text string of 8 to 128 characters or a cipher-text string of 68 characters.
A too simple password may cause a potential security risk. To enhance the security strength, the password entered in plain text must contain at least two of the following: uppercase letters, lowercase letters, digits, and special characters. In addition, the password cannot be the same as the user name or the mirror user name.

Run:
local-user user-name service-type telnet
The login mode is set to Telnet.

4, Save the configuration.

After basic configuration is complete, you are advised to save the configuration. If the configuration is lost, the connection and configuration for the first login must be performed again.

Run:
return
Return to the user view.

Run:
save
The configuration is saved.
