Does Huawei S3700 Support Port Mirroring?

Huawie S3700 supports port mirroring. The details are as follows:

A maximum of four observing ports can be configured on an S3700. Packets from
multiple ports can be mirrored to the same observing port. You can mirror incoming
packets, outgoing packets, or both to an observing port.



The S3700 supports Remote Switched Port Analyzer (RSPAN). That is, the observing
port and mirrored port can be located on different switches. This facilitates remote
device management.


The S3700 such as S3700-52P-EI-48S-AC supports traffic mirroring. A maximum of four observing ports can be configured on an S3700. Flows can be mirrored from multiple ports to the same
observing port. Flows to be mirrored are determined by the traffic classification rule.

Some FAQs about Huawei S2700 S3700 S5700 S6700 Switch

Many engineer always confused Huawei switch when configuration and management, below are FAQs about Huawei S2700 S3700 S5700 S6700 Switch,

 What Are the Functions of PIM Silent on a PIM Interface?

On the access layer, if the interface directly connected to a host is enabled with the PIM
protocol, PIM neighbors can be established on this interface to process various PIM protocol
packets. Such configuration, however, may bring security problems. For example, when
malicious hosts send a large number of pseudo PIM Hello packets, it may lead to the collapse
of the device.
To avoid the preceding problem, you can run the pim silent command on the interface to set
the interface to work in PIM silent state. After the interface enters the PIM silent state, it is
forbidden to receive or forward any PIM protocol packet. All PIM neighbors and the PIM
state machine on this interface are deleted and the interface automatically becomes a DR.
Meanwhile, the PIM silent function does not affect the IGMP function on the interface.
The PIM silent function is applicable only to the interface that is directly connected to the
network segment of user hosts, and only one PIM device can be connected to this network
segment.

When a Host Leaves a Group, How Does an IGMP Querier Judge Whether Any Other Members of the Group Exist on the Network Segment?

In IGMPv1, when a host leaves a multicast group, the host does not send any message. A
device considers that all multicast members have left a group when the timer of the group
expires.
In IGMPv2 and IGMPv3, a host sends a Leave message when leaving a group. After
receiving the Leave message, the querier sends a group-specific or source/group-specific
Query message to the network segment of the host. The destination address of the Query
message is the address of the multicast group and the group address in the message is also
filled in with the address of the multicast group.
If other members of the group exist on the network segment, they respond with Report
messages.
If no response is received when the timeout period ends, the querier considers that no
member of the group exists on the network segment and cancels forwarding multicast

data to the group.

Can the Hosts and Devices on the Same User Network Segment Run Different Versions of IGMP?

IGMP has three versions, namely IGMPv1, IGMPv2, and IGMPv3. Different IGMP versions
run on devices and hosts are compatible, but all the devices on the same network segment
must run IGMP of the same version. If the versions of IGMP run on the devices on the same
network segment are different, IGMP member relationships are chaotic.
Run the display igmp interface interface-type interface-number command on all the devices
on the same network segment to check the versions of IGMP run on the devices. If the
versions are not the same, modify the configuration.

Other questions about Huawei switch will be posted continually.

The Characteristics of Huawei S3700

The S3700 switch (S3700 for short) is an enterprise networks access device that provides access and data transport functions. The S3700 is developed by Huawei to meet the requirements for reliable access, aggregation, and high-quality transmission of multiple services on an enterprise networks. The S3700 functions as the access device of the enterprise networks. The S3700 provides large capacity, high port density, and cost-effective packet forwarding capabilities. The S3700 also provides multi-service access capabilities, excellent extensibility, quality of service (QoS) guarantee, powerful multicast replication, and carrier-class security, and can be used to build high-reliability ring topologies.

Huawei S3700 Characteristics

Energy-Saving Design
The S3700 saves energy in the following ways:
l Some models adopt natural heat dissipation, so fans are not required.Natural heat
dissipation has the following advantages:
– Product reliability is high.
– There is no noise pollution.
– Fans do not need to be maintained periodically, which saves the maintenance cost.
– The system does not have additional power consumption generated by fans, which
improves the power efficiency.
–        Boards are prevented from being eroded.
NOTE
Currently, the S3700-28TP-EI-MC-AC, S3700-28TP-SI-AC, S3700-28TP-SI-DC, S3700-28TP-EI-AC, and S3700-28TP-EI-DC adopt natural heat dissipation.
l The interface chip switches to the power saving mode when an interface is idle, which
means that no peer device is connected to the interface.
l It uses advanced highly-integrated and energy-saving chips. With the help of the intelligent device management system, the chips improve system performance and also reduce system power consumption.

Advanced Surge Protection Technique
The S3700 uses the Huawei patented built-in surge protection technique. This technique protects devices against lightning in terrible weather and increases device security.
Convenient PoE Power Supply
The S3700 PoE model has the Power over Ethernet (PoE) function. It provides centralized power supply for IP phones, wireless access points (APs), portable device chargers, POS machines, cameras, and data collectors by using twisted pairs.
Complying with IEEE 802.3af and IEEE 802.3at, the S3700 PoE model is able to remotely
provide power for the devices of different vendors. IEEE 802.3at delivers a maximum of 30 W power. This allows IEEE 802.3at to support IP video phones, dualband WiFi APs, IP cameras, multi-function STBs, and RFIDs, and simplifies the network.
The S3700 PoE model has the ability to control power supply based on time range, which
effectively manages network devices, reduces power consumption, and lowers the OPEX.
Note:
The S3700 series Ethernet switches are class A products. Customers should take preventative measures as the operating devices may cause radio interference.

Huawei S3700: DHCP Feature and Stacking Rules

DHCP Feature of Huawei S3700:
DHCP Client and DHCP Server
DHCP adopts the client/server mode, that is, the DHCP client sends request messages to the DHCP server. Then, the DHCP server returns the reply messages according to the address pool policy.
The DHCP server assigns an IP address to the client by using an address pool. When the client sends a DHCP request to the server, the DHCP server selects a proper address pool, finds an idle IP address from the pool, and delivers the IP address along with other related parameters, such as the gateway address, the DNS address and the address lease, to the client.
To dynamically allocate IP addresses to clients, you need to first configure the address pool range on the DHCP server. Currently, an address pool can be configured with only one address range and the address range is determined by the mask length.
DHCP Snooping
The S3700 can be deployed between the DHCP server and the DHCP client and it monitors the DHCP messages between the DHCP server and the DHCP client. The S3700 creates the IP +MAC+PORT+VLAN binding table according to the monitoring result to filter out invalid packets.
The S3700 also supports Option 82.
l After receiving a Request message from the DHCP client, the S3700 appends the Option
82 field to the Request message. The DHCP server enforces the IP address allocation policy according to the Option 82 field.
l The DHCP server appends the Option 82 field to a Response message. The S3700 analyzes the Option 82 field, determines a forwarding interface, removes the Option 82 field, and then forwards the message to a user.
Option 82 can be implemented in two modes on the S3700, Option 82 insert and Option 82 rebuild.
The Option 82 field contains the user circuit IDs. The user circuit IDs include user device name, outer VLAN ID, inner VLAN ID and port number etc. This can effectively prevent attackers from modifying the DHCP messages.

DHCP Relay
The DHCP client and the DHCP server send broadcast packets during the allocation of IP
addresses. Therefore, DHCP can be applied only when the DHCP client and DHCP server are in the same subnet. It is a waste of resource to deploy a DHCP server in each network segment.
The DHCP relay is introduced to solve this problem. Through DHCP relay, a DHCP client in a subnet can communicate with the DHCP server in another subnet and finally obtains an IP address. In this manner, the DHCP clients on different network segments can use the same DHCP server. This reduces costs and achieves centralized management.

Stacking means that the switches located in the same place are connected through the stacking cable or high-speed uplink interfaces, and thus the switches form a reliable switch group. In as switch group, the S3700s are connected through the stack interfaces multiplexed with uplink GE interfaces. Through stacking, the user can manage and maintain the switches uniformly; therefore, the stacking reduces the maintenance cost of the user.The stacked switches must be of the same type.
The stacked switches have three roles:
l Master switch
A stack has only one master switch. The master switch manages the entire stack system by assigning stack IDs to member switches, collecting information about the stack topology, and notifying all the member switches of the information.
l Backup switch
As the backup of the master switch, the backup switch becomes the master if the master
switch is faulty and takes over the work of the master switch.
l Slave switch
A slave switch only processes service traffic on the network and is managed by the master switch.

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.

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 2. When the attributes of the console interface on the device are not changed, the details are as follows:
  • Baud rate: 9600
  • Data bit: 8
  • Stop bit: 1
  • Parity check: None
  • Flow control: None

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).
