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.

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.

As the power sourcing equipment (PSE), the S2700EI PWR complies with IEEE 802.3af and 802.3at (PoE+) and can supply power to non-standard PDs. PoE ports can work in power-saving mode. Each 802.3at-enabled interface can provide 30 W power, so the S2700EI can connect to high-power terminals.

Various Reliability Mechanisms

The S2700EI supports iStack, which virtualizes multiple switches into one logical switch. iStack improves the switching capacity and enhances reliability and scalability. The stacked switches are managed using a single IP address, which greatly reduces system operation and maintenance costs.

Besides STP, RSTP, and MSTP, the S2700EI also supports enhanced Ethernet reliability technologies such as Smart Link and RRPP, which implement millisecond-level protection switching and ensure network reliability.

The S2700EI supports the Smart Ethernet Protection (SEP) protocol, which is a ring network protocol applied to the link layer of an Ethernet network. SEP provides fast switchover within several milliseconds without interrupting services. SEP features simplicity, high reliability, high switchover performance, convenient maintenance, and flexible topology and enables users to manage and plan networks conveniently.

The S2700EI supports G.8032, also called Ethernet Ring Protection Switch (ERPS). ERPS is based on traditional Ethernet MAC and bridging functions. It uses the mature Ethernet OAM and Ring Automatic Protection Switching (Ring APS or R-APS) technologies to implement fast protection switching on Ethernet. ERPS supports multiple services and provides flexible networking, reducing the OPEX and CAPEX.

Flexible Service Control

The S2700EI supports various ACLs. ACL rules can be applied to VLANs to flexibly control traffic on interfaces and schedule resources in VLANs.

The S2700EI supports VLAN assignment based on interfaces, MAC addresses, protocols, and IP subnets. It applies to networks where users move frequently and networks demanding high security.

The S2700EI supports GVRP, which dynamically distributes, registers, and propagates VLAN attributes to reduce the manual configuration workloads of network administrators and ensure correct VLAN configuration. In addition, the S2700EI supports SSHv2, HWTACACS, RMON, interface-based traffic statistics, and NQA to help in network planning and upgrading.

Various Security Measures

The S2700EI supports DHCP snooping, which generates user binding entries based on MAC addresses, IP addresses, IP address leases, VLAN IDs, and interface numbers of users. The DHCP snooping function protects networks against common attacks such as bogus IP packet attacks, man-in-the-middle attacks, and bogus DHCP server attacks.

The S2700EI can limit the number of MAC addresses learned on an interface to prevent packet flooding that occurs when an attacker frequently changes source MAC addresses.

The S2700EI supports strict ARP learning. This feature prevents ARP spoofing attackers from exhausting ARP entries so that users can connect to the Internet normally. It provides IP source check to prevent DoS attacks caused by IP address spoofing.

The S2700EI supports centralized MAC address authentication and 802.1x authentication. It authenticates users based on static or dynamic user binding information such as the user name, IP address, MAC address, VLAN ID, and interface number. VLANs and ACLs can be applied to users dynamically.

Comprehensive QoS Policies

The S2700EI supports complex traffic classification based on VLAN IDs, MAC addresses, IP protocols, source addresses, destination addresses, priorities, or TCP or UDP port numbers of packets. By limiting the traffic rate based on flows, the S2700EI implements line-speed forwarding on each interface to ensure high quality of the voice, video, and data services. Each interface supports eight queues and multiple queue scheduling algorithms such as WRR, SP, and WRR+SP.

Powerful Surge Protection Capability

The S2700 adopts a Huawei patented surge protection technique to prevent lightning induced overvoltage. All interfaces of the S2700 have a surge protection capability of 6 kV. The Huawei patented surge protection technique greatly reduces the possibility of lightning damages on the equipment even in atrocious environments or in scenarios where grounding cannot be implemented.
