What is the Characteristics of Huawei S2700 Switch?

Easy Operation and Maintenance

Huawei S2700 supports Easy-Operation, which implements easy installation, configuration,
monitoring, and troubleshooting. This technology greatly reduces installation and
configuration costs and engineering costs, and improves upgrade efficiency. The S2700
provides the CLI and web platform, supports alarm management and visualized configuration,
and replacement of faulty devices.
The S2700 uses the ASIC chip and fanless design, which reduces mechanical faults and
protects the equipment against damages caused by condensed water and dusts.

 Flexible Service Control
The S2700 supports various ACLs. ACL rules can be applied to VLANs to flexibly control
traffic on interfaces and schedule resources in VLANs.
The S2700 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 S2700 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, Huawei S2700 supports SSHv2, HWTACACS, RMON,
interface-based traffic statistics, and NQA to help in network planning and upgrading.

Various Security Measures
The S2700 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 S2700 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 S2700
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 S2700 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.

Various Reliability Mechanisms
The S2700 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 S2700 like S2700-28TP-EI also supports enhanced Ethernet reliability
technologies such as Smart Link and RRPP, which implement millisecond-level protection
switching and ensure network reliability.
The S2700 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 S2700 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.

Creating a VLANIF Interface

Creating a VLANIF Interface
VLANIF interfaces are Layer 3 logical interfaces. After creating VLANIF interfaces on Layer 2 devices, you can configure Layer 3 features on these interfaces.

Establishing the Configuration Task

Before creating a VLANIF interface, familiarize yourself with the applicable environment, complete the pre-configuration tasks, and obtain the data required for the configuration. This will help you complete the configuration task quickly and accurately.

Applicable Environment

Layer 3 switching combines routing and switching techniques to implement routing on a switch, thus improving the overall network performance. After sending the first data flow, a Layer 3 switch generates mappings between MAC addresses and IP addresses. To send the same data flow, the switch directly sends the data flow at Layer 2 but not Layer 3 based on this mapping table.
To allow that new data flows are correctly forwarded based on the routing table, be sure that the routing table's routing entries are correct. Therefore, VLANIF interfaces and routing protocols must be configured on Layer 3 switches for reachable Layer 3 routes.

Pre-configuration Tasks

Before creating a VLANIF interface, complete the following task:
· Creating a VLAN

Data Preparation

To create a VLANIF interface, you need to the following data.
No.
Data
1
VLAN ID
2
IP address to be assigned to the VLANIF interface
3
(Optional) Delay after which the VLANIF interface goes Down
4
(Optional) MTU of the VLANIF interface



Creating a VLANIF Interface

Before configure Layer 3 features on a Layer 2 device, you must create a VLANIF interface on the device.

Procedure

1. Run:
system-view
The system view is displayed.
2. Run:
interface vlanif vlan-id
A VLANIF interface is created and the VLAIF interface view is displayed.
The VLAN ID specified in this command must be the ID of an existing VLAN.
 NOTE:
A VLANIF interface is Up only when at least one physical port added to the corresponding VLAN is Up.
Parent

Assigning an IP Address to a VLANIF Interface

As a VLANIF interface is a Layer 3 logical interface, it can communicate with other interfaces at the network layer only after being assigned an IP address.

Procedure

1. Run:
system-view
The system view is displayed.
2. Run:
interface vlanif vlan-id
The VLANIF interface view is displayed.
The VLAN ID specified in this command must be the ID of an existing VLAN.
3. Run:
ip address ip-address { mask | mask-length } [ sub ]
An IP address is assigned to the VLANIF interface for communication at the network layer.

 

Checking the Configuration

After a VLANIF interface is configured for communication at the network layer, you can check the IP address and status of a specified VLANIF interface.

Prerequisites

The configurations of a VLANIF interface are complete.

Procedure

· Run the display interface vlanif  [ vlan-id ] command to check the physical status, link protocol status, description, and IP address of the VLANIF interface.

The Function of Huawei S2700EI Series Switches

The Huawei S2700EI series switch is next-generation energy-saving 100M Ethernet intelligent switches - is deployed at the access layer of a campus network to provide high performance, multi-service, and highly reliable enterprise network.
 
Huawei S2700EI Series Switches Characteristics:
PoE
The S2700EI PWR provides improved PoE solutions. You can configure whether and when a PoE port supplies power. The S2700EI PWR can use PoE power supplies with different power levels to provide -48V DC power for powered devices (PDs), such as IP phones, WLAN APs, and Bluetooth APs. 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.

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.
