Example for Configuring Communication Between VLANs Using VLANIF Interfaces

Huawei AR150&160&200&1200&2200&3200 Series Enterprise Routers Configuration Guide - Example for Configuring Communication Between VLANs Using VLANIF Interfaces
 
Networking Requirements
As shown in Figure 1, Ethernet 2/0/1 of the Router is connected to the uplink interface of SwitchA.
On SwitchA, the downlink interface Ethernet 2/0/1 is added to VLAN 10 and the downlink interface Ethernet 2/0/2 is added to VLAN 20.
PC1 in VLAN 10 and PC2 in VLAN 20 need to communicate with each other

Configuration Roadmap
The configuration roadmap is as follows:
1. Add Ethernet interfaces to the VLAN.
2. Configure VLANIF interfaces.
 
Procedure
Step 1 Configure the Router.
# Create VLANs.

Application of Huawei S5700

Application of the S5700 on a Large-scale Enterprise Campus Network

As shown in Figure 1, the S5700 Huawei is deployed at the access layer of a campus network to
provide high performance, multi-service, and highly reliable enterprise network.
Figure 1 Position of the S5700 on a Large-scale enterprise campus network
The S5700 provides various terminal security management features, and supports functions such as PoE, voice VLAN, and QoS. The S5700 can be used for desktop access and provides GE access.

 
The S5700 provides various security features including ARP security, IP security, IP source guard, and user access control policies such as NAC and ACLs, to control access of user terminals.
 
The S5700 provides Easy-Operation and USB-based deployment, which facilitates deployment and management.

Example for Prohibiting External Users from Accessing the Web Platform

Applicability
This example applies to all huawei router of V200R002C01 and later versions.
Networking Requirements
GE1/0/0 of RouterA connects to HostA. The hosts in the network segment 10.1.1.0/24 need to be allowed to access device of the web platform and the hosts in other network segments need to be prohibited from accessing the devices the web platform.
Figure 1 Networking diagram of accessing the web platform

Procedure
Configure RouterA.
#
http acl 2000
http server enable
acl number 2000     //Configure an ACL to permit packets from devices of the web platform.
  rule 1 permit source 10.1.1.0 0.0.0.255
  rule 10 deny

Example for Configuring Local Attack Defense

Example for configuring local attack defense for Huawei routers to all versions.

Networking Requirements
As shown in Figure 1, users on different LANs access the Internet through Router A. To locate attacks on Router A, attack source tracing needs to be configured to trace the attack source. The following situations occur:

  • A user on network segment Net1 frequently initiates attacks to Router A.
  • The attacker sends a large number of ARP Request packets, degrading CPU performance.
  • The administrator needs to upload files to Router A using FTP. However, no FTP connection has been set up between the administrator's host and Router A.
  • Most LAN users obtain IP addresses through DHCP, whereas Router A does not first process DHCP client packets sent to the CPU.

Hardware Management(3)- Configuring the Fan Speed

Huawei 3G router AR150&200 &AR1200&2200&3200 Series Enterprise Routers Configuration GuideHardware Management - a proper fan speed ensures stable device operation.
 
Context
The fan speed affects the device temperature. When the device temperature is high, increase the fan speed to lower the device temperature. When the device temperature is low, reduce the fan speed to save energy.
 
NOTE
By default, fans run in automatic mode. In this mode, the system adjusts the fan speed when detecting that the board temperature increases or decreases. The automatic mode reduces noises and saves energy without affecting system running. Therefore, exercise caution when setting the fan speed.
The AR151&200 series does not support this function.
 
Procedure
Step 1 (Optional) Run:
display temperature { all | slot slot-id }
