Technical Skill
1. Adjust the font size of the Super Terminal;
2. Capture the Super Terminal command line for future check;
3. Language-Mode
Chinese | switch between English and Chinese;
4. Copy the command to the Super Terminal command line and paste it to the host;
5. Switch clearing configuration: <H3C> Reset
Save; <H3C> Reboot;
6. When configuring vrouters and vswitches, the power cannot be switched off. Before Connectivity testing, you must

Check network connectivity and do not make the lowest-level errors.
7. 192.168.1.1/24 is equivalent to 192.168.1.1
255.255.255.0; When configuring vswitches and vrouters, 192.168.1.1 255.255.255.0 can be written as 192.168.1.1

Common configurations of Huawei switches for small and medium-sized enterprises or large enterprise branches

In branches of small and medium-sized enterprises or large enterprises, L2 Ethernet switches act as L2 aggregation switches, which can be directly connected to users and uplinked to L2/L3 Ethernet switches, you can connect to the network of the headquarters or other branches through a vro.
Each department is divided into one VLAN in the network. To facilitate network management, SNMP must be configured. to prevent unauthorized access to the switch, ACL control must be configured on the switch.
The entire network uses vlan10 as the management VLAN. The IP addresses of vlan10 interfaces on all vswitches are in the same network segment 10.110.110.0/24, the IP address of the master RADIUS server is 10.110.10.18, And the IP address of the network management station is 10.11.10.1. The IP address of the router is 10.100.11.1.
The vlan2 interface is connected to the vro. the IP address of the vlan2 interface is 10.100.11.2.
Configure L2 switches as follows: Manage VLAN configuration, network management route configuration, SNMP configuration, ACL control configuration for various access modes, and hybrid port configuration.
Configure the gateway, hybrid port, SNMP, ACL control for various access methods, and mutual access control between departments on the second/third-layer switch.
This article only describes the basic configurations on the vswitch.
1.
Tch B Configuration
The following uses tch B as an example to describe the basic configuration process. All computers in this department are configured in one VLAN.
(1)
Configure a VLAN.
[Quidway] VLAN 5
[Quidway-vlan5] port ethernet 0/1 to Ethernet 0/24
Ethernet 1, 1/1
[Quidway-vlan5] Quit
(2) configure and manage VLANs and routes.

# Configure the route. The next hop is 10.110.110.1.
[Quidway] IP Route
10.11.10.1 255.255.255.248 10.110.110.1
(3)
Configure the uplink port ethernet1/1 as the hybrid port to allow packets from vlan10 and vlan5 to pass through.

(5)
Configure access control for telnet users. Only users with IP addresses 10.110.110.46 and 10.110.110.52 can access the vswitch through Telnet.
