华为交换机常用命令

2026 年视角：华为 CloudEngine 系列已占国内政企市场大头。命令行沿袭 VRP，旧命令在 99% 的新设备上仍兼容，但建议新配置走 NETCONF/YANG 自动化。

视图切换

<Huawei> system-view              # 进入系统视图
[Huawei] sysname SW-A            # 改主机名
[Huawei] quit                    # 退到用户视图
<Huawei> save                    # 保存配置
<Huawei> reboot                  # 重启

配置文件

# 查看当前配置
[Huawei] display current-configuration

# 清空
<Huawei> reset saved-configuration
<Huawei> reboot

# 备份到 TFTP
<Huawei> tftp 192.168.1.10 put vrpcfg.zip

VLAN

[Huawei] vlan 10
[Huawei-vlan10] description HR

# 批量
[Huawei] vlan batch 10 to 20 30

# 删 VLAN

Access 端口

[Huawei] interface GigabitEthernet0/0/1
[Huawei-GigabitEthernet0/0/1] port link-type access
[Huawei-GigabitEthernet0/0/1] port default vlan 10

Trunk 端口

[Huawei] interface GigabitEthernet0/0/1
[Huawei-GigabitEthernet0/0/1] port link-type trunk

[Huawei-GigabitEthernet0/0/1] port trunk pvid vlan 10

三层 VLANIF

[Huawei] interface Vlanif 10
[Huawei-Vlanif10] ip address 192.168.10.1 24
[Huawei-Vlanif10] display this

端口属性

[Huawei-GigabitEthernet0/0/1] duplex {full | half | auto}
[Huawei-GigabitEthernet0/0/1] speed {10 | 100 | 1000 | auto}
[Huawei-GigabitEthernet0/0/1] flow-control
[Huawei-GigabitEthernet0/0/1] shutdown          # 关
[Huawei-GigabitEthernet0/0/1] undo shutdown    # 开

远程管理

# Telnet
[Huawei] user-interface vty 0 4
[Huawei-ui-vty0-4] protocol inbound telnet
[Huawei-ui-vty0-4] authentication-mode password
[Huawei-ui-vty0-4] set authentication password simple admin123
[Huawei-ui-vty0-4] user privilege level 15

# SSH（生产首选）
[Huawei] stelnet server enable
[Huawei] ssh user admin
[Huawei] ssh user admin authentication-type password
[Huawei] ssh user admin service-type all

查看命令

display version                    # 设备型号 / 启动时间
display cpu-usage                  # CPU
display memory-usage               # 内存
display interface brief           # 端口概要
display vlan                       # VLAN
display mac-address                # MAC 表
display ip routing-table           # 路由表
display arp                        # ARP
display logbuffer                  # 系统日志
display current-configuration      # 当前配置

配置保存

<Huawei> save
The current configuration will be written to the device.
Are you sure to continue?[Y/N]: y

一些经验

  • display this 看当前路径下的配置
  • undo 是华为"反命令"，配错了能 undo 掉
  • 批量改端口用 port-group，比逐个 interface 高效
  • 关键变更前 save 一次，并备份到 TFTP
  • 生产推荐 SSH + AAA 认证，关掉 Telnet
