# 1. 改名(定位设备关键!)system-viewsysname Floor3-SW# 2. 管理IP(华三需先创建VLAN)vlan batch 100interface vlanif 100ip address 192.168.100.10 24# 3. 开启SSH(华三命令:ssh server enable)stelnet serverenableuser-interface vty 0 4authentication-mode aaaprotocol inbound ssh# 4. 保存配置(华三:save force)quitsave

# 1. 关闭死亡服务(通用)undo telnet server # 华为undo ip http server # 华三# 2. 密码策略(华三类似)aaalocal-user admin password irreversible-cipher [email protected]local-user admin service-type ssh# 3. 端口安全(防私接)interface gigabitethernet 0/0/1port-securityenableport-security max-mac-num 3 # 允许3个MAC



# 1. 创建VLANvlan 10name Office# 2. 端口划入VLANinterface gigabitethernet 1/0/5port link-type access # 接入模式port access vlan 10# 3. Trunk口配置(上联核心)interface gigabitethernet 1/0/48port link-type trunkport trunk permit vlan 10 20 # 允许多个VLAN

🆘电脑无法上网

救命命令:
display interface gigabitethernet 1/0/10 # 查看端口状态display mac-address | include 5489-98d3 # 根据MAC定位端口
🆘配置丢失
# 华为恢复配置startup saved-configuration backup.cfg # 指定备份文件reboot# 华三恢复配置(特权模式)<H3C> restore flash:/config.cfg<H3C> reboot

✅命名规范
# 位置-型号-名称-机柜sysname CQBB-S5700-HXSW-A01
✅端口描述
interface gigabitethernet 1/0/23description To_HR_PC-001 # 华三命令相同
✅自动备份
