 # 进入特权模式 enable
configure terminal

# 查看设备信息
show version
show inventory

# 配置管理IP(建议使用专用VLAN)
interface vlan 100
ip address 10.1.100.254 255.255.255.0
exit
ip default-gateway 10.1.100.1

# 配置SSH登录(推荐安全协议)
hostname Ruijie-SW
crypto key generate rsa modulus 2048 # 生成密钥
line vty 0 4
login local
transport input ssh
exit
username admin password 8 ruijie@2024 # 密码加密存储

二、VLAN深度配置

2.1 基础VLAN操作

# 批量创建VLAN
vlan range 10,20,30-40

# 配置Access端口
interface gigabitEthernet 0/5
switchport mode access
switchport access vlan 10
storm-control broadcast level 20 # 广播抑制

# 配置Trunk端口(支持QinQ)
interface gigabitEthernet 0/24
switchport mode trunk
switchport trunk allowed vlan 10,20
switchport trunk native vlan 10

2.2 私有VLAN(PVLAN)

1
2
3
4

vlan 500 private-vlan community \# 公共VLAN
vlan 501 private-vlan isolated \# 隔离VLAN
private-vlan association 500 501
interface gigabitEthernet 0/10
switchport mode private-vlan host
switchport private-vlan host-association 500 501 \# 端口隔离

三、安全加固配置

3.1 端口安全(防私接)

1
2
3
4
5
interface gigabitEthernet 0/8
port-security enable
port-security maximum 3
port-security violation restrict # 违规限制
port-security mac-address sticky 0011.2233.4455

3.2 DHCP Snooping防护

1
2
3
4
ip dhcp snooping
ip dhcp snooping vlan 10
interface gigabitEthernet 0/24
ip dhcp snooping trust # 信任上行口

3.3 动态ARP检测(DAI)

1
2
3
ip arp inspection vlan 10
interface gigabitEthernet 0/24
ip arp inspection trust

四、路由协议配置

4.1 静态路由

1
ip route 0.0.0.0 0.0.0.0 192.168.100.1

4.2 OSPF动态路由

1
2
3
router ospf 1
network 10.1.0.0 0.0.255.255 area 0
network 192.168.1.0 0.0.0.255 area 0

4.3 VRRP虚拟路由冗余

1
2
3
4
interface vlan 10
vrrp 1 ip 10.1.10.254
vrrp 1 priority 120 # 主设备优先级
vrrp 1 preempt delay 60 # 抢占延迟

五、QoS流量工程

5.1 流量分类与标记

1
2
3
4
5
6
7
8
class-map match-all VOICE
match dscp ef
policy-map QOS_POLICY
class VOICE
set cos 5
police cir 10000000 # 10M带宽保障
interface gigabitEthernet 0/18
service-policy input QOS_POLICY

5.2 限速策略(基于端口)

1
2
3
interface gigabitEthernet 0/15
rate-limit input 1024000 2048000 # 突发限制
rate-limit output 1024000 2048000

**

六、高级排错命令

6.1 端口诊断

1
2
3
show interfaces status # 端口状态总览
show interfaces counters gigabitEthernet 0/24 # 流量统计
show mac-address-table dynamic vlan 10 # MAC地址追踪

6.2 镜像端口抓包

1
2
monitor session 1 source interface gigabitEthernet 0/5 both # 双向镜像
monitor session 1 destination interface gigabitEthernet 0/1

6.3 日志分析

1
2
show logging | include error # 过滤错误日志
debug ip packet detail # 实时调试(慎用)

七、维护与管理

7.1 配置管理

1
2
copy running-config startup-config # 保存配置
copy startup-config tftp://192.168.1.100/backup.cfg # 备份到TFTP

7.2 固件升级

1
2
3
4
copy tftp://192.168.1.100/RGOS11.4.bin flash: # 下载固件
verify flash:RGOS11.4.bin # 校验文件
boot system flash:RGOS11.4.bin # 设置启动镜像
reload # 重启生效

特别说明‌:不同型号锐捷交换机可能存在命令差异,建议在实验环境中验证后再进行生产环境部署。
