H3C S5500 划分vlan以及做DHCP
登录5500设备：
[H3C]dhcp server ip-pool vlan30
[H3C-dhcp-pool-vlan30]network 192.168.30.0 mask 255.255.255.0
[H3C-dhcp-pool-vlan30]gateway-list 192.168.30.1
[H3C-dhcp-pool-vlan30]dns-list 202.106.0.20
[H3C-dhcp-pool-vlan30]expired day 8
[H3C]vlan 30 创建vlan30
[H3C]qu
[H3C]interface Vlan-interface 30
[H3C-Vlan-interface30]ip address 192.168.30.1 255.255.255.0
[H3C-Vlan-interface30]dhcp select server global-pool
[H3C-Vlan-interface30]qu
[H3C]dhcp server forbidden-ip 192.168.30.1 192.168.30.100
#192.168.30.1 192.168.30.100之间的IP地址保留，不参与地址自动分配
[H3C]interface range GigabitEthernet 1/0/12 to GigabitEthernet 1/0/14 进入到13 14 15 这三个端口
[H3C-if-range]port access vlan 30 将端口加入到vlan30
[H3C-if-range]dis vlan 30 查看哪些接口加入到vlan30，我们看到 12 13 14 这三个端口已加入到vlan30
VLAN ID: 30
VLAN Type: static
Route Interface: configured
IPv4 address: 192.168.30.1
IPv4 subnet mask: 255.255.255.0
Description: VLAN 0030
Name: VLAN 0030
Tagged Ports: none
Untagged Ports:
GigabitEthernet1/0/12 GigabitEthernet1/0/13 GigabitEthernet1/0/14
在12端口接入一台主机 ping三层网关 ok ping防火墙不通
解决办法：
1、登录H3C-F100-C-G 防火墙
2、网络管理 > 路由管理 > 静态路由 进入到这个目录下面 点新建
3、目的IP地址：192.168.30.0 掩码：255.255.255.0 下一跳：192.168.1.2 这里是三层设备的网关
再次ping防火墙 ping192.168.1.1 ok
