H3C核心交换机配置
H3C核心交换机配置H3C每年将销售额的15%以上用于研发投入，在中国的北京、杭州和深圳设有研发机构，在北京和杭州设有可靠性试验室以及产品鉴定测试中心。以下是我整理的关于H3C核心交换机配置，希望大家认真阅读!
1、核心交换机新建用户admin密码admin@h3c，并关联远程登录服务，如telnet web网页登录、ssh远程登录。并开启telnet、web登录服务、ftp服务
#
local-user admin
password cipher admin@h3c
authorization-attribute level 3
service-type telnet
service-type ftp
service-type web
#
telnet server enable
#
ip http enable
#
user-interface vty 0 15
authentication-mode scheme
2、如需新增vlan网段，先新建对应vlan，新建网关、把网线口加入到此vlan，这里例举新增vlan11，网关172.30.162.1/24,把0/0/27-0/0/28口添加到vlan162
#
vlan 162
port GigabitEthernet 0/0/27 to GigabitEthernet 0/0/28
#
interface Vlan-interface162
ip address 172.30.162.1 255.255.255.0
3、开启DHCP自动获取功能，此功能一般只需要在核心交换机上开启，比如这里开启vlan162网段的DHCP功能，并禁止分配172.30.162.1-100
#
dhcp server ip-pool 162
network 172.30.162.0 mask 255.255.255.0
gateway-list 172.30.162.1
dns-list 88.0.0.216 88.0.0.218
#
dhcp enable
#
dhcp server forbidden-ip 172.30.162.1 172.30.162.100
关闭192.168.11.0网段的'DHCP自动获取功能
#
undo dhcp server ip-pool 11
4、下联交换机口必须配置成trunk口，并允许所有vlan通过，比如2槽位板卡，开启trunk配置，这里例举2/0/1和2/0/2口要下接接入交换机
#
interface GigabitEthernet2/0/1
port link-type trunk
port trunk permit vlan 10 20 30 40 50 80 162 500 1000
#
interface GigabitEthernet2/0/2
port link-type trunk
port trunk permit vlan 10 20 30 40 50 80 162 500 1000
5、查看交换机端口使用情况，可查看端口激活状态up或者DOWN，端口工作速率，端口模式，端口对应的vlan号

Protocol: (s) - spoofing
Interface Link Protocol Main IP Description

Vlan1102 UP UP 11.1.1.6 TO-CISCO-11.1.1.5
The brief information of interface(s) under bridge mode:

GE0/0/2 DOWN auto A T 1
GE0/0/3 DOWN auto A T 1
6、查看各个vlan所有在线电脑ip，可通过命令查看在线ip地址-mac地址-学习来源(所接端口)，下面列举查看管理vlan 1000网段交换机在线情况，可以看到下列ip的交换机都在正常工作，都在线
dis arp vlan 1000
