华三通信安全产品线专注于网络安全以及应用安全,为用户提供融合网络和应用的产品与解决方案。下面是关于H3C交换机vlan简单配置,希望大家认真阅读!
进入系统视图
vlan 10
display vlan all
port e0/1 to e0/2
quit
vlan 20
port e0/3 to e0/4
quit
vlan 30
port e0/1 to e0/4
此时缺省一个端口只属于一个vlan,需要修改e0/1--e0/4的端口模式为混杂模式,一个端口可属于多个vlan有多个vlanid 但只能有一个pvid
interface e0/1
port link-type hybrid(混杂模式)
port hybrid vlan 10 30 untagged
port hybrid pvid vlan 10 修改端口的\'pvid
quit
interface e0/2
port link-type hybrid(混杂模式)
port hybrid vlan 10 30 untagged
port hybrid pvid vlan 10
quit
interface e0/3
port link-type hybrid(混杂模式)
port hybrid vlan 20 30 untagged
port hybrid pvid vlan 20
quit
interface e0/4
port link-type hybrid(混杂模式)
port hybrid vlan 20 30 untagged
port hybrid pvid vlan 20
quit
interface e0/9
port link-type hybrid(混杂模式)
port hybrid vlan 10 20 30 untagged
port hybrid pvid vlan 30
quit
;vlan 10 1 2 9
;vlan 20 3 4 9
;vlan 30 1 2 3 4 9 vlanid配置完成,此时需要确定pvid 是否正确
display interface e 0/1 ; 查看端口信息中的缺省pvid项
端口untagged 的目的是如果9口接不支持标记的设备如单台服务器的网卡,则不通信,如果9口接上级交换则也可tagged。
;不同vlan间的通信简单配置(三种方式)
不同vlan间的通信简单配置
1.单臂路由(图)
环境:一台路由器,一台二层交换机,两台pc机
二层交换机的配置
一般模式:
Switch>
输入enable进入特权模式:
Switch>enable
输入configure terminal进入全局配置模式:
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
创建vlan 10 和 vlan 20:
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)# exit
进入接口配置模式:
Switch(config)#interface fastEthernet 0/1
把0/1变成trunk口(默认是access口)
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
Switch(config-if)#exit
进入接口配置模式分别把对应的接口,加入对应的vlan:
Switch(config)#interface fastEthernet 1/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#interface fastEthernet 2/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
到此而层交换机配置完毕!
路由器的配置:
Router>
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#inter fas 0/0
Router(config-if)#no ip address
Router(config-if)#no shutdown
注意:单臂路由的配置父接口一定要no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exit
Router(config)#int fas 0/0.10
%LINK-5-CHANGED: Interface FastEthernet0/0.10, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.10, changed state to up
Router(config-subif)#encapsulation dot1Q 10
注意:在配置ip时一定要先封装802.1q协议
Router(config-subif)#ip address 192.168.10.1 255.255.255.0
Router(config-subif)#no shutdown
Router(config-subif)#int fas 0/0.20
%LINK-5-CHANGED: Interface FastEthernet0/0.20, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.20, changed state to up
Router(config-subif)#ip address 192.168.20.1 255.255.255.0
% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.
Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip address 192.168.20.1 255.255.255.0
Router(config-subif)#no shutdown
Router(config-subif)#
查看路由表:
Router#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.10.0/24 is directly connected, FastEthernet0/0.10
C 192.168.20.0/24 is directly connected, FastEthernet0/0.20
Router#
PC0的配置:
ip 192.168.10.10
netmask 255.255.255.0
gateway 192.168.10.1
PC1的配置:
ip 192.168.20.20
netmask 255.255.255.0
gateway 192.168.20.1
2.使用SVI实现VLAN间的通信(图)
环境:一台三层交换机,两台pc机
三层交换机的配置:
Switch>enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
创建vlan 10 20
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)#exit
配置SVI接口ip
Switch(config)#interface vlan 10
%LINK-5-CHANGED: Interface Vlan10, changed state to up
Switch(config-if)#ip address 192.168.10.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#interface vlan 20
%LINK-5-CHANGED: Interface Vlan20, changed state to up
Switch(config-if)#ip address 192.168.20.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
改变接口模式并加入vlan
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up
Switch(config-if)#interface fastEthernet 0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up
Switch(config-if)#
看三层交换机的路由表:
Switch#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.10.0/24 is directly connected, Vlan10
C 192.168.20.0/24 is directly connected, Vlan20
Switch#
两主机的配置与单臂路由中两主机的配置一样
3.跨交换机实现VLAN间的通信(图)
环境:一台三层交换机,两台二层交换机,两台pc机
三层交换机的配置(SW3)
Switch>enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
创建vlan 10 、 20 并设置ip
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)#exit
Switch(config)#interface vlan 10
%LINK-5-CHANGED: Interface Vlan10, changed state to up
Switch(config-if)#ip address 192.168.10.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#interface vlan 20
%LINK-5-CHANGED: Interface Vlan20, changed state to up
Switch(config-if)#ip address 192.168.20.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
设置接口模式并加入相应的vlan(注意trunk口的设置)
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#interface fastEthernet 0/1
Switch(config-if)#switchport access vlan 10
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up
Switch(config)#interface fastEthernet 0/2
Switch(config-if)#switchport mode trunk
Switch(config-if)#interface fastEthernet 0/2
Switch(config-if)#switchport access vlan 20
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up
Switch#
看路由表
Switch#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.10.0/24 is directly connected, Vlan10
C 192.168.20.0/24 is directly connected, Vlan20
SW21的配置
Switch>enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#vlan 10
Switch(config-vlan)#exit
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
Switch(config-if)#interface fastEthernet 1/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#exit
Switch(config)#
SW22的配置
Switch>
Switch>en
Switch#
Switch#configure ter
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#inter fas 1/1
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/1, changed state to up
Switch(config-if)#switchport mode access
Switch(config-if)#inter fas 2/1
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/1, changed state to up
Switch(config-if)#exit
Switch(config)#vlan 20
Switch(config-vlan)#inter fas 1/1
Switch(config-if)#switchport access vlan 20
Switch(config-if)#
注意:两交换机之间的链接是trunk链路
