计算机网络中的交换技术,计算机网络三种基本的交换技术(5)

2.1 接入层交换机为二层交换机配置如下（SW0为例，SW1/SW6/SW7类似）

<Huawei>system-view [Huawei]sysname SW0 #重命名交换机 [SW0]interface g 0/0/21 [SW0]vlan batch 10 20 [SW0]interface g 0/0/21 [SW0-GigabitEthernet0/0/21]port link-type access [SW0-GigabitEthernet0/0/21]port default vlan 10 #vlan 10配置 [SW0-GigabitEthernet0/0/21]quit [SW0]interface GigabitEthernet 0/0/22 [SW0-GigabitEthernet0/0/22]port link-type access [SW0-GigabitEthernet0/0/22]port default vlan 20 #vlan 20配置 [SW0-GigabitEthernet0/0/22]quit [SW0]interface Eth-Trunk 1 #eth-trunk 1配置 [SW0-Eth-Trunk1]mode lacp [SW0-Eth-Trunk1]max active-linknumber 4 [SW0-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/4 [SW0-Eth-Trunk1]port link-type trunk [SW0-Eth-Trunk1]port trunk allow-pass vlan 10 20 [SW0-Eth-Trunk1]quit [SW0]quit

2.2 汇聚层交换机作为网关的配置（SW2为例，SW5类似）

<Huawei>system-view [Huawei]sysname sw2 #重命名交换机 [sw2]interface Eth-Trunk 1 #eth-trunk1配置，连接sw0 [sw2-Eth-Trunk1]mode lacp [sw2-Eth-Trunk1]max active-linknumber 4 [sw2-Eth-Trunk1]trunkport g 0/0/1 to 0/0/4 [sw2-Eth-Trunk1]port link-type trunk [sw2-Eth-Trunk1]port trunk allow-pass vlan 10 20 [sw2-Eth-Trunk1]quit [sw2]interface Eth-Trunk 2 #eth-trunk2配置，连接sw1 [sw2-Eth-Trunk2]mode lacp [sw2-Eth-Trunk2]max active-linknumber 4 [sw2-Eth-Trunk2]trunkport g 0/0/5 to 0/0/8 [sw2-Eth-Trunk2]port link-type trunk [sw2-Eth-Trunk2]port trunk allow-pass vlan 10 20 [sw2-Eth-Trunk2]quit [sw2]vlan batch 10 20 23 #网关配置 [sw2]interface Vlanif 10 [sw2-Vlanif10]ip address 10.10.2.254 24 [sw2-Vlanif10]quit [sw2]interface Vlanif 20 [sw2-Vlanif20]ip add 10.20.2.254 24 [sw2-Vlanif20]quit [sw2]interface Eth-Trunk 3 #eth-trunk3配置，连接sw3，使用access去除vlan标签 [sw2-Eth-Trunk3]mode lacp [sw2-Eth-Trunk3]quit [sw2]interface Eth-Trunk 3 [sw2-Eth-Trunk3]port link-type access [sw2-Eth-Trunk3]port default vlan 23 [sw2-Eth-Trunk3]mode lacp [sw2-Eth-Trunk3]quit [sw2]interface g 0/0/13 [sw2-GigabitEthernet0/0/13]eth-trunk 3 [sw2-GigabitEthernet0/0/13]quit [sw2]interface g 0/0/14 [sw2-GigabitEthernet0/0/14]eth-trunk 3 [sw2-GigabitEthernet0/0/14]interface g 0/0/15 [sw2-GigabitEthernet0/0/15]eth-trunk 3 [sw2-GigabitEthernet0/0/15]interface g 0/0/16 [sw2-GigabitEthernet0/0/16]eth-trunk 3 [sw2-GigabitEthernet0/0/16]quit [sw2]interface Vlanif 23 [sw2-Vlanif23]ip address 10.23.3.2 24 [sw2-Vlanif23]quit [sw2]ip route-static 10.11.5.0 24 10.23.3.3 #配置静态路由； [sw2]ip route-static 10.21.5.0 24 10.23.3.3 #实际应用中可以使用动态路由协议，更为灵活

2.3 核心层交换机，全部为路由配置（SW4为例，SW3类似）

<Huawei>system-view [Huawei]sysname sw4 #重命名路由器 [sw4]vlan batch 34 45 [sw4]interface vlanif 34 [sw4-Vlanif34]ip address 10.34.3.4 24 [sw4-Vlanif34]quit [sw4]interface eth-trunk 8 #配置trunk 8去除vlan标签 [sw4-Eth-Trunk8]port link-type access [sw4-Eth-Trunk8]port default vlan 34 [sw4-Eth-Trunk8]mode lacp [sw4-Eth-Trunk8]interface g 0/0/1 [sw4-GigabitEthernet0/0/1]eth-trunk 8 Info: This operation may take a few seconds. Please wait for a moment...done. [sw4-GigabitEthernet0/0/1]interface g 0/0/2 [sw4-GigabitEthernet0/0/2]eth-trunk 8 Info: This operation may take a few seconds. Please wait for a moment...done. [sw4-GigabitEthernet0/0/2]interface g 0/0/3 [sw4-GigabitEthernet0/0/3]eth-trunk 8 Info: This operation may take a few seconds. Please wait for a moment...done.

2.4 PC配置（PC1为例，P2~PC8类似）
