Switch配置命令
SW-L2#接入層交換機配置
1、創建 vlan10和vlan20,並將相應的接口分配到 vlan
2、與三層交換機相連的接口
啓用中繼 switchport mode trunk
改變封裝 switchport trunk encap dot1q
3、啓用生成樹 spanning-tree vlan 10
spanning-tree vlan 20
4、配置上行速鏈路 spanning-tree uplinkfast
SW-L3-A和 SW-L3-B#三層交換機的配置
1、啓用中繼、改變封裝//在與接入層交換機相連的接口上配置
與三層交換機相連的接口上配置
2、創建 vlan10和vlan20並配置 IP
SW-L3-A#int vlan 10
ip add 192.168.101.1 255.255.255.0
no sh
int vlan 20
ip add 192.168.102.1 255.255.255.0
no sh
SW-L3-B#int vlan 10
ip add 192.168.101.2 255.255.255.0
no sh
int vlan 20
ip add 192.168.102.2 255.255.255.0
no sh
3、啓用三層交換機的路由功能
SW-L3-A#ip routing
SW-L3-B#ip routing
4、配置與路由器相連的接口
SW-L3-A#int f0/24
no switchport
ip add 192.168.100.2 255.255.255.0
no sh
SW-L3-B#int f0/24
no switchport
ip add 192.168.200.2 255.255.255.0
no sh
5、啓用生成樹
SW-L3-A#spanning-tree vlan 10 priority 0 /指定 vlan10的根網橋
spanning-tree vlan 20 /啓用 vlan20的生成樹
SW-L3-B#spanning-tree vlan 20 priority 0 /指定 vlan20的根網橋
spanning-tree vlan 10 /啓用 vlan10的生成樹
6、添加靜態路由
SW-L3-A#ip route 0.0.0.0 0.0.0.0 192.168.100.1
SW-L3-B#ip route 0.0.0.0 0.0.0.0 192.168.200.1

SW-L3-A和 SW-L3-B#三層交換機的HSRP配置
1、配置 vlan10和vlan20的虛擬 IP、優先級、佔先權、端口跟蹤和認證
SW-L3-A#int vlan 10
standby 12 ip 192.168.101.100
standby 12 priority 100
standby 12 preempt
standby 12 track f0/24
standby 12 auth xsh
exit
int vlan 20
standby 16 ip 192.168.102.100
standby 16 priority 91
standby 16 preempt
standby 16 track f0/24
standby 16 auth benet
SW-L3-B#int vlan 10
standby 12 ip 192.168.101.100
standby 12 priority 91
standby 12 preempt
standby 12 track f0/24
standby 12 auth xsh
exit
int vlan 20
standby 16 ip 192.168.102.100
standby 16 priority 100
standby 16 preempt
standby 16 track f0/24
standby 16 auth benet
