常见的VLAN配置类型 名称 简介及优缺点 适用范围
按VLAN交换机上的物理端口和内部的PVC（永久虚电路）端口来划分。
基于端口划优点：定义VLAN成员时非常简单，只要将所有的端口都定义为相适合于任何大小分的VLAN 应的VLAN组即可。 的网络
缺点：如果某用户离开原来的端口到一个新的交换机的某个端口，必须重新定义。
基于MAC地 这种划分VLAN的方法是根据每个用户主机的MAC地址来划适用于小型局域址划分VLAN 分。 网。 步骤
1、设置vtp domain
优点：当用户物理位置从一个交换机换到其他的交换机时，VLAN不用重新配置。
缺点：初始化时，所有的用户都必须进行配置。 VLAN按网络层协议来划分，可分为IP、IPX、DECnet、AppleTalk等VLAN网络。
基于网络层适用于需要同时
优点：用户的物理位置改变了，不需要重新配置所属的VLAN，而

根据IP组播就是一个VLAN。 地理范围的局域划分VLAN 优点：更大的灵活性，而且也很容易通过路由器进行扩展。 网用户组成一个
缺点：适合局域网，主要是效率不高。 VLAN 基于策略的VLAN能实现多种分配，包括端口、MAC地址、IP地址、网络层协议等

划分Vlan成功之后，来将需要的端口划分到相应的vlan下。例如： 将F0/11划分到VLAN 40 下 sw#conf t
sw#int f0/11
sw#switchport mode access Sw#switchport access vlan 40
思考题：2900交换机支持的最大Vlan数目是多少？3500 了？ 3500支持29个。。
思考题：能否使用一条命令将一批端口一次性划分到一个Vlan下面？ conf t
int range f0/1 - 10
试验二和试验三
观察2900和3500等交换机的启动过程，IOS的版本，以及它有多少接口等。。。 配置管理IP地址和默认网关 SW#conf t
SW#interface vlan 1
ip add 192.168.0.1 255.255.255.0 ip default-gateway 172.16.0.1
清除交换机残留配置，erase startup-config 删除划分的Vlan del vlan.dat sw1为 rack62sw1 sw2为 rack62sw2
Trunk配置
设备:3500交换机 Ios:Version 12.0(5)WC17,
第一步：在SW1上配置VTP SW1#vlan da
SW1(vlan)#vtp domain norvel
Changing VTP domain name from NULL to norvel SW1(vlan)#vtp server
Device mode already VTP SERVER. SW1(vlan)#exit APPLY completed. Exiting.... SW1#
第二步：在SW2上配置VTP
SW2#vlan da
SW2(vlan)#vtp domain norvel
Changing VTP domain name from cisco to norvel SW2(vlan)#vtp client
Setting device to VTP CLIENT mode. SW2(vlan)#exit
In CLIENT state, no apply attempted. Exiting.... SW2#
第三步：在SW1上配置Trunk中继端口
SW1wangwanli#conf t
Enter configuration commands, one per line. End with CNTL/Z. SW1wangwanli(config)#int f0/23
SW1wangwanli(config-if)#sw
SW1wangwanli(config-if)#switchport mode trunk 配置f0/23交换机端口为trunk SW1wangwanli(config-if)#swi
SW1wangwanli(config-if)#switchport trunk en
SW1wangwanli(config-if)#switchport trunk encapsulation dot SW1wangwanli(config-if)#switchport trunk encapsulation dot1q 配置中继的封装类型为8021.Q
SW1wangwanli(config-if)#switchport trunk allowed vlan all 配置交换机通过中继传输的vlan为all 第四步在SW2上配置trunk中继端口
SW2wangwanli#conf t
Enter configuration commands, one per line. End with CNTL/Z. SW2wangwanli(config)#int f0/23 SW2wangwanli(config-if)#sw
SW2wangwanli(config-if)#switchport mode trunk SW2wangwanli(config-if)#
01:08:25: %LINK-4-ERROR: FastEthernet0/23 is experiencing errors
SW2wangwanli#show int f0/23 switchport Name: Fa0/23
Switchport: Enabled
Administrative mode: trunk Operational Mode: trunk
Administrative Trunking Encapsulation: isl 封装了为isl协议 Operational Trunking Encapsulation: isl Cisco 默认采用的是ISL封装
Negotiation of Trunking: Disabled Access Mode VLAN: 0 ((Inactive))
Trunking Native Mode VLAN: 1 (default) Trunking VLANs Enabled: ALL Trunking VLANs Active: 1
Pruning VLANs Enabled: 2-1001 Priority for untagged frames: 0 Override vlan tag priority: FALSE Voice VLAN: none
Appliance trust: none Self Loopback: No
第五步是在SW1上创建VLAN SW1wangwanli(config)#vlan ta SW1wangwanli(config)#exit SW1wangwanli#vlan da
01:20:31: %SYS-5-CONFIG_I: Configured from con SW1wangwanli#vlan da
SW1wangwanli(vlan)#vlan 2 name vlan 2 ^ % Invalid input detected at '^' marker. SW1wangwanli(vlan)#vlan 2 name VLAN2 VLAN 2 added: Name: VLAN2
SW1wangwanli(vlan)#vlan 3 name VLAN3 VLAN 3 added: Name: VLAN3
SW1wangwanli(vlan)#vlan 4 name VLAN4
VLAN 4 added: Name: VLAN4
SW1wangwanli(vlan)#vlan 5 name VLAN5 VLAN 5 added: Name: VLAN5
SW1wangwanli(vlan)#exit APPLY completed. Exiting.... SW1wangwanli#
SW1wangwanli#show int f0/23 switchport Name: Fa0/23
Switchport: Enabled
Administrative mode: trunk Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q SW1议是ISL
Operational Trunking Encapsulation: dot1q Negotiation of Trunking: Disabled Access Mode VLAN: 0 ((Inactive))
Trunking Native Mode VLAN: 1 (default) Trunking VLANs Enabled: ALL
Trunking VLANs Active: 1-5,10,30,40,100 Pruning VLANs Enabled: 2-1001 Priority for untagged frames: 0 Override vlan tag priority: FALSE Voice VLAN: none
Appliance trust: none Self Loopback: No
是VTP server 在SW1封装的是dot1q SW2 show int f0/23 switchport 协SW1wangwanli#
第七步 到SW2上查看是否可以学习到。。。。 在SW2通过trunk学习到SW1上所建的VLAN
配置生成树协议 SW1#conf t
int range f0/11 - 12 no sh
switchport mode trunk end
SW2#conf t
int rang f0/11 - 12 no sh
switchport mode trunk end
在SW2上 show spanning-tree SW2#show spanning-tree
Spanning tree 1 is executing the IEEE compatible Spanning Tree protocol We are the root of the spanning tree
问题1：生成树的根桥是那一个交换机？怎么来确定根桥？
根桥的选择取决于交换机的BPDU值，查看ID值和MAC地址表。两者比较最小的为rootswitch 问题2：如何知道一个交换机成为根桥？ 问题3：为什么交换机会选择成为根桥？
问题4：为什么sw2的F0/12会被阻塞？为什么不是F0/11? 开销小为根端口，其他的端口就会阻塞。
配置Spanning-tree 根桥和根路径开销
第一步 :配置SW1接口 conf t int f0/23 sw me tr int f0/24 sw me tr
第二步：配置SW2接口 conf t int f0/23 sw me tr int f0/24 sw me tr
第三步：查看那SW1运行spanning-tree的运行情况 SW1#show spanning-tree
Spanning tree 1 is executing the IEEE compatible Spanning Tree protocol Bridge Identifier has priority 32768, address 0030.1956.8400 Configured hello time 2, max age 20, forward delay 15 Current root has priority 32768, address 0001.9634.eb80 Root port is 38, cost of root path is 19
Topology change flag not set, detected flag not set, changes 9 Times: hold 1, topology change 35, notification 2 hello 2, max age 20, forward delay 15 Timers: hello 0, topology change 0, notification 0 第四步 查看SW2的生成树（Spanning-treee）运行情况
观察有无此数据
Spanning tree 1 is executing the IEEE compatible Spanning Tree protocol Bridge Identifier has priority 32768, address 0001.9634.eb80
We are the root of the spanning tree
第五步是 配置SW1的网桥优先级
SW1(config)#spanning-tree priority 1
01:23:55: ST: we are the spanning tree root 你是否将它设置根生成树 01:23:55: ST: FastEthernet0/24 become designated port SW1(config)#int f0/23 SW1(config-if)#sh
经过SW1(config)#spanning-tree priority 1 设置了优先级
再来shouw spanning-tree 得多的结果如下，（只复制了重要一行内容）
Spanning tree 1 is executing the IEEE compatible Spanning Tree protocol Bridge Identifier has priority 1, address 0030.1956.8400
Configured hello time 2, max age 20, forward delay 15 We are the root of the spanning tree
Topology change flag not set, detected flag not set, changes 13 Times: hold 1, topology change 35, notification 2 hello 2, max age 20, forward delay 15 Timers: hello 1, topology change 0, notification 0
已经成功修改成了根网桥
SW1#show spanning-tree interface f0/23
Interface Fa0/23 (port 37) in Spanning tree 1 is FORWARDING Port path cost 19, Port priority 128
SW1#show spanning-tree interface f0/24
Interface Fa0/24 (port 38) in Spanning tree 1 is FORWARDING Port path cost 19, Port priority 128
Designated root has priority 1, address 0030.1956.8400 Designated bridge has priority 1, address 0030.1956.8400 Designated port is 38, path cost 0
Timers: message age 0, forward delay 0, hold 0 BPDU: sent 483, received 2413
第七步 修改SW2的F0/23的路径开销 SW2(config)#int f0/23 SW2(config-if)#sp SW2(config-if)#spa
SW2(config-if)#spanning-tree cost 100 SW2(config-if)#
